If it's between this and a perpetual logo, I'll take this any day.
I actually really like this approach. The action button isn't relevant in this context, and it doesn't occlude the content.
There's certainly situations where you wouldn't want this (ie if you're developing the app and you want to redesign starting from a screenshot), but for the average user I think this isn't overly hostile. I understand that people are dogmatically opposed to intent being modified, but I think you need to balance nuance. I actually enjoy having an attributable source in shared elements, and I think this is a low-impact way of achieving that.
I actually hate that apps are allowed to blank out content on screenshots, and this can't be disabled. There are apps completely mis-using it, e.g. mobile payment apps which hardly show any sensitive data in most cases, but now I can't share e.g. infos on screen with someone else easily.
It's a classic case of someone discovering a feature and thinking "hell yeah, so much security" without understanding or caring about UX impications.
I've yet to see someone saying "oh, I'm so glad my screenshot was blacked-out because I didn't realize I was in a banking app". It feels patronizing.
> I've yet to see someone saying "oh, I'm so glad my screenshot was blacked-out because I didn't realize I was in a banking app". It feels patronizing.
Yes, this. Payment apps, government apps, IM communications.
The other day I almost rooted my phone in anger trying to get around this, before pausing and realizing that this would only cause even more problems with those apps, thanks to remote attestation "features".
My favorite recent case, I almost locked myself out of mobile government services when changing phones recently[0], and it would've made for a stellar bug report showing when "fail safe" design can easily become "fail deadly"[1], with UI view of access and invalidation history clearly showing the timeline of a problem... if only I could take a screenshot of it. But I can't, because "much sekhurity".
--
[0] - Well, it's not really that big of a deal. With government services, there's always a way back. Might involve walking to a local civil affairs office or, worst case, a police station or a notary, but there is a way back. Big cloud services, on the other hand...
[1] - Invalidating a certificate prior to issuing a new one sounds like a good security idea, but in the real world fails critically if the two operations aren't an atomic group. In my case, issuing a new certificate failed, and I ended up walking around for half a day with old one invalidated and not even knowing it.
On a similar note in terms of frustration, my bank ended up getting me to memorize my randomly-generated passwords twice because it blocked pasting. I guess it's to discourage writing them down in plaintext files, but I bet it just makes most people choose meaningful (and therefore weak and guessable) passwords.
Software that intentionally subverts the intent of the user is malware. We now live in a world where most financial institutions literally ship malware as their primary or only interference to access their systems.
I understand the sentiment, but think about the non-technical user. Every time I use my mothers or any elderlies phone there are a lot of screenshots in the gallery, because they accidentally click the combo. How many people get scammed using screen sharing? It isn't that unreasonable to prevent this vector just to be more safe, especially if the bank might be partially at fault if a scam happens.
People also take pictures of their government IDs (passports, drivers license, etc) and utility bills.
Should the phone identify those things and automatically blur out all of the sensitive information in those photos too?
I’d prefer if my phone did neither that nor told the apps that a screenshot was being taken nor allowing the apps to hide anything that was on screen when a screenshot is taken.
It’s my phone, I want to decide what I take photos and screenshots of.
> especially if the bank might be partially at fault if a scam happens
That's the crux.
Yes, it is unreasonable, because scams have proven to be just as effective at getting people to just read the details out over the phone line, and bank these days are not showing much sensitive information in the open anyways (my recent annoyance - someone thought it's a good idea to never show the full account number on screen, showing just first and last few digits, and an option to copy to clipboard...).
Meanwhile, those very apps tend to be ones people would most often want to screenshot for legitimate reasons - e.g. to communicate or make a record of specific transactions, accounts, their states, metadata, etc. None of which is copyable text in the app, and most of it isn't even properly exportable, so it's not like there's any other way.
Unfortunately “are you sure?” checks simply don't work, too many people are trained to just click yes/OK to close the message and get back to what they were trying to do.
Hoping to not sound like a broken record, this is why having full ownership of your device and OS is important. My stock Pixel Android recently told me something along the line of "A security policy blocks screenshots for this app. Talk to your administrator if you want to change the policy". I looked in the mirror and my administrator said "time for a policy change, we're moving to GrapheneOS".
And just as important: Help your friends and family to move as well, so they can have ad blockers, NewPipe etc. We need a critical mass of users invested in their freedom, otherwise its going to be crushed by malicious/dumb security measures of their banking apps, corporate greed ("oh, a simple misunderstanding, when you clicked 'buy' you rented a limited license. Did you not read the ToS?") and police overreach. It's a perpetual battle.
“Security” that makes ordinary sharing unusable is often just UX debt wearing a security badge. The right fix is selective redaction, not disabling screenshots everywhere.
> “Security” that makes ordinary sharing unusable is often just UX debt wearing a security badge.
Very true.
> The right fix is selective redaction, not disabling screenshots everywhere.
That's still a partial fix, though. It would address the problem of accidental screenshots in a better way, but the main point of contention is around intentional ones. Here, the problem is that the app vendor and the user have different notion of what is "sensitive".
I went to screenshot my upcoming Verizon Fios fiber install out of excitement and got an immediate warning dialog.
WARNING: You are in violation of the My Fios app end user licensing agreement that prohibits duplication of this screen. Please immediately delete this from your device.
... apparently buried in the app T&Cs is a "Distribution of the technician's picture or information is prohibited". Even if there's no tech assigned, the screen with the picture of the grey fake man with a fake hat apparently causes a big old warning if you screenshot it.
This is phone OS developer's fault for even allowing it. When I take a screenshot, I expect to have an image of exactly whatever was displayed on the screen at the time. Its not a picture of your app, its a picture of my screen. Some banking apps used to (or still) prevent this and now some apps get a hook to insert their branding. My device serves some master other than myself.
It’s so if an app is showing a password or bank account number or other piece of sensitive information it doesn’t accidentally end up in a screenshot. I think there are other places sensitive information won’t show.
Bluesky, and apparently others, are abusing the functionality for advertising purposes.
I think it’s a good thing it’s there. This functionality should be easy for apps.
I’d say this is one for app review or an App Store rule. But we all know those are a total joke.
I don't have an issue with BSky's use, but I regularly run into the functionality's abuse elsewhere, such as multiple of the biggest Thai banks' apps where every screen in the app entirely blocks screenshots (iOS). Doing a P2P money transfer and want to send a screenshot to the recipient for them to confirm their info before you hit submit on a non-reversible transfer? Blocked. Want to screenshot a promotion's terms for proof or a personal reminder? Blocked. It's even worse as multiple of the biggest brick-and-mortar Thai banks wholly dropped web access and are now smartphone-only. (Or more obscure, want to translate a single-language screen into another language? Blocked.) Etc.
>Doing a P2P money transfer and want to send a screenshot to the recipient for them to confirm their info before you hit submit on a non-reversible transfer?
Why not ask contact for data via text and just copy paste it with double check?
What if the app doesn't allow pasting? What if the communications app prevents copying?
For a short while, screenshots were a workaround for blocked copy-paste[0], as OCR (and, more recently, edge-deployed vision-enabled language models) would allow you to copy and paste any text from a screenshot. But guess what, now every other app is blocking screenshots!
--
[0] - Which is the default on mobile apps, and unfortunately desktop apps too. I hate webshit applications, but if they have one redeeming grace, it's that by default, all text can be selected and copied, and it takes nontrivial engineering effort to break that, so most webapp vendors don't bother.
1. On the pre-submit-button screen it shows the recipient's name to confirm, but as in the GP example, if the recipient's name is in a character set different than your own, it would be nice to be able to have someone who can confirm the recipient's name matches.
2. And even if you copy-paste the recipient's account number, that also relies on your counterparty not having mistyped their account number, so it would be nice for #1 to be possible to confirm the name.
I want to take a screen shot of the transaction I just did. Can't because some ahole decided for me that it's too sensitive information and blacks out the whole screen. this API is stupid without control in settings of the os
Yeah, I used to have this issue a lot. If I use my personal card for a business expense, I used to like to keep a screenshot of the transaction on the card as well as the invoice. As it's an app-only challenger bank, this is the only way short of exporting transactions as a PDF and that includes other transactions for the day. For a long time I used to use another phone to take a photo of my phone screen. Eventually, I just stopped bothering taking that photo because of the extra hassle, but it never stopped annoying me that I couldn't keep the records I wanted easily.
Yeah, I would rather see a warning in that case that the screenshot could contain sensitive information, with options to take a redacted screenshot or a normal one.
I mean... "please read me the code you get via text" or "this really Bank of America, please type your OTP" seems to work well enough. We really don't need OS-level controls for stuff on the screen. People can just tell you what's on the screen.
Often, you don't, because the same developers of the bank app decided it's an unnecessary power user feature that doesn't fit in the MVP or something.
Or, even if they add it, there's no way to save the file, only to "share" it, which 99% of the times isn't what I want, and I'm frankly tired of routing through the mail app as a workaround. At this point, at least on Android side, there exist apps whose sole purpose is to be a share target and dump the information to file (and being apps on an app store, chances are top 10 are just thinly veiled malware).
really? I'm not suprised by shitty developers developing shitty apps but i'm still baffled. Surely the bank would be getting tons of angry emails from customers if it happened in europe
They probably support proper export for business accounts. Business customers have leverage. Regular people? They're an annoying but necessary nuisance.
>It’s so if an app is showing a password or bank account number or other piece of sensitive information it doesn’t accidentally end up in a screenshot.
and also coincidentally if the app is showing something incorrect that you want to be able to verify and provide proof of now you can't.
>I think it’s a good thing it’s there. This functionality should be easy for apps.
I think it's a bad thing it's there. The functionality should be easy for me.
OTOH, I might very well want to take a screenshot of my own bank details, transactions, or other sensitive information. It's annoying that my information is being protected from myself.
You might have amazing operational security but lots of other people don't, and they make noise, which means governments write laws meaning that banks have to refund them for fraud.
So as much as a bank might agree with your stance on freedom of compute - they probably don't want to pay for it with actual money.
Banks have managed to externalize the costs of their own security onto people by inventing the concept of "identity theft", and pinning the blame for poor security practices on regular people.
They really shouldn't be allowed to double down on it.
And arguably, half of it isn't even really security, it's about keeping you in their app. Application interface is the ultimate sales platform, and banks are making extensive use of that fact.
Then it's a bad solution to a real problem. A better solution would be exposing a hook that apps can call when a screenshot is initiated that tells the OS to warn the user before saving the screenshot. This way the user is actually educated on the risk while still respecting their right to control the outcome.
The OS could draw an ugly censoring block over the sensitive information. That would protect the user's privacy when needed but also prevent apps mis-using the feature like this.
It could. But the root problem is, there is no such thing as unqualified "sensitive information". The information is sensitive to someone, for some reason. The problem with screenshots manifests when the app and the user disagrees about whether the information is sensitive and who has the right to control it.
The immediate technical problem is that OSes allow apps to declare what is "sensitive", and then follow those declarations unquestionably, preventing any preservation of that information.
The underlying social / political problem is that platform vendors allow app vendors to unilaterally declare what is and isn't sensitive, and proxy their opinion without question, and with no consideration for users and their context.
I don't think Apple cares about apps replacing the follow button with an icon. It's a weird use of the api, but it's not abusing the user or a security/privacy risk.
This shows hardware won't be yours unless the software running on it is open source. Asking a company to modify its closed source software might work occasionally, but it's a band-aid and a never-ending battle.
Your banking app probably has an option to disable that because it's a legal requirement in so many places: People who can't see need to use assistive tools, and that includes screenshots and friends. If you are using a tiny/stupid bank in the US, file a ADA claim and get some money. In the EU check your Ombudsman.
No, it's so you can't screen-record Netflix. The bank doesn't care about that because it's not a liability issue to them, just fetishism; no way they pay Apple and Google for this capability.
Apple and Google should step in and allow users to remove these shenanigans with a little button on the screenshot preview screen, but resist this because of Netflix et al.
I don't think they're abusing functionality at all. I don't think screenshotting a skeet should, by default, leak the follow state of the user taking the screenshot, which is what would happen without the secure input swap
"Secure inputs" take many forms, and it doesn't feel like this is abuse in any meaningful way
The side button (https://support.apple.com/en-gb/guide/iphone/iph7d116e557/io...) is on the exact opposite of the volume up button. Pressing the side button to shut down and lock the screen is something I do a lot. Press button (2) with the thumb and you will see that it is very natural to have your index or middle finger resting where the volume buttons are.
And occasionally I press hard enough with my thumb that the finger on the perpendicular side of the phone presses the volume up button and whoops I have taken a screen shot instead.
That said. I do consider this "feature" an abuse of privacy API:s, and I also often get annoyed that I cannot take screen shots of my bank app to for example send account information, or confirm a transaction, or report a graphical bug to the developers at the bank.
Consider that people use their phones differently than you. I take screenshots on a daily basis, accidental ones at least once a week. Usually it's just the lock screen though.
You're not that unlikely to leave that feature in place if you have such an operating system. What you really want is two controls: one for "safe screenshot", and another for "raw screenshot".
They are imo clearly gearing up to lock down passkeys in practice one day so that you will only be able to use those tied to a Google or Apple account (or some new player). They're already threatening in these issues to blacklist open implementations that don't submit to their requirements, and then requiring an attested client would then become the "best practice" adopted blindly and widely. I think the only hope is for the open clients to fully submit, hoping to avoid full attestation, while not making it too hard to patch out the anti-features. Of course, anyone who can't compile is screwed though.
If a dev forgot to obfuscate the password and rendered it as plain text on the screen, then what are the chances they remember to program the blur into this screenshot api hook. Or why not add an alert, “what me to blur sensitive info? Yes/No”
Unfortunately there's platform-level features for marking surfaces as sensitive/secure. So your dev would typically just mark the whole app as such, and be proud of their proactive problem solving.
The app doesn't know. It just produces a widget tree, and the OS-provided renderer renders it this way or that way. In particular, it chooses not to render controls marked as "security-sensitive" when the rendering is intended for a screenshot; it could instead put empty boxes in their place, etc. The app has no idea and no control, AFAIK.
Open the amazon app. Take a screenshot. See a toast message informing you that the amazon app has detected you've taken a screenshot. Fucking used for fucking profiling.
Snapchat advertises that they detect screenshots. They try. But they're well aware that they can't actually know.
For example, their bug bounty program policy helpfully informs you that "screenshot detection avoidance" is not considered a vulnerability: https://hackerone.com/snapchat . That's because it's always possible.
I wonder if this is the expectation of the majority or just the expectation of us tech people.
Because I assume most people want to take a screenshot because they want to capture something they are seeing in the app, most people probably are even annoyed to have the system indicators visible there.
Bank apps black out the whole screen when I take a screenshot and it’s super annoying. As a user, I should be able to take a screenshot of my screen. I can use a camera or another phone to do it anyway.
Reddit has a toggle in its settings to disable it. X, too, I think.
Personally, I wish iOS didn't even facilitate this.
edit: to be clear, I don't think iOS should notify the app at all. The app could register areas as "invisible to screenshots" perhaps - I'm torn on that functionality.
That's what bluesky is doing in this case. It is showing the button on an area that is "invisible to screenshots", and the butterfly is behind it, so it shows through when a screenshot is taken
> and now some apps get a hook to insert their branding.
No, apps can already insert their branding anywhere they want. They're writing the app. If they want their logo to be visible in screenshots, they have infinite ways to do that.
This particular way seems basically prosocial. It's much more useful to me as a consumer of the screenshot to see that it came from Bluesky than to see that there was a "Follow" button. It's not what the feature they're using was intended for, but I can't call it an abuse of the feature. What they're actually doing is good.
The fact that you're getting unexpected behavior isn't good. Sometimes you want to create a picture of sensitive information. You should be able to override the app developer's security settings.
The thing that really irritates me about the banking apps blocking screenshots is that it's pretty clear to me it's not about protecting customers but denying customers the ability to document something related to their account.
No, it's about saving the bank money - and what costs them a lot of money is the average person being fooled into sending people their account information easily.
> I expect to have an image of exactly whatever was displayed on the screen at the time
Do you/should you (we) really expect that though? I regularly use color filters on my apple devices— grayscale to avoid distractions during the day and red tint at night. More recently I’ve been using the motion dots. I don’t know that I can say with confidence that I never want any of those “personal-perceptional-modifiers” to appear in a screenshot, but for most folks, I would guess it’s approximately never.
The effects of cramming 2 separate workflows and 5 features into one thing called "screenshot" because anything else would end up with something too complicated for users to understand the interaction (sarcasm that figuring out what the behavior is locked to in these scenarios is just as confusing).
While we're at it, this "share" containing the copy/paste flow is the exact same kind of thing. And screw whatever logic decides to copy the URL of an image instead of the actual image sometimes from Safari when I select to copy it!
This is in fact a watermark to promote the application, which otherwise wouldn't be recognizable since Bluesky looks like every other microblogging app. I didn't know that Sam literally named the file GrowthHack.tsx, which is pretty funny.
Well, I have not once found a single case where an app reacting to screenshots and controlling the process in any way was anything to me but hostile and annoying. This one does not help.
It somehow is perfect example of how modern software engineering feels to go astray for me. A feature in my device working completely in benefit of the one providing said software. I wish, and wish only I can, that this trend goes away at some point.
It is actually astonishing to me that this is not something which can be turned off at the OS level, or as a permission setting in the app permissions.
The app knowing I took a screenshot feels adjacent to me to a keylogger. Imagine how many apps are capturing that information silently. To my mind, a screenshot is something that is happening outside of the app context, the app knowing about it is a security flaw imo.
> The app knowing I took a screenshot feels adjacent to me to a keylogger.
To my knowledge, this is a misunderstanding.
The app does not know that you are taking a screenshot, rather iOS knows you are taking a screenshot (as it must) and is excluding an element on display that has been designated by the developer as sensitive information.
This is the same technology that prevents you from accidentally screenshotting your password manager; the developer has simply performed a nifty trick to display a small icon behind where the “follow” button would otherwise be displayed.
There are plenty of instances where this sort of thing can be annoying, such as when you try to screenshot a streaming service app and DRM enforcement leaves you with a blank screenshot, but IMO this particular instance is actually very tasteful; seeing “follow” on every screenshotted post is just useless noise, but a small unobtrusive platform icon is a useful reminder that the post came from Bluesky and not another very visually similar service like X(cancel) or Mastodon.
This prevents us from taking scrolling screenshots (a native feature in many smartphones today that is often useful when there is more than one screen of content).
I dislike this hijacking for that reason and wish there was a way to turn it off.
If you screenshot what you are listening to, after the screenshot is taken spotify will open a full-screen popup to "share" the song you are listening to. This is quite dumb, especially since if you wanted to share a song via the screenshot, you can do so in the OS-level screenshot UI, and then you would close it and see Spotify's own similar version of the same UI. Spotify just really wants you to use their own share button so that they can track you.
I’ve seen another app do that but for a different reason. It’s for security cameras and they use it to show a “hey idiot just press the save a picture button, don’t take screenshots” popup, which is also hostile.
I’m not sure why the app needs to be notified. There must be some use but I can’t think of it off the top of my head.
> I’m not sure why the app needs to be notified. There must be some use but I can’t think of it off the top of my head.
My pet theory: it's because Snapchat got big early, platforms added the feature to facilitate Snapchat's business model, and then banks started abusing it, and it stuck around "because sekhurity".
Anyone can take a "snap" of the phone screen with another phone's camera so this is a losing battle anyway.
It amuses me that browsers in incognito mode refuse to allow screenshots on mobile. But same browser running incognito on a desktop can be merrily screenshotted. What is the difference they are trying to enforce based purely on device form factor/OS.
Very interesting!
Parent poster is correct, that notification does feel akin to a key logger… although I’m not sure that it applies to this bluesky feature.
So in this instance, am I right in understanding that iOS posts a notification after the user has completed a screenshot, which would make it impossible for the developer to use this notification to trigger anything that would modify that screenshot? Hence the developer’s work around?
> This is the same technology that prevents you from accidentally screenshotting your password manager
Yes, and I would say it's a bad thing that the OS tries to prevent this.
> seeing “follow” on every screenshotted post is just useless noise, but a small unobtrusive platform icon is a useful reminder that the post came from Bluesky and not another very visually similar service like X(cancel) or Mastodon.
I would say it's a bad thing that Bluesky makes the screenshot look different from what was on screen for the user. If I cared about excluding the "useless noise" from a faithful depiction of the pixels on my screen, I could address that myself.
As someone who develops apps for confidential conversations, making it harder for people to screenshot the confidential stuff is a feature the sending party wants, that is why they send in your app as opposed to others. It doesn’t make things impossible, just hard enough that 95% of people won’t bother to take a copy.
Same for example with disappearing audio messages on whatsapp
What I don’t like is the app being informed that I took a screenshot. The OS can hide things in screenshots without this.
One user wants it not to be shared, but the other user might have various reasons to want to take that screenshot - maybe it's evidence of something they need to share urgently with others, whatever. It's definitely hostile to that other user. I get why you'd set it up that way, but it's a tension that really goes against the "full control of your own device" ideal a lot of people have.
Don't send me anything you don't want screenshotted. Easy-peasy. I'll accept an opt-out of whatever protections are in place for the general user, but I don't accept that those protections should remain in place for all users. It's hostile.
It's mostly dumb because of obvious analog loop holes. I at minimum carry 4 devices with cameras, often as many as 12. If I want to capture the disappearing message... I will do it; making it annoying just makes me pissed at the developer + the is.
> Yes, and I would say it's a bad thing that the OS tries to prevent this.
Another way to look at it is the OS makes certain guarantees to the developer around security. Giving control of this to the user would erode that guarantee from the OS to the developer. The result of that is that some developers would simply never display some information (e.g. due to their own contracts or reasonable concerns about fraud/abuse/etc.).
Very similar to the video pipelines in modern devices. Prior to video pipelines which the OS could attest could not be hijacked by the user, many content providers simply would not allow e.g. Netflix to release their content on certain platforms. That the OS does provide such an attestation option for developers allows uses that otherwise would not exist.
"The app does not know that you are taking a screenshot, rather iOS knows you are taking a screenshot (as it must) and is excluding an element on display that has been designated by the developer as sensitive information. This is the same technology that prevents you from accidentally screenshotting your password manager"
And that is reasonable, but it is also a surface where an app touches the OS, which should be a permission boundary that I can control. Allowing the option to opt-out of screenshot blocking with a proper double-confirm warning and biometric auth is also reasonable.
The OS notifies the app after the screenshot is taken. The app doesn’t get to do anything in response to it being taken or allow it to be blocked.
They’re abusing an iOS text rendering control function handled by the OS. Before the screenshot is taken iOS swapped out the rendered text for “sensitive” fields and images that.
The replacement is supposed to be something like a masked account number, password asterisks, or just general blur.
> This is the same technology that prevents you from accidentally screenshotting your password manager
I should be able to screenshot anything I want, including my password manager. I should be able to opt-out at the OS level, or any other level that enforces it. That's why it's definitely a user hostile feature.
Neither of those use cases seem good or tasteful to me as a user, I don't think this concept of "secure (from the user) context" should exist, but maybe that's just me
the other device then likely indexes it after a brief once-over by its own ai-enabled os. any crossover interactions, and it may as well be the same device. maybe some of you have not experimented enough with the theshold to have noticed yet.
I think bsky's use of this malware feature is as benign as it's possible to get, but it's still a malware feature. As you point out, the real reason this exists is to enforce DRM and make your computer serve Netflix et al rather than the person who owns it.
> accidentally screenshotting your password manager;
I could not think of a more useless justification for installing malware into the OS. Okay, you've accidentally screenshotted your password manager. So what? Are you going to accidentally upload it to the internet too? I'd much rather live in a world where people who are that stupid face minor consequences for their actions than one in which all of our own computers are used against us.
As with most things, it would be ideal if we could have both good defaults to make things accessible and advanced user controls to allow users to retain control.
That’s a rare mix these days.
People like to say that. How many hundreds of additional options would a modern phone OS need to provide that though? How could applications possibly be tested?
You could have a million installs and 300,000 of them could easily have fully unique combinations of options past what’s available today.
How could you ever provide support to a user? “First take 200 screenshots and send those to me…”
> The app knowing I took a screenshot feels adjacent to me to a keylogger.
That is what this article is about and why you should read it before commenting. The whole point is that it doesn't need to know you're taking screenshots. That's why it's a clever trick.
I guess it would need permissions, but you can monitor the photo library with PHPhotoLibraryChangeObserver and check if a new item's subtype is photoScreenshot.
Otherwise userDidTakeScreenshotNotification only fires for your own app
but you didn't read the part where the mechanism is explained? it doesn't do anything like capturing information. it just marks a button "sensitive" causing it to be hidden in a screenshot, thus revealing an icon that was put there underneath the button.
Did you read the article? Bluesky doesn't know you're taking a screenshot, iOS just hides the follow button in the screenshot (consequently making the Bluesky logo visible).

If someone from Google Maps or LinkedIn team is here, please, when I take a screenshot it's because I want to a screenshot, not share the friggin location/post.
Not sure who got the idea that it was useful, it isn't.
I would happily use the Google Maps "share" feature, but I've yet to encounter any but the simplest of scenarios where it actually preserves the entire context of what I'm trying to share: the viewport, the start and destination, stops along the way, route choice, the time of day, all of it.
If I'm sending a screenshot it's because I want to send exactly what I see on my screen and not have my recipient's gmaps instance happily recompute a route it thinks is better or leave out the routing information I included, or switch from biking to driving directions, or whatever else.
It's of course about lock-in. In the early Web-GIS era there were a few competing but popular notation standards for sharing lat/lon/zoom/<sometimes more> that was meant to be human readable and compatible with any WMS or similar.
Ah... to imagine a world where you could just share a coordinate string and people could open it in whatever map app/page they wanted. Geo URI is probably the closest we have today but I don't think much of anything outside the OS Geo community accepts it.
I think that's actually a separate issue. What I specifically want from a Google Maps share URL is for it to be something I can send over text that will reproduce for my recipient exactly what I see.
A lat/lon/zoom/start?/dest? is kind of what a Google Maps share currently is, but it's neither an interoperable standard nor a reliable capture of the current state, so really the worst of both worlds.
Hi! I think I’m on the same page (give or take a zoom level) now. That is hard to do between separate geodatabases (hence CRS, placenames, geocoding, etc.) but Google isn’t even doing it within their own. And the only way I can obtain a link is to first place a pin, which wants to snap to nearby features. If I try to link a nice trail near my home it snaps to the quarry instead, making me look like a maniac with a terrible idea of what a “quiet walk” looks like.
I've noticed similar things with off-road biking as well. Hydrocut generally does an okay job of snapping to the trails there since Google knows about them, but I was at Rondeau this weekend, and Google kept insisting I was on the adjacent Lakeshore Rd rather than the Harrison trail [1] that I was actually on. And this had real consequences because my youngest and I had become separated from the rest of our group and were trying to use a "share my location" through Signal, but the Android system-supplied location used was the one that had been unhelpfully snapped to the road.
The other reason someone might want a screenshot specifically isn't to share a location, but to share a route. For instance, I might want to text a friend a screenshot of my driving route. Maps can sometimes route weirdly, so this is definitely a use-case I've needed before.
I have a seething hatred for google maps links people send on mobile because Google no longer shows you the map in your mobile browser. It has for at least a year or twoo required Google Maps be installed to show you what the person linked to.
From the same lunacy that forces me to write my 30-something character Wi-Fi password on a "secure password field" that only shows me the last character, almost ensuring that I will make an unlimited number of typos and spend way too much time for something that should only take 30 seconds.
It's not clear who it is protecting against, it does not seem to be effective at protecting against anything at all, it is actively annoying to the user, and has no way to disable. Perfect example of the usual "security theater" feature.
That seems oddly user hostile for apple. Especially for Wi-Fi passwords, which are a very common thing to share. Android has had a feature for years that generates the password as a plaintext-encoded QR code so you can share a wifi password without the other party even needing to type it in. And at least on my pixel 9, I have a toggle on the password entry field to toggle visibility.
I don't have an iOS device handy to compare against, but it surprises me that Apple wouldn't also recognize that Wi-Fi passwords in particular are extremely common things to share.
Unsecure: open Shortcuts, tap Gallery, search “Adjust Clipboard”. Add to Action Button folder and run from Action Button. - Or add “Dismiss Siri and Continue” action after “Get Clipboard” so you can say “Siri, Adjust Clipboard”.
Type in the still-unreasonably small window, tap Done, paste password. (Then clear clipboard I suppose and consider privacy implication if your clipboard syncs to Mac.)
Apple gave too much power to iOS developers. They can use DRM strong enough that when your iPhone is open in iPhone Mirroring on your Mac, and you record your Mac screen with a third-party tool, the iPhone screen is blacked out.
I bet this is the inverse problem. Someone thought "oh a prescription is definitely privacy sensitive information, I should ensure the OS does the right thing" not realizing this counter productive behavior.
Yeah, health information is interesting in general because it needs to be kept strictly secret from unauthorized people, but people also often need or want to share their own information and have every legal and moral right to do so.
Major reason I don't use password managers that much.
> Do you use the same password on every site?
I use a password I can reconstruct in memory for sites I care about logging in by hand. If I don't, or don't mind resetting my password each time, I just use random garbage + whatever platform password manager is the one active today, with vague hopes that it'll still be there the next time I need to log in.
> How do you deal with data breaches?
Who ever cares about those? I'm yet to hear about anything impactful being released on those. It only matters if you actually do reuse the same e-mail/login and password combinations on both important sites and garbage sites. Which is something you should not. But 2FA and magic links tend to solve that vendor-side, these days.
I use KeepassXC and Syncthing. It's not a single password manager doing both the managing and syncing, but it works very well, and I sync between phone/laptop/desktop without any third parties.
Keepass database is an openly documented format, and there are several apps available on iOS that use it and can store the database in your iCloud (ie syncthing is not required, unless you need to sync to non-iOS devices)
Just search for keepass in the app store (Keepassium, KeePass Touch, Strongbox, ...)
I thought your other comments about writing your own were sarcasm about how that's such a terrible situation if that's the kind of thing it would take.
But this one looks like you actually mean it? Yikes.
Good thing if you have GMaps open to the directions list while driving and tell Siri to take a screenshot, it doesn’t throw up a full page of nonsense over your directions that only Voice Control (not Siri alone) or a [potentially nonexistent] passenger could close.
> Hijacking the screenshot process is a privilege that you ought to be able to revoke, it's insane to allow software to be given more control.
It should not exist as a control in the first place.
I know it may sound absolutist, but the way I see it: if you allow this as a user-revocable permission, then the very apps that need to be screenshotted by users most often will be the first to refuse to work at all unless you grant this permission.
Screenshotting is an system operations level feature. Apps should be neither aware of, nor able to interfere with, a screen capture being taken.
Did you read the post? Nothing is hijacked, but its a trick where they render the normal button in a ui element for secret data, which is blanked by the system on screenshot, revealing the logo underneath. Its a reasonable feature, so its hard for apple to control it better or remove this.
That is a lot of words just to make it sound reasonable that a page can be exempt from the underlying screenshot functionality. It isn't. Not without asking the user.
No, it’s not a reasonable feature. If I take a screenshot, I want the image to include what is displayed on my fucking screen, period. What is so difficult about this?
When I take a screenshot in ChatGPT, it shows a "share this chat?" toast at the top.
The toast shows up after the screenshot, but my phones's long screenshot feature captures the top part a second time, so the top part of the chat becomes unreadable.
Yup, that's by design. They want to force you to "share" so they can both track who you interact with, and also try to convert the other person into a paying customer.
There should be a layer of user control where the user can make the OS lie to the app. The app has no need to know when a screenshot or recording is happening, what the real location is, what file system contents are, etc.
Side note- The Screenshot culture itself needs to die, sorry. Many a time, a share button simply works. I don’t know why people would share a screenshot or a map instead of pin and share their location. Yes there are cases where a screenshot helps but majority cases simply is “come to this place” a which turns out to make more difficult because people apparently don’t know how to share locations with pin and share!
Screenshots are much better for archival. So many times you go back to a url/link you shared, and poof it's gone or the content has changed from when you sent it.
Screenshots allows you to get a point in time reference to what you are sharing.
In the case of sharing a link I have to remember/find where it is in each app, likely scroll through a long list of messaging (and for some reason non-messaging apps) to find the correct app, select the contact, and then pray that the link sent actually works for them and contains the correct information I'm seeing (very often the link will actually direct them to a web version of the app I'm using, then put a modal popup in front of the information asking them to use the app, then either send them to the app store, or send them to the app but strip out the actual information I linked and send them to a blank map).
Screenshots are clunky and unideal, but at least they're fast and I know that they don't fail or break or send the wrong info to my contact.
If it were a one off message, this wouldn't be an issue, but if you zoom out on the issue and see you're sending up to a hundred messages a day, points of failure become major life frictions and you're trained out of using things like links in messaging apps.
The ideal "World Wide Web" envisioned by it's original design, was that a URI was a durable pointer to an immutable piece of information.
In 2026, we now know that the information can be edited, or completely removed for many reasons, some legitimate, and some nefarious.
Taking a screenshot is the easiest way to ensure the original is kept for folks to see. Frankly, it'd be even better if (a) the app can signal to the OS information about the url to the page for the screenshot, (b) timestamps were captured in the image and not cropped, and (c) the OS can authenticate the screen shot and digitally sign that it came from an unaltered device.
I totally disagree - the few times I accidentally use a share button, or are forced to use one, the experience is so desperately miserable I am forcibly reminded why I never use them. It's always several clicks, choosing the social platform I need from the millions-long-list which is paginated into pages of like 4 icons at a time (I just want a URL! but you broke your website to force users into the app!) and from there choosing a specific chat or group or whatever from a poorly ordered list that starts with some person I met at a bar twelve years ago rather than the chat I was literally just typing in two seconds ago...
and then when it does send I have no control over the presentation on the other side. Sites love to add some cringe "I love this app SOOOO much hearteyesemoji fire fire fire... sent from my iPhone, made with love in san cupertino" nonsense in my own voice - literally sending their words into my chats using my account, as though I had written their marketing dreck
I also despise this "screenshot blocking" stuff. A device listens is supposed to me, not to the apps. I want a screenshot to be a copy of the raw pixels, and an app should not know about it or have a right to know about it.
Of course this is doable on open source OSes like GrapheneOS, it just sucks that you have to keep modifying the OS every time they release a new version
This is what made me avoid chrome since release, I tried to right click a youtube channel background as a teen wanting to use it as a template to make my own channel background on photoshop... turns out they had disabled it, while I could on firefox.
Nobody in the comments talking about snapchat where like one of the core pillars of what "sets their service apart" is the difficulty of taking a screenshot without notifying the other party
Wasn’t that the entire premise of the product when it launched? Disappearing messages and minimal footprint so you could be confident your communications were semi-private?
That was the expectation of using the product so it fits and isn’t anything like this discussion.
Yes. And because of the platforms deciding to enable that business model, we're now in a bullshit reality where the very apps that need to be screenshotted most often, are first to abuse platform features and prevent screenshots from being taken.
This deserves a longer rant, but the very premise of Snapchat was always poisonous, and is largely responsible for why, 20 years later, we're now facing extreme proposals for regulating electronic communication.
I generally disagree with the whole line of criticism techies get for "solving social problems with technology", but if there's one unambiguous case where I'd agree it was plain stupid, it's the concept of screenshot prevention, that became prominent with Snapchat. Controlling whether your recipient gets to keep the message you sent them is a purely social problem, and the answer to that in the real world has always, for good reasons, been "once sent, it's no longer yours; once received, it belongs to recipient to do with as they please".
> but the very premise of Snapchat was always poisonous
Wdym? Hooking (primarily underage) people onto "daily streaks" of sharing (often inappropriate) pictures of themselves to (sometimes random) other people via likely insecure servers is a _great_ business model!
Great customer retention. Lots and lots of engagement. So much shareholder value.
Their entire color story was really cool at the time. Yellow with Magenta/Blue accents was super bold, especially compared to the boring ass direction everything was going. Material and Windows 10 flatshit was all the rage and here comes Snapchat like the Kool-Aid man.
Not only 'pocket computers' are an issue.
I was thoroughly shocked when I found out that websites can detect that the dev-tools are open. That is something that a website should never be able to know, yet here we are.
They don't respond to it. It simply says "this button is part of sensitive content", and the OS itself hides the sensitive content, revealing the image below it
have you never encountered the plague of apps saying "don't screenshot, our content looks so much better when you share it, see:" and then displaying a picture of the stupidest looking thing youve ever seen in your life as though you would ever consider showing that to your friends instead of the most personal thing - literally showing them what youre seeing with your own eyes
On iOS, if you swipe control center down and then back up but don’t lift your finger, the screenshot will not have the logo. I do this with Twitter so my screenshots don’t have the X logo.
Interesting that this works. I know I have been frustrated recently when trying to take a screenshot of a bank transfer or something similar, but I couldn't find which app that was to test again. I tested on the iOS Passwords app, and I couldn't get the trick to work in that. I wonder if I'm doing something wrong, or it only works in specific apps.
Each time I tried to take a screenshot of a password, the password was missing from the screenshot - even when I kept the control centre pulled down far enough that the Password app was starting to look blurry.
They shouldn't even disallow screenshots from a security measure. If the user wants to take a screenshot of their bank account info or a password manager they should. Maybe an additional permission for screenshare. No device has protection against a second device taking a recording so it's really just security theater
It's all "security" and all until your banking app has a bug that breaks exporting bank statements and the only way to get it out is to take screenshots - which are blocked as well. Oh, and you need to submit it by today.
At least on rooted Android devices you can bypass that.
I'm confused why people are mad at Bluesky for this. Everyone stating their issues seems more related to Apple than Bluesky. So why point the finger at them?
I don’t think a significant percent of real Bluesky users actually care.
Having a follow button on the screenshot brings nothing and a logo is helpful when sharing (“hey it’s not twitter, I know it looks like it but it’s bluesky”) and looks subtle.
It’s just it’s a forum so people say things for discussions sake and get outraged by anything that a platform they don’t like is doing.
First - it's great that people can't take screenshots of their sensitive data by accident
Second - I hate when my device keeps me from anything. I'm used to have control over my computer, and this is outrageous that I can't take screenshots of anything I want. There should be a god mode or something like that.
I know of social media sites who have kept an untracked version of the link in the dom of the A tag, but replace it with their in-house link tracker copy of it as you're clicking, that way the destination looks correct when you hover over the link.
A simple call to get a list of sensitive screen areas would suffice. Add a bunch of options to make everybody happy, but don't allow replacement with different content.
This is an interesting case of "Good use" of a "bad feature". This feature is bad because it works against the user and device owner, but this use case like hiding your password when sharing your screen is a good use case.
It feels restrictive, especially since it’s part of a broader pattern of limiting user freedom on platforms. For instance, on PC you can't simply right click on a video and save it on bluesky. They add some frontend bullshit to prevent you from doing that. On "new" Reddit I remember when you saved an image it would always have a watermark on it. On PC, you can't preview the raw image/video either. On Instagram you can't save images at all easily. Cant view content without being logged in, etc.. Now contrast this with platforms like Mastodon where I can do whatever I want with the uploaded media there and there are barely any such restrictions.
Dear app developers: please do not detect screenshots, and do not change behavior. It is my phone and I should have the right to save anything on my screen for my own purposes and you should not know that I do that.
Oh, so you can take screenshots of the content that tries to avoid it if you do it mid-switch?
If it's reliable and WONTFIX, that's almost enough to get me to switch away from Android.
Screenshot taking prevention is harmful and should not have ever been allowed to become a platform-level feature in the first place. Because if there's one rule of platform/client interaction, is that if you add a feature that can be abused against customers for stupid reasons, it will be. There's a number of apps I have on my Android phone that block screenshots for dubious reasons, that can be maaaybe charitably explained by calling them "growth hacking pretending to be a security feature", but in some cases even that's a stretch.
This feature should never have existed in the first place.
(At least Bluesky is open about it, both by being Open Source and calling out the "growth hack" by name in source code.)
Unfortunately way more applications inject some sort of info into the image using noise of alpha channels when you take a screenshot...
Ofc you shouldn't be doing anything wrong, but let's say you join a court and provide some evidence in confidence, you can be found if that evidence is shared with both lawyers
If the feature can sometimes be useful (including this situation, which some other comments mentioned; but also for other things such as hiding actual secure data), then perhaps it should be made as a setting which can be changed in the setting menu (e.g. "Exclude secure data from screenshots"; it should also mention which apps use this feature), so prevent abuse. (This would also make it clear what the feature is, as well as being able to disable it.)
LinkedIn’s job screen in the app is a good example of this different presentation.
I’ve noticed a certain AI recruitment company gets “highlighted” (darkened white background of the screen, but their logo is pure white and REALLY stands out), but when I screenshot it, it reverts to normal, like there’s no blatant special advertising.
Different underlying mechanism. The LinkedIn one (and almost all ads on Instagram/Facebook these days) use a gain map to increase the brightness of the image. Here's a site demoing the tasteful application of this [0], you can see the difference viewing it live versus taking a screenshot of the result.
No because per default the input is not cleared when screenshotting. If you‘d implement this yourself for security reasons you'd most likely blur / overlay the whole screen when the app enters background state.
Probably, but to the extent that was at all a problem to begin with, multiply it by another 0.0001 or whatever for the threat of the screenshot being taken mid switch away!
If not for the function being named "GrowthHack" I would have thought that hiding following status for screenshots to be a good privacy measure. They don't use it to hide anything else and since I'm not a user of the app I don't know if there is more extraneous information that could be used to infer or track down who screenshotted and they don't hide.
Why would someone use Bluesky? Isn't that a cesspool of the same midwit scolds, purity spirals, and performative outrage that made Twitter unbearable before the great migration?
When iPhone shipped, any time you emailed a photo it would append "Sent from my iPhone" to try to virally market. Same or at least similar slimey tactics
This sort of stuff to me is an example of fear within an organization. Whenever I see engineering resources allocated towards self promotion and branding rather than quality and features for its users it shows how leaders want control over narratives.
It's probably silly to make OP's judgement of any of these implementations in isolation, but you can sense a real fear about the growth (or lack thereof) inside Bluesky. Fiddling with the presented metrics (likes count getting moved ahead of reposts), promoting total user signups while being silent on collapsing DAUs. They are promising a lot at once with AI custom feeds from Attie and subreddit-style communities that smells like feature creep.
They aren't my indicators, but they read as sweat against the observable metrics being in decline. There is a perception that they want to pull on users outside of Bluesky that I don't really think exist, and I guess I share in that feeling when I believe the core still has so much basic parity missing with X et al that would demonstrate confidence in the current users you already have. Still interested to see what they ship as.
That's how a modern organization works. You trust your colleagues will do good work, and will ship something useful and there's not really "someone to go through".
I agree this can be defined as cool and very very likely someone did this on their free time/prompted Claude on the side.
It's a Series B company, it needs to make money, and they have to answer to a board and provide information to investors. They have a roadmap, direction, and leadership. Yes, trust and good intentions is an awesome thing and I hope they have that indeed, but I would think reality lies in the middle of both sides.
I've worked at a Series B company and reality is this is too minor for investors to care on its own, and it's also very hard to correlate this change to new revenue, so not something that's likely to have been done with that intention
I agree that having less people to manage means easier to build trust relationships and culture, though I believe some form of management and control must exist.
Marketing, like every other functional part of a business, requires technology and engineers. This has nothing to do with fear, you just don’t respect non-engineering work as critical to running a business.
Someone spending half a day on a feature that places the app's logo in the screenshot so people seeing it can know where it came from is "fear within an organization"? You've got to be kidding lol
Does anyone know a way to do this for a computer? I built a p2ppoker website the protects the shuffle from the server but I would like to blank the cards on screenshots to prevent huds and AIs from making the game unplayable.
That's not what the other commenter is saying. The other commenter is stating that by doing this logo trick, bsky is very similar to competing platforms
Companies always want to slop-spam their logos onto everything. It is a very annoying habit. On youtube videos this is even more annoying; several use floating logos.
The best way to ask for this is to send an email, to the email address which you can find at the bottom of the page (click on "Contact"). There's no guarantee that the mods will find your comment otherwise.
Saying @dang has no effect; it does not activate a batsignal or any other mechanism of mod summoning. The only way to be sure a mod see this is to email them; see the contact link in the footer and include a link to the comment.
Tangentially, I see a lot of people here upset that apps can react to your screenshot before it is captured. I think it is helpful to think about it as a tradeoff between freedoms:
(a) the freedom to screenshot any content on your own device
(b) the freedom to share content with others that cannot be screenshotted
It can be annoying when DRM or privacy features block a screenshot, but I think it can also benefit the platform ecosystem that you participate in as a user too. Idk!
If a type of lock was overwhelmingly used for bad reasons, and only worked when someone didn't cover their hands (analog pictures), I'd be arguing against that type of lock too.
Is it a “bad reason”? Millions of people chose to use Snapchat specifically because of how it handles screenshots. It is a feature even if you don’t like it.
Many people would find it inconvenient to find another device to take a picture with. And that manual picture would then have baked-in evidence that it was taken surreptitiously.
Locks keep honest people honest, as long as the app is up front about it and lets users make the choice, I don’t mind.
Another view of it is that’s just a creative use of the medium. An interactive button doesn’t serve any purpose in the screenshot, so why not find a better use for that space.
When I’m in Safari, taking a screenshot can turn into a totally separate operation (full page scrolling screenshot) and that’s a good feature.
Others complain about Google Maps showing a popup telling the user about location sharing upon screenshot - I think that makes a lot of sense, considering it doesn’t show up in the screenshot and dismisses easily.
I’m very harsh on user hostile choices, in fact I spend a lot of time ranting and raving about it, but I just don’t see that here.
The ability to show exactly what you had on your screen is one of the biggest uses of screenshots. The ability for apps to do this kind of thing breaks that use.
Offering something better can be valuable (sometimes) but don't alter the screenshot itself.
If it's between this and a perpetual logo, I'll take this any day.
I actually really like this approach. The action button isn't relevant in this context, and it doesn't occlude the content.
There's certainly situations where you wouldn't want this (ie if you're developing the app and you want to redesign starting from a screenshot), but for the average user I think this isn't overly hostile. I understand that people are dogmatically opposed to intent being modified, but I think you need to balance nuance. I actually enjoy having an attributable source in shared elements, and I think this is a low-impact way of achieving that.
I actually hate that apps are allowed to blank out content on screenshots, and this can't be disabled. There are apps completely mis-using it, e.g. mobile payment apps which hardly show any sensitive data in most cases, but now I can't share e.g. infos on screen with someone else easily.
It's a classic case of someone discovering a feature and thinking "hell yeah, so much security" without understanding or caring about UX impications.
I've yet to see someone saying "oh, I'm so glad my screenshot was blacked-out because I didn't realize I was in a banking app". It feels patronizing.
> I've yet to see someone saying "oh, I'm so glad my screenshot was blacked-out because I didn't realize I was in a banking app". It feels patronizing.
Yes, this. Payment apps, government apps, IM communications.
The other day I almost rooted my phone in anger trying to get around this, before pausing and realizing that this would only cause even more problems with those apps, thanks to remote attestation "features".
My favorite recent case, I almost locked myself out of mobile government services when changing phones recently[0], and it would've made for a stellar bug report showing when "fail safe" design can easily become "fail deadly"[1], with UI view of access and invalidation history clearly showing the timeline of a problem... if only I could take a screenshot of it. But I can't, because "much sekhurity".
--
[0] - Well, it's not really that big of a deal. With government services, there's always a way back. Might involve walking to a local civil affairs office or, worst case, a police station or a notary, but there is a way back. Big cloud services, on the other hand...
[1] - Invalidating a certificate prior to issuing a new one sounds like a good security idea, but in the real world fails critically if the two operations aren't an atomic group. In my case, issuing a new certificate failed, and I ended up walking around for half a day with old one invalidated and not even knowing it.
On a similar note in terms of frustration, my bank ended up getting me to memorize my randomly-generated passwords twice because it blocked pasting. I guess it's to discourage writing them down in plaintext files, but I bet it just makes most people choose meaningful (and therefore weak and guessable) passwords.
Then they deserve you taking a photo with a second phone
Well, I did, after the fact, but it's only because I had a work phone on me (that doesn't yet actively block sharing to non-work devices).
I doubt most people have a second phone on hand, ready and able to capture actual screen shots when your phone is preventing screenhots.
> much sekhurity
This feeling usually hits me at airports, with my shoes off and water confiscated. The terrorists won.
We're heading for two devices, IMO. A useful one and one for communicating with bureaucracies.
Software that intentionally subverts the intent of the user is malware. We now live in a world where most financial institutions literally ship malware as their primary or only interference to access their systems.
I understand the sentiment, but think about the non-technical user. Every time I use my mothers or any elderlies phone there are a lot of screenshots in the gallery, because they accidentally click the combo. How many people get scammed using screen sharing? It isn't that unreasonable to prevent this vector just to be more safe, especially if the bank might be partially at fault if a scam happens.
People also take pictures of their government IDs (passports, drivers license, etc) and utility bills.
Should the phone identify those things and automatically blur out all of the sensitive information in those photos too?
I’d prefer if my phone did neither that nor told the apps that a screenshot was being taken nor allowing the apps to hide anything that was on screen when a screenshot is taken.
It’s my phone, I want to decide what I take photos and screenshots of.
> especially if the bank might be partially at fault if a scam happens
That's the crux.
Yes, it is unreasonable, because scams have proven to be just as effective at getting people to just read the details out over the phone line, and bank these days are not showing much sensitive information in the open anyways (my recent annoyance - someone thought it's a good idea to never show the full account number on screen, showing just first and last few digits, and an option to copy to clipboard...).
Meanwhile, those very apps tend to be ones people would most often want to screenshot for legitimate reasons - e.g. to communicate or make a record of specific transactions, accounts, their states, metadata, etc. None of which is copyable text in the app, and most of it isn't even properly exportable, so it's not like there's any other way.
This just reinforces the notion that apple is the one that actually owns the phone and they generously let you use it.
Just do a security alert pop up "You are screenshotting potentially sensitive information, are you sure you want to continue".
Unfortunately “are you sure?” checks simply don't work, too many people are trained to just click yes/OK to close the message and get back to what they were trying to do.
Hoping to not sound like a broken record, this is why having full ownership of your device and OS is important. My stock Pixel Android recently told me something along the line of "A security policy blocks screenshots for this app. Talk to your administrator if you want to change the policy". I looked in the mirror and my administrator said "time for a policy change, we're moving to GrapheneOS".
And just as important: Help your friends and family to move as well, so they can have ad blockers, NewPipe etc. We need a critical mass of users invested in their freedom, otherwise its going to be crushed by malicious/dumb security measures of their banking apps, corporate greed ("oh, a simple misunderstanding, when you clicked 'buy' you rented a limited license. Did you not read the ToS?") and police overreach. It's a perpetual battle.
“Security” that makes ordinary sharing unusable is often just UX debt wearing a security badge. The right fix is selective redaction, not disabling screenshots everywhere.
> “Security” that makes ordinary sharing unusable is often just UX debt wearing a security badge.
Very true.
> The right fix is selective redaction, not disabling screenshots everywhere.
That's still a partial fix, though. It would address the problem of accidental screenshots in a better way, but the main point of contention is around intentional ones. Here, the problem is that the app vendor and the user have different notion of what is "sensitive".
I went to screenshot my upcoming Verizon Fios fiber install out of excitement and got an immediate warning dialog.
WARNING: You are in violation of the My Fios app end user licensing agreement that prohibits duplication of this screen. Please immediately delete this from your device.
... apparently buried in the app T&Cs is a "Distribution of the technician's picture or information is prohibited". Even if there's no tech assigned, the screen with the picture of the grey fake man with a fake hat apparently causes a big old warning if you screenshot it.
It is strange how this spawned a 100+ comments discussion on HN.
It's not about the logo. It's about abusing a platform feature that arguably shouldn't exist in the first place.
This is phone OS developer's fault for even allowing it. When I take a screenshot, I expect to have an image of exactly whatever was displayed on the screen at the time. Its not a picture of your app, its a picture of my screen. Some banking apps used to (or still) prevent this and now some apps get a hook to insert their branding. My device serves some master other than myself.
This exists for a very good reason.
It’s so if an app is showing a password or bank account number or other piece of sensitive information it doesn’t accidentally end up in a screenshot. I think there are other places sensitive information won’t show.
Bluesky, and apparently others, are abusing the functionality for advertising purposes.
I think it’s a good thing it’s there. This functionality should be easy for apps.
I’d say this is one for app review or an App Store rule. But we all know those are a total joke.
I don't have an issue with BSky's use, but I regularly run into the functionality's abuse elsewhere, such as multiple of the biggest Thai banks' apps where every screen in the app entirely blocks screenshots (iOS). Doing a P2P money transfer and want to send a screenshot to the recipient for them to confirm their info before you hit submit on a non-reversible transfer? Blocked. Want to screenshot a promotion's terms for proof or a personal reminder? Blocked. It's even worse as multiple of the biggest brick-and-mortar Thai banks wholly dropped web access and are now smartphone-only. (Or more obscure, want to translate a single-language screen into another language? Blocked.) Etc.
>Doing a P2P money transfer and want to send a screenshot to the recipient for them to confirm their info before you hit submit on a non-reversible transfer?
Why not ask contact for data via text and just copy paste it with double check?
What if the app doesn't allow pasting? What if the communications app prevents copying?
For a short while, screenshots were a workaround for blocked copy-paste[0], as OCR (and, more recently, edge-deployed vision-enabled language models) would allow you to copy and paste any text from a screenshot. But guess what, now every other app is blocking screenshots!
--
[0] - Which is the default on mobile apps, and unfortunately desktop apps too. I hate webshit applications, but if they have one redeeming grace, it's that by default, all text can be selected and copied, and it takes nontrivial engineering effort to break that, so most webapp vendors don't bother.
1. On the pre-submit-button screen it shows the recipient's name to confirm, but as in the GP example, if the recipient's name is in a character set different than your own, it would be nice to be able to have someone who can confirm the recipient's name matches.
2. And even if you copy-paste the recipient's account number, that also relies on your counterparty not having mistyped their account number, so it would be nice for #1 to be possible to confirm the name.
I want to take a screen shot of the transaction I just did. Can't because some ahole decided for me that it's too sensitive information and blacks out the whole screen. this API is stupid without control in settings of the os
Yeah, I used to have this issue a lot. If I use my personal card for a business expense, I used to like to keep a screenshot of the transaction on the card as well as the invoice. As it's an app-only challenger bank, this is the only way short of exporting transactions as a PDF and that includes other transactions for the day. For a long time I used to use another phone to take a photo of my phone screen. Eventually, I just stopped bothering taking that photo because of the extra hassle, but it never stopped annoying me that I couldn't keep the records I wanted easily.
Yeah, I would rather see a warning in that case that the screenshot could contain sensitive information, with options to take a redacted screenshot or a normal one.
Lots of people here exposing their single sign on approve code because a scammer ask them to send them a screenshot.
I mean... "please read me the code you get via text" or "this really Bank of America, please type your OTP" seems to work well enough. We really don't need OS-level controls for stuff on the screen. People can just tell you what's on the screen.
So that means this change will result in a noticeable decline in such scams, right?
Right??
you don't have a share button tha generates a PDF and shares it with whomever?
Often, you don't, because the same developers of the bank app decided it's an unnecessary power user feature that doesn't fit in the MVP or something.
Or, even if they add it, there's no way to save the file, only to "share" it, which 99% of the times isn't what I want, and I'm frankly tired of routing through the mail app as a workaround. At this point, at least on Android side, there exist apps whose sole purpose is to be a share target and dump the information to file (and being apps on an app store, chances are top 10 are just thinly veiled malware).
really? I'm not suprised by shitty developers developing shitty apps but i'm still baffled. Surely the bank would be getting tons of angry emails from customers if it happened in europe
Would they care?
They probably support proper export for business accounts. Business customers have leverage. Regular people? They're an annoying but necessary nuisance.
>This exists for a very good reason.
This exists for a very bad reason.
>It’s so if an app is showing a password or bank account number or other piece of sensitive information it doesn’t accidentally end up in a screenshot.
and also coincidentally if the app is showing something incorrect that you want to be able to verify and provide proof of now you can't.
>I think it’s a good thing it’s there. This functionality should be easy for apps.
I think it's a bad thing it's there. The functionality should be easy for me.
OTOH, I might very well want to take a screenshot of my own bank details, transactions, or other sensitive information. It's annoying that my information is being protected from myself.
You might have amazing operational security but lots of other people don't, and they make noise, which means governments write laws meaning that banks have to refund them for fraud.
So as much as a bank might agree with your stance on freedom of compute - they probably don't want to pay for it with actual money.
Banks have managed to externalize the costs of their own security onto people by inventing the concept of "identity theft", and pinning the blame for poor security practices on regular people.
They really shouldn't be allowed to double down on it.
And arguably, half of it isn't even really security, it's about keeping you in their app. Application interface is the ultimate sales platform, and banks are making extensive use of that fact.
Then it's a bad solution to a real problem. A better solution would be exposing a hook that apps can call when a screenshot is initiated that tells the OS to warn the user before saving the screenshot. This way the user is actually educated on the risk while still respecting their right to control the outcome.
The OS could draw an ugly censoring block over the sensitive information. That would protect the user's privacy when needed but also prevent apps mis-using the feature like this.
It could. But the root problem is, there is no such thing as unqualified "sensitive information". The information is sensitive to someone, for some reason. The problem with screenshots manifests when the app and the user disagrees about whether the information is sensitive and who has the right to control it.
The immediate technical problem is that OSes allow apps to declare what is "sensitive", and then follow those declarations unquestionably, preventing any preservation of that information.
The underlying social / political problem is that platform vendors allow app vendors to unilaterally declare what is and isn't sensitive, and proxy their opinion without question, and with no consideration for users and their context.
I don't think Apple cares about apps replacing the follow button with an icon. It's a weird use of the api, but it's not abusing the user or a security/privacy risk.
Yeah. I wonder if Apple does something to change this.
This is a failure of imagination for Apple, but it’s hard to blame them.
Who would think someone would put a button inside a “secure” text field and change the masked appearance to a logo?
If I was proposing this feature, I would never imagine someone would come up with something like that.
It's MY phone that I paid over $1000 for. Let me choose what is exposed and what is not.
This shows hardware won't be yours unless the software running on it is open source. Asking a company to modify its closed source software might work occasionally, but it's a band-aid and a never-ending battle.
> it doesn’t accidentally end up in a screenshot
Your banking app probably has an option to disable that because it's a legal requirement in so many places: People who can't see need to use assistive tools, and that includes screenshots and friends. If you are using a tiny/stupid bank in the US, file a ADA claim and get some money. In the EU check your Ombudsman.
No, it's so you can't screen-record Netflix. The bank doesn't care about that because it's not a liability issue to them, just fetishism; no way they pay Apple and Google for this capability.
Apple and Google should step in and allow users to remove these shenanigans with a little button on the screenshot preview screen, but resist this because of Netflix et al.
I don't think they're abusing functionality at all. I don't think screenshotting a skeet should, by default, leak the follow state of the user taking the screenshot, which is what would happen without the secure input swap
"Secure inputs" take many forms, and it doesn't feel like this is abuse in any meaningful way
One person's "sensitive input" is another's "key information".
Follow state is a useful bit of information. There's argument to be made for both hiding and preserving it.
"accidentally end up in a screenshot" --- how often do you even take a screenshot on a phone, much less accidentally?
Almost daily on my iPhone.
The side button (https://support.apple.com/en-gb/guide/iphone/iph7d116e557/io...) is on the exact opposite of the volume up button. Pressing the side button to shut down and lock the screen is something I do a lot. Press button (2) with the thumb and you will see that it is very natural to have your index or middle finger resting where the volume buttons are.
And occasionally I press hard enough with my thumb that the finger on the perpendicular side of the phone presses the volume up button and whoops I have taken a screen shot instead.
That said. I do consider this "feature" an abuse of privacy API:s, and I also often get annoyed that I cannot take screen shots of my bank app to for example send account information, or confirm a transaction, or report a graphical bug to the developers at the bank.
Consider that people use their phones differently than you. I take screenshots on a daily basis, accidental ones at least once a week. Usually it's just the lock screen though.
https://www.reddit.com/r/iphone/comments/ykm933/how_often_do...
I take them constantly. Not even sure how. I think it means I am “of a certain age” these days.
Now get off my lawn.
i take many screenshots, but about half of them are accidental (somehow it recognizes the "tap three times" gesture whenever it feels about it)
Account numbers appear on checks. They are not exactly secret, and if I want to take a screenshot of one, I should be able to.
But how can I take a screenshot that intentionally shows the password or whatever?
Use a device with an operating system that doesn't think it knows better than you what you want.
You're not that unlikely to leave that feature in place if you have such an operating system. What you really want is two controls: one for "safe screenshot", and another for "raw screenshot".
If it's to prevent accidents, it should just prompt user to confirm saving the screenshot with sensitive information.
As it is, it is just an annoyance that requires you to do stupid workarounds like taking a photo of your screen.
Imagine if a password manager didn't allow you to copy the password since you might accidentally paste it somewhere incorrect.
Funny enough, that's what the big passkey folks want: https://github.com/keepassxreboot/keepassxc/issues/10407
Really glad open-source password managers are resisting the bullying and not implementing DRM.
For now: https://github.com/keepassxreboot/keepassxc/issues/10406
Or not: https://github.com/Kunzisoft/KeePassDX/issues/2321
They are imo clearly gearing up to lock down passkeys in practice one day so that you will only be able to use those tied to a Google or Apple account (or some new player). They're already threatening in these issues to blacklist open implementations that don't submit to their requirements, and then requiring an attested client would then become the "best practice" adopted blindly and widely. I think the only hope is for the open clients to fully submit, hoping to avoid full attestation, while not making it too hard to patch out the anti-features. Of course, anyone who can't compile is screwed though.
> Imagine if a password manager didn't allow you to copy the password since you might accidentally paste it somewhere incorrect.
... have you heard of passkeys?
Yes, it's as stupid as it sounds. And works about as well.
If a dev forgot to obfuscate the password and rendered it as plain text on the screen, then what are the chances they remember to program the blur into this screenshot api hook. Or why not add an alert, “what me to blur sensitive info? Yes/No”
Unfortunately there's platform-level features for marking surfaces as sensitive/secure. So your dev would typically just mark the whole app as such, and be proud of their proactive problem solving.
I can always just pull out my second phone to bypass all this shit.
Which is why everyone should root the their phone to turn this kind of shit off.
1000%. Apps should not even be able to know that I've taken a screenshot - let alone change the contents of it.
The app doesn't know. It just produces a widget tree, and the OS-provided renderer renders it this way or that way. In particular, it chooses not to render controls marked as "security-sensitive" when the rendering is intended for a screenshot; it could instead put empty boxes in their place, etc. The app has no idea and no control, AFAIK.
Even having never developed on iOS before, I was able to find this in the first google search result for "ios api to detect screenshot": https://developer.apple.com/documentation/uikit/uiapplicatio...
Open the amazon app. Take a screenshot. See a toast message informing you that the amazon app has detected you've taken a screenshot. Fucking used for fucking profiling.
Don't apps like Snapchat notify the other person if you take a screenshot of your messages?
Yes, iOS has userDidTakeScreenshotNotification for that.
https://developer.apple.com/documentation/uikit/uiapplicatio...
Would be nice if the user could disable that.
Yes, Snapchat does this. Apps absolutely have the ability to know when a screenshot is taken.
Snapchat advertises that they detect screenshots. They try. But they're well aware that they can't actually know.
For example, their bug bounty program policy helpfully informs you that "screenshot detection avoidance" is not considered a vulnerability: https://hackerone.com/snapchat . That's because it's always possible.
The apps definitely know. Horsemen example: If you screenshot on Amazon (and Business version) iOS apps, it “helpfully” pops its own share sheet.
I wonder if this is the expectation of the majority or just the expectation of us tech people.
Because I assume most people want to take a screenshot because they want to capture something they are seeing in the app, most people probably are even annoyed to have the system indicators visible there.
Bank apps black out the whole screen when I take a screenshot and it’s super annoying. As a user, I should be able to take a screenshot of my screen. I can use a camera or another phone to do it anyway.
iOS allows something similar. twitter (X) will also add a logo. I believe reddit did the same but i stopped using their app a while ago.
Reddit has a toggle in its settings to disable it. X, too, I think.
Personally, I wish iOS didn't even facilitate this.
edit: to be clear, I don't think iOS should notify the app at all. The app could register areas as "invisible to screenshots" perhaps - I'm torn on that functionality.
That's what bluesky is doing in this case. It is showing the button on an area that is "invisible to screenshots", and the butterfly is behind it, so it shows through when a screenshot is taken
iOS allows something similar because this is iOS. iOS allows something exactly the same because this article is about iOS.
Bluesky trick exposes how strange the abstraction is
So...
> and now some apps get a hook to insert their branding.
No, apps can already insert their branding anywhere they want. They're writing the app. If they want their logo to be visible in screenshots, they have infinite ways to do that.
This particular way seems basically prosocial. It's much more useful to me as a consumer of the screenshot to see that it came from Bluesky than to see that there was a "Follow" button. It's not what the feature they're using was intended for, but I can't call it an abuse of the feature. What they're actually doing is good.
The fact that you're getting unexpected behavior isn't good. Sometimes you want to create a picture of sensitive information. You should be able to override the app developer's security settings.
The thing that really irritates me about the banking apps blocking screenshots is that it's pretty clear to me it's not about protecting customers but denying customers the ability to document something related to their account.
No, it's about saving the bank money - and what costs them a lot of money is the average person being fooled into sending people their account information easily.
But every bank app which I used had a button to copy all of those directly.
if only there was some kind of app review process... but Apple doesn't care.
I guess the Bluesky bros got inspired by Threads, again.
> I expect to have an image of exactly whatever was displayed on the screen at the time
Do you/should you (we) really expect that though? I regularly use color filters on my apple devices— grayscale to avoid distractions during the day and red tint at night. More recently I’ve been using the motion dots. I don’t know that I can say with confidence that I never want any of those “personal-perceptional-modifiers” to appear in a screenshot, but for most folks, I would guess it’s approximately never.
I want those things included, at least by default. A screenshot normally captures the user’s screen size, brightness, zoom level, font choices, etc.
It is often important to people that the screenshot is an accurate record of what was on the screen.
It doesn’t copy the brightness AFAIK
The effects of cramming 2 separate workflows and 5 features into one thing called "screenshot" because anything else would end up with something too complicated for users to understand the interaction (sarcasm that figuring out what the behavior is locked to in these scenarios is just as confusing).
While we're at it, this "share" containing the copy/paste flow is the exact same kind of thing. And screw whatever logic decides to copy the URL of an image instead of the actual image sometimes from Safari when I select to copy it!
And whatever’s worse than screw for copying presumable pngs as .webp or whatever that format is
This is in fact a watermark to promote the application, which otherwise wouldn't be recognizable since Bluesky looks like every other microblogging app. I didn't know that Sam literally named the file GrowthHack.tsx, which is pretty funny.
> which otherwise wouldn't be recognizable since Bluesky looks like every other microblogging app.
The text at the top of the screenshot is
> Eric Roston
> @eroston.bsky.social
So it's pretty easy to tell IMHO.
what happens when it’s a custom handle like @example.com?
Honestly I didn't know that was a possibility. In that case yes, it's probably harder in when that's in play.
I can't help but respect the dev's self-awareness
I mean, X does the exact same thing
Well, I have not once found a single case where an app reacting to screenshots and controlling the process in any way was anything to me but hostile and annoying. This one does not help.
It somehow is perfect example of how modern software engineering feels to go astray for me. A feature in my device working completely in benefit of the one providing said software. I wish, and wish only I can, that this trend goes away at some point.
It is actually astonishing to me that this is not something which can be turned off at the OS level, or as a permission setting in the app permissions.
The app knowing I took a screenshot feels adjacent to me to a keylogger. Imagine how many apps are capturing that information silently. To my mind, a screenshot is something that is happening outside of the app context, the app knowing about it is a security flaw imo.
> The app knowing I took a screenshot feels adjacent to me to a keylogger.
To my knowledge, this is a misunderstanding. The app does not know that you are taking a screenshot, rather iOS knows you are taking a screenshot (as it must) and is excluding an element on display that has been designated by the developer as sensitive information. This is the same technology that prevents you from accidentally screenshotting your password manager; the developer has simply performed a nifty trick to display a small icon behind where the “follow” button would otherwise be displayed.
There are plenty of instances where this sort of thing can be annoying, such as when you try to screenshot a streaming service app and DRM enforcement leaves you with a blank screenshot, but IMO this particular instance is actually very tasteful; seeing “follow” on every screenshotted post is just useless noise, but a small unobtrusive platform icon is a useful reminder that the post came from Bluesky and not another very visually similar service like X(cancel) or Mastodon.
The app actually is notified after the screenshot is taken: https://developer.apple.com/documentation/uikit/uiapplicatio...
Android does it too: https://developer.android.com/about/versions/14/features/scr...
This prevents us from taking scrolling screenshots (a native feature in many smartphones today that is often useful when there is more than one screen of content).
I dislike this hijacking for that reason and wish there was a way to turn it off.
Spotify uses this and it annoys me all the time.
If you screenshot what you are listening to, after the screenshot is taken spotify will open a full-screen popup to "share" the song you are listening to. This is quite dumb, especially since if you wanted to share a song via the screenshot, you can do so in the OS-level screenshot UI, and then you would close it and see Spotify's own similar version of the same UI. Spotify just really wants you to use their own share button so that they can track you.
I’ve seen another app do that but for a different reason. It’s for security cameras and they use it to show a “hey idiot just press the save a picture button, don’t take screenshots” popup, which is also hostile.
I’m not sure why the app needs to be notified. There must be some use but I can’t think of it off the top of my head.
> I’m not sure why the app needs to be notified. There must be some use but I can’t think of it off the top of my head.
My pet theory: it's because Snapchat got big early, platforms added the feature to facilitate Snapchat's business model, and then banks started abusing it, and it stuck around "because sekhurity".
Yeah it’s Snapchat. If you take a screenshot of a (potentially extremely private, intended to be ephemeral) image, it notifies the person who sent it.
Anyone can take a "snap" of the phone screen with another phone's camera so this is a losing battle anyway.
It amuses me that browsers in incognito mode refuse to allow screenshots on mobile. But same browser running incognito on a desktop can be merrily screenshotted. What is the difference they are trying to enforce based purely on device form factor/OS.
Yes, it is very annoying. But I think they are already tracking you.
They want use to use the share button so your recipient is more likely to open Spotify (or whatever app) themselves.
Very interesting! Parent poster is correct, that notification does feel akin to a key logger… although I’m not sure that it applies to this bluesky feature.
So in this instance, am I right in understanding that iOS posts a notification after the user has completed a screenshot, which would make it impossible for the developer to use this notification to trigger anything that would modify that screenshot? Hence the developer’s work around?
Correct.
Though I don’t see how this is anything like a keylogger.
> This is the same technology that prevents you from accidentally screenshotting your password manager
Yes, and I would say it's a bad thing that the OS tries to prevent this.
> seeing “follow” on every screenshotted post is just useless noise, but a small unobtrusive platform icon is a useful reminder that the post came from Bluesky and not another very visually similar service like X(cancel) or Mastodon.
I would say it's a bad thing that Bluesky makes the screenshot look different from what was on screen for the user. If I cared about excluding the "useless noise" from a faithful depiction of the pixels on my screen, I could address that myself.
Why is this feature bad?
As someone who develops apps for confidential conversations, making it harder for people to screenshot the confidential stuff is a feature the sending party wants, that is why they send in your app as opposed to others. It doesn’t make things impossible, just hard enough that 95% of people won’t bother to take a copy.
Same for example with disappearing audio messages on whatsapp
What I don’t like is the app being informed that I took a screenshot. The OS can hide things in screenshots without this.
One user wants it not to be shared, but the other user might have various reasons to want to take that screenshot - maybe it's evidence of something they need to share urgently with others, whatever. It's definitely hostile to that other user. I get why you'd set it up that way, but it's a tension that really goes against the "full control of your own device" ideal a lot of people have.
Don't send me anything you don't want screenshotted. Easy-peasy. I'll accept an opt-out of whatever protections are in place for the general user, but I don't accept that those protections should remain in place for all users. It's hostile.
Honestly, even schoolkids know to have another phone/camera(usually a friends) take a picture of their phone screen.
In a world where people have multiple old phones lying around it isn't that hard to come up with this workaround.
If you send it, it is no longer yours to control.
If it is my phone, it should be mine to control. Too often it really isn't my phone...
It's mostly dumb because of obvious analog loop holes. I at minimum carry 4 devices with cameras, often as many as 12. If I want to capture the disappearing message... I will do it; making it annoying just makes me pissed at the developer + the is.
> Yes, and I would say it's a bad thing that the OS tries to prevent this.
Another way to look at it is the OS makes certain guarantees to the developer around security. Giving control of this to the user would erode that guarantee from the OS to the developer. The result of that is that some developers would simply never display some information (e.g. due to their own contracts or reasonable concerns about fraud/abuse/etc.).
Very similar to the video pipelines in modern devices. Prior to video pipelines which the OS could attest could not be hijacked by the user, many content providers simply would not allow e.g. Netflix to release their content on certain platforms. That the OS does provide such an attestation option for developers allows uses that otherwise would not exist.
But… but they allowed. For a long time. Netflix didn’t need that.
"The app does not know that you are taking a screenshot, rather iOS knows you are taking a screenshot (as it must) and is excluding an element on display that has been designated by the developer as sensitive information. This is the same technology that prevents you from accidentally screenshotting your password manager"
And that is reasonable, but it is also a surface where an app touches the OS, which should be a permission boundary that I can control. Allowing the option to opt-out of screenshot blocking with a proper double-confirm warning and biometric auth is also reasonable.
The OS notifies the app after the screenshot is taken. The app doesn’t get to do anything in response to it being taken or allow it to be blocked.
They’re abusing an iOS text rendering control function handled by the OS. Before the screenshot is taken iOS swapped out the rendered text for “sensitive” fields and images that.
The replacement is supposed to be something like a masked account number, password asterisks, or just general blur.
Not a marketing logo.
It's wrong. iOS sends an event on screenshot.
https://developer.apple.com/documentation/uikit/uiapplicatio...
> This is the same technology that prevents you from accidentally screenshotting your password manager
I should be able to screenshot anything I want, including my password manager. I should be able to opt-out at the OS level, or any other level that enforces it. That's why it's definitely a user hostile feature.
Neither of those use cases seem good or tasteful to me as a user, I don't think this concept of "secure (from the user) context" should exist, but maybe that's just me
Can Snapchat no longer inform the other user when a screenshot was taken?
can someone just take a picture of the phone with another phone, or use a screen recorder?
Security is never absolute, it always "merely" raises barriers.
lol. downvoting on this is quite dumb.
pretty sure i was pointing out it is best not to think you are safe sending a message without considering the fact that people do these things.
RIP rational.
mmm on average we’ve probably considered the photograph of a screen, and we were focused on:
>To my knowledge, this is a misunderstanding.
re: an OS informing an app of a user action (but didn’t downvote ya)
the other device then likely indexes it after a brief once-over by its own ai-enabled os. any crossover interactions, and it may as well be the same device. maybe some of you have not experimented enough with the theshold to have noticed yet.
Able to elaborate for me?
I think bsky's use of this malware feature is as benign as it's possible to get, but it's still a malware feature. As you point out, the real reason this exists is to enforce DRM and make your computer serve Netflix et al rather than the person who owns it.
> accidentally screenshotting your password manager;
I could not think of a more useless justification for installing malware into the OS. Okay, you've accidentally screenshotted your password manager. So what? Are you going to accidentally upload it to the internet too? I'd much rather live in a world where people who are that stupid face minor consequences for their actions than one in which all of our own computers are used against us.
As with most things, it would be ideal if we could have both good defaults to make things accessible and advanced user controls to allow users to retain control. That’s a rare mix these days.
People like to say that. How many hundreds of additional options would a modern phone OS need to provide that though? How could applications possibly be tested? You could have a million installs and 300,000 of them could easily have fully unique combinations of options past what’s available today.
How could you ever provide support to a user? “First take 200 screenshots and send those to me…”
> The app knowing I took a screenshot feels adjacent to me to a keylogger.
That is what this article is about and why you should read it before commenting. The whole point is that it doesn't need to know you're taking screenshots. That's why it's a clever trick.
But for completeness, iOS apps can detect screenshots. That’s what allows them to show annoying popups with a share option when you take a screenshot.
What? App-B on iOS knows when I'm taking a screenshot from App-Y? I don't have iOS to check but that seems crazy.
No, I was talking about App Y knowing about a screenshot you take of App Y.
Isn’t that what everyone is talking about?
Yes, that commenter is lost.
I guess it would need permissions, but you can monitor the photo library with PHPhotoLibraryChangeObserver and check if a new item's subtype is photoScreenshot.
Otherwise userDidTakeScreenshotNotification only fires for your own app
Yes, as does android.
https://developer.apple.com/documentation/uikit/uiapplicatio...
but you didn't read the part where the mechanism is explained? it doesn't do anything like capturing information. it just marks a button "sensitive" causing it to be hidden in a screenshot, thus revealing an icon that was put there underneath the button.
Did you read the article? Bluesky doesn't know you're taking a screenshot, iOS just hides the follow button in the screenshot (consequently making the Bluesky logo visible).
iOS does tell the app that a screenshot was taken though

> hostile and annoying
If someone from Google Maps or LinkedIn team is here, please, when I take a screenshot it's because I want to a screenshot, not share the friggin location/post.
Not sure who got the idea that it was useful, it isn't.
I would happily use the Google Maps "share" feature, but I've yet to encounter any but the simplest of scenarios where it actually preserves the entire context of what I'm trying to share: the viewport, the start and destination, stops along the way, route choice, the time of day, all of it.
If I'm sending a screenshot it's because I want to send exactly what I see on my screen and not have my recipient's gmaps instance happily recompute a route it thinks is better or leave out the routing information I included, or switch from biking to driving directions, or whatever else.
It's of course about lock-in. In the early Web-GIS era there were a few competing but popular notation standards for sharing lat/lon/zoom/<sometimes more> that was meant to be human readable and compatible with any WMS or similar.
Ah... to imagine a world where you could just share a coordinate string and people could open it in whatever map app/page they wanted. Geo URI is probably the closest we have today but I don't think much of anything outside the OS Geo community accepts it.
I think that's actually a separate issue. What I specifically want from a Google Maps share URL is for it to be something I can send over text that will reproduce for my recipient exactly what I see.
A lat/lon/zoom/start?/dest? is kind of what a Google Maps share currently is, but it's neither an interoperable standard nor a reliable capture of the current state, so really the worst of both worlds.
(Also, hi AB! Nice to see you on here)
Hi! I think I’m on the same page (give or take a zoom level) now. That is hard to do between separate geodatabases (hence CRS, placenames, geocoding, etc.) but Google isn’t even doing it within their own. And the only way I can obtain a link is to first place a pin, which wants to snap to nearby features. If I try to link a nice trail near my home it snaps to the quarry instead, making me look like a maniac with a terrible idea of what a “quiet walk” looks like.
I've noticed similar things with off-road biking as well. Hydrocut generally does an okay job of snapping to the trails there since Google knows about them, but I was at Rondeau this weekend, and Google kept insisting I was on the adjacent Lakeshore Rd rather than the Harrison trail [1] that I was actually on. And this had real consequences because my youngest and I had become separated from the rest of our group and were trying to use a "share my location" through Signal, but the Android system-supplied location used was the one that had been unhelpfully snapped to the road.
[1]: https://www.alltrails.com/trail/canada/ontario/harrison-trai...
The other reason someone might want a screenshot specifically isn't to share a location, but to share a route. For instance, I might want to text a friend a screenshot of my driving route. Maps can sometimes route weirdly, so this is definitely a use-case I've needed before.
Google does provide an interoperable standard for communicating lat/lng pairs via text: https://maps.google.com/pluscodes/
I believe it was their response to what3words. It's not as good at the "communicating by text" use case as what3words.
I have a seething hatred for google maps links people send on mobile because Google no longer shows you the map in your mobile browser. It has for at least a year or twoo required Google Maps be installed to show you what the person linked to.
It's not about what you want. It's about increasing engagement with the Google platform
Today I noticed that Amazon Pharmacy decided to blank out my prescription info that I was screenshotting to send to my doctor. WTF.
From the same lunacy that forces me to write my 30-something character Wi-Fi password on a "secure password field" that only shows me the last character, almost ensuring that I will make an unlimited number of typos and spend way too much time for something that should only take 30 seconds.
It's not clear who it is protecting against, it does not seem to be effective at protecting against anything at all, it is actively annoying to the user, and has no way to disable. Perfect example of the usual "security theater" feature.
That seems oddly user hostile for apple. Especially for Wi-Fi passwords, which are a very common thing to share. Android has had a feature for years that generates the password as a plaintext-encoded QR code so you can share a wifi password without the other party even needing to type it in. And at least on my pixel 9, I have a toggle on the password entry field to toggle visibility.
I don't have an iOS device handy to compare against, but it surprises me that Apple wouldn't also recognize that Wi-Fi passwords in particular are extremely common things to share.
Super secure!!1one
Unsecure: open Shortcuts, tap Gallery, search “Adjust Clipboard”. Add to Action Button folder and run from Action Button. - Or add “Dismiss Siri and Continue” action after “Get Clipboard” so you can say “Siri, Adjust Clipboard”.
Type in the still-unreasonably small window, tap Done, paste password. (Then clear clipboard I suppose and consider privacy implication if your clipboard syncs to Mac.)
.
Was referring to the other point.
Could write my own phone operating system to not be subject to the iOS WiFi password field display settings though!
.
Just need some help mining the ore to make sure it’s conflict free (OK would actually really like that if it were possible!)
Apple gave too much power to iOS developers. They can use DRM strong enough that when your iPhone is open in iPhone Mirroring on your Mac, and you record your Mac screen with a third-party tool, the iPhone screen is blacked out.
And if you take a screenshot of a product in the Amazon app it hijacks that and copies a link instead.
I bet this is the inverse problem. Someone thought "oh a prescription is definitely privacy sensitive information, I should ensure the OS does the right thing" not realizing this counter productive behavior.
Yeah, health information is interesting in general because it needs to be kept strictly secret from unauthorized people, but people also often need or want to share their own information and have every legal and moral right to do so.
Blame Apple for even allowing apps to be aware of the user taking a screenshot.
Just like their iCloud Keychain API that lets apps secretly track users across app reinstalls and device resets.
Getting your account back on reinstall is good
That's what a username and password are for. I'd rather not be forcibly tracked.
I have 200+ different passwords stored in iCloud Keychain, each 20+ characters long. How am I supposed to remember all of those?
Do you use the same password on every site? How do you deal with data breaches?
Major reason I don't use password managers that much.
> Do you use the same password on every site?
I use a password I can reconstruct in memory for sites I care about logging in by hand. If I don't, or don't mind resetting my password each time, I just use random garbage + whatever platform password manager is the one active today, with vague hopes that it'll still be there the next time I need to log in.
> How do you deal with data breaches?
Who ever cares about those? I'm yet to hear about anything impactful being released on those. It only matters if you actually do reuse the same e-mail/login and password combinations on both important sites and garbage sites. Which is something you should not. But 2FA and magic links tend to solve that vendor-side, these days.
You can just use your own password manager and it wouldn't automatically do anything to apps on reinstall, right? Or a physical notebook, maybe.
I’d love to have my own password manager that syncs between all my devices without relying on a third party server, but I don’t know of one. Do you?
A physical notebook is so easily lost I wouldn’t even consider it.
I use KeepassXC and Syncthing. It's not a single password manager doing both the managing and syncing, but it works very well, and I sync between phone/laptop/desktop without any third parties.
Do they work on iOS?
Keepass database is an openly documented format, and there are several apps available on iOS that use it and can store the database in your iCloud (ie syncthing is not required, unless you need to sync to non-iOS devices)
Just search for keepass in the app store (Keepassium, KeePass Touch, Strongbox, ...)
Great name.
Frank Dux was a fraud! :)
It's massively confusing to users though.
Maybe, so long as it's optional.
I can fucking type my username and password, thank you.
And I prefer to see and choose the data an app stores on my fucking ICLOUD ACCOUNT. And fucking DELETE it when I want.
There's no way to do that from an iOS device.
.
I thought your other comments about writing your own were sarcasm about how that's such a terrible situation if that's the kind of thing it would take.
But this one looks like you actually mean it? Yikes.
Someone should follow you around saying that to you every time you complain about anything
How else are they gonna track you? Think of the big tech
Good thing if you have GMaps open to the directions list while driving and tell Siri to take a screenshot, it doesn’t throw up a full page of nonsense over your directions that only Voice Control (not Siri alone) or a [potentially nonexistent] passenger could close.
Oh wait it absolutely does.
It still baffles me that it has become normal for an OS to place the wishes of an app above those of the user.
Hijacking the screenshot process is a privilege that you ought to be able to revoke, it's insane to allow software to be given more control.
And don't tell me it's anything to do with security when it can be circumvented in any number of ways.
> Hijacking the screenshot process is a privilege that you ought to be able to revoke, it's insane to allow software to be given more control.
It should not exist as a control in the first place.
I know it may sound absolutist, but the way I see it: if you allow this as a user-revocable permission, then the very apps that need to be screenshotted by users most often will be the first to refuse to work at all unless you grant this permission.
Screenshotting is an system operations level feature. Apps should be neither aware of, nor able to interfere with, a screen capture being taken.
Did you read the post? Nothing is hijacked, but its a trick where they render the normal button in a ui element for secret data, which is blanked by the system on screenshot, revealing the logo underneath. Its a reasonable feature, so its hard for apple to control it better or remove this.
That is a lot of words just to make it sound reasonable that a page can be exempt from the underlying screenshot functionality. It isn't. Not without asking the user.
users should have some way to control if screenshots have secret data in them or not, really. what if I do actually need to preserve it?
I like your idea. When the screenshot is taken a user can have an option: Include Secrets? And the Apps can only hint at what to hide.
No, it’s not a reasonable feature. If I take a screenshot, I want the image to include what is displayed on my fucking screen, period. What is so difficult about this?
When I take a screenshot in ChatGPT, it shows a "share this chat?" toast at the top.
The toast shows up after the screenshot, but my phones's long screenshot feature captures the top part a second time, so the top part of the chat becomes unreadable.
Yup, that's by design. They want to force you to "share" so they can both track who you interact with, and also try to convert the other person into a paying customer.
There should be a layer of user control where the user can make the OS lie to the app. The app has no need to know when a screenshot or recording is happening, what the real location is, what file system contents are, etc.
Side note- The Screenshot culture itself needs to die, sorry. Many a time, a share button simply works. I don’t know why people would share a screenshot or a map instead of pin and share their location. Yes there are cases where a screenshot helps but majority cases simply is “come to this place” a which turns out to make more difficult because people apparently don’t know how to share locations with pin and share!
> Many a time, a share button simply works
It works! Unless:
- the person you’re linking it to doesn’t have an account on that platform
- you’re posting it in a chat, and the site doesn’t implement unfurls correctly
- the site shows a thumbnail on the link, but clicking on it gets hijacked by the “mAkE an aCcOuNt/ login here” shenanigans.
- you’re trying to link to something in context and the sites linking doesn’t support it
- the site is riddled with ads.
- the site is slow to load.
- you’re trying to save something and don’t want to have to load the site every single time in order to refer to it.
- any combination of the above.
Screenshots are much better for archival. So many times you go back to a url/link you shared, and poof it's gone or the content has changed from when you sent it.
Screenshots allows you to get a point in time reference to what you are sharing.
In the case of sharing a link I have to remember/find where it is in each app, likely scroll through a long list of messaging (and for some reason non-messaging apps) to find the correct app, select the contact, and then pray that the link sent actually works for them and contains the correct information I'm seeing (very often the link will actually direct them to a web version of the app I'm using, then put a modal popup in front of the information asking them to use the app, then either send them to the app store, or send them to the app but strip out the actual information I linked and send them to a blank map).
Screenshots are clunky and unideal, but at least they're fast and I know that they don't fail or break or send the wrong info to my contact.
If it were a one off message, this wouldn't be an issue, but if you zoom out on the issue and see you're sending up to a hundred messages a day, points of failure become major life frictions and you're trained out of using things like links in messaging apps.
The ideal "World Wide Web" envisioned by it's original design, was that a URI was a durable pointer to an immutable piece of information.
In 2026, we now know that the information can be edited, or completely removed for many reasons, some legitimate, and some nefarious.
Taking a screenshot is the easiest way to ensure the original is kept for folks to see. Frankly, it'd be even better if (a) the app can signal to the OS information about the url to the page for the screenshot, (b) timestamps were captured in the image and not cropped, and (c) the OS can authenticate the screen shot and digitally sign that it came from an unaltered device.
I totally disagree - the few times I accidentally use a share button, or are forced to use one, the experience is so desperately miserable I am forcibly reminded why I never use them. It's always several clicks, choosing the social platform I need from the millions-long-list which is paginated into pages of like 4 icons at a time (I just want a URL! but you broke your website to force users into the app!) and from there choosing a specific chat or group or whatever from a poorly ordered list that starts with some person I met at a bar twelve years ago rather than the chat I was literally just typing in two seconds ago...
and then when it does send I have no control over the presentation on the other side. Sites love to add some cringe "I love this app SOOOO much hearteyesemoji fire fire fire... sent from my iPhone, made with love in san cupertino" nonsense in my own voice - literally sending their words into my chats using my account, as though I had written their marketing dreck
I also despise this "screenshot blocking" stuff. A device listens is supposed to me, not to the apps. I want a screenshot to be a copy of the raw pixels, and an app should not know about it or have a right to know about it.
Of course this is doable on open source OSes like GrapheneOS, it just sucks that you have to keep modifying the OS every time they release a new version
GrapheneOS doesn't allow for it. You'd need a rooted device to bypass screenshot blocking
Well damn, I would have thought rooting would have been a basic feature of GrapheneOS.
At least it's open source, so maybe one can add root access and screenshot blocking to it.
GrapheneOS is concerned with security more than anything else, to which rooting is completely counterproductive
This is what made me avoid chrome since release, I tried to right click a youtube channel background as a teen wanting to use it as a template to make my own channel background on photoshop... turns out they had disabled it, while I could on firefox.
> I wish, and wish only I can, that this trend goes away at some point.
You don't have to wish, in this scenario. Bluesky supports third-party clients, you can use one that has a more minimal featureset if you prefer.
For Bluesky, sure. I think the comment was aimed at the trend.
Android and iOS should not let apps do this, because it can be (ab)used by apps that you can’t really choose not to use.
I know there’s a popular bank in my country that completely blocks screenshots and screen recordings on Android somehow.
https://developer.android.com/security/fraud-prevention/acti...
In USA Wells Fargo blocks it, so I can't get a picture of the bugs I'm trying to report.
agree with you.
I hate the ChatGPT app and Spotify the most for their screenshot behavior.
Nobody in the comments talking about snapchat where like one of the core pillars of what "sets their service apart" is the difficulty of taking a screenshot without notifying the other party
Wasn’t that the entire premise of the product when it launched? Disappearing messages and minimal footprint so you could be confident your communications were semi-private?
That was the expectation of using the product so it fits and isn’t anything like this discussion.
Yes. And because of the platforms deciding to enable that business model, we're now in a bullshit reality where the very apps that need to be screenshotted most often, are first to abuse platform features and prevent screenshots from being taken.
This deserves a longer rant, but the very premise of Snapchat was always poisonous, and is largely responsible for why, 20 years later, we're now facing extreme proposals for regulating electronic communication.
I generally disagree with the whole line of criticism techies get for "solving social problems with technology", but if there's one unambiguous case where I'd agree it was plain stupid, it's the concept of screenshot prevention, that became prominent with Snapchat. Controlling whether your recipient gets to keep the message you sent them is a purely social problem, and the answer to that in the real world has always, for good reasons, been "once sent, it's no longer yours; once received, it belongs to recipient to do with as they please".
> but the very premise of Snapchat was always poisonous
Wdym? Hooking (primarily underage) people onto "daily streaks" of sharing (often inappropriate) pictures of themselves to (sometimes random) other people via likely insecure servers is a _great_ business model!
Great customer retention. Lots and lots of engagement. So much shareholder value.
That plus product design.
Yellow.
They fuckin did it. Not construction not a warning of some type. Not yellow pages. Yellow - cool looking yellow.
Is what I said to myself as a 20-something product designer
Their entire color story was really cool at the time. Yellow with Magenta/Blue accents was super bold, especially compared to the boring ass direction everything was going. Material and Windows 10 flatshit was all the rage and here comes Snapchat like the Kool-Aid man.
This is why pocket computers are still so unserious. My programs should not be aware let alone respond to my administrative actions like screenshots.
Not only 'pocket computers' are an issue. I was thoroughly shocked when I found out that websites can detect that the dev-tools are open. That is something that a website should never be able to know, yet here we are.
They don't respond to it. It simply says "this button is part of sensitive content", and the OS itself hides the sensitive content, revealing the image below it
have you never encountered the plague of apps saying "don't screenshot, our content looks so much better when you share it, see:" and then displaying a picture of the stupidest looking thing youve ever seen in your life as though you would ever consider showing that to your friends instead of the most personal thing - literally showing them what youre seeing with your own eyes
No, and that's not what bluesky is doing
On iOS, if you swipe control center down and then back up but don’t lift your finger, the screenshot will not have the logo. I do this with Twitter so my screenshots don’t have the X logo.
Interesting that this works. I know I have been frustrated recently when trying to take a screenshot of a bank transfer or something similar, but I couldn't find which app that was to test again. I tested on the iOS Passwords app, and I couldn't get the trick to work in that. I wonder if I'm doing something wrong, or it only works in specific apps.
Each time I tried to take a screenshot of a password, the password was missing from the screenshot - even when I kept the control centre pulled down far enough that the Password app was starting to look blurry.
X and Threads do this too. I wish they all wouldn't, messing with screenshots should only ever be done when preventing them as a security measure.
They shouldn't even disallow screenshots from a security measure. If the user wants to take a screenshot of their bank account info or a password manager they should. Maybe an additional permission for screenshare. No device has protection against a second device taking a recording so it's really just security theater
It's all "security" and all until your banking app has a bug that breaks exporting bank statements and the only way to get it out is to take screenshots - which are blocked as well. Oh, and you need to submit it by today.
At least on rooted Android devices you can bypass that.
Even preventing them shouldn't be possible. It's just security theater anyway. You can easily capture it with another camera.
Until the big players agree on a watermark that their cameras will refuse to photograph.
Reddit as well. Although they let you disable it from what I remember.
I'm confused why people are mad at Bluesky for this. Everyone stating their issues seems more related to Apple than Bluesky. So why point the finger at them?
I don’t think a significant percent of real Bluesky users actually care.
Having a follow button on the screenshot brings nothing and a logo is helpful when sharing (“hey it’s not twitter, I know it looks like it but it’s bluesky”) and looks subtle.
It’s just it’s a forum so people say things for discussions sake and get outraged by anything that a platform they don’t like is doing.
> a significant percent of Bluesky users
42 of their 56 active users might not care about a watermark but god dammit do they respect it
And so should you
Bluesky didn't have to use this API for this purpose.
Okay? Is the purpose bad? Leading to bad things? What's the problem
First - it's great that people can't take screenshots of their sensitive data by accident
Second - I hate when my device keeps me from anything. I'm used to have control over my computer, and this is outrageous that I can't take screenshots of anything I want. There should be a god mode or something like that.
I know of social media sites who have kept an untracked version of the link in the dom of the A tag, but replace it with their in-house link tracker copy of it as you're clicking, that way the destination looks correct when you hover over the link.
A simple call to get a list of sensitive screen areas would suffice. Add a bunch of options to make everybody happy, but don't allow replacement with different content.
This is an interesting case of "Good use" of a "bad feature". This feature is bad because it works against the user and device owner, but this use case like hiding your password when sharing your screen is a good use case.
This is a pretty cool, harmless hack honestly. I don’t see how you could be mad at it.
It feels restrictive, especially since it’s part of a broader pattern of limiting user freedom on platforms. For instance, on PC you can't simply right click on a video and save it on bluesky. They add some frontend bullshit to prevent you from doing that. On "new" Reddit I remember when you saved an image it would always have a watermark on it. On PC, you can't preview the raw image/video either. On Instagram you can't save images at all easily. Cant view content without being logged in, etc.. Now contrast this with platforms like Mastodon where I can do whatever I want with the uploaded media there and there are barely any such restrictions.
Dear app developers: please do not detect screenshots, and do not change behavior. It is my phone and I should have the right to save anything on my screen for my own purposes and you should not know that I do that.
This complaint should be aimed at operating system developers who should have never allow such infringement to begin with.
To be fair this is useful for discovering bluesky from screenshots getting posted on other platforms.
Their product UI kind of looks like X, so it's helpful to know the source of a post
I don't think anyone doubts that it benefits the company.
If only there was some uniform way to identify a resource. But it might lead people out of the walled garden so best not to risk it.
Or, in the case of X, into the outside of the wall of the garden with no way through
Reading between the lines:
Oh, so you can take screenshots of the content that tries to avoid it if you do it mid-switch?
If it's reliable and WONTFIX, that's almost enough to get me to switch away from Android.
Screenshot taking prevention is harmful and should not have ever been allowed to become a platform-level feature in the first place. Because if there's one rule of platform/client interaction, is that if you add a feature that can be abused against customers for stupid reasons, it will be. There's a number of apps I have on my Android phone that block screenshots for dubious reasons, that can be maaaybe charitably explained by calling them "growth hacking pretending to be a security feature", but in some cases even that's a stretch.
This feature should never have existed in the first place.
(At least Bluesky is open about it, both by being Open Source and calling out the "growth hack" by name in source code.)
Unfortunately way more applications inject some sort of info into the image using noise of alpha channels when you take a screenshot... Ofc you shouldn't be doing anything wrong, but let's say you join a court and provide some evidence in confidence, you can be found if that evidence is shared with both lawyers
If the feature can sometimes be useful (including this situation, which some other comments mentioned; but also for other things such as hiding actual secure data), then perhaps it should be made as a setting which can be changed in the setting menu (e.g. "Exclude secure data from screenshots"; it should also mention which apps use this feature), so prevent abuse. (This would also make it clear what the feature is, as well as being able to disable it.)
That such a setting does not exist suggests the feature's true purpose is not for the end user's own benefit!
Once apps can present one thing to the user and another thing to the captured image, there are some pretty weird possibilities
LinkedIn’s job screen in the app is a good example of this different presentation.
I’ve noticed a certain AI recruitment company gets “highlighted” (darkened white background of the screen, but their logo is pure white and REALLY stands out), but when I screenshot it, it reverts to normal, like there’s no blatant special advertising.
Different underlying mechanism. The LinkedIn one (and almost all ads on Instagram/Facebook these days) use a gain map to increase the brightness of the image. Here's a site demoing the tasteful application of this [0], you can see the difference viewing it live versus taking a screenshot of the result.

Ahhh gotcha, thanks for the info
Like adding some nice fingerprinting. I really feel my devices work against me. Nothing works for me.
I appreciate the Game Changer reference
I only ever used bluesky/twitter via web app on my phone, and stuff like this affirms that it's the right decision.
> The “Follow” button is visible when I take the screenshot mid-switch.
Does this indicate that the privacy feature has a gap, where you could reveal the length of your password if you take a screenshot mid app switch?
No because per default the input is not cleared when screenshotting. If you‘d implement this yourself for security reasons you'd most likely blur / overlay the whole screen when the app enters background state.
Probably, but to the extent that was at all a problem to begin with, multiply it by another 0.0001 or whatever for the threat of the screenshot being taken mid switch away!
This technique would be devious if applied to a QR code.
If not for the function being named "GrowthHack" I would have thought that hiding following status for screenshots to be a good privacy measure. They don't use it to hide anything else and since I'm not a user of the app I don't know if there is more extraneous information that could be used to infer or track down who screenshotted and they don't hide.
Is this the relevant issue for Graphene OS?
https://github.com/GrapheneOS/os-issue-tracker/issues/664
Upvote the issue if so.
Why would someone use Bluesky? Isn't that a cesspool of the same midwit scolds, purity spirals, and performative outrage that made Twitter unbearable before the great migration?
I use bluesky for cross posting my blogs
They're just following Apple's lead.
When iPhone shipped, any time you emailed a photo it would append "Sent from my iPhone" to try to virally market. Same or at least similar slimey tactics
There was at least a fig leaf of “I’m typing on a mobile keyboard” excuse my typos”.
That’s just an email signature, configurable (or removable, if you prefer) by the user. This is completely different, in my opinion.
Perplexity does this on web by adding a logo in response to key combos for normal screenshot shortcuts.
This is why I use the browser version for anything. I’m using an actual user agent.
I was wondering about this as well; did they only test with the official iOS app? Or also through a mobile webbrowser?
This sort of stuff to me is an example of fear within an organization. Whenever I see engineering resources allocated towards self promotion and branding rather than quality and features for its users it shows how leaders want control over narratives.
It's equally possible there was one engineer with some free time who thought it would be cool.
This is correct. I was tired of Bluesky screenshots looking bland, no culture of fear needed
Implementing a watermark isn't a thing anyone thinks is a cool feature they want to try out.
what do you mean, it's a very normal cool thing that everyone loves
Sent from my Ryobi Riding Lawnmower
I mean. I read this and immediately thought it was a cool thing I'd like to try out
By the end of your first year in CS you will have hopefully learned enough to place an image on something, that's about as cool as it gets.
It's probably silly to make OP's judgement of any of these implementations in isolation, but you can sense a real fear about the growth (or lack thereof) inside Bluesky. Fiddling with the presented metrics (likes count getting moved ahead of reposts), promoting total user signups while being silent on collapsing DAUs. They are promising a lot at once with AI custom feeds from Attie and subreddit-style communities that smells like feature creep.
Your indicators that we're afraid about growth is that we're shipping features and experimental new products?
They aren't my indicators, but they read as sweat against the observable metrics being in decline. There is a perception that they want to pull on users outside of Bluesky that I don't really think exist, and I guess I share in that feeling when I believe the core still has so much basic parity missing with X et al that would demonstrate confidence in the current users you already have. Still interested to see what they ship as.
Adding a watermark, how radical, dude
And such engineer would have enough organizational clout to just ship it without going through anyone?
That's how a modern organization works. You trust your colleagues will do good work, and will ship something useful and there's not really "someone to go through".
I agree this can be defined as cool and very very likely someone did this on their free time/prompted Claude on the side.
It's a Series B company, it needs to make money, and they have to answer to a board and provide information to investors. They have a roadmap, direction, and leadership. Yes, trust and good intentions is an awesome thing and I hope they have that indeed, but I would think reality lies in the middle of both sides.
I've worked at a Series B company and reality is this is too minor for investors to care on its own, and it's also very hard to correlate this change to new revenue, so not something that's likely to have been done with that intention
I guess we had very different experiences. Maybe it’s the B2C industry or these free apps
Bluesky has <100 employees so it could be possible
I agree that having less people to manage means easier to build trust relationships and culture, though I believe some form of management and control must exist.
I'm sure this wasn't even in the top 10 of things that we made sam implement out of fear
Yes actually Sam often ships random fun things he feels like doing.
You're fun
Marketing, like every other functional part of a business, requires technology and engineers. This has nothing to do with fear, you just don’t respect non-engineering work as critical to running a business.
Someone spending half a day on a feature that places the app's logo in the screenshot so people seeing it can know where it came from is "fear within an organization"? You've got to be kidding lol
X does the same thing.
Just since Nikita joined (altho now he's gone, doubt they will remove it tho)
Does anyone know a way to do this for a computer? I built a p2ppoker website the protects the shuffle from the server but I would like to blank the cards on screenshots to prevent huds and AIs from making the game unplayable.
I’m interested in reading more about this. how does p2ppoker work out?
This trick was almost certainly invented by Nikita Bier when he joined X.
I’ve noticed that if you screenshot a thread in the threads app an “@threads” logo appears in the upper right corner
Tiktok has been watermarking videos since the beginning.
Usually post http://aidr.wtf appropriately.
> Thankfully, I remembered that Bluesky app is open source (or at least the code is available to look at).
What does the author mean by this? I checked the repo and the project seems to be MIT licensed, which makes it open source.
Is this iPhone only? I've never seen this on Android.
It's iOS only, relying on iOS to exclude isSecureTextEntry things from screenshots:
https://github.com/mozzius/expo-privacy-sensitive/blob/main/...
I think RevenueCat does the same thing. Smart way to exploit network effects!
has this guy lived on a rock? reddit/twitter/etc every social media platform does this already.
the difference is those apps aren’t open source so you can’t go explore how they work
It's pretty likely that bluesky users aren't on other social media. Because it pretends to be better than them (this shows it isn't really, though)
I know you don't think it's bluesky, but which app do you think is better at putting its logo on screenshots?
That's not what the other commenter is saying. The other commenter is stating that by doing this logo trick, bsky is very similar to competing platforms

Companies always want to slop-spam their logos onto everything. It is a very annoying habit. On youtube videos this is even more annoying; several use floating logos.
As Spring inevitably leads to Winter, and Night follows Day, Thus the Inevitable Enshittification of all Centralized Platforms
This is arguably missing the "how" from the title -- can someone fix?
The best way to ask for this is to send an email, to the email address which you can find at the bottom of the page (click on "Contact"). There's no guarantee that the mods will find your comment otherwise.
@Dang: I would like to report an innocent victim to the automatic "How"-Removal.
Saying @dang has no effect; it does not activate a batsignal or any other mechanism of mod summoning. The only way to be sure a mod see this is to email them; see the contact link in the footer and include a link to the comment.

Tangentially, I see a lot of people here upset that apps can react to your screenshot before it is captured. I think it is helpful to think about it as a tradeoff between freedoms:
(a) the freedom to screenshot any content on your own device (b) the freedom to share content with others that cannot be screenshotted
It can be annoying when DRM or privacy features block a screenshot, but I think it can also benefit the platform ecosystem that you participate in as a user too. Idk!
B is an illusion, and it seems like about 90% of the time it's used for dumb or bad purposes even if it did work.
Locks can be picked. We still make and use locks.
If a type of lock was overwhelmingly used for bad reasons, and only worked when someone didn't cover their hands (analog pictures), I'd be arguing against that type of lock too.
Is it a “bad reason”? Millions of people chose to use Snapchat specifically because of how it handles screenshots. It is a feature even if you don’t like it.
Many people would find it inconvenient to find another device to take a picture with. And that manual picture would then have baked-in evidence that it was taken surreptitiously.
Locks keep honest people honest, as long as the app is up front about it and lets users make the choice, I don’t mind.
I said 90% and not a higher number because of Snapchat. It's not the example of bad reasons.
Nobody deliberately opted in to random information hiding in a more general purpose app, or watermarking, or DRM.
Another view of it is that’s just a creative use of the medium. An interactive button doesn’t serve any purpose in the screenshot, so why not find a better use for that space.
When I’m in Safari, taking a screenshot can turn into a totally separate operation (full page scrolling screenshot) and that’s a good feature.
Others complain about Google Maps showing a popup telling the user about location sharing upon screenshot - I think that makes a lot of sense, considering it doesn’t show up in the screenshot and dismisses easily.
I’m very harsh on user hostile choices, in fact I spend a lot of time ranting and raving about it, but I just don’t see that here.
The ability to show exactly what you had on your screen is one of the biggest uses of screenshots. The ability for apps to do this kind of thing breaks that use.
Offering something better can be valuable (sometimes) but don't alter the screenshot itself.
