iPhone Clipboard Privacy: Which Apps Can Read It?
iOS already guards the clipboard. Since iOS 16, an app must ask before it reads what you copied in another app. You can say no. What it cannot do is stop a copy from reaching your other Apple devices or sitting there until you replace it.

What do I need to know?
- Apps must ask. Apple: "Apps need to get your permission before accessing the pasteboard to paste content from another app."
- Your own paste is not a leak. When you choose to paste into an app, you are handing it the text on purpose.
- Copies travel. With Handoff on, what you copy can appear on your nearby Mac or iPad.
How does the paste prompt work?
Apple's developer documentation says that "in iOS 16 and later, programmatic pasting raises a user alert." That means an app reading the clipboard on its own, without you asking, triggers a prompt.
- You copy something in one app.
- You open a second app, and it tries to read the clipboard.
- iOS shows a prompt asking whether to allow the paste.
- Tap Don't Allow if you did not expect it.
Apple also says iOS will "let you know when an app accesses your Clipboard." Both quotes come from Apple's privacy controls page and the UIPasteControl documentation.
Why does an app keep asking?
Some apps check the clipboard each time they open, for example to offer a link you just copied. The prompt is iOS doing its job. If you trust the app and it keeps asking, look at its page in Settings. If you do not trust it, keep denying, or delete the app.
Where else does my clipboard go?
Universal Clipboard sends copies to your other Apple devices. Apple says it works when the devices are near each other, signed in to the same Apple Account, with Bluetooth, Wi-Fi and Handoff on. Handoff is on by default.
Apple says the copy "remains there briefly, or until you replace it by copying something else on either device." See Use Universal Clipboard.
To turn it off on iOS 27:
- Open Settings → General.
- Tap AirPlay & Continuity (or AirPlay & Handoff).
- Turn off Handoff.
Apple gives this path on its Handoff page. Turning off Handoff also turns off the other features that rely on it.
How do I keep secrets off the clipboard?
- Let passwords fill themselves. With Password AutoFill on, your iPhone enters saved passwords without copying them.
- Overwrite after copying something sensitive. Copy a single harmless word once you have pasted it.
- Do not copy codes or card numbers into chats. Type them where they are needed.
- Check what you share in a screenshot. A copied number on screen is caught in the image.
What this doesn't protect against
The prompt only covers apps reading the clipboard on their own. Once you paste text into an app, that app has it. A keyboard app you have given full access, or a phone with malware, is outside what the prompt can see.
Do it with Cryptile
Cryptile keeps notes, photos and files in an encrypted vault. A card number or a recovery code can live there instead of in a plain note. When you do copy a secure note, the copy expires from the clipboard after a minute. Each item is encrypted with AES-256-GCM under a key made on your device from your pattern. There is no account and no server.
Cryptile is free for up to 2 vaults, 100 photos and 10 videos. Plus adds search inside the vault and the panic pattern for $19.99 a year (7-day free trial) or $39.99 once.
