On iOS, it now shows you when an app accesses the clipboard. I discovered my weather app is snooping on my clipboard, which is very interesting, especially since I never pasted, and there's no logical reason why it would have needed to view the clipboard:
I very much appreciate this feature on iOS because it creates the right incentives for apps to view only what they have to.
Is there any way to enable this feature on macOS, where a small popup could appear if an application views what's on your clipboard?
