Re: iif clipboard read allowed without user OK
iOS 14 includes something that will let you know if an application has read the clipboard. Not sure if it will let you control each access or not.
It also puts up little dots in the notification area if the application is accessing the camera or the microphone (each of which do require permission) so you can tell if something you've given permission to listen/watch is doing so at times when it should not or you do not expect it.
It also lets you limit access not just to the photo roll, but to a particular photo from the photo roll, should an app that you give permission so it can upload one photo decide to help itself to all of them. Not sure if they did that because an app was discovered doing so, or just being extra cautious.
They do improve on the privacy in new ways every rev, because developers keep coming up with new ways to act shitty.
