The third Developer Preview of Android 11 includes an option for users to automatically disable permissions for apps that are not used for a prolonged period of time.
According to Neowin.net’s article on the new feature,
The feature is named “Auto revoke permissions” and it is disabled by default. It is buried deep inside the App permissions menu in the Settings app at the bottom of every app listing. The feature needs to be enabled manually for apps that you have installed on your Android device and there’s no global toggle for it. Seemingly, the feature does not revoke all permissions from an app when it is not used in months. It is also unclear as to how long it takes for the feature to revoke permissions from an unused app.
Good idea, but this should a) be a system-level toggle, b) create a notification when an app’s permissions have been revoked, c) add a notification system that simply lets users know when an app they have installed hasn’t been used in X days (where X days would be user definable), and d) when such an app is accessed again, there needs to be a notice to users that permissions were disabled automatically along with the requisite screen for users to indicate whether they would like to re-enable those permissions.
