Hi
Before I switched to Fairphone2 I used until Android 4.2 SRT Appguard (on a rooted HTC Desire HD with Cyanogenmod 4.2) to restrict permissions on apps. But because the app changes the code of the app you wanted to be restricted - you won`t find it in the Google Play Store.
But, you have to be very cautious with Android 5.1. There seems to be some issues (maybe similar to LBE Security Master) and won`t work on every phone - see also:
