Permissions
On Android, app permissions shall regulate access to resources and guarantee a certain form of „privacy”. Unfortunately, on-board utilities are a complete failure here – as they are either non-existing (up to Android 5/Lollipop), or much too low granular (Android 6 and up). A must-read on this topic is Das Android Berechtigungsmodell: Ein perfides Konstrukt by security expert Mike Kuketz (Googletranslated English variant here). So we have to substitute with 3rd party utilities – to inspect what apps have access to (possible without root) as well as to regulate that access ourselves (usually requires root).

APK Rebuilder
Manipulate the .apk file of (user-) apps, and re-install those. They don't require root; but usually, updates for those apps no longer work.
