Apps ask for a lot of permissions when you get on them. Locations, files, calling, just so many things. Most of the time these permissions are important to the function of the app. But even so, you may not want to keep them going when the app isn’t in use. Bouncer is the app that lets you grant temporary permissions to your apps without forcing you to go into settings.

Whenever you allow an app a permission, you get an extra dialogue that asks you if you want to keep it or remove it when you’re done. If you say remove, once you’ve shut down the app, that’s it, it’s no longer allowed.

This will help your phone’s battery life and may give you some piece of mind when it comes to your privacy and app usage. Although it’s not all apps, some do sell information to third parties. You can download the app in the play store for 99 cents.
