The description of Superuser
Own and manage your Android privileges
Superuser is an app that lets you manage all the privileges on your Android with full freedom. To do this, of course, you'll need to have a root device. With Superuser you can grant and manage Superuser rights for your phone.
Once you have Superuser installed you can easily manage all the privileges for each app you have installed on your device. With just a touch, you can enable and disable any permissions you've previously granted. You can also temporarily unroot your device.
Superuser also helps you to uninstall bloatware and system apps pre-installed by phone carrier or manufacturers, and also user apps in one click.
This app requires that you already have root, or a custom recovery image to work.
This app cannot be uninstalled if it was installed with your ROM or root.
Permissions requested are for:
Internet – updating the binary
External storage – backup/restore for elite users
NFC – creating an allow tag for elite users
Boot completed – fix database on boot
