This app provides a shortcut to the hidden feature App Ops in Android 4.3. This allows you to selectively disable some permissions for the apps you have installed on your device (without requiring root).
Be very careful using this feature. Google purposely made this a hidden feature as there’s currently no warning if you break a feature in an app.
