The sole purpose of this app is to back up the current wallpaper. Up to Android 13 you need to grant the "READ_EXTERNAL_STORAGE" permission to access the wallpaper. On Android 13 and higher it is necessary to grant the "MANAGE_EXTERNAL_STORAGE" permission. This permission also allows read and write access to all user files on the device. The app does not use the permission to access any files though. This is a limited version. Get the full version from Github or F-Droid: https://f-droid.org/
