【Permissions and Privacy Policy】

--------------------------------------------- To enable the screen locking function, the Android system requires such applications to obtain "Device Administrator" permissions.

We solemnly promise you:

● "Blackout" will only use this permission to execute the single command "Lock Screen".

● This application **will not** collect, store, read, or transmit any of your personal data or device information.

● Your privacy is our top priority. We are a tool, not a tracker.
