FAQ:
• How if I forget the lock screen?
Because this app doesn't want to use Internet access (for your privacy), so it doesn't support password recovery via internet such as email.
If you forget password, you can clear app data or re-install app.
But if you activated the device admin and also locked Settings app, you will no longer be able to clear app data or uninstall app.
So please try to not forget the password!

• Why can't I activate App Locker again after force stop?
If you can't activate App Locker after already turned on the accessibility service for App Locker, then please try to turn off the accessibility service and turn it on again.
