Please enable Advanced Protection in Protect of AppLock, so nobody can uninstall or kill AppLock without password. You can disable Advanced Protection when you don't want it. 4)I forgot my password, How to find it? Update to the latest version first. And then tap AppLock icon, click the icon at top right corner of lock page, tap 'forgot password'. 1. Security answer: enter security answer, click 'reset password'. 2. Security email: click 'send code to security email', input reset code, click 'reset password'. AppLock uses the Device Administrator permission. To enable Advanced Protection, please activate AppLock as "device administrator". It's only used for preventing intruders uninstalling AppLock. To enable the power saving mode, please turn on the Accessibility Service. Once enabled, AppLock can monitor foreground app changes in real time, to improve locking and unlocking efficiency, reduce battery consumption, and ensure the stable operation of AppLock. Why does AppLock need this permission? We've received a lot of user feedback complaining that the lock fails after the phone restarts and their apps lose protection. This issue mainly stems from the delay in detecting changes in foreground apps. With Accessibility services enabled, AppLock will be informed when any app is opened and provide instant protection for locked apps, and reducing battery consumption. What data we will collect and how to use? AppLock doesn’t use Accessibility Service to collect any data. We only use it to monitor foreground apps.
