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.

I've used this app for years if not for up to a decade! It's been nothing short of excellent in locking my apps & especially gallery (pics & vids). Highly recommended, a little drawback is the ads tho which can be a little hectic and sometimes unskipable requiring you to exit & reopen. Although it's a fair price to pay for it's performance and being free to use

I have been using the app for a long time, but after some update, the app started doing something unexpected from version 3.5 to the latest version. My phone's screen light always goes off whenever I watch videos on the app. The issue still persists even with the latest update. I had to uninstall the most recent version and install version 3.2 to be able to watch videos without the issue. Please try and fix it

I love this app!!! I've never seen an ad on it and I've had it a significant amount of time. Also, no problems with unlocking between apps, although it likes to slam Google Play shut quickly if the install (an app) button is visible on the screen. As long as I scroll down immediately after opening a page it will remain "propped" open for me.
