Short version: saved notifications never leave your phone. Intruder photos leave it only if you sign in to AppLock Web. Android handles your fingerprint and face, not App Lock.
What each permission does
| Permission | What App Lock uses it for |
|---|---|
| Display over other apps | Shows the lock screen on top of a locked app the moment it opens. |
| Usage access | Tells App Lock which app is on screen, so it knows when to lock. |
| Accessibility (Optimize App Lock) | Detects locked apps faster, and powers Lock Recent Apps and Lock Uninstalling Apps. |
| Device admin (Advanced Protection) | Makes App Lock harder to uninstall, and detects failed attempts to unlock your phone for Device Intruder Alert. |
| Notification access | Hides previews from apps you choose and saves those notifications. Saved notifications stay on your phone. |
| Camera | Takes intruder selfies after a wrong unlock, and remote pictures you request from AppLock Web. |
| See installed apps | Lists the apps on your phone so you can choose which to lock. |
| Fingerprint and face unlock | Lets you unlock with biometrics. Android checks your fingerprint or face; App Lock only learns whether it matched. |
| Notifications and background running | Keeps App Lock running so locks work all the time, and shows alerts. Ignoring battery optimization stops your phone from closing it. |
| Internet and advertising ID | Shows ads, sends crash reports and analytics, handles the ad-free subscription, and syncs AppLock Web if you sign in. |
| Bluetooth, Wi-Fi, sync and system settings | Used by the advanced lock options and the alarm features. |
What stays on your phone, and what doesn't
- Stays on your phone: your list of locked apps, schedules and groups, saved notifications, and intruder photos unless you sign in.
- Sent to our service providers: ads and analytics (including your advertising ID), crash reports, and subscription status.
- Only if you sign in with Google: your email address, your recent intruder photos, and remote captures, so AppLock Web can show them.
Tips to stay safe
- Set a strong screen lock on your phone as well as in App Lock.
- Turn on Lock Uninstalling Apps and Advanced Protection so App Lock is hard to remove.
- Set a security question in Settings › Security Settings in case you forget your lock.
- Only install App Lock from Google Play.
