AppLock: Privacy Guard

Smart AppLock keeps your private apps private. Lock any app on your phone behind a PIN, a pattern, or your fingerprint — so messages, photos, banking and social apps stay yours alone, even when someone else is holding your device. Setup takes under a minute. Pick the apps you want protected, choose your unlock method, and AppLock quietly handles the rest in the background. LOCK ANY APP • Protect social, chat, banking, shopping and gallery apps • Choose exactly which apps to lock — everything else opens normally • Newly installed apps can be locked automatically, so nothing slips through UNLOCK YOUR WAY • 4-digit PIN with a clean, one-handed keypad • Pattern lock with a smooth draw-to-unlock grid • Fingerprint and face unlock on supported devices • Vibration feedback while entering your PIN or pattern NEVER GET LOCKED OUT • Set a security question during setup • Forgot your passcode? Answer your question and regain access • No account, no email, no phone number required REAL PRIVACY PROTECTION • Block screenshots and screen recording inside protected apps • Choose when apps relock: immediately on leaving, when the screen turns off, or after one minute • Protection restarts automatically after you reboot your phone OPTIONAL HOME SCREEN Smart AppLock can also work as your home screen, with a customisable app grid, dock, app drawer, search and gestures. This is completely optional — skip it and the app works exactly the same as a standard app locker. SIMPLE, PRIVATE, LIGHTWEIGHT • Your PIN, pattern and security answer never leave your device • No sign-up and no personal details needed to use the app • Built to stay light on battery and memory PERMISSIONS WE ASK FOR — AND WHY • Usage Access: lets AppLock detect which app you just opened, so it knows when to show the lock screen. This is the core of how app locking works. • Display Over Other Apps: draws the lock screen on top of a protected app. • Notifications: shows the ongoing protection status. • Start On Boot: restores your locks after a restart. • Battery Optimisation: keeps protection running reliably in the background. We do not collect, upload or sell your personal data. AppLock never reads the content of your apps, messages or files. Smart AppLock is free and supported by ads. Questions or problems?
