AppLock: Lock Apps & Vault

Lock apps with a PIN, fingerprint or face unlock, hide private photos in an encrypted vault, and see who tried to get into your phone. AppLock keeps your chats, photos and accounts private, and it can even disguise itself.

🔒 APP LOCK — PIN, FINGERPRINT & FACE

• Lock any app with a 4–6 digit PIN

• Unlock instantly with your fingerprint or face

• The lock screen appears the moment a locked app opens

• Re-lock after the time you choose, or lock apps on a schedule

• Protection restarts automatically after a reboot

📸 INTRUDER ALERT

Someone entered the wrong PIN? AppLock quietly takes a front-camera photo. Intruder history shows the photo, the time, the app and the PIN that was tried.

🖼️ PHOTO VAULT

Move private photos, videos and files out of your gallery into an encrypted vault that only you can open, with a built-in private viewer.

🎭 FAKE PIN — DECOY MODE

Forced to unlock your phone? Enter the fake PIN instead. AppLock opens with an empty vault and none of your locked apps shown. On a locked app, the fake PIN simply closes it.

🧮 DISGUISES

Hide AppLock behind a real, working calculator, or as Notes, Timer, Flashlight or Compass. Only you know the secret way in, and you can practise it before switching.

👥 GUEST MODE

Lending your phone to a friend or a child? Turn on guest mode and only the apps you choose can be used. Fastest way: open an app, swipe down and tap the Guest mode tile in Quick Settings.

🌐 PRIVATE BROWSER

Browse without history or cookies.

⭐ APP LOCK PREMIUM

Fake PIN, the full intruder history, the extra disguises and guest mode are part of Premium: monthly, yearly (with a free trial for eligible users) or a one-time lifetime purchase. Locking apps, the photo vault, intruder photos and the calculator disguise stay free.

🛡️ YOUR PRIVATE CONTENT STAYS ON YOUR DEVICE

Your PIN, your hidden files and your intruder photos are stored only on your phone, and vault files are encrypted. AppLock never reads your screen content, messages or typing. The Accessibility permission is used only to detect which app is opening, so the lock screen can appear instantly.
