About this app
AppLock protects your apps, photos, and videos with a PIN, pattern, fingerprint, face unlock, or a hidden knock code — and keeps everything else about your phone completely private. No ads. No login. No data ever leaves your device.
🔒 LOCK ANY APP
Choose any app on your phone — WhatsApp, Gallery, banking apps, social media — and require unlock every time it's opened. Supports PIN, pattern, biometric (fingerprint/face), and a secret knock-code rhythm.
🖼️ HIDDEN VAULT
Move private photos and videos into an encrypted vault (AES-256) that's removed from your regular gallery and Google Photos entirely — not just hidden, actually gone from anywhere else on the device. Auto-hide new screenshots from a folder you choose, or share straight into the vault from any gallery app's Share button. Bulk select, release, or delete anytime.
👤 GUEST MODE
Hand your phone to someone else without worry — Guest Mode locks everything except the one app you allow, on a timer, and reverts automatically.
📸 INTRUDER LOG
Optional front-camera photo captured on a failed unlock attempt, so you know if someone tried to get in — stored encrypted, viewable only by you.
🎭 DISGUISE MODE
Make AppLock's own icon look like a plain Calculator — a real, working calculator until you type your secret code.
🛡️ SECURITY SCORE & STREAK
A live score shows how well protected you are, with one-tap fixes for anything missing — plus a daily streak to keep you on track.
🚨 PANIC LOCK & BREAK-IN ALARM
Instantly lock everything from a Quick Settings tile or notification button. Turn on a loud alarm that triggers after repeated failed unlock attempts.
🧰 BONUS TOOLS
Screen Time dashboard, Weekly security recap, Unit Converter, Flashlight, Compass, QR Scanner & Generator, PDF Toolkit (images to PDF, merge, compress), Photo Compressor, and Duplicate Photo Finder — all built in, all free, all processed on your device.
🔐 YOUR PRIVACY, ACTUALLY RESPECTED
• No account or sign-in required
• No analytics, no crash reporting, no advertising SDKs
• No network requests of any kind — everything works fully offline
• Camera and file access are used only for the specific feature you turn on, only while you're using it
• Your PIN, pattern, and recovery code are stored only as salted cryptographic hashes — never recoverable, not even by us
Download AppLock and take real control of your phone's privacy — free, no ads, no catch.
