About this app

Keep your private apps truly private. App Lock lets you choose which apps need a password before they open — messages, photos, social media, banking, and more stay protected even if someone picks up your phone.

🔐 LOCK ANY APP
Browse your installed apps and turn protection on with one tap. App Lock appears instantly when a locked app is opened, so nosy friends, family, or strangers can’t peek at your content.

🔑 MULTIPLE UNLOCK METHODS
• 6-digit PIN — quick and secure
• Pattern lock — draw your own unlock pattern
• Fingerprint — unlock with one touch (on supported devices)
• KnockCode (Premium) — a unique tap-based code only you know

🛡️ ADVANCED PROTECTION
• Intruder Selfie — capture a photo after repeated wrong unlock attempts
• Spy Alarm — sound an alert when someone keeps guessing your password
• Fake Error Screen — show a “app has stopped” message instead of the lock
• Lock Recent Apps — block access through the Recents/Overview screen
• Hide Notifications — suppress alerts from locked apps on your status bar
• Uninstall Protection — require your password before App Lock can be removed
• New App Alert — get prompted to lock apps as soon as they’re installed

📁 SAFE VAULT
Store photos and videos in an encrypted vault on your device. Import from your gallery, view securely inside the app, and export only when you choose.

🎨 MAKE IT YOURS
Pick from beautiful lock-screen themes, set a custom wallpaper, and choose when apps relock — immediately, when the screen turns off, or after a set time. Auto-disable scheduling lets you relax protection during trusted hours.

🕵️ STAY HIDDEN
Disguise App Lock as Calculator, Clock, Notes, or Gallery so it blends in on your home screen. Stealth Mode can hide the icon entirely — reopen the app with a secret dialer code.

🔁 FORGOT YOUR PASSWORD?
Set a secret question during setup to reset your password if you ever forget it. Your answer is stored only on your device.

📋 PERMISSIONS & PRIVACY
App Lock needs Accessibility access to detect when a locked app opens — this is how app lockers work on Android. It does not read, collect, or share your screen content. Optional permissions (camera, display over other apps, notification access) are used only for features you turn on, such as intruder photos or showing the lock screen. Your PIN, vault files, and intruder photos stay on your device.

Download App Lock today and take control of your privacy — one app at a time.
