Description
🛡️ Protect Your Privacy with AppLock
Tired of worrying about snoopers checking your private messages, photos, and sensitive data? AppLock is the definitive security solution designed to protect your privacy across all your applications and files. Use the robust combination of PIN, Pattern, or Biometric Authentication (Fingerprint) to lock any app, ensuring that only you can access your personal information. AppLock is more than just a simple app locker; it's a comprehensive privacy suite that includes an Intruder Selfie feature to catch unauthorized access attempts and a secure Photo Vault to hide your most private media.
✨ Key Features That Ensure Maximum Security
1. Powerful App Locking Methods Triple Security Layer: Lock any application (Gallery, WhatsApp, Facebook, settings, calls, etc.) using your preferred method: Pattern Lock: Draw a unique shape for quick, secure access. PIN Lock: Use a numeric code, which is easy to remember yet hard to guess. Biometric Authentication: Instantly unlock apps using your Fingerprint (if supported by your device), offering the fastest and most secure method.
2. Intruder Selfie: Catch the Snoopers Automatic Detection: AppLock automatically takes a photo of anyone who tries to unlock your applications with an incorrect password or pattern several times. Invisible Proof: The photo is captured silently and the evidence is stored securely inside the app, showing you exactly who tried to break into your phone.
3. Secure Photo & Video Vault Private Gallery: Easily move private photos and videos from your device gallery into our protected vault. These files are encrypted and completely hidden from public viewing and other apps. Unbreakable Security: Only you can unlock the vault using your master PIN, Pattern, or Fingerprint.
4. Enhanced Privacy Protection Notification Lock: Prevent others from reading your sensitive notifications (e.g., WhatsApp, Messenger) on the lock screen or notification panel. Invisible Pattern: Hide the draw path of your pattern to ensure nobody can see your unlock key, even if they are watching over your shoulder. Time-based Re-lock: Customize when apps should re-lock (e.g., immediately, after a few minutes, or only after the screen is off).
5. Optimized User Experience Low Memory Usage: AppLock is designed to be lightweight, fast, and consume minimal battery power. User-Friendly Interface: Set up and manage your locked apps with an intuitive and easy-to-navigate interface.

It is very good app I have recently used
★★☆☆☆D Gove· Dec 29, 2025
This app wants to many permissions, it doesn't need all those permissions to work, it's an invasive thing, I uninstalled it as soon as I could, I would not trust this app, it's too invasive.
