App Lock

App Lock is a privacy-focused AppLocker tool that helps you secure apps and personal content using a password, fingerprint, pattern, or knock code. You can lock and hide selected apps, block unauthorized access, and keep sensitive information away from anyone who borrows your phone.

Lock Any App You Want

App Lock lets you lock popular apps such as Facebook, WhatsApp, Messenger, Calls, Gmail, Snapchat, and Google Play. You decide what stays accessible and what requires authentication, so you keep control over social apps, messages, and settings.

Hide Photos and Videos with a Secure Vault

App Lock can protect your gallery by placing photos and videos inside an encrypted vault. You can hide personal memories and private media so nobody can view them without your chosen lock method.

Multiple Lock Methods (Fingerprint, Password, Pattern, Knock Code)

You can choose the unlock style that fits your routine:

• Fingerprint lock (on supported devices)
• Password lock
• Pattern lock (with an option to hide the draw path for more privacy)
• Knock code

Intruder Selfie for Extra Security

When someone enters the wrong password, App Lock can capture an “intruder selfie.” This feature helps you see who attempted to access your locked apps.

Smart Locking Features for Daily Convenience

App Lock includes tools that make protection feel seamless:

• Auto-lock new apps: detect newly installed apps and lock them quickly
• Real-time locking: apply the lock immediately so app content doesn’t show first
• Re-lock timing controls: set when the app should lock again to reduce repeated prompts
• Hide from Recents: reduce the chance others find the locker in your recent apps list
• Password recovery: reset access using security questions if you forget your password
• Random keyboard: reduce the risk of password guessing or shoulder-surfing

Customization: Themes, Icons, and Lock Screen Options

You can personalize the experience with themes and lock screen settings. The app also lets you disguise the App Lock icon with an alternate/fake icon to make it less obvious to snoopers.

Permissions (What the App Needs and Why)

• All Files Access: the app needs this to hide and protect photos, videos, and files in the vault.
• Accessibility permission: the app uses this to improve locking speed, support performance features, and help with battery optimization behavior. The developer states the app does not use these permissions for other purposes.
