AppLock - Vault Security Loc is a free application developed by Security Lab for Android devices. This program provides users with a secure way to protect their private information from curious people. With App Lock, you can set a password for any app, ensuring that only you can access it. This feature gives you peace of mind and eliminates the need to worry about your private information being leaked.

App Lock also has a Vault feature that allows you to encrypt and store photos, videos, and files securely. If you have any sensitive photos or videos that you don't want others to see, you can add them to App Lock. The file will only be opened and viewed in AppLock.

The app supports three password modes: Passcode, Pattern, and Fingerprint. You can switch between them easily and choose the one that suits you best. With App Lock - Photos Vault & Files Protector, you can have more security and keep your sensitive data safe.
