AppLock is a security app for Android, protecting you from unwanted uninstallation and changes to your apps, files, and data. You can lock your apps and folders to prevent others from deleting them, or hiding files to hide from your friends. With the built-in password manager, you can keep your credentials safe with strong passcodes, and never lose access to the apps you use every day. You can also protect your device from unwanted access with a pattern, fingerprint, or passcode.

AppLock also protects your files and data by hiding it in folders or locking it with a passcode. You can lock a folder to prevent others from opening it, and lock files and data to prevent them from being edited or changed. You can also use AppLock to add a password to a single app or folder to prevent others from accessing it. If you use AppLock on multiple devices, you can sync all of them in the app.
