A simple app locker for Android

Choose the apps you want to lock. When someone opens a locked app, SvarLock asks for your PIN or supported biometrics.

• Lock apps such as WhatsApp, Instagram, Gallery, email, notes, and banking apps.
• Search your app list and choose which apps to lock.
• Apps relock when you switch away or turn off the screen.
• Choose light or dark mode.

SvarLock focuses on app locking. It does not move or hide the files inside your apps. There is no cleaner, booster, browser, or photo vault.

• No account, sign-up, or email address required.
• No analytics or tracking SDKs.
• No advertising ID.

• No collection, sale, or sharing of your personal data.
