App Lock: PIN & Pattern

Lock the apps that matter, in one tap
Pick gallery, chat or payment apps already on your phone and protect them instantly.

Only you can unlock
Set a 4-digit PIN or a pattern. Both stay on this device.
• 4-digit PIN — quick to enter, always exactly 4 digits
• Pattern — connect at least 4 dots

Fingerprint or face
Unlock faster with a fingerprint or face already saved on this phone.

When it locks again
The timer starts when you leave a protected app. Come back before it ends, and you won’t be asked again.
• As soon as you leave
• When the screen turns off
• 30 seconds after you leave
• 1 minute after you leave
• 5 minutes after you leave

New apps, your call
After you install an app, you’ll get a quiet reminder so you can decide whether to protect it.

Privacy stays on this phone
These permissions only detect app switches, show the unlock screen, and keep protection running. They don’t read on-screen text, photos, messages, or anything inside other apps.
