Lock Your Notes with Face ID or a Fingerprint
Hand someone your phone without worrying about your diary. Lock Memory Chat with Face ID, Touch ID, or a fingerprint.

The moment you hand over your phone
You pass your phone across the table to show someone holiday photos. Or your nephew wants to play a game on it. Half a second later you remember what else is on there: the diary entry from last night, the list of gift ideas, the note about your doctor's appointment.
Memory Chat can lock with Face ID, Touch ID, or a fingerprint on devices that support it. Whoever's holding your phone can swipe through photos all they like. Your notes stay closed.
How the lock works
- Opens with your face or finger, using whichever biometric method your device supports
- Blurs Memory Chat's screen when you switch apps, so nobody reads your notes in the app switcher
- Locks only the sensitive Memory Boxes, or the whole app if you prefer
- Never shows us your face or fingerprint: your phone's operating system checks it, and Memory Chat only gets a yes or no
What's worth locking
A daily diary is the obvious one. Worries, hopes, things you wouldn't say out loud. It's also where gift planning belongs, since a surprise isn't much of a surprise if your partner finds the list while borrowing your phone. And health notes, like wellness goals, what the doctor said, and symptoms you're keeping an eye on, are nobody's business but yours.
How to turn it on
Biometric app lock is part of Super Memory and Ultra Memory. Go to Settings, open Security & Privacy, switch on the method your device supports, and follow the prompts.
