Locks the moment you leave
Leave Underlock, even for a second, and the vault locks. In App settings, you can choose 1 or 5 minutes instead.
Your private photos, encrypted on your iPhone
Everything you add to Underlock is encrypted on your iPhone before it’s saved. We never receive your files, your pattern or your keys, so there’s nothing for us to see.

- Encrypted on your phone
Encrypted before anything is saved. Names and dates too.
Photos, videos, files and notes are encrypted on your iPhone before they’re saved, and so are their names and dates. Without your pattern, your passphrase or your recovery phrase, your files are unreadable. A passphrase is words you type instead of drawing a pattern. Your recovery phrase is the 12 words you wrote on paper at setup. If you turn on Face ID in a vault, your face opens that vault too.
What else keeps your vault private
A plain cover in the app switcher
Switch apps, and a plain cover hides what’s on screen.
No account, no email, no analytics
Underlock never asks who you are, and never reports how you use it.
