What you can do

Some notes are nobody's business.

Cipher is a sealed vault for the notes you'd least want seen. A 4-digit code only you know. Face ID if you want it. And an app that locks itself the instant you leave.

More app details

DESIGNED LIKE A TERMINAL Phosphor green on obsidian black. Monospaced type, scanlines, redaction bars. In your list, note contents render as censored bars — the list itself keeps the secret.

HOW IT WORKS • Create your code. Add Face ID in one tap • Notes lock automatically when you switch apps • The app switcher shows only an opaque shield • Burn a note and it's gone — no trash, no undo • Everything stays on your device, protected by iOS file encryption

YOURS, PRIVATELY One purchase. Yours forever. No subscription, no account, no ads, no tracking. There is no server: your notes physically cannot leave your phone.
