How it works
Install the app
Sign up with an email address. Your phone generates an encryption key pair and keeps the private key in its Keychain. It never leaves your device.
Send one invite link
Tap “Share Invite Link” and send it to the one person you want to talk to – partner, parent, friend. They install the app, tap the link, and you're paired.
Talk like nobody is listening
Every message is sealed with a key only your two phones can derive. Our servers only ever see ciphertext – that is a property of the design, not a promise.
What you get
- Encrypted text, photos, videos and files – even file names and sizes are encrypted
- Encrypted voice and video calls, sent directly between the two phones
- Real full-screen incoming calls with a ringtone, even when the phone is locked
- Disappearing messages, and unsend within two minutes – gone from both phones
- Safety code verification, so you can confirm nobody is in the middle
- Face ID lock, read receipts, typing indicators and 25 languages
What we can and cannot see
We cannot see
Your messages. Your photos, videos and files. Your calls – audio and video never touch our servers and are never recorded.
We can see
Which two accounts are paired, when a message was sent, and when a call started and ended. There are no ads, no trackers and no analytics SDK in the app.
Pricing
Text chat is free forever. Making voice and video calls needs a Secret Calls subscription with a free first month. Receiving calls is always free.
