What it does
| Secret chats encrypted end to end with the Signal protocol. The server stores ciphertext it cannot read. |
| Text, photos, videos and voice messages, with read receipts, typing indicators, replies, editing and deleting for everyone. |
| Group chats with owners and admins, and a QR code any member can share. |
| Disappearing messages, blocking, and a list of every device signed in to your account. |
| Unlock with a fingerprint. The database on your phone is encrypted at rest. |
What it does not hide
Being straight about the edges matters more than sounding secure. A secret chat conceals what you said — not that you and someone are talking, when, or roughly how much. Group chats are protected in transit and stored on the server, which is stated inside the app on every screen where it applies.
