Security
Security that feels invisible.
Watfoe uses industry‑standard encryption so only you and your contacts can read messages.
End-to-end encryption keeps chats private.
Keys rotate often to protect past messages.
Verification steps help prevent impersonation.
X3DH
X3DH starts a secure session even when someone is offline by using identity keys and one‑time prekeys.
Double Ratchet
Double Ratchet updates encryption keys after every message, keeping past chats safe if a device is compromised later.
What this protects
- Message content and attachments.
- Past conversations, even after a breach.
- Sessions that heal once an attacker is removed.
Threat model
We design for hostile networks, curious infrastructure, and temporary device compromise.
We can’t protect chats if a device stays fully compromised, so safety checks still matter.
This is a high-level overview. More details will be shared later.
