Early build. The encryption and the storage are real — Argon2id, XChaCha20-Poly1305, and a database that only ever holds sealed bytes. It has had no independent security review, so treat it as something to try rather than somewhere to keep what you cannot lose.

Rooms

How this is encrypted →
No account, no email

Twelve words are the whole account.

A room is a private message board that exists only for the people holding its twelve-word key. Messages are encrypted in your browser before they reach us, so what we store is an anonymous identifier and a pile of noise — no room name, no key, no way to read a conversation, and no way to get you back into one if the words are lost.

Open a room

Enter the twelve words. They are the address and the key at once, so there is nothing else to supply.

Create a room

We generate twelve words with the browser's cryptographic random number generator and show them to you once. We never receive them, and we cannot help you recover them.
