Anonymous encrypted chat
A direct, end-to-end-encrypted conversation between two people. No account, no history, nothing stored. Open a room, share the code out of band, and talk.
SICH vs Signal
For anonymous, leave-no-trace conversations
Signal
- Requires a phone number — tied to your real identity
- Must install an app — leaves traces on your device and app-store account
- Has an account on a server — the service knows you exist and when you're online
- Chat history is stored on the device
- Your identity is linked through your phone number
SICH
- Zero identity — no phone number, no email, no name
- Nothing to install — just open a web page
- No account — the server doesn't even know you exist
- Nothing is stored — close the tab and it's as if the chat never happened
- End-to-end encrypted (X25519 + AES-256-GCM), new ephemeral keys every session
- One-tap “Wipe everything” + auto-close when idle
- Emoji verification proves no one intercepted your keys
Stay safeSecurity tips
- Share the room code through a different channel than the one you'll talk on — ideally in person.
- Always verify the emoji together. That check is what guarantees no one is sitting in the middle.
- For maximum anonymity, connect over Tor or a VPN so the network can't see that two devices talked.
- When you're done, hit Wipe or just close the tab — nothing is left behind.
- No account, no phone number, no app — nothing here ties this conversation to you.
Honest answers
Do messages really disappear?
Yes. Messages live only in your browser tab's memory — never saved anywhere: no server, no database, no disk. The moment you close the tab, hit 'Wipe everything', or the session times out, they're gone for good, because there's nothing left to recover from — they no longer exist anywhere. The only way to see a message is to be looking at the screen while the chat is open — just like any app, whatever is on screen is visible to someone physically holding your unlocked device at that moment. That's not 'recovering deleted data' (impossible here) — it's simply reading what's on an open screen. Close the chat and there's nothing to find.
What about metadata?
When two browsers connect, the internet itself must route the connection — so for a brief moment our matchmaking server sees that two IP addresses are connecting. It never sees WHO you are or WHAT you say — only that a connection is being set up — and it keeps none of it: no logs, no IPs stored, nothing written to disk. The server only introduces the two browsers to each other, then it's out of the loop — messages flow directly browser-to-browser, never through it. This is how the internet works, not a weakness unique to us; every online service routes connections. The difference: we keep zero record of it.
