Raven — Hidden Messages

Early release. Hide the water in the river: seal a secret inside an ordinary post. No account, no phone number, just keys.

Hidden messages in plain sight.

Raven is a cryptographic tool that hides sealed secrets inside ordinary text. Write something private, seal it for one specific person, and Raven hands you back a normal-looking sentence — a caption, a comment, a text — that quietly carries the route to your secret. Post it anywhere. To everyone else, it's just a post. To the person with the right key, it's a doorway.

WHY RAVEN IS DIFFERENT Most private tools protect what you say. But anyone watching can still see THAT you're talking — and who you talk to, when, and how often becomes a kind of message in itself. Raven doesn't show up on that map. There's no traffic between you and your recipient at all — just a public post that happens to mean something to one person.

NO ACCOUNTS, NOTHING TO LEAK

• No signup, no email, no phone number, no name.
• Your keys are generated on your device and live in the iOS Keychain, behind Face ID or your passcode.
• Your secrets are sealed on your device with end-to-end encryption before anything touches a network.
• No analytics, no tracking, no ads. We couldn't read your ravens if we wanted to — there's no place in the system where that information exists.

HOW IT WORKS

1. Add the key of the person you want to reach — scan their QR code or paste their key.
2. Write your secret and seal it into an ordinary carrier sentence.
3. Post or send the carrier anywhere you already talk.
4. They scan it in Raven and the secret unseals on their device — where only they can see it.

A NOTE ON HONESTY, BECAUSE IT'S EARLY Raven is young and improving fast. It currently runs on a test network, and message availability may change during network upgrades. Ravens are ephemeral by design — the retrievable copy is cleared after a limited window, so Raven is not an archive and makes no durability promises. Keep your own copy of anything you need to keep. And there is no password recovery: your keys exist only on your device, so export a backup. If you lose both, no one — including us — can recover them.

ZERO TOLERANCE Raven is for lawful communication between consenting people. Our Terms state zero tolerance for objectionable content or abusive behavior. You can block any key, dismiss any raven, and report abuse from inside the app — reports go to a monitored inbox and we act within 24 hours.
