Hold the button and talk. The other person hears it once — then it's gone, from their screen, your phone, and our servers. Nothing is stored. Nothing is left to breach.
See it in action
A voice message that plays once and then destroys itself. Here's the whole lifecycle — and the screens you'll actually use.
Why Vanish
Most "secure" apps still keep a copy of your conversations somewhere — and that copy is exactly what gets stolen, leaked, or exposed. Vanish is built the opposite way.
Only you and the person you're talking to can hear it. Built on the same protocols that secure Signal — the Double Ratchet and X3DH — over audited cryptography.
No history, no recordings, no database of conversations. Undelivered notes live in memory for minutes, then vanish. There is nothing to hack, seize, or subpoena.
Every message uses a fresh key that's thrown away after use. Steal a device tomorrow and yesterday's messages stay locked.
Everyone's public keys are anchored on-chain, so no one — not even us — can secretly swap in a fake key to eavesdrop. Provable, not just promised.
Dead simple
Open the link and Add to Home Screen. No app store, no phone number, no account.
Your keys are generated on your device and never leave it. The handle is your identity.
Add a contact by handle, hold the button, and speak. They play it once — then it's gone.
Who it's for
Straight talk
No one can honestly promise that. What we promise is concrete and verifiable: a fully compromised Vanish server yields nothing readable, key-swap eavesdropping is detectable and anchored on a public blockchain, and every message is forward-secret. Trust the math, not the marketing.
Deployment
Use it today — nothing to set up. Just open the app.
Run the relay entirely inside your own environment.
Your brand, your users, your infrastructure.
Encrypted, ephemeral, on-chain-verifiable communications — free to try, right now.
