Zero-knowledge by design
Your keys are generated on-device and never leave it. We can't read your messages — even if we wanted to.
HUSHRequest access
v1.0 · invite-only beta
HUSH is an anonymous, end-to-end encrypted messaging platform for people who refuse to be a product. No phone number. No email. No ledger of who you are.
/ Architecture
Every message, file, and call is sealed on-device with keys we never touch. Our servers move ciphertext. That's it.
> generating x25519 keypair... [ok] > sealing message with recipient pub_key [ok] > uploading ciphertext 4.1kb [ok] > server view: ──── ──── ──── [opaque] > recipient unseal [ok]
/ Capabilities
Built to stand next to Signal, Telegram, Session — and outlast them on the one axis that matters.
Your keys are generated on-device and never leave it. We can't read your messages — even if we wanted to.
Create an account with a username and password. That's it. No SMS, no inbox, no identity to leak.
Set timers from 30 seconds to 24 hours. Messages erase from every device and every relay cache.
One-to-one calls with end-to-end encryption, noise suppression, and adaptive bitrate. Server-blind.
We strip what we can't encrypt. Push notifications never reveal sender or content.
Screenshot detection, screen-recording warnings, app lock, biometrics, and trusted-device review.
/ Sovereignty
At signup we generate a 24-word recovery phrase, show it once, and forget it forever. Write it down on paper. Lock it in a drawer. Without it, your account cannot be recovered — not by you, not by us, not by anyone.
HUSH does not back up chats to the cloud. If you lose your device and your phrase, your history is gone. That's the price of true privacy.
shown once · never transmitted
/ Manifesto
“Privacy isn't something you ask for.
It's something you take back.”
Modern messaging was built for advertisers. HUSH was built for sources, dissidents, founders, attorneys, lovers, friends — anyone who has ever felt watched. Anonymity isn't a feature. It's the entire product.

HUSH is rolling out by invitation. Reserve a username before someone else does.
