Vanish
Share a password or private note as a link that works once, then disappears. It's encrypted in your browser — the key lives in the link, never on our servers, so we can't read it.
Encrypted in your browser. The link is the only key — we never see it.
How it works
Your secret is scrambled on your device before anything leaves it. The key sits in the link's #fragment, which browsers never send to a server — so we store bytes we can't read.
Opening the link hands over the encrypted bytes and deletes them in the same step. A second visit finds nothing. Link previews don't burn it — only an actual click does.
No sign-up, and we keep no sender identity. Add a passphrase (shared separately) and a secret needs both the link and that word — something even we could never provide.
Questions
The secret is encrypted in your browser before anything is sent. The key that decrypts it lives in the part of the link after the # — which browsers never send to a server. So we only ever store scrambled bytes we have no way to unscramble. Not a promise; it's how it's built.
The first time someone opens the link and clicks Reveal, we hand over the encrypted bytes and delete them in the same step. Open the same link again and there's nothing left — it shows “this secret is gone.” It can be viewed exactly once.
No. Just loading the page doesn't consume the secret — only clicking Reveal does. Link-preview bots load the page but don't click, so the secret survives for the real recipient.
For anything truly sensitive, yes. A passphrase means the secret needs both the link and a word only you and the recipient know — send the passphrase over a different channel (say it on a call). Even someone who intercepts the link can't open it.
Yes — create and share one-time secrets for free, no sign-up. A developer API and extras like notify-on-read come later.
Whoever has the full link can open it once — so share it over a channel only the recipient controls, and use a passphrase for extra safety. Secrets also expire on the timer you pick, whichever comes first.
