🔥 Burn
Send a password or private note through a link that works once — then destroys itself.
Encrypted in your browser, so it is never readable by us.
Whoever opens the link first is the only person who will ever see the message — so send it somewhere only your recipient can read.
How it works
Your browser scrambles the note and creates a key. The plain text never leaves this tab.
The key sits after the #, which browsers never send to a server. We store only scrambled data.
Your recipient presses Reveal. The message is deleted from our server before it is even sent to them.
Open it again and there is nothing there. Unread links delete themselves when the timer runs out.
Questions
Can you read the secrets people send?
No. Your browser encrypts the message before it is sent, and the decryption key is placed in the part of the link after the # symbol. Browsers never transmit that part to a server, so we only ever store scrambled data we have no way to unlock.
What happens after someone opens the link?
The encrypted message is deleted from our server the instant it is claimed, before the reply is even sent back. Opening the link a second time shows nothing, and neither does anyone who finds it later.
Why is a password link safer than sending the password directly?
A password typed into email or chat stays in that conversation forever, gets backed up, and is readable by anyone who later gains access to either mailbox. A Burn link removes itself after one read, so an old message cannot leak a live password.
What if the link never gets opened?
It deletes itself when the expiry you chose runs out, whether or not anyone read it.
