Send a secret that can only be read once.
Free to use. Private by design.
Paste a password, a key, or a private note. You get a link. The link opens once, then the secret is gone. Nothing you type is ever sent to this site unencrypted, and the key that unlocks it never leaves your browser.
Your link
- Opens
- once
- Expires
The link is the secret. Anyone who has it can open it, and once they do, it is gone. Send it only to the person it is for, through a channel you trust, and tell them separately to expect it.
Do not use this for
- Anything the recipient needs to keep. Share a vault in a password manager instead.
- Credentials you could not rotate if something went wrong.
- Identity documents, medical records, or anything whose exposure you could not undo.
- Sending to an address or number you have not confirmed. The link is the secret.
- Anything that needs an audit trail. There is none, by design.
What happens
Your browser makes up a random key and encrypts the text with it. Only the scrambled result goes to this site, where it waits behind a random address. The key rides along in the link, after the #, which browsers never send to any server. Whoever opens the link presses a button, the scrambled text is released exactly once and deleted, and their browser unlocks it with the key. The full picture, including what this does not protect against.
