Send a note that burns after reading
Share passwords, keys and anything private as a one-time link. Your note is encrypted in your browser before it touches our server, and we never see what it says.
Someone sent you a private note
It was encrypted in the sender's browser. It is decrypted here, in yours, using the key in your link. We never see the key or what the note says.
0 / 100,000 characters
Encrypted in your browser. The key stays in the link and never reaches our server.
Your link is ready
Send it to the person who needs it. Anyone with the link can open the note.
Keep the whole link. The key is the part after the #. Without it nobody, including us, can read the note.
This note will be destroyed after the first view.
Expires:
This note has been destroyed. It was deleted from our server as you opened it, so copy anything you need before you leave this page.
Note unavailable
- Encrypted before it leaves your deviceAES-256-GCM with a fresh random key for every note.
- The key never reaches usIt lives in the link, after the #, which browsers don't send to servers.
- Gone when you say soBurn after the first view, or expire after 1 hour to 30 days.
- Encrypted in your browser
- Key never sent to our server
- Burn after reading

Three steps, and we only ever hold the locked box
You write
Type or paste your private content. A random encryption key is generated in your browser.
We store the ciphertext
Your note is encrypted with AES-256-GCM before it leaves your browser. Only the encrypted blob reaches our server. We never see the key.
They decrypt
The recipient opens your link. The key in the link decrypts the note in their browser. If you chose burn after reading, the note is then destroyed.
Why the key is in the link
The part of a web address after the # is called the fragment, and your browser never sends it to the server. It stays on your device. So the key that unlocks your note physically cannot reach us, even if our server were compromised.
This is the same approach used by PrivateBin and other zero-knowledge services.
What we store
- The encrypted note, which is unreadable without the key
- The initialisation vector, needed for decryption but useless on its own
- When the note expires, and whether it burns after reading
What we don't have
- What your note says
- The key, which only exists in the link
- A log of the IP addresses of people who open your notes
Decide how long it lives
Burn after reading
The note is permanently deleted from our server after the first person opens it. No second chance, no recovery, no undo. The ciphertext is gone.
Expiry
Every note expires after 1 hour, 24 hours, 7 days or 30 days, whether or not it has been read. Then the link stops working.
Up to 100,000 characters
Enough for passwords, recovery codes, private keys, config files or a long message. No account and no sign-up.

Your note is private. Is your connection?
Encrypted notes protect what you send. A VPN protects the connection you send it over, hiding your IP address and your browsing from your internet provider. PremierVPN is independent, UK-based and keeps no activity logs.
