Type a password, message or note below. We encrypt it in your browser and give you a one-time link. The note is wiped the moment it's been opened the allowed number of times — or when it expires.
Your note is locked with AES-256 before it's sent. The decryption key lives only inside the link — it never reaches our server.
Choose how many times it can be opened and how many days it stays alive. Whichever limit hits first wins.
Once the open limit or expiry is reached, the encrypted note is permanently deleted from the server — not just hidden.
A one-time note is a message, password or secret you share as a special link that can only be opened a set number of times. After it's read — or after it expires — the note is permanently deleted, so it can never be seen again. It's the safe way to send something private over chat or email.
Yes — Secret Notes is 100% free, with no sign-up, no account and no limits. It's Australian-made and always free to use.
Your note is encrypted with AES-256 right inside your browser before it's sent. The decryption key lives only in the link and is never sent to our server, so the server only ever stores unreadable ciphertext. Not even we can read your notes.
Paste the password, choose how many times it can be opened, and press Create secret link. Send the link (or QR code) to the person. Once they open it the allowed number of times, it self-destructs — so the password can't be recovered by anyone later.
You decide. Set how many opens it allows (1 to 10) and how many days it stays alive (1 to 90 days). Whichever limit is reached first destroys the note. A classic one-time note burns the instant it's opened.
Yes. If you're after a free, self-destructing, burn-after-reading note tool, Secret Notes does exactly that — with end-to-end encryption and an optional QR code for the link.
