Self-destructing note
Need to send a password, account number or something private? Write it here and get a link to send. It's encrypted on your phone, opens once only, then it's gone for good — not even we can read it.
Link ready — send it:
The link works once. Don't open it yourself or it will be gone.
You have a secret note. It will be deleted as soon as you open it — be ready to read or copy it.
How it works
Your browser makes a random AES-256 key, encrypts the note and sends us only the ciphertext. The key stays after the # in the link, which browsers never send to servers. When the link is opened, the server hands over the ciphertext and deletes it in the same step, and the browser decrypts it.
How to use it
- Write the note and pick when it expires if unopened.
- Tap “Make link” and send it.
- It's deleted the moment it's opened — if someone else opened it first, you'll know.
Questions
Can you read my notes?
No. It's encrypted on your device with a key in the link's end (after #), which browsers never send to a server. We only see ciphertext.
Why a tap before opening?
So chat apps that preview links can't open and burn it by accident.
Lost the link?
It can't be recovered — by design. Make a new one.
