Share encrypted, one-time notes.
Your note is encrypted before it ever leaves your browser — not even we can read it.
Your link is ready
Share this link over a secure channel. If it's one-time, it will be destroyed after the first person opens it.

Notes I've sent
This list is stored only in this browser — only the note ID and expiry date are kept, the decryption key is NEVER saved. So not even you can open the content from this list.
Note to the Future
Write it today, let it open on the date you choose — up to 5 years with the Time Capsule.
Frequently asked questions
Is the encryption key ever sent to the server?
No. The key travels in the # (fragment) part of the link, which browsers never send to the server. Our servers only ever store the encrypted text — and without the key, it cannot be decrypted.
Who can read my note?
Only people who have the complete link, key included. Server administrators, the hosting provider, and any third parties cannot read your content; all they hold is meaningless encrypted data.
How long are notes kept?
When you create a note, you choose a lifetime between 1 hour and 30 days. Once that time is up, the note is automatically deleted from the server. One-time notes are permanently destroyed the moment they are first viewed.
Why should I trust this tool?
Encryption happens entirely in your browser using the standard WebCrypto API (AES-GCM 256-bit). You can inspect the page's source code and confirm in the network tab that only encrypted data ever leaves your device.
