Burn-after-reading Notes
Create a secret note that destroys itself after being read. Data is encrypted in your browser; the server can never read it.
Why the server can't read your note
Encryption happens in your browser: the text is locked with an AES-256 key generated on the spot, which is never sent to the server in full. The key lives in the link after the "#" character — and anything after "#" in a URL is never transmitted to the server over HTTP by design. Our database only ever holds ciphertext with no key attached — a meaningless block of bytes.
Why you can't view a note twice
The moment someone requests the content, the server returns it and permanently deletes the row in the same instant. Opening the same link again gets "Note not found" — that's not a limitation, it's the only way to guarantee exactly one person ever saw it.
What this is typically used for
Handing a new hire the Wi-Fi password, sharing account access, sending something that shouldn't sit in chat history forever — a messenger keeps messages for years, this disappears physically after a single view.
