About This Tool

A password-protected scratchpad that encrypts everything in your browser before it's sent, so the server only ever holds ciphertext it can't read. Share the board name and password through two separate channels so a single intercepted message can't expose both.

Frequently Asked Questions

Can you read what I paste?+
No. Your password never leaves your browser: content is encrypted with it before it's ever sent, so the server only ever holds ciphertext it can't decrypt. This is true end-to-end encryption, not just access control.
How do I share a board with specific people?+
Give them the board name and password through two separate channels. For example, send the link in a message and read the password aloud on a call. Anyone with both can read and edit; nobody without both can.
What happens if I forget the password?+
The content is unrecoverable. There's no password reset, because we never had the password or the plaintext to begin with; that's the tradeoff for genuine end-to-end encryption.
How long does a board last?+
You choose when saving: 5 minutes up to a maximum of 6 hours. It's held only in server memory, never written to disk, and is deleted automatically the moment it expires, or immediately if you hit Delete.
