Pro is unlocked with a licence key — there is no account and no password. Your charts stay in the browser; only the key and a random device id ever reach our server.
Activate a licence key
All slots used? Look up the key to see every activation and revoke one to free a slot.
No key yet? See Pro pricing.
Lost your key?
We only ever store a one-way hash of your key, so we cannot read it back to you. Enter the email you bought with and we will issue a fresh key for any licence still running and send it there. The old key stops working straight away.
