lost your key?
get it again
Enter the e-mail address you paid with and your Pro key is sent there again. It is only ever sent to the address that bought it.
New computer? You do not need this page - paste the key you already have into Settings → License there. One key covers one computer at a time, and there is nothing to transfer.
The address no longer exists? Write to hello@owntools.app with the order number from Polar’s receipt.
