Desktop activation: After purchase, create and verify a Thaddeus website account with the same checkout email. Sign in on the website to reveal the separate license activation key once, save it securely, then enter that key in Thaddeus Desktop. The desktop never asks for your website email or password, and the key is not emailed.
The stable download URL always selects the newest signed Apple Silicon build. Windows remains unavailable until Delphi Labs publisher signing is verified.
