Your System Audit · Private access

Begin with your license.

Your purchase includes a license key in the Gumroad receipt and product content page. Enter it here to open the private, device-local audit.

OYS sends the key to Gumroad for verification and does not place it in localStorage, analytics, or application logs. Successful access is remembered with a secure, HttpOnly session cookie.

If the key does not work, or the receipt never arrived, write to support@oys.systems.
