Privacy
This calculator works in your browser. It does not send score inputs to a server.
Scores you enter
Section scores stay in the current page’s memory while the calculator is open. They are not written to the URL, saved to an account, or sent to this site. Refreshing the page clears them.
Analytics
Google Analytics 4 is optional. The Google tag does not load until you choose “Allow analytics”; choosing “No thanks” keeps it disabled. If enabled, we send page views and calculator events with the page path, selected test version, or validation error type. Page paths exclude query strings and fragments. Google may also process standard browser, device, and session metadata to provide analytics. Section scores and other score inputs are never sent. Google Signals and ad personalization are disabled. The choice is saved in this browser’s local storage and can be changed with “Privacy settings” in the footer. If you allow analytics, Google Analytics may use cookies such as _ga to distinguish browsers for usage reporting; choosing “No thanks” disables the tag and clears its analytics cookies for this site.
