Privacy Policy

This site uses Google Analytics 4 to understand how visitors use the guides and tools. Analytics is optional and loads only if you choose “Allow analytics” in the privacy prompt. If you choose “No thanks,” or have not made a choice, the Analytics tag does not load.

When enabled, Google Analytics may collect page views, interactions, browser and device information, and general location information. We use these reports to improve the site. We do not use Analytics for advertising or intentionally send information that directly identifies you. Google processes data under its privacy and partner-site terms.

Your analytics choice is saved in this browser’s local storage. Use “Cookie settings” in the footer to change it. Clearing this site’s stored data also resets your choice. Calculator entries are processed in your browser and are not sent to us. Our hosting provider may process standard server logs when you visit.
