Calculator data
Everything you enter in our calculators is processed in your browser. Your answers are not sent to or stored on our servers. If you use "Copy link to my result", your answers are encoded in the link itself, after the "#" — browsers do not send that part of a link to any server, but anyone you share the link with can see your answers.
Analytics
We use Google Analytics to understand which pages are useful and whether the calculator is being used. Google Analytics sets cookies and collects usage data such as pages viewed, approximate location, device and browser. We only send event names (for example "calculator used" or "result link copied") — never your answers or your score. You can opt out with the Google Analytics opt-out add-on or by blocking cookies in your browser. The embeddable draw widget does not use analytics or cookies.
Advertising
We may show ads served by Google AdSense. Google and its partners may use cookies to serve ads based on your visits to this and other websites. You can opt out of personalized advertising at Google Ads Settings. Where required, you will be asked for consent first.
Hosting
The site is hosted on Cloudflare, which processes standard request data (such as IP address) to deliver and protect the website.
