What the site collects
The site does not use cookies, advertising or analytics at the moment. The calculator runs in your browser. The numbers you type stay on your device and are not sent to a server. They are written into the page address so you can bookmark or share a setup, which means anyone you send that link to will see those numbers.
Hosting
The site is hosted on Cloudflare Pages. Cloudflare may process technical data such as IP addresses and requested pages to deliver and protect the service. See Cloudflare's privacy policy.
The site has no forms and collects no email addresses. A contact address will be added later. When it is, messages and addresses will be used only to reply, will not be sold, and will be deleted within 12 months.
Changes
If analytics, affiliate links or ads are added, this page will be updated first.
