Privacy

The calculator runs entirely in your browser. What you pick is kept in the page address so you can share or bookmark it; it is not sent to us.

Our web server and our network provider (Cloudflare) keep standard access logs (address, page, time, browser) to keep the site running and to count visits. We also use Cloudflare Web Analytics, which counts page views without cookies, and Google Analytics 4, which sets cookies to count visitors and see which pages and tools are used. Google Analytics is not loaded if your browser sends Do Not Track or Global Privacy Control. We do not use advertising cookies, build profiles of you or sell data.

Stores you visit through our links have their own privacy policies.
