Calculator inputs are processed in your browser. This site does not include third-party analytics, advertising scripts or externally loaded fonts.

Saved favourites

When you save a calculator, its identifier is stored in your browser’s local storage. This keeps your favourites available on this device. Use the save button again to remove a favourite. No calculator inputs are stored with favourites.

Share links

“Share inputs” places the current inputs in the URL and copies that URL to your clipboard. Anyone with the link can read the inputs. URLs may be recorded in browser history and hosting logs. Avoid sharing sensitive personal, medical or financial details. Keep scenario comparisons stay in page memory and disappear when you reload.

Hosting

The hosting provider may process technical request information, including an IP address, timestamp and requested URL, to deliver the site. Calculator inputs are not sent by a calculation request; opening a share link does send the URL to the hosting provider.
