The calculators run entirely in your browser. Numbers you type are not sent to us or stored by us. This site sets no cookies, has no accounts, no forms that submit data, no ads and no analytics.

Our host, Cloudflare, processes standard request data (such as IP address) to deliver and protect the site, under its own privacy policy.

If this changes (for example, if we add analytics or ads), we will update this page first.
