Privacy policy

This site sets no cookies of its own and asks for no personal information.

Traffic is measured with a cookieless analytics script that records page views and referrers in aggregate. It does not identify visitors and does not follow them between sites.

When advertising is enabled, the advertising network sets its own cookies, and in regions where consent is required the advertising script does not load until consent is given. The network's own privacy policy governs what it collects.

Nothing you type into a calculator leaves your browser. The figures are worked out on the page.
