Cookie Policy

We use a small number of cookies and similar technologies, grouped into four categories.

• Strictly necessary — required for the site to work (e.g. saving your consent choice). Always on.
• Analytics — anonymous traffic measurement so we can improve calculators. Off by default.
• Advertising — used by ad partners such as Google AdSense to show relevant ads. Off by default.
• Affiliate tracking — measures clicks on partner links so we can keep the site free. Off by default.

You can change your choices any time on our Your Privacy Choices page, or by clearing this site's storage in your browser (the consent banner will reappear).
