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 by clearing this site's storage in your browser; the consent banner will reappear.
