We don't ask for your name or any account. Calculators and tools on this site run in your browser: what you type into them is not sent to us.

Analytics and cookies

We count visits with Cloudflare Web Analytics, which uses no cookies and doesn't track you across sites.

If you accept cookies, we also use Google Analytics to see which pages are useful; it sets cookies for that. You can change your mind at any time with the "Cookie settings" link in the footer.

Affiliate links

When you follow an affiliate link, the seller may set its own cookie to record that you came from us. Their privacy policy applies on their site.
