Privacy policy

What we collect

We use Cloudflare Web Analytics to count page views. It doesn't use cookies and doesn't track you across sites. We see aggregate figures such as page views, referrers and country, not information about individual visitors.

Our calculators run entirely in your browser. Nothing you enter is sent to us.

If you email us, we keep your message so we can reply. We don't sell or share it.

Affiliate links

When you click an affiliate link, you leave our site. The vendor or affiliate network may set cookies to credit us for the referral. Their own privacy policies govern that.
