Privacy Policy

Last updated: October 2026.

What we collect

Nothing that identifies you. There are no accounts, sign-ups or forms. The numbers you type into a calculator stay in your browser; they are never sent to us.

Analytics

We use cookie-free, privacy-friendly analytics (Cloudflare Web Analytics) to count page views. It doesn't set cookies or build a profile of you.

Affiliate links and ads

Some links go to retailers and brands that pay us a commission if you buy. When you click one, that site may set its own cookies to track the referral, under its own privacy policy. If we add display advertising later, the ad provider may use cookies; we will show a consent banner where the law requires it before that happens.
