Privacy Policy

Last updated: 2026

What we collect

The numbers and ingredients you enter into our calculators are processed entirely in your browser. They are never transmitted to us, stored by us, or shared with anyone.

Our hosting provider keeps standard, short-lived server logs (IP address, browser type, pages requested) to operate and secure the service, as virtually every website does.

Advertising

This site may display ads served by third-party advertising partners such as Google AdSense. Ad providers may use cookies or similar technologies to serve ads based on your visits to this and other websites. You can opt out of personalized advertising from Google at Google Ads Settings. Where required by law (for example in the EEA and UK), you will be asked for consent before any advertising cookies are set.

Analytics

If we use analytics, it will be privacy-respecting aggregate measurement (page views, referrers) rather than individual tracking. We do not build profiles of visitors.

Your choices

You can use every tool on this site with cookies disabled — the calculators don't need them. Browser extensions that block ads or trackers will not break any functionality.

Changes

If this policy changes, the new version will be posted on this page with an updated date.
