What I collect

Calculator and converter inputs: nothing. Conversion and calculation run entirely in your browser. I do not see, store, or track the numbers you type.

Feedback form: if you submit the feedback form, I receive what you wrote (your message, feedback type, and any optional name or page you included) through Google Forms. I use it only to fix bugs and improve the site.

Cookies and analytics

This site uses Google Analytics (GA4) to understand how visitors use the site — for example, which pages are visited and which tools are used. Google Analytics uses cookies and may collect anonymized usage data, including approximate location and device information. I do not see your name, email, or the numbers you type into the converter. You can opt out with the Google Analytics Opt-out Browser Add-on or by blocking cookies in your browser. The calculator itself works without cookies.

Third parties

The site is hosted on Cloudflare Pages. The feedback form is provided by Google Forms and subject to Google's policies.

Changes

If this policy changes, I will update the date above and note what changed.
