Privacy Policy

Last updated: July 2026

Calculator data

Every calculator on this site runs entirely in your browser. Figures you enter — salary, weight, dates, dimensions or anything else — are never sent to a server, stored, or shared. Close the tab and the data is gone.

Cookies & local storage

We use your browser's local storage only to remember your light/dark theme preference. This stays on your device and is never transmitted anywhere.

Analytics

A future version of this site may use privacy-friendly, anonymised analytics to understand which calculators are most useful. No personally identifiable information would be collected.
