Privacy Policy

Last updated: October 2026

What we collect

Almost nothing. Our calculators run 100% in your browser — the numbers you type into them are processed on your device and never sent to our servers. We don’t ask you to sign up, and we don’t sell data because we don’t have your data to sell.

What we do collect

Like most websites, we may use basic, privacy-friendly analytics to see which pages get visited (page views, referrers, device type). This data is aggregated and can’t identify you personally.

Cookies

We don’t set advertising or tracking cookies. If we add comments or contact forms later, this policy will be updated.
