Privacy Policy

Short because there is little to say.

What we collect

Nothing from the calculators. All computation happens locally in your browser; the numbers you enter never leave your device and are never transmitted to us or anyone else.

Server logs

Like any website, our hosting provider processes standard access logs (IP address, user agent, requested page) for security and performance, retained briefly under the provider's own terms.

Cookies and tracking

We do not set tracking cookies. Advertising partners may use cookies or similar technologies to measure ad delivery, subject to their own policies and applicable consent requirements. Our about page explains how the site is funded, and the methodology page covers what the calculators do with your inputs (nothing leaves the browser).

Data sharing

We have no user data to share, sell, or breach. Calculator inputs exist only in your browser tab.
