Privacy Policy

What data we collect

Calcilo.com's calculators run entirely in your browser. The numbers you enter (test scores, grades, salary figures, project dimensions) are never sent to our servers — they stay on your device and disappear when you close the tab.

Analytics

We may use privacy-respecting analytics to understand which pages are popular and to fix bugs. This data is aggregated and does not identify you personally.

Cookies

We use a local storage flag to remember your light/dark theme preference. We do not use tracking cookies for advertising.

Third-party links

Some pages link to external resources (such as further test-prep material). We are not responsible for the privacy practices of external sites.
