Privacy Policy

HSCalculadora is built to be private by architecture. The numbers you enter into any calculator are processed entirely in your browser. They are never sent to a server, never logged and never stored.

What we collect

We use privacy-conscious, aggregate analytics to understand which calculators are used and how the site performs. This measures page views and anonymous usage events — not the values you type into calculators. We do not use advertising cookies or sell data.

Your theme preference

If you switch between light and dark mode, that single preference is stored locally in your browser (localStorage) so the site remembers it on your next visit. It never leaves your device.
