Privacy Policy

Calculandia respects your privacy. The values you type into our calculators are processed entirely in your browser — they are never sent to or stored on our servers.

Cookies and advertising

This site may display ads served by Google AdSense. Google and its partners may use cookies to serve ads based on your prior visits to this or other websites. You can opt out of personalized advertising in Google's Ads Settings (adssettings.google.com). We may also use privacy-friendly, aggregated analytics to understand which tools are most useful.

Your rights

Under data-protection laws such as the GDPR, the CCPA and Brazil's LGPD, you may request information about any personal data we process. Since our calculators require no registration and store no personal input, in practice such data is limited to standard technical logs and the cookie usage described above.
