The short version

CalcHeadquarters does not collect, store, or sell your personal data. All calculations run entirely in your browser. Nothing you enter into any calculator is sent to our servers.

Analytics

We use Google Analytics 4 to understand how visitors use the site — which pages are visited, how long people stay, and which calculators are most popular. Google Analytics uses cookies and collects anonymized usage data. It does not collect any information you enter into our calculators.

You can opt out of Google Analytics by installing the Google Analytics Opt-out Browser Add-on.

What we don't do

• We don't require accounts or sign-ups
• We don't collect email addresses
• We don't sell or share data with third parties
• We don't use advertising trackers
• We don't store any calculator inputs or results

Cookies

The only cookies on this site are set by Google Analytics for anonymous traffic measurement. No first-party cookies are used.

We use Google Fonts for typography and Google Analytics for traffic measurement. Both are loaded from Google's CDN. No other third-party services are used.
