Privacy Policy

Last updated: October 17, 2026

This policy explains what information HexaCalc (“we”, “us”) collects when you use hexacalc.com and how it is used.

Calculator inputs

All calculations run locally in your web browser. The values you type into our calculators are not transmitted to or stored on our servers.

Analytics

We use Google Analytics 4 to understand how visitors use the site (for example, which pages are viewed and for how long). Google Analytics uses cookies and similar technologies and collects information such as your approximate location, device, browser and pages visited. Learn more at How Google uses information from sites that use its services. You can opt out with the Google Analytics opt-out browser add-on.

Advertising

We use Google AdSense to show ads. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visits to this site and/or other sites on the Internet.

You may opt out of personalized advertising by visiting Google Ads Settings, or opt out of third-party vendors' use of cookies for personalized advertising at www.aboutads.info.

Server logs

Like most websites, our servers and our CDN (Cloudflare) automatically record technical data such as IP address, user agent and requested URL for security and reliability. These logs are kept for a limited time.

Your rights

Depending on where you live (for example California under the CCPA/CPRA, or the EU/UK under the GDPR), you may have rights to access, delete or object to the processing of your personal data. Because we do not hold personal data from calculator use, most requests concern analytics and advertising cookies, which you can control as described above. For any request, email [email protected].

Children

HexaCalc is a general-audience site. We do not knowingly collect personal information from children under 13.

Changes

We may update this policy. Changes take effect when posted on this page. See also our Terms of Use.
