Privacy Policy

We do not collect personal information. The Concrete Calculator requires no account, no sign-up, and no personal details — calculator inputs are processed in your browser and never saved on a server.

If you accept analytics cookies, we use Google Analytics and Microsoft Clarity to understand aggregate traffic, device types, page usage, heatmaps, and session replay. We use this data to improve the calculator and site usability. Google Analytics is configured to anonymize IP addresses.

You can decline analytics cookies and still use the site. Internal IP exclusion must be configured in the Google Analytics admin settings if needed. Google AdSense may be used later for advertising. We do not sell your data. Questions can be sent to [email protected].
