Privacy Policy

Information We Collect

ConcreteFree does not collect, store, or transmit any personal information. We do not require account registration, and we do not use cookies set by our own servers. The only data collection that occurs is through Vercel Analytics, which gathers anonymous, aggregate usage statistics as described below.

Vercel Analytics

This site uses Vercel Analytics to understand how visitors interact with the site in aggregate. Vercel Analytics collects anonymous page-view data such as page URL, referrer, browser type, and country — without any personally identifiable information (PII). Vercel Analytics does not use cookies set by ConcreteFree itself and does not fingerprint individual users. Data is aggregated and cannot be used to identify you personally.

For more information, see the Vercel Analytics Privacy Policy.

How We Use Information

The anonymous aggregate data provided by Vercel Analytics is used solely to understand which pages are most useful and to improve the site experience. We do not sell, share, or otherwise transfer any data to third parties for marketing or advertising purposes.

Third-Party Services

The only third-party service used by ConcreteFree is Vercel Analytics. No advertising networks, social media trackers, or other third-party scripts are loaded on this site.

Client-Side Processing

All concrete calculations performed on this site happen entirely within your browser using JavaScript. No input values (dimensions, quantities, costs, or any other data you enter into a calculator) are ever sent to our servers or stored anywhere outside of your browser session.

Children's Privacy

ConcreteFree is not directed at children under the age of 13. We do not knowingly collect any information from children. Because we collect no personal information from any user, there is no special risk associated with children using the site.

Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be reflected by updating the "Last updated" date at the top of this page. We encourage you to review this policy periodically.
