Privacy Policy

Concrete Calculator ("we", "our", "us") provides a free, in‑browser concrete estimation tool. This privacy policy explains what data we collect, how it is used, and your rights.

Data we collect

• Calculation data: All inputs you enter (dimensions, unit system, etc.) are processed locally in your browser. No values are sent to our servers.
• Essential cookies: A single session cookie is set to remember your unit preference and last‑used settings. It expires after 30 days and contains no personal information.
• Third‑party services: We embed Font Awesome icons and Google Analytics for aggregate usage statistics. These services may set their own cookies as described in their respective privacy policies.

Third‑Party Advertising (Google AdSense)

We use Google AdSense to display advertisements on the calculator page. Google, as a third-party vendor, uses 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 to you based on your visit to this site and/or other sites on the Internet.
• You may opt out of personalised advertising by visiting Google Ads Settings.
• Third-party vendors, including Google and DoubleClick, use cookies to serve ads. The DoubleClick cookie (set by doubleclick.net) tracks user interactions with ad creatives for measurement, attribution, and frequency capping.
• For more information about how Google uses data when you use our site, see Google's Privacy & Terms — Partner Sites.

• Under the General Data Protection Regulation (GDPR) and the Australian Privacy Act you have the right to access, correct, delete, or restrict processing of any personal data we may hold.
