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.

Google AdSense and advertising cookies

This site uses Google AdSense to display advertisements on selected tool pages. 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: Google uses cookies (including the DoubleClick DART cookie) to serve ads to you based on your visit to concrete-calcs.com and other sites on the internet. You may opt out of personalised advertising by visiting Google Ads Settings.
• Third-party ad vendors: Google's advertising partners (listed at Google's advertising technologies page) may also use cookies to serve relevant ads.
• Cookie types: AdSense may set the following cookies: __gads, __gpi, IDE, and others. These are used for ad delivery, frequency capping, and audience measurement.
• Your choices: You can control personalised advertising by visiting Google Ads Settings, AboutAds Choices, or by configuring your browser to refuse cookies. Note that opting out does not remove ads — it only makes them less relevant to your interests.

Your rights

• 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.
• Because we do not retain personal data from the calculator, requests can be directed to the contact form below.
