Privacy policy
Effective 2026-10-10. This policy explains what information the site collects, how it is used, and the choices you have.
Who we are
Concrete Calculator (concretecalculatorusa.com) is a free website offering concrete estimating tools and guides. Contact details are on the contact page.
Calculator inputs
The numbers you type into a calculator are processed in your browser. They are not sent to our servers, stored, or shared. Using the Copy button places the result on your own clipboard only.
Information collected automatically
Like most websites, our hosting provider records standard server logs, which may include your IP address, browser type, the pages requested and the time of the request. These logs are used to keep the site running and secure.
Analytics
We may use Google Analytics to understand which pages and calculators are used. Analytics collects information such as pages viewed, approximate location derived from IP address, device type and interactions such as a calculation being completed. It does not receive the measurements you enter. Where required by law, analytics runs only after you give consent through the banner shown on your first visit.
Advertising and cookies
The site is supported by advertising served by Google AdSense. Google and its partners use cookies and similar technologies to serve ads based on your prior visits to this and other websites, and to measure ad performance. You can opt out of personalised advertising at Google Ads Settings. Information about how Google uses data when you use partner sites is available at policies.google.com/technologies/partner-sites.
Visitors in the European Economic Area, the United Kingdom and Switzerland are asked for consent before advertising cookies are set, through a Google-certified consent management platform. Visitors in US states with privacy laws can exercise opt-out rights through the same mechanism or the controls below.
Cookies currently used or planned:
