Privacy Policy
Last updated: September 3, 2026
Overview
Real Concrete Calculator ("this site", "we") does not require an account, does not ask you to submit personal information to use any calculator, and does not run its own server-side database of user data. This page explains the little data that is collected, mainly through third-party services used to run and understand the site.
Calculator inputs
The dimensions, units, and options you enter into a calculator are processed entirely in your browser. When you use "Copy shareable link," those values are encoded into the page's URL — they are never sent to or stored on our servers. Closing the tab or clearing your browser history removes them.
Google Analytics
We use Google Analytics to understand overall traffic and which calculators are useful, so we can improve the site. Google Analytics uses cookies and collects information such as your approximate location, device and browser type, and pages visited. This data is processed by Google according to its ownprivacy policy. You can opt out of Google Analytics tracking across all websites using theGoogle Analytics Opt-out Browser Add-on, or by using your browser's tracking-protection or cookie settings.
Google Fonts
This site loads typefaces (Inter and IBM Plex Mono) from Google Fonts' servers. Loading a font this way sends your browser's IP address to Google as part of that standard web request, the same as loading an image from a third-party CDN. No cookies are set by this specifically.
Cookies
Aside from the cookies Google Analytics sets (see above), this site does not set its own cookies. You can block or delete cookies at any time through your browser settings; doing so will not affect the calculators' functionality, since they don't rely on cookies to work.
Children's privacy
This site is not directed at children under 13 and does not knowingly collect personal information from them.
Changes to this policy
If this policy changes — for example, if a new analytics or advertising service is added — this page will be updated and the "Last updated" date above will change accordingly.
