3. Cookies & Tracking Technologies

ConcreteToolkit.com uses cookies and similar technologies to operate the site and understand how visitors use it. Here is a breakdown of what we use:

Essential Cookies

These are required for the site to function. They do not track you across other websites and cannot be disabled without breaking site functionality.

We use Google Analytics to understand how visitors interact with our pages — which calculators are most used, which states are most popular, and how traffic arrives. Google Analytics collects anonymized, aggregated data. We have enabled IP anonymization. You can opt out of Google Analytics tracking by installing the Google Analytics Opt-Out Browser Add-On.

We display ads through Google AdSense. Google may use cookies to serve ads based on your prior visits to our site or other websites. See Section 4 for more details and how to control ad personalization.

4. Advertising

ConcreteToolkit.com is free to use and supported by advertising. We use Google AdSense to display ads on our pages. Google AdSense may use cookies and web beacons to serve ads based on your interests and prior browsing behavior.

• Google uses the DoubleClick cookie to serve interest-based ads across the web.
• You can opt out of personalized ads through Google's Ads Settings.
• You can also opt out via the Network Advertising Initiative opt-out page.
• For California residents, see Section 7 (Your Rights) for CCPA opt-out options.
