Advertising, cookies, and consent
CivilKits includes Google AdSense site-connection metadata and loads the configured Google advertising script on substantive calculator/reference pages and the interactive homepage, not on navigation-only directories or site-information pages. Loading this third-party script can send request information to Google even if no advert is visibly displayed. Google and its partners may use cookies, web beacons, local storage, IP addresses, device identifiers and activity on this site for advertising delivery, measurement, fraud prevention or personalisation, depending on the account configuration, consent and applicable law. Third parties may place or read cookies in connection with advertising.
Script installation is not confirmation of site approval or actual ad serving. CivilKits does not currently claim to provide a tested on-site consent-management interface. Before enabling advertising, the publisher must configure the consent arrangements required by applicable law and Google, including Google's certified-platform requirements for personalised advertising in the EEA, UK and Switzerland. Browser settings or Google My Ad Center do not replace any required on-site consent process.
Read how Google uses information from sites that use its services, Google's advertising privacy information and Google My Ad Center.
