What are cookies used for? 

This website uses cookies. A cookie is a small data file placed on your computer, tablet or mobile phone while visiting a website. This file stores data such as preferred settings, order data or visitor information. 

The use of these cookies is necessary to reinforce the legitimate interests of Kadaster and website visitors. Cookies help to provide a well-functioning website. We provide more information about the cookies we use below.

Analytical cookies to understand web statistics 

We use analytical cookies to better understand how our website functions. Google Analytics, Piwik and Siteimprove help us understand key statistics on our visitors’ user experience. We analyse this data, which allows us to tailor the website to visitors even better. 

Google Analytics was set up by Kadaster in accordance with the Personal Data Authority’s Guide on the privacy-friendly setup of Google Analytics. This means that the following steps have been taken: 

  1. Kadaster has concluded a processing contract with Google. 

  1. Kadaster has set up privacy-friendly Google Analytics, which means that the information is kept anonymous as often as possible. The IP address consists of 4 octets of 3 digits each. Kadaster has chosen to mask the last octet of the IP address. 

  1. In the standard Google Analytics settings, Kadaster has unselected the ‘share data with Google’ option. This means that the collected information is not shared with Google or others. Moreover, Kadaster has not given Google permission to use the obtained information for other Google services. 

  1. Kadaster informs its website visitors about the use of Google Analytics. 

Piwik and Siteimprove are set to assign a randomly generated identifier (ID) to generate statistics. The masked IP address is shown to Kadaster as a generated identifier. As a result, visitors are completely anonymous and are only known to Kadaster as ID numbers.

No information that is traceable to the user is transmitted by Piwik or Siteimprove. By using these settings, the consent of website visitors is not required to use these analytical cookies. 

Examples of data we collect: the number of website visitors, how visitors arrived on our website and the pages they visited on our website.
