These cookies are necessary for the website to function properly and for it to remember settings and preferences throughout a visit to the website, or until the next visit. Language settings or completed fields in a form, are examples of information the cookies help remember.

Matomo is a statistics service that is used on certain elements of this website to collect user statistics.

Google Analytics

We use this statistics service to keep track of how visitors use the website. Google might share this information with third parties if Google is legally required to do so, or if third parties process this information on behalf of Google. We do not allow Google to use the obtained information for other Google services.

The information that Google collects is anonymised as much as possible. The last part of IP addresses of visitors of this website is not saved. Therefore an IP address can only be traced back to a group of 256 persons. We implemented Google Analytics according to the roadmap of the Dutch DPA (in Dutch). The Dutch DPA is of the opinion that with these settings the information is still not fully anonymised and therefore Google Analytics is blocked if you reject cookies.

Cookies of third parties

In several places the website uses web content of other parties. For example, videos or images are embedded, or other sites can be opened through an iframe. There are also URLs that guide you to other websites. The web content of third parties could use cookies and will be blocked if you have rejected cookies.
