What are cookies?

This website could make use of cookies. Cookies are text files that are stored on your computer or mobile device when you visit a website. They contain small amounts of information. By means of cookies we can recognise a computer or mobile device on return visits.

Cookies are often used to personalise websites and enhance the user experience. Cookies allow us to (temporarily) store preferences for example, and record the choices you have made. We also use cookies to see which web pages people have visited and to measure how effective advertisements and searches are. In addition, cookies also provide us with insight into the surfing behaviour of users, so that we can improve our websites, communication and products.

It is also possible that so-called "web beacons" are used. These are images which are normally not visible to the user. Just as cookies, these "web beacons" can be used to follow the surfing behaviour of users. We can also use "web beacons" for HTML e-mailing (not in plain text therefore) that we send. In this way we are able to see whether an email has been opened for example and whether particular links have been clicked.
