What is a cookie ?

A cookie is a small text file that can be stored on your computer when you visit websites. Information is saved in this text file, such as your choice of language on a website. When you visit the website later again, this cookie returns to the concerned website. In this way, the website recognizes your browser and can for example retain your choice of language.

Cookies usually also have an expiration date. For example, some cookies are automatically deleted when you close your browser (so-called session cookies), while others can be stored longer on your computer, sometimes until you delete them manually (so-called permanent cookies).

Why we use cookies ?

The Authority, administrator of this website, uses 2 types of cookies on

  1. Cookies for functional purposes ;
  2. Cookies for analytical purposes.

The Authority uses Drupal to keep the content of our website up-to-date. This software uses functional cookies. This means that these cookies are essential to the proper functioning of this website. It is not possible to refuse these cookies if you want to visit our website.

The Authority also uses MATOMO for analytical purposes. This analytical tool installs cookies that we use in order to quantify the visits (traffic) on the website. This allows us to know how many times a particular page has been consulted. We use this information only to improve the content of our website or as a basis for a new campaign by determining certain topics of great interest.

This analytical tool is installed on our own servers. This concerns therefore "first party" cookies (direct cookies). This means that we completely control the information collected through these cookies. No data are sent to third parties. Therefore, we can guarantee that this information will not be used for other purposes. The use of these "first party" cookies for analytical purposes is subject to your prior consent. Thus, you can refuse the installation of these cookies on your device.
