What are cookies?

Cookies are small files that websites put on your computer’s hard disk when you visit them for the first time.

The cookie contains a unique code that enables your browser to be identified when you visit the website (“session cookie”) or on future repeat visits (“permanent cookie”). Cookies can be installed by the server of the website that you are visiting or by partners that this website cooperates with. The website’s server can only read cookies that it has installed itself. It does not have access to any other information on your computer or on your mobile device. Cookies are stored on your computer or mobile device in your browser’s directory. The content of a cookie is usually the name of the server that installed the cookie, an expiry date and a unique number code.

Important: cookies are completely harmless. They do not delete any data from your computer, they do not change any file or program and cannot contain any virus.

What are cookies used for?

With a cookie, our website can recognise you whilst preserving your anonymity. The website recognises your preferences and automatically adapts itself to them. But this information is not linked to your name or identity in any way. So, for example, these cookies enable you to surf directly in your own language so you do not have to fill in your connection data every time. In other words, they make using this website much faster and more user-friendly.

Cookies can help you to be more efficient. Have you ever put an item in your virtual basket in an on-line store and returned there a few days later and found that the item is still there? This is an example of how cookies work.

Cookies can also be used to make the content of a website or the advertising shown there more relevant for the person visiting and can adapt the website to their personal tastes and requirements.
