Use of cookies

As data protection is so important and we are committed to being transparent, you will find some information below about the cookies used on our website. Furthermore, you will be informed on how to disable cookies, if you do not wish to enjoy the benefits they offer.

1. What are cookies?

Cookies are small text files that are stored on your device (computer, tablet or smartphone) when you visit a website. They enable the website to identify your device as you click through its pages and if you return at a later point. This makes it easier for you to use the website and personalize the content.

The following terms will help you to understand and manage cookies:

First-party cookies

Cookies that are installed on your device by the organization operating the website are called “first-party cookies”.

Third-party cookies

Cookies that are installed on your device by the website you visit are called “third-party cookies”. This could be a cookie installed by a web analytics company to provide the website operator with information about the number of visitors to its website.

Persistent cookies

“Persistent cookies” remain on your device, even if you close your internet browser. They are activated every time you visit the website that generated that particular cookie. For example, if a website uses a persistent cookie to remember your login credentials, you will not need to enter them again every time you visit that website..

Session cookies

“Session cookies”, on the other hand, are not stored permanently and are normally used to operate a website, e.g. by allowing a user to switch from one page to the next without having to log in again. All session cookies are deleted from your computer once you close your browser.

Flash cookies

“Flash cookies” are installed by websites containing media (e.g. video clips). This also requires Adobe Flash software. These allow content accessed from your device to be downloaded more quickly and information to be stored.
