A cookie is a small text file that stores Internet settings. Almost every website uses cookie technology. The cookie is downloaded by your Internet browser the first time you visit a website. The next time you visit this website from the same device, the cookie and the information in it are either sent back to the originating website (first-party cookies) or to another website to which it belongs (third-party cookies). By that, the website can detect that it has already been opened using this browser, and in some cases, it will then vary the content it shows.
Some cookies are extremely useful because they can improve your user experience when you return to a website you have already visited. This assumes that you are using the same device and the same browser as before; if so, cookies will remember your preferences, will know how you use the website, and will adapt the content you are shown so that it is more relevant to your personal interests and needs.

Cookies on this website that do not require approval.
Cookies that are essential, also known as 'strictly necessary' cookies, enable features without which you would not be able to use the website as intended. These cookies are used exclusively by this website and are therefore known as first-party cookies. They are only saved on your computer while you are actually browsing the website. An example of why strictly necessary cookies are used is to ensure that what you see on screen corresponds to the data volume which your current Internet connection can handle. Another example of what these cookies do is facilitate a switch from http to https when you change pages, so that the security of data transmitted is maintained. Furthermore, a cookie of this kind is used to store your decision about the use of cookies on our website. Your consent is not required for the use of strictly necessary cookies.
First-party cookies on this website that require consent
Cookies which, in strictly legal terms, are not absolutely essential in order to use this website, do nevertheless fulfill important functions. Without these cookies, features that enable our website to be used easily, such as pre-completed forms, will no longer be available. Settings you make, such as language choices, will no longer be saved, so you will be asked about them every time you change pages. As well as that, we will no longer have a way of presenting offers to you that are tailored to you personally.
