A cookie is a small file that stores internet settings. Almost every website uses cookie technology. It is downloaded by your internet browser on the first visit to a website. The next time this website is opened with the same user device, the cookie and the information stored in it is either sent back to the website that created it (first-party cookie) or sent to another website it belongs to (third-party cookie). This enables the website to detect that you have opened it previously with this browser and in some cases to vary the displayed content.
Some cookies are extremely useful, as they can improve the user experience on opening a website that you have already visited a number of times. Provided you use the same user device and the same browser as before, cookies remember for example your preferences, how you use a site, and adapt the displayed offerings to be more relevant to your personal interest and needs. Depending on their function and intended purpose, cookies can be divided into four categories*: Essential cookies, performance cookies, functional cookies, cookies for marketing purposes.
Depending on their function and intended purpose, cookies can be divided into four categories*: Essential cookies, performance cookies, functional cookies, cookies for marketing purposes.
Essential cookies are required so that you can navigate on a website and use its features. Without these cookies, functionalities cannot be ensured, for example that actions performed during a visit (e.g. text input or vehicle configuration) are preserved, also when navigating between individual pages of the website.
Functional cookies enable a website to save details that have already been provided (e.g. user name, your location) and to offer the user improved, more personal functions. Functional cookies are used, for example, to enable requested functions such as the playback of videos. These cookies collect anonymized information; they cannot track your movement on other websites.
Performance cookies collect information on how a website is used – for example which pages a visitor opens most frequently and whether they receive error messages from a page. These cookies do not save any information that permits identification of the user. The collected information is used for reports that are aggregated and anonymous. These cookies are used exclusively to improve the performance of a website and thus the user experience.
Cookies for marketing purposes are used to extract advertisements that are relevant to specific users and adapted to their interests. They are also used to limit the frequency of appearance of an advertisement and to measure the effectiveness of advertising campaigns. They register whether you have visited a website or not. This information can be shared with third parties, for example advertisers. Cookies to improve target group contact and advertising are often linked with page functionalities of third parties.
You can also block and delete cookies by changing your browser settings. To manage cookies, most browsers allow you to refuse or accept all cookies or only to accept certain types of cookie.
How you can manage and delete cookies can be found in the help function integrated in the browser. You will find more information for the most commonly used browsers below:
