Many internet users prefer to prevent tracking when browsing. Tracking has its good and bad sides. However, according to many data protectionists, the latter dominates. Among other things, tracking cookies can help to significantly improve the user experience when browsing the internet, for example by retrieving stored information when a website is visited again. Tracking data can also be used to identify possible errors on a website and thus improve the user experience. However, tracking cookies also have their downside. Data can be collected by third parties without you as a website visitor being aware of it. This data can then be used for advertising purposes or shared with other companies.
