On websites, cookies are ubiquitous and often essential for the smooth functioning of these websites. These small text files store important information about your activities and preferences, enable personalized experiences, and help the website operator analyze your behavior on the website. In this article, you will learn how to delete, block and manage cookies in Chrome, Firefox, Safari and Edge on your Mac, Windows PC, iPhone or Android smartphone.<\/span><\/p>\n<\/div><\/div>

We must point out that the following statements do not constitute legal advice. Therefore, we can only give you evaluations from our intensive experience with the EU legal regulations in practice and a technical assessment of the situation.<\/p>\n<\/div><\/div><\/div>

What are cookies and how do they work?<\/h2>\n

Cookies are small text files that store information on your device and can be read by the website when required. They perform various functions, ranging from ensuring basic website functionalities to collecting and analyzing user data. It is important to differentiate between technically necessary and technically unnecessary cookies.<\/span><\/p>\n

Technically necessary cookies<\/b> are essential for the proper functioning of the website. They store information that is absolutely necessary for the use of the website. A classic example of this is the storage of your login status on a website, as otherwise you would have to log in again each time you visit a subpage. Similarly, your shopping cart in online stores is often managed in technically necessary cookies. Without these cookies, the website would not function correctly, as they enable basic functions and security measures.<\/span><\/p>\n

Technically non-essential cookies<\/b>, on the other hand, are not absolutely necessary for the website, but can improve your user experience and marketing measures. These cookies are used, for example, to track and analyze your user behavior. By analyzing how you as a user interact with the website, operators can gain valuable insights that help to optimize the website and increase the efficiency of marketing campaigns. Another example is cookies that are used to personalize content and advertising so that content tailored to you or targeted advertising can be displayed.<\/span><\/p>\n

Another important distinction is between so-called <\/span>first-party cookies<\/b> and<\/span> third-party cookies<\/b>. First-party cookies can only be read and written on the website you are visiting. Such cookies are usually set and read by the tools or plugins used on the website. Third-party cookies, on the other hand, come from external tools and their domains that are integrated on the website you are visiting, for example through advertisements or social media plugins. These cookies enable third-party providers to collect user data from you and to read and process it on other websites that use a tool from the same provider. Third-party cookies are criticized because they can be used to create extensive user profiles. Mozilla Firefox (since June 2019) Apple Safari (since April 2020) therefore blocks all third-party cookies by default.<\/span><\/p>\n

On the one hand, cookies enable an improved user experience, as you can be recognized as a returning user and your preferences can be stored. In addition, website performance and marketing measures can be made more efficient through cookies and the data collected as a result. On the other hand, there are also disadvantages for you as a website visitor, as the storage and processing of data is not always implemented in compliance with data protection regulations, and there is a risk of misuse, especially when using third-party cookies. In addition, blocking cookies can impair the functionality of the website, which can lead to errors on the website.<\/span><\/p>\n<\/div><\/div>

What types of cookies and similar technologies are there?<\/h2>\n

Information can technically be stored in various ways, which are usually summarized under the term cookies. The best known examples of this are HTTP cookies, local storage, session storage or IndexedDB. Each type of storage has different properties, which determine the technical handling, accessibility and authorized access to the information.<\/span><\/p>\n
