We also use cookies to match our Internet product to your wishes as a customer and to make web surfing with us as comfortable as possible for you. We also use cookies to optimize our advertising. With cookies we can present you with advertising and/or particular products and services that might be of special interest to you based on your use of our website. Our aim is to make our web product as attractive as possible for you and to present you with advertising that corresponds to your areas of interest.

                  b. Which cookies do we use?
                  Most of the cookies we use are automatically deleted from your computer or mobile device after your browser session has ended (so-called session cookies). For example, we use session cookies to store your regional and language defaults and your shopping basket over different sites in a web session.

                  In addition, we use temporary and permanent cookies. These remain stored on your computer or mobile device after the end of the browser session. Then, when you revisit one of our websites your preferred entries and settings are automatically identified. Depending on which type they are, these temporary and permanent cookies remain stored on your computer or mobile device for between one month and ten years, and are automatically deactivated after the end of the programmed period. They are used to make our websites more user friendly, more effective and more secure. Thanks to these cookies you will have, for example, information displayed on the site that is tailored especially to your interests (e.g., display of local currency).

                  It is also possible that the cookies stored on your computer or mobile device may come from partner companies. These cookies enable our partner companies to target you with advertising that might actually be of interest to you or are used to e.g., determine your location for the purpose of currency conversion. Cookies of partner companies remain stored on your computer or mobile device for between one month and ten years, and are automatically deactivated after the end of the programmed period.

                  c. Which data are stored in cookies?
                  No personal data are stored in the cookies we use. The cookies used by us cannot be assigned to a specific person. When a cookie is activated the person will be allocated an identification number.

                  d. How can you can prevent the storage of cookies?
                  Most web browsers automatically accept cookies. They can, however, instruct your browser not to accept any cookies, or to ask you each time before a cookie from a website you have visited is accepted. You can also delete cookies from your computer or mobile device by using the appropriate function on your browser. If you decide not to accept our cookies or the cookies of our partner companies, you will not be able to see certain information on our websites or use a number of functions which should improve your visit.

                  How do we use log files?
                  Every time you access our websites, certain usage data are transmitted to us by your Internet browser for technical reasons, and stored in protocol files, known as log files. The usage data in question are the following: the date and time our website is called up; the name of the website called up; the IP address of your computer or mobile device; the address of the website from which you accessed our website; the volume of data transferred and the name and version of your browser.

                  Analysis of the log files helps us to further improve our Internet products and make them more user friendly, to find and remove errors more quickly, and to control server capacities. Using log files, we can, for instance, determine the time when the use of our Internet products is particularly popular and make appropriate data volumes available to guarantee you optimum usage.

                  How do we use web analysis tools?
                  In order to constantly improve and optimize our Internet offering, we use what are known as tracking technologies. Web analysis tools provide us with statistics and graphics which provide us with information about the use of our websites. This involves data about the use of a website being transferred to the server used. Depending on the provider of a web analysis tool, these servers may be located abroad. For the most frequently used web analysis tool, Google Analytics, these data are transferred including shortened IP addresses, which prevents the identification of individual devices. Google complies with the data protection rules of the "Swiss-U.S. Privacy ShieldFramework" and is registered with the “Swiss-U.S. Privacy Shield” program of the US Department of Commerce (Information about the “Swiss-U.S. Privacy Shield” can be found under The IP address transmitted by your browser within the framework of Google Analytics will not be merged with other Google data. Transfer of these data by Google to third parties can only take place on the basis of legal regulations or as part of the order data processing.

                  Should other web analysis tools be used, the data collection process is essentially the same.

                  You may prevent the recording of the data generated by cookies and relating to your use of the website (incl. your IP address) at Google, as well as the processing of these data by Google, by downloading and installing the browser plugin available under the following link ( You will find more detailed information about Google Analytics and data protection at or

                  How do we use social plugins?
                  Our websites use social plugins, e.g. from TikTok, Instagram or Facebook. The plugins are labelled with the logo of the provider.

                  When you call up our websites which contain such a plugin, your browser sets up a direct connection with the provider’s computers. The content of the plugin is transmitted by the provider site directly to your browser, which integrates it into the website. By integrating plugins the provider receives the information that you have called up our website. If you are simultaneously logged in to the provider, the provider can assign the visit to your profile. If you interact with the plugins the relevant information is transmitted by your browser directly to the provider and stored there.

                  If you do not want the provider to collect data about you via our website, you must log out of the provider before you visit our website. Even if you are logged out, providers collect anonymized data via social plugins set up a cookie for you. If you log into the provider at a later time, these data may be assigned to your profile.

                  If a login is provided via a social login service data are exchanged between the provider and our website. By using such login services you agree to the transfer of data.

                  If you do not want the provider to collect data about you via these cookies, you can select the “block cookies from third-party providers function in your browser settings. Then if there is embedded content from other providers, the browser does not send any cookies to the server. It is possible that with this setting other functions on our website will no longer function.
