Cookie Policy

Cookies are meant to make the user's visit to the website easier and more user-friendly. For example, with online shopping they enable the website to "remember" on your next visit what products you have in your shopping cart, or to automatically display your preferred layout and font size. However, not all cookies are useful and solely for the user's benefit.

For example, tracking cookies are used to follow your behaviour on websites and place advertising accordingly, or to make websites more user-friendly. You should accordingly think about which cookies to accept and which to reject. For this decision, it is helpful to know what kinds of cookies there are.

WHY ARE COOKIES NEEDED AT ALL? Session cookies (cookies which are technically necessary) are cookies which are essential for ensuring key functions of the website. Without these the website cannot be used as intended. Among other things, they ensure functionality when changing pages or switching between http and https to meet enhanced security requirements. These cookies collect anonymised information (no connection can be established with you personally) and cannot track your moves to other websites. They are only stored for the time of the session, which makes them session cookies. Your agreement to use these cookies is not required. We use cookies to make our service more user-friendly, effective and secure. Cookies also enable our systems to recognise your browser and offer you services even if you change pages. Some functions of our website cannot be offered without the use of cookies. These require your browser to be recognised even after changing pages. We need cookies and store the associated data for the following applications: shopping cart, language settings, login information. User data collected by technically required cookies are not used to create user profiles.

In other words, which page a user accesses most frequently, and whether error messages are displayed. These cookies do not store any further information, and they are used exclusively to enhance user-friendliness and match websites more specifically to the user. These data are also stored exclusively in anonymised form. The following tools are used for this purpose on this website:

Website analysis - Google Analytics
