Storing anonymous users' cookies

We use cookie statistics on this page to determine how many users have visited us, what kind of tools they have used (Mac and Windows - with this we can see where our site does not work as it does in a variety of environments), the pages you see, and the like. With these programs, we can still improve your user experience. Such an analysis also provides a better insight into how users come to our side and whether they are coming back. On this basis, we can invest in the improvement and development of the user experience for you rather than in marketing activities.

We also use technology that allows us to determine the users who called us (e.g., a browser or ad with the phone number you clicked). In this way, we can get information about how people come to us. Please note that if you call us at the telephone number displayed on our website, we will only know to a certain extent how you found us. All of this will allow us to reduce the costs for you.

Cookies for marketing activities. Cookies are widely used in digital marketing. Through it, neither we nor our external partners can receive personal information from you.

We do not recommend blocking the vast majority of cookies as ads provide free use of the sites. If you block cookies, it means not only that you will not see any ads, but also that the site can no longer be optimised for your wishes and interests, which reduces usability. Cookies have a technology that allows us to accurately and with your help the so-called "remarketing cookies" when you visit certain websites. These ads are designed so that you can buy a product at a reduced price. And do not worry, the process is void anonymous. You may block cookies at any time, as described below.
