We use cookies in certain areas of our website, for example to recognize the preferences of visitors and to design our site optimally. This allows easier navigation. Cookies also help us to identify the most popular areas of our website.

Cookies are small files stored on the hard drive of a visitor’s device. They allow to keep information for a certain period of time and to identify the visitor’s computer.

For a better guidance of the user, we use permanent cookies. We also use session cookies, which are automatically deleted when you close your browser. You can configure your browser to inform you of the location of cookies.

We use the following categories of cookies on our website:

  • Cookies absolutely necessary to access the site
  • Performance Cookies
  • Targeting cookies
  • Web Beacons

Required cookies: These cookies are necessary for you to navigate the website and use its features, such as access to password protected areas. Without these cookies, we will not be able to provide you with certain services requested by you. We use essential cookies to uniquely identify registered users so that they are recognized during their stay and during the site visit.

Performance cookies: These cookies collect information about how visitors use a website, for example on the pages they visit most often and if they receive error messages from websites. These cookies do not collect data that can be used to identify visitors. All information collected through these cookies is anonymous and is only intended to improve the functionality and service of the site. We therefore use performance cookies to compile statistics on the use of our site and to see if our advertising campaigns are effective.

Targeting Cookies: These cookies are used to personalize online advertising (see section 8), specifically for you and your interests. They also help to limit the frequency of an ad, measure the effectiveness of an ad campaign, and understand how people behave after an ad is served. Targeting cookies are usually placed on the advertising network site with the permission of the site operator. They recognize that the user has visited a webpage and give this information to others, eg. advertising companies. They are often linked to a webpage feature provided by that company. We therefore use targeting cookies to connect to social networks, which can then use your visit information to personalize advertising on other websites, and to provide information about your visit.

Web-Beacons: Our website uses Google AdSense, an online advertising service provided by Google Inc. (“Google”). Google AdSense uses “cookies”, which are text files that are stored on the user’s computer and that allow an analysis of the use of the site. Google AdSense uses invisible pixels (invisible graphics). These web beacons can be used to evaluate information such as visitor traffic on the webpages. The information generated by cookies and web-beacons concerning the use of this website (including the IP address of users) and the dissemination of advertising formats are transmitted and stored by Google on servers located in the United States. This information may be disclosed by Google to Google contractors. However, Google will not merge your IP address with other data that you have stored. You can oppose web analytics via Google Analytics.


Our website collects and processes data about your user behaviour. This will give us an overview of the usability of our website. We also want to make our advertising as useful and interesting as possible. For this purpose, we make offers and recommendations of products corresponding to your personal interests (personalized offers). The personalized offers are based on the analysis of your activities on our website, your participation in our actions and your use of our electronic media. Specifically, we use the following information to personalize the products and advertisements tailored to your needs and interests:

  • The data you provide when registering for an event, processing requests, orders and reservations
  • The information generated automatically when visiting our website, including the date and time of the visit (usage data) and the information that results from it (for example, the content you frequently visit.
  • Acknowledgments of receipt and reading of emails.

Information is collected about your activities on this website (eg browsing behavior, sub-pages visited site). All usage data is stored using a pseudonym, so that personal identification is fundamentally excluded.

The personalized offers can be sent by postal mail or, if you have given your consent, by e-mail or by push message. You may revoke this consent at any time. A message written to is sufficient.


Google Analytics:

To personalize our website, we create pseudonymous user profiles using Google Analytics Web Analytics and Google Analytics Google Inc. (1600 Amphitheater Parkway Mountain View, CA 94043, USA) . Google Analytics uses cookies, which are text files stored on your computer that allow an analysis of your use of the website. The information generated by the cookie about your use of this site is generally transmitted to a Google server in the United States and stored there. However, as we have enabled IP anonymization on this site, your IP address will be truncated by Google in the Member States of the European Union or in other Contracting States to the Agreement on the European Economic Area. Only in exceptional cases will the full IP address be sent to a Google server in the United States and only then shortened. Google will use this information to evaluate your use of the site for us, to compile reports on website activity and to provide us with other services related to website activity and internet usage. The IP address provided by Google Analytics as part of Google Analytics will not be merged with other Google data.

This site uses Google Analytics with the extension “_anonymizeIp ()”. As a result, IP addresses are processed in abbreviated form, which means that a direct personal reference can be excluded. With Google Universal Analytics, we are able to map data across multiple device sessions and interactions to a pseudonymous user ID, analyzing a user’s activity across multiple devices. The use of Google Analytics complies with the conditions that the European Data Protection Authorities have accepted with Google. Information provided by European representatives of Google Inc.: Google Dublin, Google Ireland Ltd, Gordon House, Barrow Street, Dublin 4, Ireland, Fax: +353 (1) 436 1001. Terms of Use: http: // www., Privacy: and Privacy Policy: privacy? hl = en & gl = fr. You may at any time contradict the creation of pseudonymous user profiles. There are several ways to do this:

  • One way to oppose web analytics via Google Analytics is to set a disabling cookie that tells Google not to store or use your information for web analytics. You can prevent Google Analytics from using your data by using the Google Analytics JavaScript browser add-in (ga.js, analytics.js, dc.js). If you want to download the browser add-on, click here.
  • You can prevent the storage of cookies used for profiling by a corresponding setting of your browser software. However, we draw your attention to the fact that in this case, you may not be able to use all the features of this website as much as possible.

For online advertising based on the use of data, we use retargeting “markers” to place advertisements based on your interests on third-party sites. This retargeting marker is a JavaScript element that is placed in the source code of the site. When a user visits a page on a website containing a retargeting marker, an online advertising provider (for example, Google, Facebook) places a cookie on the user’s computer and traces that audience list. The respective retargeting providers use the cookie to enter data of interest (for example, who visited the pages of the XLETIX site or who searched the site) using pseudonyms. This information will then be used by retargeting providers to show interest-based advertising. No personal data will be stored and no user profile will be merged with personal data. However, the retargeting provider can potentially identify you and assign you user behavior, especially if you are a registered user of the retargeting provider (for example, having a Google or Facebook account).

For online advertising based on the use of data, we use the following tools:
