What personal data we collect and why we collect it


When visitors post comments on the site, we collect the data displayed in the comment form, as well as the visitor’s IP address and user agent string (this identifies the browser) to help detect spam.

An anonymized string can be created from your email address (also called a hash) and passed to the Gravatar service to check if you are using it. The privacy policy of the Gravatar service can be found here: https://automattic.com/privacy/. After your comment is approved, your profile picture will be publicly visible in the context of your comment.

Images and videos at events

During our events, photographers and camera teams may also capture images of participants and customers attending the event. These images, films, and videos may be used for promotional purposes in our folders, brochures, flyers, on the event’s website, and/or its social media page, allowing you to view recordings of your participation in the event.

What analysis tools we use

Google Analytics

This website uses the “Google Tag Manager / Google Analytics” service, which is provided by Google Inc. (1600 Amphitheatre Parkway Mountain View, CA 94043, USA), to analyze website usage by users. The service uses “cookies” – text files that are stored on your terminal device. The information collected by the cookies is usually sent to a Google server in the USA and stored there. IP anonymization is used on this website. The IP address of the user is shortened within the member states of the EU and the European Economic Area. This shortening eliminates the personal reference of your IP address. As part of the agreement on order data, which the website operators have concluded with Google Inc., the latter uses the collected information to evaluate website use and website activity and provides services associated with internet use. You have the option of preventing the cookie from being stored on your device by making the appropriate settings in your browser. It is not guaranteed that you can access all features of this website without restrictions if your browser does not allow cookies. Furthermore, you can use a browser plug-in to prevent the information collected by cookies (including your IP address) from being sent to and used by Google Inc. The following link will take you to the corresponding plugin: https://tools.google.com/dlpage/gaoptout?hl=de Here you can find more information on data usage by Google Inc.: https://support.google.com/analytics/answer/6004245?hl=de


Leadfeeder is an analytics service for websites. It provides information about companies accessing websites and offers sales leads. See also Leadfeeder Privacy Notice.


Our website uses the Hotjar web analytics service provided by Hotjar Ltd. Hotjar Ltd is a European company based in Malta (Hotjar Ltd, Level 2, St Julians Business Centre, 3, Elia Zammit Street, St Julians STJ 1000, Malta, Europe, Tel: +1 (855) 464-6788).

This tool allows tracking movements on the websites where Hotjar is used (so-called heatmaps). For example, it is possible to see how far users scroll and which buttons users click on and how often. Furthermore, with the help of the tool it is also possible to collect feedback directly from the users of the website. Most importantly, Hotjar’s services can improve the functionality of the Hotjar-based website by making it more user-friendly, valuable and easier to use for the end users.

We pay special attention to the protection of your personal data when using this tool. So we can only track which buttons are clicked, mouse history, how far scrolled, device screen size, device type and browser information, geographic location (country only) and preferred language to display our website. Areas of the websites in which personal data of you or third parties are displayed are automatically hidden by Hotjar and are therefore not traceable at any time. In order to exclude a direct personal reference, IP addresses are only stored and processed anonymously. However, Hotjar uses various third-party services such as Google Analytics and Optimizely. It may therefore be the case that these services collect data transmitted by your browser as part of web page requests. These would be, for example, cookies or your IP address. In these exceptional cases, this processing is carried out in accordance with Art. 6 para. 1 lit. a DSGVO on the basis of the consent given by you for the purpose of statistical analysis of user behavior for optimization and marketing purposes.

Hotjar offers each user the option of using a “Do Not Track header” to prevent the use of the Hotjar tool so that no data is recorded about the visit to the respective website. This is a setting that all common browsers support in current versions. For this purpose, your browser sends a request to Hotjar with the instruction to deactivate the tracking of the respective user. If you use our websites with different browsers/computers, you have to set up the “Do Not Track header” for each of these browsers/computers separately.

When visiting a Hotjar-based website, you can prevent Hotjar from collecting your information at any time by going to our opt-out page at https://www.hotjar.com/legal/compliance/opt-out/ and clicking Disable Hotjar.
