  • Browser type/version,
  • Operating system,

3. Cookies

To enhance your visit to our websites and enable you to use specific functions, we use "cookies" on various pages. These are small text files that are stored on your terminal. Some of the cookies we use are deleted after the end of the browser session, i.e. after you close your browser ("session cookies"). Other cookies remain on your terminal and enable us to recognise your browser next time you visit (persistent cookies). You can adjust your browser to ensure that you are informed about the setting of cookies and decide whether to accept them on an individual basis or whether to decline cookies in specific cases or in all instances. If you do not accept cookies, this may impair the functioning of our websites in some circumstances.

4. Triggered personal data collection, processing and use

Use of our websites does not require the collection or transmission of personal data.

Your personal data is only processed or used if you choose to enter your personal data. This may be necessary in the following cases:


(1) Enquiries and fulfilment of contract

We collect and process your personal data to the necessary extent in each case if you share it with us in the context of general or contract-related enquiries or other individual transactions.

We only use the data you provide to deal with your enquiry, to fulfil our contractual obligations to you and to execute the contracts concluded between you and us.  This may involve the need to pass on your personal data to companies that we use to provide the service or to execute the contract. These may include transport companies or other service providers, for instance.


(2) Registration for events

For inclusion in our events database, we store the data you entered each time you registered. We use this for the purpose of organising and holding the respective event, and invoicing if applicable. Any further use, e.g. for invitations to similar related events, is only made within the legally permitted framework.


(3) Transmission to governmental institutions and authorities

We only pass on data to duly authorised governmental institutions and authorities in the context of our statutory obligations or on the basis of a judicial decision if the data is not publicly accessible for the intended use.


(4) Advertising, market research, tailoring of telemedia

In line with and within the framework of the statutory regulations, we reserve the right to create usage profiles using pseudonyms for the purpose of advertising, market research or tailoring of telemedia. Usage profiles are not combined with data on the bearer of the pseudonym. You have the right to object to use of the data for advertising, market research or tailoring of telemedia.

This website uses Piwik for web analysis. To this end, usage information (including your shortened IP address) generated by "cookies" - text files - is transmitted to the server and stored for usage analysis purposes after being anonymised. The information generated by the cookie regarding your use of the site is not passed on to third parties.



If you do not agree with the storage and evaluation of the generated usage information by means of Piwik, you can object to this as follows. In this case, a deactivation cookie will be stored in your browser, meaning that Piwik will not collect any session data.

Note: If you delete your cookies, this means that the deactivation cookie will also be deleted and you will have to store it on your terminal again.


(5) Newsletter

If you register for one of the newsletters we issue, we use the data you provide on registration to verify the stated e-mail address and to provide and deliver the ordered newsletter.


5. Right to information

You can request information on your personal data stored by us, including in relation to the origin of this data, recipients or categories of recipients to whom the data is passed on, and the purpose of storage.

6. Deletion and blockage

We undertake to delete the personal data processed for our own purposes as soon as we no longer need it for the purpose for which it is stored. Blockage replaces deletion if deletion is not possible for legal reasons, contractual reasons or reasons related to the articles of association, if there is cause to assume that deletion would impair the legitimate interests of the party concerned or if the specific type of storage means that deletion is impossible or only possible with a disproportionately high degree of effort.

In addition, you can request the blockage, correction or deletion of your data collected by us at any time. Deletion is also performed if you withdraw your consent to the collection, processing and use of the personal data. If you withdraw your consent in the course of an ongoing transaction, deletion occurs immediately after the completion of this transaction.

Further legal deletion or blockage obligations remain unaffected.


If you have any questions about data protection, please direct them to the contact address stated on the "Disclaimer" page of our websites ("Imprint").

7. Technical and organisational measures

We undertake to carry out the technical and organisational measures required to ensure compliance with the data protection requirements, provided that the effort involved is commensurate with the intended protective purpose. In the case of communication by e-mail, we cannot guarantee full data security, and we therefore advise you to send confidential information by post.
