5. Information on cookies and targeting

We use so-called browser cookies to collect information about your use of our website. Cookies are small text files that are stored on your hard drive where specific preferences and data regarding the exchange of information between our system and your browser is stored. A cookie generally contains the name of the domain from which the cookie data was sent and information about the age of the cookie and an alphanumeric identification sign. Cookies enable our systems to recognize the user’s device and to make possibly existing settings available immediately. As soon as a user accesses the platform, a cookie is transferred to the hard drive of the respective user’s computer. Cookies help us to improve our website and enable us to offer you a better service that is even-more customized to your needs. They enable us to recognize your computer when you return to our website and so:

  • To store information about your preferred activities on our website and so to orient our website on your individual interests. This includes, for example, advertising that corresponds to your personal interests;
  • To increase the speed with which your queries are processed; The use of cookies is justified on the basis of our legitimate interest in a needs-based design and the statistical evaluation of our website and the fact that your legitimate interests are not overriding pursuant to Article 6 (1) (f) GDPR.

The cookies used by us only store the aforementioned data about your use of our website. This is carried out not on the basis of an assignment to you personally, but by the allocation of an identification number to the cookie (“cookie ID”). The cookie ID is not associated with your name, IP address or similar data that would enable the attribution of the cookie to you. You can find out how to prevent the use of browser cookies under Item 5.5.

In addition, we use so-called server-side tracking. This has the advantage for you that once you have given your consent to the setting of cookies, your data (such as your IP address) will be shortened/anonymized by us before being passed on to third parties. For this purpose, a separate server is used by us as an intermediary in the process. In any case, your data will not be collected and processed without your consent, where necessary.

Our website uses so-called tracking technologies (you will find further details in Item 6). We use these technologies in order to make the Internet offer more interesting for you. This technology enables Internet users who have already shown an interest in our website to be presented with advertising on the websites of our partners. The display of these advertisements on our partners’ websites takes place based on the use of cookie technology and an analysis of the previous user behaviour. This analysis is carried out using a pseudonym and user profiles with your personal data are not put together.

Should you wish to opt out of this tracking process, you can refuse to allow the setting of a cookie required by this process:

  • For example, by means of a browser setting that deactivates the automatic setting of cookies in general. Please use e.g. the “Do not track” (“DNT”) option of your web browser

Alternatively, you can use the following link: Disable Google Analytics' collection of data for this website

Please note that you must carry out this step individually for every one of your terminals and/or browsers.

We work together with business partners who support us in designing our Internet presence and the website to make it more interesting for you. For this reason, cookies from these partner companies are also stored on your hard drive when you visit the website. These cookies automatically delete themselves after a preset time. The cookies from our partner companies are also only used with a cookie ID to collect data that enables our advertising partners to address you with advertising that could genuinely be of interest to you. You can find out how to prevent the use of cookies under Item 5.5.

Should you not wish the use of browser cookies, you can set your browser in such a way that the storage of cookies is not accepted. Please note that in this case you may only be able to use our website on a limited basis or not at all. Should you wish to only accept our own cookies, and not the cookies of our service providers and partners, you can select the setting “Block third-party cookies” in your browser.

6. Pseudonymous user profiles and cookies

For more Information about cookies and pseudonymous user profiles please have a look at our cookie-notice.

7. Data processing by social networks

We maintain publicly accessible profiles in social networks. The individual social networks that we use are listed below.

Social networks such as Facebook, Google+ etc. can normally carry out comprehensive analyses of your behaviour as a user when you visit their websites or a website with integrated social media content (e.g. Like buttons or advertising banners). Numerous processing operations that are relevant to data protection are triggered by a visit to one of our social media sites.

Specifically, if you visit one of our social media sites while you are logged in to your social media account, the operator of the social media portal can assign this visit to your user account. Under certain circumstances, your personal data may also be recorded when you are not logged in or if you do not have an account with the respective social media portal. In this case, the data acquisition is accomplished e.g. by using cookies that are saved on your terminal or by recording your IP address.

The operators of the social media portals can use the data collected in this way to create user profiles in which your preferences and interests are stored. As a result, you can be presented with interest-based advertising both inside and outside the respective social media site. If you have an account with the respective social network, the interest-based advertising can be displayed on all devices on which you are, or have been, logged in.

Please also note that we are unable to trace all of the processing operations on the social media portals. Depending on the provider, further processing operations could be carried out by the operators of the social media portals. You can find details of such further processing in the terms and conditions of use and the privacy policies of the respective social media portals.

Legal basis

Our social media sites are intended to ensure the most comprehensive possible presence in the Internet. This is in our legitimate interest pursuant to Article 6 (1) (f) GDPR. The analytical processes initiated by the social networks may be based on differing legal foundations, which must be stated by the operators of the social networks (e.g. consent pursuant to Article 6 (1) (a) GDPR).

Controller and assertion of rights

When you visit one of our social media sites (e.g. Facebook), we are jointly responsible with the operator of the social media platform for the data processing operations triggered by this visit. You can basically assert your rights (access, rectification, deletion, restriction of processing, data portability and complaint) both against us and against the operator of the respective social media portal (e.g. against Facebook).

Please note that despite our joint responsibility with the operators of the social media portals we do not have comprehensive influence on the data processing operations of the social media portals. Our opportunities essentially depend on the corporate policies of the respective provider.

Duration of storage

The data we collect directly through our social media sites is deleted by our systems as soon as there is no longer any need for storing this data, if you ask us to delete it, or if you revoke your consent to have the data stored. Stored cookies remain on your device until you delete them. This clause does not affect mandatory legal requirements, in particular those specifying storage periods.

We have no influence on the length of time that your data is stored by the operators of the social networks for their own purposes. To find out more, please refer to the information provided by the operators of the respective social networks (e.g. read their privacy policies; see below).

8. Shariff

We do not use the plugins of the social networks Facebook, Twitter, Google+, LinkedIn and Xing themselves on our website. Our buttons for sharing content via social media are implemented using the software “Shariff,” which first transmits the data to the respective network operator when you click the buttons. If you would like to learn more about Shariff, click here.

Various data are first transferred to the respective social network when you click on the corresponding button. These data can include:

  • Date and time of the website access
  • URL of the website which the visitor is browsing
  • URL of the website which the visitor previously visited
  • Browser used
  • Operating system used

IP address of the visitor Insofar as you are logged in to the respective social network (Facebook, Twitter, Google+, LinkedIn or Xing) in parallel with your visit to our site, it is not excluded that the provider can associate the visit with your social network account. When you use the plugin functions (e. g. clicking on the “Like” button, posting a comment), this information is also transferred directly by your browser to the respective social network and possibly stored there. Please consult the privacy policies of Facebook, Twitter, Google+, LinkedIn and Xing to find out more about the purpose and scope of the networks’ data collection activities as well as their further processing and use of the data.

7. Transfer of data

In principle, a transfer of your personal information without your prior express consent will only take place in the following cases:

  • When it is required for the investigation of an unlawful use of our services or for the prosecution, personal data are transferred to the law-enforcement authorities and if necessary to injured third parties. However, this only occurs when there are concrete indications of unlawful or abusive behaviour. A transfer can also take place when it is necessary for the enforcement of terms and conditions of use or of other agreements. We are also legally obliged to provide information to specific public authorities on request. These are prosecutorial authorities, authorities that prosecute misdemeanours punishable by fines and the financial authorities. The transfer of this data takes place on the basis of our legitimate interest in combatting misuse, the prosecution of criminal offences, the safeguarding, assertion and enforcement of claims and the fact that your rights and interests with regard to the protection of personal data are not overriding pursuant to Article 6 (1) (f) GDPR.
  • We rely on contractually bound external companies and external service providers (“processors”) for the provision of the services. In such cases personal data are transferred to these processors in order to enable them to carry out the further processing. These processors are carefully selected by us and regularly checked in order to ensure that your right to privacy remains protected. The processors may only use the data for the specific purposes of the processing as specified by us and are in addition contractually obligated by us to handle your data exclusively in accordance with this privacy policy and the German data protection legislation.
  • In the context of the further development of our business it is possible that the structure of Koelnmesse GmbH changes in that the legal form is changed or subsidiaries, business units or constituent parts are established, purchased or sold. In the event of such transactions the customer information will be transferred along with the part of the company being transferred. We will ensure that every such transfer of personal data to third parties to the extent described above takes place in conformity with this privacy policy and with the relevant data protection legislation.

A possible transfer of the personal data is justified by our legitimate interests in adapting our business form to economic and legal factors as required and the fact that your rights and interests with regard to the protection of personal data are not overriding pursuant to Article 6 (1) (f) GDPR.

10. Transfer of data to third countries

The data can in some cases be transferred in the scope described above to countries outside the European Economic Area (EEA). These countries do not have a standard of data protection comparable with the standard of protection within the EU (e. g. USA, China or India). For the protection of your data, those of our group companies and contract partners located outside the EEA to whom data should be transferred, such as foreign representatives, are obligated on the basis of the EU standard contractual clauses for the transfer of personal data to third countries to guarantee adequate data protection.
