When users post comments on Messe Berlin websites or online offers/presence, these can be accessed by all website visitors worldwide (legal basis: Art. 6 (1) (a) GDPR).

On some websites and online offers/presence of Messe Berlin, services and functions of third parties may be integrated in the form of external links. These links are marked. When users click on these links and use these offers (legal basis: Art. 6 (1) (a) GDPR), they leave the Messe Berlin website or online offer/presence and are redirected to the website of the respective third party, which may use its own cookies and tracking technologies. These third parties process the data as own controllers within the meaning of the GDPR. For more information, please refer to the data protection and cookie notices of the respective third party.

In order to carry out certain processing activities in connection with the purposes mentioned in section 3 (in particular some special services, shipping/mailings, market research/customer surveys, hosting and IT support, website and content management, data management), external service providers are used which process the personal data on behalf of Messe Berlin (so-called "processors“) or in case of telecommunications providers or postal/courier service providers as own controllers (legal basis: Art. 6 (1) (f) GDPR).

Personal data may be disclosed to authorities and public bodies if Messe Berlin is legally obliged to do so, whether on the basis of laws and regulations (e.g., as part of supervisory authority procedures or by court order, resolution, judgment and the like) (legal basis: Art. 6 (1) (c) or (e) GDPR). For compliance with tax and commercial laws and regulations, personal data are disclosed to the tax and other competent authorities and public institutions.

The categories of recipients of the personal data also include courts and lawyers in the context of litigation, legal disputes and for the purpose of legal advice as well as auditors (legal basis: Art. 6 (1) (c) and (f) GDPR.

Some of the foreign representative offices, companies of the Messe Berlin group of companies, processors, service providers and third-party providers of social media and social media channels, cookies and tracking technologies are located in third countries outside the EU, which do not provide the same level of data protection as the EU, in particular due to the absence of a legal framework, independent supervisory authorities or data protection rights and remedies. The transfer of personal data to those third countries takes place, if the European Commission has adopted a so-called adequacy decision in this respect (Art. 45 (3) GDPR) (see here) or otherwise where appropriate safeguards in accordance with Art. 46 GDPR have been provided, in particular standard data protection clauses adopted by the European Commission pursuant to Art. 46 (2) (c) GDPR (for the latest version see here) and, where necessary, supplementary measures. A copy of the safeguards can be obtained upon request (e.g., by e-mail – for contact details see section 1 above).

With regard to the transfer of data to companies of the Messe Berlin group of companies and other website visitors or users, the transfer of data to third countries is necessary for the performance of the contract (Art. 49 (1) (b/c) GDPR); otherwise, it takes place on the basis of explicit consent of the users despite the lack of adequate data protection in the third countries outside the EU and the associated risks (Art. 49 (1) (a) GDPR).

Stored personal data will be erased once they are no longer needed for achieving the relevant purpose of their processing. If users unsubscribe from the newsletter, the data stored for this purpose will be deleted. The comments and the associated data (e.g., IP address) remain on the websites and online offers/presence of Messe Berlin until the commented content has been completely deleted or the comments have to be deleted for legal reasons (e.g., offensive comments).

Insofar as processing is based on consent or on the basis of the legitimate interest of Messe Berlin or a company of the Messe Berlin group of companies, the data in question will no longer be processed for the associated purpose after receipt of the withdrawal of consent or receipt of the objection to the processing and, if applicable, will be deleted, unless legal exceptions to this rule are met. Notwithstanding the foregoing, data with regard to which there are obligations to retain data under commercial or tax law (e.g., German Trade Act) will only be deleted after expiry of the statutory periods (generally 6 or 10 years). Evidence of consent given will be stored for a maximum of three years after the date on which the consent is revoked or otherwise becomes invalid.

To exercise the following rights, users and other data subjects can contact the controller at any time (contact details see section 1 above).

Rights of the data subjects pursuant to Art. 12-21 GDPR: the right to access about personal data, the right to rectification, erasure and data portability as well as to restriction of processing. If consent has been given, this can be withdrawn at any time with effect for the future.

Rights of objection

Insofar as the processing is based on the legal basis of legitimate interest (Art. 6 (1) (f) GDPR) (see section 3 above), the data subject has the right to object to the processing of personal data at any time on grounds relating to the particular situation of the data subject.

Furthermore, an objection to the processing and use of the data for advertising purposes can be lodged at any time with effect for the future. The newsletters also include an unsubscribe link.

If data subjects are of the opinion that the data processing violates data protection law, they have the right to lodge a complaint with the competent supervisory authority of their choice (Art. 77 GDPR in conjunction with section 19 of the German Federal Data Protection Act (Bundesdatenschutzgesetz)).
