3. Processing your data

The processing of your personal data generally takes place in a member state of the European Union or in another state party to the Agreement on the European Economic Area. A transfer of personal data to a third country or access to this data from a third country will only take place if the special requirements of Art. 44 et seq. DSGVO are fulfilled (e.g. by agreeing on standard contractual clauses or if the recipient acts on the basis of a legal basis decided by the European Commission pursuant to Art. 45 (1) DSGVO (so-called adequacy decision)).

However, special features apply to the use of social media channels. We would like to point out that we are not able to track all processing operations on the social media channels. Depending on the provider, processing operations may be carried out by the operators of the social media channels over which we have no influence and of which we gain no knowledge, in particular no data from you. For details, please refer to the terms of use and data protection provisions of the respective social media channels. You can find these under Legal basis and revocation option at the end of this chapter.

To the extent that we have control over the processing of your data, we will ensure that the applicable data protection regulations are complied with as described.

joint responsibility according to Art. 26 GDPR:
According to the European Court of Justice (ECJ), we are jointly responsible for the processing of your personal data with the provider of the respective social media channel. Insofar as the social media channels process personal data based on our instructions, the social media channels process your personal data under our responsibility as our processors. You can find the addresses of our processors under "Recipients of the data".

Please note that your data may be processed outside the European Union. Unfortunately, this is not currently possible in accordance with data protection regulations.

Note: Data transfer to the USA
We would like to point out that in its ruling of 16.07.2020 (Case C-311/18), the ECJ declared the EU-US Privacy Shield agreement on the permissible transfer of data between the EU and the USA to be inadmissible and that personal data cannot currently be transferred to the USA in accordance with data protection law. The reason for this is existing laws in the USA that give security authorities far-reaching powers to monitor "foreign communications". We hereby expressly draw your attention to this risk.
