Privacy Policy

Responsible party

We operate social media accounts on Twitter, Facebook, Google+ and YouTube. Our contact details are:

Grabbeallee 31
13156 Berlin

Telephone: +49-30-23256-1900

Beside us, there is also the operator of the social media platform itself in each case. In that sense, each of them is also responsible for carry out data processing, over which we unfortunately have only limited influence. In places where we are able to have an influence and set parameters for data processing, we work within the boundaries of the options available to us for ensuring the operators of social media platforms comply with data protection laws. In many instances, however, we are not able to influence the way data is processed by the operators of social media platforms nor do we know precisely what kind of data processing they undertake.

Data processing by us

The data you enter on our social media sites, such as comments, videos, photos, likes, tweets etc., will be published via the social media platform and not used or processed by us at any time for any other purposes. However, we reserve the right to erase content where necessary. Where appropriate, we will share your content on our site, if this is a function of the social media platform, and also communicate via the social media platform with you. The legal basis for this is Art. 6 (1) (1) f GDPR. This data processing occurs in the interest of our public relations and communication work.

If you wish to object to processing of certain data, please approach us via the contact details listed in our imprint. We will then give due consideration to your objection.

If you send a query to us via a social media platform, depending on the required response, we may refer you to other, secure communication channels that guarantee confidentiality. You always have the option of sending confidential queries to the address shown in our imprint.

As already mentioned, where the provider of social media platforms allow, we take care to ensure our social media sites comply with data protection law as much as possible. In particular, we therefore choose not to use the demographic, interest, behavioural or location-based target group definitions for advertising which may be made available to us by the operators of social media platforms. As far as the statistics made available to us by providers of social media platforms are concerned, we only have limited influence on them and cannot switch them off. However, we take care to ensure that no additional, optional statistics are provided to us by these providers.

Data processing by the operator of the social media platform

The operators of social media platforms use web tracking methods. Such web tracking may also occur irrespective of whether you are logged on or registered with the social media platform. As already mentioned, we unfortunately have no control over the web tracking methods of social media platforms. We are, for instance, unable to switch this method off.

Please be aware that it is not out of the question for a social media platform to use your profile and user behaviour data in order to assess such things as your habits, personal relationships, preferences etc., We have no control whatsoever over the processing of your data by the operator of a social media platform.

For more information about data processing by social media platform operators, please refer to the Privacy Policy of the relevant operator:

Your rights as a user

The GDPR gives you certain rights as a website user over the processing of your personal data:

1. Right to information (Art. 15 GDPR)

You have the right to demand confirmation about whether any personal data concerning you is being processed; where that is the case, you have the right to information about that personal data and other information listed in detail under Art. 15 GDPR.

2. Right to rectification and erasure (Art. 16 and 17 GDPR)

You have the right to demand correction of any inaccurate personal data without delay and also the right to have incomplete personal data completed where necessary.

In addition, you have the right to have your personal data erased without delay for one of the reasons listed in detail in Art. 17 GDPR, e.g. if the data is no longer required for the original purpose.

3. Right to restriction of processing (Art. 18 GDPR)

You have the right to demand restriction of processing for one of the reasons listed in Art. 18 GDPR as a prerequisite for restriction, e.g. if you have lodged an objection to such processing for the time it takes to check the accuracy of the data.

4. Right to data portability (Art. 20 GDPR)

In certain cases, listed in detail in Art. 20 GDPR, you have the right to receive the relevant personal data in a structured, commonly used and machine-readable format and also have the right to transmit the data to a third party.
