Privacy Information for Visitors of our Twitter Account

Our Twitter appearance allows us to present our company to the users of this network and to communicate with them. The data provided directly by you and by Twitter will be used exclusively for the purpose of presenting our company to the users of the network and to communicate with them as well as increase our visibility and further our image building as a legitimate interest in the sense of Article 6 paragraph 1 point (f) GDPR, in order to be able to offer you information most interesting to you.

In case you visit our Twitter Account, Twitter collects your IP address and other personal information using cookies. Cookies are small text files that are stored by Twitter via the browser on a storage medium of the device used by the website visitor (PC, notebook, tablet, smartphone, etc.). This information is retrieved during subsequent visits to the website and enables the website to recognize the user device.

If you are logged in to your Twitter Account and visit our Twitter profile, this may be associated with your profile. We have no influence on the data collection and further processing by Twitter, to what extent this happens and how long this data is stored.

By creating a Twitter Account, we contribute to the processing of our visitors’ personal information, irrespective of whether they are registered or logged in to Twitter. Although Twitter provides us with certain data collected through cookies or concerning our videos in anonymous form, the compilation of these statistics is based on the previous processing of personal data.

If you are logged in with Twitter, you agree to Twitters terms of use, privacy and cookie policies and to Twitters processing of your personal data, of which we have no control over.
