8. Data protection provisions about the application and use of TwitterOn this website, the controller has integrated components of Twitter. Twitter is a multilingual, publicly-accessible microblogging service on which users may publish and spread so-called ‘tweets,’ e.g. short messages, which are limited to 280 characters. These short messages are available for everyone, including those who are not logged on to Twitter. The tweets are also displayed to so-called followers of the respective user. Followers are other Twitter users who follow a user's tweets. Furthermore, Twitter allows you to address a wide audience via hashtags, links or retweets.The operating company of Twitter is Twitter, Inc., 1355 Market Street, Suite 900, San Francisco, CA 94103, UNITED STATES.With each call-up to one of the individual pages of this Internet site, which is operated by the controller and on which a Twitter component (Twitter button) was integrated, the Internet browser on the information technology system of the data subject is automatically prompted to download a display of the corresponding Twitter component of Twitter. Further information about the Twitter buttons is available under https://about.twitter.com/de/resources/buttons. During the course of this technical procedure, Twitter gains knowledge of what specific sub-page of our website was visited by the data subject. The purpose of the integration of the Twitter component is a retransmission of the contents of this website to allow our users to introduce this web page to the digital world and increase our visitor numbers.If the data subject is logged in at the same time on Twitter, Twitter detects with every call-up to our website by the data subject and for the entire duration of their stay on our Internet site which specific sub-page of our Internet page was visited by the data subject. This information is collected through the Twitter component and associated with the respective Twitter account of the data subject. If the data subject clicks on one of the Twitter buttons integrated on our website, then Twitter assigns this information to the personal Twitter user account of the data subject and stores the personal data.Twitter receives information via the Twitter component that the data subject has visited our website, provided that the data subject is logged in on Twitter at the time of the call-up to our website. This occurs regardless of whether the person clicks on the Twitter component or not. If such a transmission of information to Twitter is not desirable for the data subject, then he or she may prevent this by logging off from their Twitter account before a call-up to our website is made.The applicable data protection provisions of Twitter may be accessed under https://twitter.com/privacy?lang=en.9.
