Social Media Buttons

Functions (plugins) of third-party providers or social media platforms (Facebook, Twitter, Google+, etc.) are embedded into the websites of SIX. These plugins enable the User to share content on the social networks mentioned. The interfaces are deactivated by default when the website is accessed. This means that no personal data is transmitted to the respective third-party providers without intervention on the part of the User. Once the User has activated the interfaces, data (incl. also personal data) is automatically transmitted to the relevant third-party providers by the plug-ins. If the User is simultaneously logged in to the network of the respective third-party provider when they visit the website, the third-party provider can assign the visit to the User's network account. SIX has no influence on this. The purpose and scope of such a form of data collection and the further processing and usage of personal data are outlined in the data protection guidelines of the individual social networks. Users can also obtain information there on rights and settings options in relation to protecting their privacy.
