Our website uses social plugins (‘plugins’) from the social network, which is operated by Facebook Inc. (“Facebook”), 1601 S. California Ave, Palo Alto, CA 94304, USA. The plugins are marked by one of the Facebook logos or with the addition ‘Facebook Social Plugin’.

When you open a page on our website, which includes such a plugin, your browser will establish a direct connection to the Facebook server. The content of the plugins will be transferred directly to your browser and integrated within the website.

Thus we have no influence on the data gathered by the plugin and inform you according to our state of knowledge:

The embedded plugins provide Facebook with the information that you have accessed the corresponding page of our website. If you are logged into Facebook, your visit can be assigned to your Facebook account. If you interact with the plugins, for example by clicking “Like”, or entering a comment, the corresponding information is transmitted from your browser directly to Facebook and stored by it.

If you are not a member of Facebook, there is the possibility that Facebook learns your IP address and stores it.

The purpose and scope of data collection and further processing and use of data by Facebook as well as the relevant rights and settings options for protecting the privacy of users can be learned from the data privacy information of Facebook:

If you are a member of Facebook and do not want Facebook to collect data about yourself via our website and link it to the member data stored by Facebook, you must log out of Facebook before visiting the website.

It is also possible to block Facebook Social Plugins by using add-ons for your browser, for example the ‘Facebook Blocker’.

If you visit certain pages of the customer’s website during that period, Google and the customer will be able to tell that you saw the ad delivered by Google.
