Embedded Plugins

In addition to cookies, our websites use links to the following social networks:

Facebook (owned by Meta Platforms Inc, Hacker Way Menlo Park, CA 94025, USA)
Instagram (owned by Meta Platforms Inc, Hacker Way Menlo Park, CA 94025, USA)
LinkedIN (owned by LinkedIN, Corp, 605 W Maude Ave, Sunnyvale, CA 94085, USA)
YouTube (owned by YouTube, LLC, 901 Cherry Ave., San Bruno CA 94066, USA)

The respective buttons display the logos of individual social networks. However, these buttons are not standard plugins provided by social networks but are only functional links. They are activated only by intentional actions (clicking).

If you do not click on the buttons, no data will be transferred to social networks. By clicking on the buttons, you accept communication with the servers of the respective social network and will be linked to them.

Note that after clicking, the button functions as a so-called sharing plugin. The social network thus receives information about the visited website, which it can share with friends and contacts. If you are not logged in, you will be redirected to the login page of the clicked social network, leaving our site. If you are already logged in on that social network, the "like" or sharing function of the respective article will be active.

Part of the information obtained may include, for example, the time of the click, your IP address, details of the browser used, or language settings. This information depends on the functionality of the respective social network and its data handling rules.

When you click on such a button, we have no control over the data collected and processing activities. We are not responsible for this data processing, as we are not the "operator" according to the definitions of data protection legislation. In this regard, we are not aware of the extent of data collection, its legal basis, purpose, and retention period, and therefore, we cannot fully describe all the necessary details – these are the responsibility of the provider of the respective social network.

Also, note that data is transmitted regardless of whether you have an account with the social network provider or whether you are logged in. If you are logged in, your data will be directly associated with your account. Social network providers may also use various cookie files.

If you do not want social networks to collect data about you, do not click on the above mentioned buttons.

Information about the purposes and scope of data collection, further processing and use of data by the respective social network, and about rights and data protection settings can be found in the information provided by these social media sites (links were functional as of the date of preparing this policy, but we do not verify them further):
