If you have registered a user account with us, we will additionally use a so-called "User ID" for this service. This is a unique, permanent, and personalized symbol sequence which we assign to you when you first log in to your user account. When you visit the website and are logged in to your user account, the website activities are assigned to your permanent user ID. This ID is not assigned to a specific end device (smartphone, laptop, etc.), but to you personally. In conjunction with Google Universal Analytics, this User ID is transmitted to Google, where it is used by us at Google as a pseudonym for you as a user. The data accumulated by Google are, therefore anonymized for Google, as the service does not have the option to create a link to your user account and therefore, to your personal data.
