Content from third parties is incorporated into some pages of this website/blog, such as videos from YouTube. This always requires the providers of such content (herein after referred to as “third-party providers”) to register the IP address of the user, as without the IP address they cannot send the content to the browser of the user in question. Thus, the IP address is required for this content to be displayed. We make every effort to use only content from suppliers who use the IP address solely for the purposes of delivering the content. Nonetheless, we have no means of preventing third party suppliers from storing the IP address, for example for statistical purposes. Where we are aware of this happening, we inform users accordingly.

If you are signed in to your own account with one of these third-party suppliers, it is possible that the supplier will assign information about your usage to your respective personal user accounts of these platforms. You can prevent this from happening by signing out of your user account before using the plugins. For details of the purpose and scope of the data acquisition and the further processing and use of data by YouTube and and for your rights in this regard and the settings you can make to protect your privacy, please refer to the data use policies of YouTube.
