This Website uses Google Analytics, a web analysis service provided by Google Inc. Google Analytics places a cookie on your computer to recognize you on an anonymous basis when you return to a particular website. Google uses the information obtained by the cookie to store a profile of which pages you have visited within a session.
The information generated by the cookie about the use of this website is usually transferred to a Google Inc. server in the USA and stored there. However, due to the activation of IP anonymization on this website, your IP address will previously be cut back by Google Inc. within member states of the European Union or in other states party to the Agreement on the European Economic Area. Only in exceptional cases will the full IP address be transmitted to a Google server in the USA and shortened there. Google acts as Hitachi’s contract processor and analyzes the data received only on Hitachi’s behalf. Hitachi uses the information we receive from Google Analytics for business planning, business operations and marketing purposes to better understand how we can improve the content and experience of our web services.

Google Tag Manager
Google Tag Manager is a solution for managing website tags from a single interface. The tool itself (which implements the tags) is a cookie-less domain and does not collect any personal data. The tool triggers other tags, which in turn may collect data. Google Tag Manager does not access this personal information. If deactivation has been made at the domain or cookie level, it will remain in effect for all tracking tags implemented with Google Tag Manager.

We use YouTube for the integration of videos. YouTube is operated by YouTube LLC, headquartered at 901 Cherry Avenue, San Bruno, CA 94066, USA. YouTube is represented by Google Inc. based at 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA.
On some of our Websites we use plugins from YouTube. When you access the websites on our Website that are provided with such a plugin a connection to the YouTube servers is established and the plugin is displayed. This transmits to the YouTube server which of our Websites you have visited. If you are logged in as a YouTube member, YouTube assigns this information to your personal user account. When using the plugin, e.g. clicking the start button of a video, this information is also assigned to your user account. You can prevent this assignment by logging out of your YouTube account and other user accounts of YouTube LLC and Google Inc. and deleting the corresponding cookies of the companies before using our Website.
