Web Design & Texts: System Analysis and Modeling Group

Legal information:
Hasso Plattner Institute (HPI) constantly checks and updates the information on its web pages. Despite the utmost care taken, we cannot rule out that some of the data may since have become outdated. Therefore, we cannot accept liability for the currency, accuracy and completeness of the information displayed. The same applies to all other web pages that can be reached via hyperlink. HPI is not responsible for the content of websites which can be reached via such links. Furthermore, HPI reserves the right to make changes or additions to the information displayed. Content and structure of the HPI website is protected by copyright. The reproduction of information or data, in particular the use of texts, text excerpts or illustrative material, requires our prior approval.

Data Privacy

This privacy policy is an addition to the HPI privacy policy. This extension is necessary, because we are using additional services and technologies, which are not covered by the HPI privacy policy. It is also meant to provide a more specific imprint.

Additional covered sites are those below '', which are not published via the main HPI homepage, but instead proxied to internal, chair-controlled servers (keeping the same URL). It also includes some domains, which are directly proxied to our servers. Have in mind, that the servers, which are proxying our contents, store log information too. On the former, you can find more information in the HPI privacy policy.

Group Websites

Each time you access websites of the System Analysis and Modeling Chair, details of your request will be stored in log files on our servers to keep our internet service running serving your needs. We save data about:

  • Name of the requested file (URL)
  • Date and time
  • Transferred data volume
  • Notification, whether the retrieval was successful
  • Information about the Operating System and Browser (so called UserAgent, automatically sent by the browser)

The log data will be kept for 14 days, before the log files automatically get deleted.

The data will not be transfered, nor will there be any automated analysis. It is meant for manual security and debug analysis only.

External Resources

When loading external resources (e.g. images hosted on external servers), we might automatically receive the IP address of the device (or your proxy server) you are using to access the Internet, which could be used to infer your geographical location. However, this information is not stored in our servers.

Embedded content from other websites

Articles on this site may include embedded content (e.g. videos, images, articles, etc.). Embedded content from other websites behaves in the exact same way as if the visitor has visited the other website.

Additional Services/Technologies

Finally, some of the group websites might be published using additional services/technologies (e.g. from the Company Automattic). In these cases, we have taken measures to ensure that no personal information is stored, user input that can be used to identify the user is disabled,  and, where applicable, software versions that are compliant with GDPR are installed.
