This information concerning data protection / this data protection declaration relates to the web servers of the High-Performance Computing Center Stuttgart (in particular www.hlrs.de).
Should you access this or other websites, you transfer data to our web server via your browser. The following data is temporarily recorded in a log file whilst a connection is established:
The processing of the data in this log file takes place as follows:
In addition, when accessing websites, the date and time stamp, IP address + port (source), IP address + port (target) and the package size are recorded in the active network components of the University of Stuttgart.
The temporary storage of the IP address by the system is necessary in order to deliver the website to the computer of the user. For this purpose, the IP address of the user must remain saved for the duration of the session.
Saving in a log file takes place in order to ensure the functional capability of the website. In addition, the data enables us to optimize the website and to ensure the security of our IT systems. IP addresses contained in the log entries are not combined with other data inventories, unless there are concrete indicators of a disruption to the correct operation.
The recording of active network components also enables us to ensure the security of the IT systems.
These purposes also represent our legitimate interest in the data processing in accordance with Article 6 Paragraph 1 Letter f) GDPR.
The legal basis for the temporary storage of the data and log files is Article 6 Paragraph 1 Letter f) GDPR.
Should criminal investigations be initiated due to attacks against our IT systems, the data named under 4.1.1 and log files can be passed on to state investigative bodies (for example the police, criminal prosecution authorities).
The same applies if relevant authorities and/or courts make inquiries of the University and we are obliged to respond to these.
The data will be deleted once it is no longer necessary for the purpose for which it was gathered. In case of the recording of data for provision of the website, this is the case when the respective session has come to an end.
The storage of the data in log files is completely deleted after fourteen days.
The recording of data for provision of the website and the storage of data in log files is absolutely necessary in order to operate the website. Users who do not wish for their data to be processed as described can contact the University via alternative channels (by telephone, in written form, in person) in order to receive corresponding information or carry out actions.
In general, no cookies are generated during visits to the HLRS websites. An exception is necessary when using the “Change Contrast” function, which requires a session cookie.
By activating the Change Contrast function, it is possible to switch the color of all text to black, improving its legibility and our website’s accessibility. When it is first activated, a session cookie (“contrast”) is created, saving a unique ID number. Information is connected with this ID on the server that determines which contrast setting was chosen for the display of web pages. It is necessary that this occur so that the setting is recognized and maintained when visiting other web pages.
Any user data captured to create these technically necessary cookies are not used for the creation of user profiles.
Usage of cookies for these purposes is permitted under the scope of legitimate interest in the processing of personal data according to Art. 6 para. 1 let. f of the DSGVO.
The legal basis for the processing of personal data when using session cookies is Art. 6 para. 1 let. f of the DSGVO.
The recipient of the information contained in the session cookie is exclusively the authorized web server, i.e. the HLRS web server that sets the session cookie.
Session cookies are automatically deleted from your computer when you close your browser.
The session cookie is saved on the user’s computer and is then transferred from it to our web server. This means that you as a user - independent from the requirement of saving the cookie detailed above - have complete control over the usage of cookies. By changing the settings in your internet browser, you can deactivate or restrict the passing of session cookies. Cookies that have already been saved can be deleted at any time. This can also be done automatically. If the session cookie for our website is deactivated, the contrast setting that you have selected will not be retained when visiting other web pages.
Our website uses the open source software tool Matomo (formerly PIWIK).
When individual pages on our website are visited, the following data are temporarily saved:
The software used for these purposes runs exclusively on the servers of our website. The saving of data occurs only there. Any data collected are not forwarded to other third parties.
Personal data are only processed temporarily insofar as the complete IP address is processed until it is stored in temporary memory.
The processing of users‘ personal data enables us to analyze the behavior of our users when navigating our website. Evaluating the data we collect enables us to gain an understanding of the usage of components of our website. This helps us to continually improve our website’s usability and assess how well it addresses the interests of our visitors. These purposes are permitted as a legitimate interest in the processing of data as specified in Art. 6 para. 1 let. f of the DSGVO. The users’ interest in protecting their personal data is addressed through the anonymization of their IP addresses.
The legal basis for the temporary processing of the users' personal data until the shortened IP address is stored is Art. 6 (1) let. f of the DSGVO.
For this purpose, please contact us via email: recht(at)hlrs.de.
The competent supervisory authority is the Landesbeauftragte für den Datenschutz und die Informationsfreiheit Baden-Württemberg.

On our website, components of various third-party providers are used in order to provide additional content. For example, these include YouTube videos, as well as share and like buttons of social media platforms.
If we were to directly integrate the social medial elements made available by the third-party providers into the website, then when loading the website in which they are integrated, the URL of the website which has just been loaded, the IP address and any other information (for example browser type) would be transferred to the third-party provider and cookies may be set by the third-party provider also. This would also happen if you are not registered with the third-party provider or are a member of it.
If you were also logged into the third-party provider when accessing the website, it would be able to assign additional information to your user account (for example which video you are accessing, which commentary you submit and what information you share etc.).
Therefore, it is the case that social media elements of third-party providers are not directly integrated into our websites. Rather, solutions are used which only establish a connection to the server of the third-party provider once the social element has been intentionally clicked on and only then is the associated data processing carried out.
Please bear in mind that the data processing which is carried out as a result is outside of the area of control of the university and the data protection provisions of the third-party providers must be observed.
You can find some of the data protection provisions here:
Should you not agree to data processing by the third-party provider as described above, please do not click on the social media element.
This website uses the service FlipHTML5 to enable visitors to flip through publications (e.g., our Annual Report) using an embedded player. In order for the browser to display this content, the providers of FlipTML5 must access users’ IP addresses. We have no influence on external uses of these IP addresses.
Within the scope of a business relationship, project, etc. (e.g. contract to provide computing time, or other contracts, grant agreements, consortium agreements, collaboration agreements, privacy agreements, statements of intent, etc.) you must provide any personal data that are necessary for the establishment and execution of a business relationship and the fulfillment of any associated contractual requirements, or that we are required to collect according to law.
Without these data, we must typically reject the signing of a contract and the execution of any associated activities, or will not be able to execute the requirements of an existing contact, including the possibility that it must be ended.
This Privacy Notive is immediately valid and supersedes all prior statements. Further developments may make it necessary to revise this Privacy Notice. We reserve the right to change the Privacy Notice at any time with future effect, and recommend that you stay up-to-date with the current Privacy Notice. The Privacy Notice is linked in the footer of the website www.hlrs.de.
The German version of this Privacy Notice is the only binding and enforceable version of this Statement.
