Who we are
Our website address is: https://www.photonq.de.
Description and categories of data
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:
- IP address of the accessing computer
- Date and time of the access
- Name, URL and transferred data quantity of the accessed file
- Access status (requested file transferred, not found etc.)
- Browser type and operating system (if transferred by the requesting web browser)
- Website from which the access took place (if transferred by the requesting web browser)
The processing of the data in this log file takes place as follows:
- The log entries are continually automatically evaluated in order to recognize attacks against the web server and in order to be able to respond accordingly.
- In individual cases, i.e. in case of reported disruptions, errors and security breaches, a manual analysis takes place.
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 anonymized after seven days. This takes place by means of shortening the IP addresses.
Consequences of non-provision, right of objection and correction
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.

How long we retain your data

All users can see, edit, or delete their personal information at any time (except they cannot change their username). Website administrators can also see and edit that information.
