Data protection

This data protection declaration informs you about the type, scope and purpose of the processing of your personal data when using the web offers of the German Stroke Trials Network (GSTN) (https://www.germanstroketrialsnetwork.deincluding subdomains).


1. Data processed, purpose and duration of processing

1.1 Processing of general information when visiting our website

When accessing the website and its content, personal data is only processed to the extent technically necessary (in particular: IP address, name of the file accessed, date and time of access, browser type and version, your operating system, the webpage from which you reached us). This information is technically necessary in order to deliver the contents of our website requested by you without any problems. It is stored regularly when you access a website. Your data is processed in particular for the following purposes:

  • Ensuring the use of and connection to the GSTN web offer,
  • ensuring and evaluating system security and stability, and
  • or other administrative purposes.

The processing of your personal data is based on our legitimate interest arising from the aforementioned data collection purposes (Art. 6 (1) f) DSGVO). We do not assign this data to specific persons and do not combine it with other data sources. The only recipients of the data is the UKE and our order processors.

The server logs are anonymised daily and deleted after 4 weeks. This data is not statistically evaluated, but can be used for error analysis if necessary.


1.2 Use of cookies

The web offers of the GSTN use – like many other websites – so-called “cookies”. Cookies are small text files that are transferred from a server to your hard drive. Data is stored in these cookies on your computer (etc.).

Cookies cannot be used to start programmes or transfer viruses to a computer. The information contained in cookies can be used to facilitate your navigation and to enable the websites to be displayed correctly.

Under no circumstances will the data we collect be passed on to third parties or linked to personal data without your consent.

Of course, you can also view our website without cookies. Internet browsers are regularly set to accept cookies. In general, you can deactivate the use of cookies at any time via the settings of your internet browser. Please use the help functions of your internet browser to find out how to change these settings. Please note that individual functions of our website may not work if you have deactivated the use of cookies.


2. Use of privacy-protecting techniques

2.1 Do Not Track

You can activate “Do Not Track” in your internet browser to partially reduce profiling on the internet. Do Not Track (DNT) signals to a website or web application that it does not wish to create a usage profile about the user’s activities. Of course, the GSTN web offer is designed to recognise and observe corresponding settings.


2.2 SSL encryption

In order to protect the security of your data during transmission between your computer and the UKE website, the UKE uses state-of-the-art encryption procedures (e.g. SSL) via HTTPS.


2.3 Integrated third-party content

The UKE is not responsible for the processing of data collected by third-party providers and makes only very sparing use of the integration of content from other providers.


3. Your data subject rights

You are entitled to so-called data subject rights, i.e. rights that you can exercise as a person affected in an individual case. You can assert these rights against the UKE.

You have the right to information about the personal data stored about you in accordance with Art. 15 DSGVO. If you discover that incorrect data relating to you is being processed, you may, under certain conditions, request rectification in accordance with Art. 16 DSGVO. Incomplete data must be completed taking into account the purpose of the processing. As far as the requirements of Art. 17 DSGVO are fulfilled, in particular the data is no longer required for the original purpose and the retention periods have expired, you can request that we delete the data. According to Art. 18 DSGVO, you may be able to demand that UKE restricts further processing of the data. This means that although your data will not be deleted, it will be marked to block it from further processing. Insofar as the processing of your patient data is based on a public or legitimate interest within the meaning of Art. 6(1)(e), (f) DSGVO, you may object to the processing on the grounds of your particular personal situation in accordance with Art. 21 DSGVO.
