§ 2 General information on data processing and its purpose

We process the personal data of our users only to the extent necessary to provide a functioning website and its functionalities.

The following personal data is collected and stored within the system:

Master Data

Within the scope of user authentication the following personal data is collected and processed:

  • User name
  • E-Mail

Registration of the user is required for the provision of certain content and services within nopaque.

Protocol Data

In general, when a website is visited, for technical reasons information is automatically sent from the browser to the server and stored there in access protocols. When using a web application, additional protocol data is also generated, which is necessary for tracking technical errors. This information includes:

  • IP address
  • User account
  • Complete HTTP request URL
  • HTTP action (e.g. GET: call up a page, POST: send form data)
  • Access status (HTTP status code)
  • data volume retrieved
  • Date and time of the action
  • User-Agent string

Locally logged data will be used by the development team in order to debug and improve tools. This data can only be viewed by the technical administration and by the employees responsible for the nopaque platform. Data is stored for seven days to ensure proper technical operation and to find the cause of errors and is deleted afterwards.

Logged data may be used to understand how researchers are using the nopaque platform. To be able to use the data for research purposes, we reserve the right to store it in an anonymous and aggregated form for a longer period of time (up to two years after completion of the SFB 1288 INF project).


Browsers store so-called cookies. Cookies are files that can be stored by the provider of a website in the directory of the browser program on the user's computer. These files contain text information and can be read again by the provider when the page is called up again. The provider can use these cookies, for example, to always deliver pages in the theme selected by the user.

The storage of cookies can be switched off in the browser settings or provided with an expiry time. By deactivating cookies, however, some functions that are controlled by cookies can then only be used to a limited extent or not at all.

NOPAQUE uses cookies for the following purposes:

  • Recognition of a user during a session in order to assign personal content and other user-defined settings.
  • Login Script with ‘Remember Me’ feature allows the user to preserve their logged in status. When the user checks the Remember Me option, then the logged in status is serialized in the session and stored in cookies in an encrypted way.
Content Data

The content data includes all data that is entered or created by users themselves in the system. This data is listed here because it is assigned to individual authors and may contain personal data. This may include: uploaded files, images, texts or other media files. Please note that files and scans submitted to NOPAQUE are stored in order to allow persistent access during a work session and between work sessions.

According to § 4 paragraph 2 of the General Terms of Use for the use of NOPAQUE at Bielefeld University, the users themselves are responsible for the content they post and must comply with the legal provisions of data protection. This includes in particular the deletion of personal data that may no longer be processed.

§ 3 Legal basis of the data processing

The legal basis for the processing of personal data for user authentication is Article 6 (1) letter e GDPR. The processing is carried out within the framework of the fulfilment of the tasks of Bielefeld University in accordance with HG NRW (NRW Higher Education Act), if necessary in connection with an order of the university to be named or by a special law, e.g. University Statistics Act, State Civil Servants Act, Staff Representation Act, Equal Opportunities Act.

The collection of personal data for user authentication is based on the consent of the data subjects as stated in Article 6 (1) letter a GDPR. The legal basis for the transmission of personal data is Article 6 (1) letter c GDPR.

§ 4 Data transmissions

Your personal data, which are processed by Bielefeld University for the purposes mentioned under 2. will not be transferred to third parties.

In individual cases, data may also be legally transmitted to third parties, for example, to law enforcement authorities for the investigation of criminal offences within the framework of the Code of Criminal Procedure (StPO). If technical service providers are given access to personal data, this is done on the basis of a contract in accordance with Article 28 GDPR.
