- Data Protection Officer -
Clausthal University of Technology (TU Clausthal) processes personal data of website users only as necessary for the operation of a functioning website, its contents and services. The processing of personal data is generally subject to the consent of the user. Exempt are cases in which the consent could not previously be obtained due to factual reasons and in which data processing is permitted by legal regulations.
Legal basis for the processing of personal data
Should the processing operations of personal data require consent of the data subject, art. 6 subpara. 1 lit. a EU General Data Protection Regulation (GDPR) serves as legal basis.
For the processing of personal data for the performance of a contract, with the data subject being an involved party, art. 6 subpara. 1 lit. b GDPR serves as legal basis. This includes data processing conducted for the implementation of pre-contractual measures.
Should the processing operations of personal data be required for TU Clausthal to comply with legal requirements, art. 6 subpara. 1 lit. c GDPR serves as legal basis.
Should the processing of personal data be required due to vital interests of the data subject or another natural person, art. 6 subpara. 1 lit. c GDPR serves as legal basis.
Should the processing be required to carry out a task in the public interest or in the exercise of official authority vested in the controller, art. 6 subpara. 1 lit. e GDPR in conjunction with art. 3 of the Lower Saxony Data Protection Act (NDSG, Niedersächsisches Datenschutzgesetz) serves as legal basis.
Type and scope of the collected data
When accessing the websites of TU Clausthal, our systems automatically collect the following data:
- IP-address of the user’s computer,
- information on the browser type and version,
- the user’s operating system (name and version),
- date and time of access,
- the previous website (referrer) from which the user’s system accessed the website,
- documents retrieved by the user’s system.
This data will also be stored in the logfiles of our systems. This data is not stored in connection with other personal user data. The storage takes place on site of Clausthal University of Technology in Clausthal-Zellerfeld, only using internal infrastructure.
For the temporary storage of data and logfiles art. 6 subpara. 1 lit. e GDPR in conjunction with art. 3 of the Lower Saxony Data Protection Act (NDSG) serves as legal basis.
Data storage period
The temporary storage of the IP-address by the system is essential to provide the user’s computer with requested documents. Thus, the user’s IP-address needs to be saved for the session duration.
The storage in logfiles is necessary to ensure the website functionality. This data also serves to optimize the website and to ensure the IT-system security. The data will not be used for marketing purposes.
The data will be deleted once it is no longer required to fulfill the purpose of its collection. For data collection for website operation this is the case once the respective session was terminated.
Data stored in logfiles is generally deleted after seven days. Storage for a longer period is only intended for technical and legal purposes.
Opportunity to object
Collection of data and storage in logfiles is essential for the provision and operation of the website. Thus, the user shall not have an opportunity to object.
The web analytics software Matomo (formerly: “PIWIK") of the provider InnoCraft Ltd., 150 Willis St, 6011 Wellington, New Zealand, is used on TU Clausthal websites. This open-source software analyzes the web presence of TU Clausthal. The program is operated on TU Clausthal servers and thus the collected analysis data is not disclosed or transmitted to third parties. The legitimate interests of TU Clausthal are the analysis and optimization of its web presence, and marketing purposes, for which art. 6 subpara. 1 lit. f GDPR in conjunction with art. 3 of the Lower Saxony Data Protection Act (NDSG) serves as legal basis. The software collects and evaluates the following data if not objected by the user:
- IP-address, anonymized by shortening
- Cookie to recognize different visitors
- Previously visited URL (referrer) if transmitted by the browser
- Name and version of the operating system
- Name, version and language settings of the browser
- visited URLs on this website
- times of website access
- monitor resolution and color depth
- technologies and formats supported by the browser (e.g. cookies, Java, Flash, PDF, Windows Media)
Complying with data minimization, an automated anonymization function is run by the software Matomo which shortens the IP-address by two bytes leading to a pseudonymized analysis of user behavior. It is not possible for TU Clausthal to link your user profile to you or your internet connection. For data collection, Matomo stores a cookie on your terminal via your web browser. This cookie is valid for 6 months. These cookies, inter alia, enable the identification of the web browser so that the number of different users of the website can be monitored. Should you not consent to the processing, you can disable the storage of cookies in the settings of your web browser. In addition, you can always subsequently adapt the analysis of your user behavior by our cookie banner.
ReadSpeaker is a text-to-speech software for web contents. If you click the button “Listen”, the selected text will be transmitted via your IP to the ReadSpeaker-server where the audio file will be generated during the streaming process and sent back to your IP. After transmitting the audio file, the process and the IP-address of the user will be deleted from the ReadSpeaker-server immediately. ReadSpeaker does not collect or store personal data. All services are operated from Europe (Sweden). When using ReadSpeaker-functions, technical cookies are stored on the terminal to save the user settings (highlighting of settings, font size etc.). After the session, or depending on the selected function, the cookies will be stored for a maximum period of 30 days. If the ReadSpeaker-function is not activated, no cookies will be stored on your terminal when visiting this website. Your consent to the use of ReadSpeaker as laid down in art. 6 subpara. 1 lit. a GDPR serves as legal basis. Please see the information on the withdrawal of consent in the data protection regulation.
