General information on data processing
Clausthal University of Technology processes the personal data of website users only to the extent necessary to provide a functional website and its content and services. As a rule, personal data is only processed with the user's consent. An exception applies in cases where prior consent cannot be obtained for factual reasons and the processing of the data is permitted by law.
Legal basis for the processing of personal data
Insofar as we obtain the consent of the data subject for the processing of personal data, Art. 6 para. 1 lit. a EU General Data Protection Regulation (GDPR) serves as the legal basis.
When processing personal data that is necessary for the performance of a contract to which the data subject is a party, Art. 6 para. 1 lit. b GDPR serves as the legal basis. This also applies to processing operations that are necessary to carry out pre-contractual measures.
Insofar as the processing of personal data is necessary to fulfill a legal obligation to which our company is subject, Art. 6 para. 1 lit. c GDPR serves as the legal basis.
In the event that vital interests of the data subject or another natural person require the processing of personal data, Art. 6 para. 1 lit. d GDPR serves as the legal basis.
If processing is necessary for the performance of a task carried out in the public interest or in the exercise of official authority vested in the controller, the legal basis is Article 6(1)(e) GDPR in conjunction with Section 3 of the Lower Saxony Data Protection Act (NDSG).
Websites of the TU Clausthal
Type and scope of data collected
Each time the Clausthal University of Technology website is accessed, our systems automatically collect the following data
- IP address of the user's computer,
- Information about the browser type and version used,
- The operating system (name and version) of the user,
- Date and time of access,
- The source website (referrer) from which the user's system accessed the website,
- Documents retrieved by the user's system.
The data is also stored in the log files of our systems. This data is not stored together with other personal data of the user. Storage takes place at the Clausthal University of Technology site in Clausthal-Zellerfeld exclusively on our own infrastructure.
The legal basis for the temporary storage of data and log files is Art. 6 para. 1 lit. e GDPR in conjunction with § 3 NDSG.
Duration of data storage
The temporary storage of the IP address by the system is necessary to enable the delivery of requested documents to the user's computer. For this purpose, the user's IP address must remain stored for the duration of the session.
The data is stored in log files to ensure the functionality of the website. In addition, the data is used to optimize the website and to ensure the security of the information technology systems. The data is not analyzed for marketing purposes.
The data is deleted as soon as it is no longer required to achieve the purpose for which it was collected. In the case of the collection of data for the provision of the website, this is the case when the respective session has ended.
If the data is stored in log files, this usually occurs after seven days. Longer storage is only intended for technical and legal purposes.
Possibility of objection
The collection of data for the provision of the website and the storage of data in log files is absolutely necessary for the operation of the website. Consequently, the user has no option to object.
Web analysis by internal systems or external providers / use of cookies
The web analysis software Matomo (formerly: "PIWIK") from the provider InnoCraft Ltd, 150 Willis St, 6011 Wellington, New Zealand, is used on the websites of Clausthal University of Technology. This is open source software that can be used to analyze the use of the TU Clausthal website. The program is operated on TU Clausthal's own servers so that the analysis data collected is not passed on to third parties. The legitimate interest of Clausthal University of Technology lies in the analysis and optimization of its website and in marketing purposes, the legal basis for this is Art. 6 para. 1 lit. e) GDPR in conjunction with § 3 NDSG. The software collects and analyzes the following data, unless you as a user have objected to the analysis
Basic data:
- IP address, anonymized by shortening
- Cookie, to distinguish between different visitors
- Previously visited URL (referrer), if transmitted by the browser
- Name and version of the operating system
- Name, version and language setting of the browser
Additionally, if JavaScript is activated:
- URLs visited on this website
- Times of the page views
- Screen resolution and color depth
- Technologies and formats supported by the browser (e.g. cookies, Java, Flash, PDF, WindowsMedia)
In the interests of data economy, an automatic anonymization function is carried out by the Matomo software, which shortens the IP address directly by two bytes, so that an evaluation of usage behaviour takes place in pseudo-anonymized form. It is not possible for TU Clausthal to link the user profile to you or your internet connection. To collect the data, Matomo stores a cookie on your end device via your Internet browser. This cookie is valid for 6 months. Among other things, the cookies make it possible to recognize the Internet browser so that it can be recorded how many different users have visited the website. If you do not agree to this processing, you have the option of preventing the storage of cookies by changing the settings in your Internet browser. In addition, you can change the analysis of your usage behavior at any time via our cookie banner.
ReadSpeaker
ReadSpeaker is a reading service for Internet content. When you click on the "Read aloud" button, the corresponding text is transmitted via the user's IP to the ReadSpeaker server, where the audio file is generated during the streaming process and sent back to the user's IP. Once the audio file has been transmitted, the process and the user's IP address are immediately deleted from the ReadSpeaker server. ReadSpeaker does not collect or store any personal data. All services are implemented in Europe (Sweden). When using the ReadSpeaker function, technical cookies are stored on the end device to retain the settings selected by the user (highlighting settings, text size, etc.). They are stored after the session or, depending on the function selected, for a maximum period of up to 30 days. If the ReadSpeaker function is not activated, no cookies will be stored on your device when you visit the website. The legal basis for the use of ReadSpeaker is your consent to its use in accordance with Art. 6 para. 1 lit. a. DSVGO. Please note the information on revocation in the privacy policy.
Social media and external advertising
No code elements from social media providers that enable the direct sharing of content from Clausthal University of Technology websites are used. As a result, no access information is shared with social media providers when using the Clausthal University of Technology website.

Our social media presence
We maintain publicly accessible profiles in social networks. The individual social networks we use are listed below. Social networks such as Facebook, Twitter etc. can generally analyze your user behavior comprehensively if you visit their website or a website with integrated social media content (e.g. like buttons or advertising banners). Visiting our social media presences triggers numerous data protection-relevant processing operations. In detail:
If you are logged into your social media account and visit our social media presence, the operator of the social media portal can assign this visit to your user account. However, your personal data may also be collected if you are not logged in or do not have an account with the respective social media portal. In this case, this data is collected, for example, via cookies that are stored on your device or by recording your IP address. With the help of the data collected in this way, the operators of the social media portals can create user profiles in which your preferences and interests are stored. In this way, interest-based advertising can be displayed to you inside and outside the respective social media presence. If you have an account with the respective social network, the interest-based advertising can be displayed on all devices on which you are logged in or have been logged in. Please also note that we cannot track all processing operations on the social media portals. Depending on the provider, further processing operations may therefore be carried out by the operators of the social media portals. For details, please refer to the terms of use and data protection provisions of the respective social media portals.
Legal basis:
Our social media presences are intended to ensure the widest possible presence on the Internet. This is public relations work within the meaning of Art. 6 para. 1 lit. e GDPR in conjunction with Section 3 NDSG. The analysis processes initiated by the social networks may be based on different legal bases, which must be specified by the operators of the social networks (e.g. consent within the meaning of Art. 6 para. 1 lit. a GDPR).
Controller and assertion of rights:
If you visit one of our social media presences (e.g. Facebook), we are jointly responsible with the operator of the social media platform for the data processing operations triggered during this visit. You can assert your rights (information, rectification, erasure, restriction of processing, data portability and complaint) both against us and against the operator of the respective social media portal (e.g. Facebook). Please note that, despite the joint responsibility with the social media portal operators, we do not have full influence on the data processing procedures of the social media portals. Our options depend largely on the company policy of the respective provider.
Storage duration:
The data collected directly by us via the social media presence will be deleted from our systems as soon as you ask us to delete it, revoke your consent to storage or the purpose for data storage no longer applies. Stored cookies remain on your end device until you delete them. Mandatory statutory provisions - in particular retention periods - remain unaffected. We have no influence on the storage period of your data that is stored by the operators of social networks for their own purposes. For details, please contact the operators of the social networks directly (e.g. in their privacy policies, see below).
