twon-project.eu is the website of the EU-funded research project TWON (Twin of Online Social Networks, 2023–2026). It is a purely static website that is kept as an archive of the project’s results.

  • The website is operated on servers of FZI in Germany. No external hosting provider or content delivery network is used.
  • The website does not use cookies, no tracking or analytics tools and no third-party content: all fonts, images and scripts are delivered from this server. No data is passed on to third parties such as Google, LinkedIn or other social networks while you browse this website.
  • There are no contact forms, comment functions or newsletters.

4. Visiting the website

When you access the website, your browser automatically transmits technical information to our web server, in particular your IP address, the date and time of the request, the requested page or file, the referring website (referrer), and the browser and operating system used (user agent). This data is technically necessary to deliver the website to you and to ensure the security and stability of our systems.

We do not store access logs for this website. Error and warning messages of the web server may contain the IP address of the request concerned; they are only used to analyse technical faults or attacks and are overwritten automatically by log rotation.

The legal basis is Art. 6 (1) (f) GDPR. Our legitimate interest lies in the secure and reliable provision of the website. The data is not used to identify you or to create user profiles.

5. Contacting us by e-mail

If you contact us or one of the researchers named on this website by e-mail, we process your e-mail address and the information you provide in order to answer your enquiry. The legal basis is Art. 6 (1) (f) GDPR (our legitimate interest in answering enquiries) or, if your enquiry aims at concluding a contract, Art. 6 (1) (b) GDPR. We delete the data once it is no longer required for processing your enquiry, unless statutory retention obligations apply.

Please note that many e-mail addresses on this website belong to researchers at other partner institutions of the TWON consortium. If you contact them, the respective institution is responsible for processing your data.

This website contains links to external websites, for example to partner institutions, publishers, code repositories, demonstrator tools hosted by project partners, and social networks such as LinkedIn. Data is only transmitted to these providers once you click on such a link and leave this website. The data protection provisions of the respective provider apply there.
