Website of Delft University of Technology
NL

Tudelft.nl is the website of Delft University of Technology. Homepage scan: 59 requests, 10 domains. The configuration is exemplary. Among analytics, there is only the private Siteimprove package, running without cookies and anonymized. The remaining external services are functional: an image-delivery network, an accessibility text-to-speech tool, and a consent-collection platform. The scan shows no Google Analytics, no Facebook, no advertising, no session recording, and no third-party commercial trackers. Not a single cookie was set during the session. No violations were recorded.

Context

www.tudelft.nl is the website of Delft University of Technology (TU Delft): information on education, research, and admissions. The data controller is the university. The site is informational.

Scan: 59 requests to 10 domains, homepage, captured in a clean Edge browser without a VPN or ad blocker. The site has a consent-collection platform. The technical stack is restrained.

Who receives the data

There are no third-party commercial recipients.

Among analytics, only the private Siteimprove package runs, without cookies and anonymized. The remaining external services are functional: an image-delivery network, an accessibility text-to-speech tool, and a consent-collection platform. The scan shows no Google Analytics, no advertising networks, no social media pixels, and no session recording.

Yes, the site has a consent-collection platform. That said, the only analytics runs without cookies and is anonymized, and is therefore exempt from consent. Not a single cookie was set during the entire session. The remaining external requests — image delivery and text-to-speech — relate to page functioning and accessibility.

Only cookieless analytics and functional elements. Before any interaction, private cookieless analytics, image delivery, and the text-to-speech tool fire. The scan contains no Google analytics, no advertising domains, no social plugins, and no session recording.

Conclusion

Tudelft.nl is a model of a restrained configuration for a university. The only analytics is private Siteimprove, running without cookies and anonymized, while the remaining external services are functional: image delivery and accessibility text-to-speech. There is no third-party advertising, no Google analytics, no social media pixels, and no session recording whatsoever, and no cookies are set. The key takeaway for the reader: a university can manage perfectly well with cookieless, anonymized statistics alone, and here that is achieved without a single third-party commercial tracker. No violations were recorded.
