Policy changed — see what exactly · 2026-10-13 →

Kadaster.nl is the website of the Dutch Land Registry (the state land registry and property registration authority). Homepage scan: 77 requests, 4 domains. The configuration is exemplary. The only external contact is Kadaster's own web statistics, built on the Piwik PRO platform and configured anonymously. The policy explicitly states that, thanks to the privacy settings applied, consent for these analytics cookies is not required. The scan shows no Google Analytics, no Facebook, no advertising, no session recording, and no third-party commercial trackers. The site has its own cookie banner, and not a single cookie was set during the session. No violations were recorded.

Context

www.kadaster.nl is the website of the Dutch Land Registry (Het Kadaster): the state land registry, registration of real estate and rights to it, and mapping data. The data controller is Kadaster, a government organization. The site is informational and service-oriented.

Scan: 77 requests to 4 domains, homepage, captured in a clean Edge browser without a VPN or ad blocker. The site has its own cookie banner. The technical stack is minimal.

Who receives the data

There are no third-party commercial recipients.

The only external service is Kadaster’s own web statistics, built on the Piwik PRO platform, deployed under the organization’s own account, and configured anonymously. The scan shows no Google Analytics, no advertising networks, no social media pixels, and no session recording.

Yes, the site has its own cookie banner. That said, by design, the analytics does not require consent: the policy explicitly states that, thanks to the privacy settings applied, consent for these analytics cookies is not needed. Not a single cookie was set during the entire session.

Only anonymized in-house statistics. Before any interaction, a single external service fires — Kadaster’s web statistics on the Piwik PRO platform, in anonymized mode and without tracking cookies. The scan contains no Google analytics, no advertising domains, no social plugins, and no session recording.

Conclusion

Kadaster.nl is a model of a restrained configuration for a government registry. The only external service is its own web statistics on the Piwik PRO platform, configured anonymously such that, per the explicit statement of the policy, consent is not required for it. 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 government registry can manage perfectly well with its own anonymized statistics, and here that is achieved without a single third-party commercial tracker, with the anonymization confirmed by the policy. No violations were recorded.
