Website of the House of Representatives of the Dutch Parliament
NL

Tweedekamer.nl is the website of the House of Representatives, the lower house of the Dutch Parliament. Homepage scan: 50 requests, 5 domains. The configuration is exemplary. The House runs its web statistics on its own Piwik PRO platform account, with requests routed through its own proxy subdomain — meaning the data first passes through the parliament's own domain. Requests go out without a visitor identifier, and not a single cookie was set during the session. The scan shows no Google Analytics, no Facebook, no advertising, no session recording, and no third-party commercial trackers. No violations were recorded.

Who receives the data

There are no third-party recipients.

A full banner for the statistics is not required here: it runs through the site’s own subdomain, without a visitor identifier in requests and without cookies. This is consistent with an anonymized mode exempt from consent. Not a single cookie was set during the entire session.

Only anonymized in-house statistics. Before any interaction, the House’s web statistics fire through its own subdomain, without cookies and without a visitor identifier. The scan contains no Google analytics, no advertising domains, no social plugins, and no session recording.

Conclusion

Tweedekamer.nl is a model of a restrained configuration for a legislative body. Web statistics run on the platform’s own account, routed through its own proxy subdomain — a more privacy-friendly setup where data passes through the parliament’s own domain — without cookies and without a visitor identifier. There is no third-party advertising, no Google analytics, no social media pixels, and no session recording whatsoever. The key takeaway for the reader: the lower house of parliament can manage with its own anonymized statistics, and here that is achieved neatly, through its own infrastructure and without a single third-party tracker. No violations were recorded.
