The Chamber of Hungarian Architects (MÉK, official portal mek.hu) — 67 requests, 3 domains. There is no consent banner on the page: Google Tag Manager and Google Analytics fire on load and register the visit before any choice is made, transmitting the IP address to Google (USA). The cookie policy, meanwhile, declares that processing via cookies is based only on consent.

GA4 g/collect carrying the page URL. No Consent Mode signal (gcs) present.

- Google Analytics 4 (region1.google-analytics.com, G-7299H38393) — registers the visit prior to consent
- Google Tag Manager / gtag (G-7299H38393)
Indicators of GDPR non-compliance
- GDPR Art. 6 + ePrivacy (Hungarian implementation) — analytics prior to consent, with no bannerOn page load, without any consent banner whatsoever, Google Tag Manager fires (at +279 ms), after which Google Analytics 4 (identifier G-7299H38393) sends a visit-registration hit request to region1.google-analytics.com/g/collect carrying the page URL. No consent management platform or consent banner is present in the capture; the GA request carries no Consent Mode signal (gcs). The Chamber's cookie policy states directly that the legal basis for processing via cookies is the data subject's consent. In fact, however, analytics is activated before any choice is made, and the visitor's IP address is transmitted to Google (USA).
Context
mek.hu is the official professional portal of the Chamber of Hungarian Architects (Magyar Építész Kamara, MÉK), a body carrying out statutorily assigned public-administrative tasks in the field of architectural practice and providing information to practicing architects. The data controller is MÉK. The site is served by an Apache server. Capture: 67 requests, 3 domains, recorded in a clean browser.
Direct Recipients of Data (prior to consent)
Google (USA) — the visitor’s IP address via Google Analytics and Google Tag Manager.
Declared versus Actual
The Chamber of Architects’ cookie policy states the legal basis directly: data processing via cookies is carried out on the basis of the data subject’s consent (GDPR Art. 6(1)(a)), with consent withdrawable through browser settings. The policy separately names Google Analytics as the statistics tool in use and states that the Chamber does not process personal data via cookies.
The capture reveals a different sequence. At +279 ms, immediately on page load, Google Tag Manager connects (identifier G-7299H38393). Google Analytics 4 then sends a visit-registration hit request — a call to region1.google-analytics.com/g/collect carrying the page address. That is, the visit is actually registered. No consent management platform or consent banner is present on the page at all, and the Google Analytics request carries no Consent Mode signal (the gcs parameter): consent is not collected, and this is not signaled to Google. The visitor’s IP address is, meanwhile, transmitted to Google (USA).
There are no other trackers — Facebook, advertising pixels, font services — in the capture. No cookies are set in the captured headers (Set-Cookie is zero). The discrepancy is direct: the policy promises analytics only with consent, while in fact it activates by default, without a banner and without a choice by the user.
Timing Relative to Consent
Google Tag Manager fires at +279 ms; GA4 visit registration at +5601 ms. Both occur before any choice is made by the user. There is no consent banner on the page that could have preceded any of this. No consent was given during the session, and there is no Consent Mode signal in the Google Analytics request.
What Cannot Be Asserted from This Capture
The capture covers the home page in its pre-consent state. Set-Cookie is absent from the captured headers; the conclusion is drawn from the fact of GTM loading and from the Google Analytics visit-registration hit request, rather than from cookie headers. Google may use edge nodes within the EU; the conclusion drawn therefore concerns the recipient’s corporate affiliation (a US company), not the location of the node. Server-side processing is not visible in a browser-based capture.
Conclusion
The official portal of the Chamber of Hungarian Architects launches Google Tag Manager and Google Analytics immediately on page load, without any consent banner, and actually registers the visitor’s visit — with the Google Analytics request lacking even a Consent Mode signal. The Chamber’s cookie policy states directly the opposite: that processing via cookies is carried out only on the basis of the data subject’s consent. The discrepancy between what is declared and what actually occurs here is direct. For the website of a body with public-administrative functions, launching analytics and registering the visit by default, on every visit, and outside any consent mechanism, together with the transfer of the IP address to Google (USA), constitutes a violation of the requirements concerning the legal basis for processing and cross-border transfer. Remedy: implement a consent banner and hold back Google Analytics and Google Tag Manager until actual consent is given, or switch to privacy-preserving self-hosted analytics without data transfer to the USA.

Subject of the complaint I am filing a complaint regarding the processing of my personal data by the website mek.hu. 2. Circumstances I visited the website mek.hu and found indications that the processing of my personal data does not comply with the GDPR. The technical analysis published on gdpru.eu on 29 May 2026 (open methodology, reproducible measurements) documents the following indications: 1) On page load, without any consent banner whatsoever, Google Tag Manager fires (at +279 ms), after which Google Analytics 4 (identifier G-7299H38393) sends a visit-registration hit request to region1.google-analytics.com/g/collect carrying the page URL. No consent management platform or consent banner is present in the capture; the GA request carries no Consent Mode signal (gcs). The Chamber's cookie policy states directly that the legal basis for processing via cookies is the data subject's consent. In fact, however, analytics is activated before any choice is made, and the visitor's IP address is transmitted to Google (USA). Full technical documentation is published at: https://gdpru.eu/en/audits/hu-mek-hu/ 3. Provisions violated GDPR Art. 6 + ePrivacy (Hungarian implementation) — analytics prior to consent, with no banner 4. Request I request that you investigate the violations described and apply the measures provided for in Article 58(2) GDPR. 5. Attachments The full evidence base — the HAR file, its SHA-256 checksum and the quotation from the site's privacy policy documenting the stated contradiction — is published and verifiable at the link in point 2 above.
