Indicators of GDPR non-compliance
- GDPR Art. 6(1), Art. 5(1)(a)GTM carrying GA4 (G-MDW1S9PQPW) loads at +1234 ms — 1475 ms before Usercentrics appears (+2709 ms). Google Ads (AW-1006368194) activates at +3757 ms via GTM after the banner has loaded, but before any user interaction.
- GDPR Art. 7Usercentrics loads 2.7 seconds after the session begins. By this point, GTM is already active and GA4 is already initialized. Consent is requested after data has actually been transmitted.
- GDPR Art. 13(1)(f), Chapter VGTM, GA4, and Google Ads transmit data to the USA. The transfer mechanism — the EU-US Data Privacy Framework — should be explicitly stated for each recipient.
Context
Zalando SE is Europe’s largest online fashion and footwear retailer, headquartered in Berlin. zalando.ee is the Estonian version of the platform. For GDPR purposes, the data controller for EU users is Zalando SE, and the supervisory authority is the German Berliner Beauftragte für Datenschutz und Informationsfreiheit. HAR: 254 requests, 11 domains.
What has been done correctly
Zalando uses Usercentrics, a serious European CMP, with configuration available in Estonian (translations-et.json). Sentry is deployed on an EU instance (js-de.sentry-cdn.com, Germany) — error data stays within the EU. The site’s own image infrastructure (ztat.net) is used, with no Google CDN or Cloudflare involved for media. Zero Set-Cookie responses — cookies are set only after consent.
The main problem — loading order
GTM carrying GA4 (G-MDW1S9PQPW) loads at +1234 ms. Usercentrics appears at +2709 ms. The gap is 1475 milliseconds.
This means GA4 initializes before the user ever sees the consent banner. Technically, GA4 may withhold sending data until it receives a consent signal from Usercentrics — this depends on the Consent Mode v2 configuration. But the mere fact that the analytics script loads before the banner is itself a violation of the privacy-by-default principle: analytics should not even initialize prior to consent.
After Usercentrics loads, the main GTM container (GTM-T3W9FX) and Google Ads (AW-1006368194) activate via it. The Google Ads collect call (+3963 ms) is transmitted to the USA — this may mean advertising is activated by default without explicit consent, or that Consent Mode treats the loading of Usercentrics as implicit consent.
Sentry EU — the correct choice
This is the second site in the series, after IIZI, where Sentry uses an EU instance. Zalando has gone further — js-de.sentry-cdn.com indicates a CDN with German nodes. A deliberate choice that resolves the issue of data transfer outside the EEA for error monitoring.
Conclusion
Zalando has invested serious effort into compliance: Usercentrics with Estonian localization, Sentry EU, its own media infrastructure. But GTM loads 1.5 seconds before the banner — and that alone is enough to do not comply with the principle of consent preceding processing. The difference between good architecture and correct architecture here lies in the order in which scripts load.
How to verify: download the file and compute its checksum — sha256sum file.har (Linux, macOS) or certutil -hashfile file.har SHA256 (Windows); it must match the one shown. The conclusions apply to the scope of this measurement — see the limitations of the method.
