Indicators of GDPR non-compliance

GDPR Art. 5(1)(a); TDDDG § 25(1)

etracker's e.js loads at +111 ms, with a tracking request to www.etracker.de/cntcc at +278 ms — with no preceding consent banner. The policy justifies this via Art. 6(1)(f) (legitimate interest) and declares a cookieless mode by default. Nonetheless, browser, URL, and user-behavior data goes to etracker with no prior choice. The policy does not reference TDDDG.

Context

DIHK (Deutscher Industrie- und Handelskammertag) is the federal association of 79 German chambers of industry and commerce, representing roughly 3.5 million businesses. CoreMedia CMS, Varnish. HAR: 34 requests, 3 domains.

At +111 ms, code.etracker.com/code/e.js loads (account ID 1BEWo9). At +178 ms — t.js with a version and account identifier. At +278 ms — www.etracker.de/cntcc, carrying the full page URL (pagename=https://www.dihk.de/) and a timestamp. There is no consent banner.

The policy declares etracker via Art. 6(1)(f) DSGVO (legitimate interest) and describes a cookieless mode by default: data is processed in Germany, and etracker is certified under the ePrivacyseal. Whether Art. 6(1)(f) can lawfully be used for web analytics without consent remains a matter of debate in supervisory practice: the DSK (Datenschutzkonferenz) has, in a number of positions, pointed to the need for consent. The policy does not reference TDDDG, which is itself a gap for the website of a German organization that uses cookies and similar technologies.

CSP-Report-Only: byside.com and coremedia.cloud

The Content-Security-Policy-Report-Only header (not enforced) allows *.engagement.coremedia.cloud and *.byside.com. byside is a LiveChat and customer engagement platform (a Portuguese company owned by Nuvei). engagement.coremedia.cloud refers to CoreMedia CMS’s cloud services. Neither domain is active in the HAR — the integrations are apparently planned or being tested. Neither is mentioned in the policy.

Epilogue — local

The Epilogue v17 typeface (Regular, Medium) — two woff2 files from /resource/crblob/. Epilogue was designed by typographer Tyler Finck (Etcetera Type Company) and is distributed via Google Fonts, yet DIHK hosts it locally. No Google Fonts.

Conclusion

www.dihk.de has one violation: etracker is active before the banner, based on legitimate interest — a legal basis that is disputed, and the policy does not reference TDDDG. The architecture is otherwise minimalist: no GTM, no advertising pixels, no external CMP.

I visited the website dihk.de 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) etracker's e.js loads at +111 ms, with a tracking request to www.etracker.de/cntcc at +278 ms — with no preceding consent banner. The policy justifies this via Art. 6(1)(f) (legitimate interest) and declares a cookieless mode by default. Nonetheless, browser, URL, and user-behavior data goes to etracker with no prior choice. The policy does not reference TDDDG.
