State Foundation Preserving the Bauhaus School's Heritage

Stiftung Bauhaus Dessau — the state foundation preserving the Bauhaus school's heritage. 81 requests, 3 domains. CookieFirst's no-autoblock mode correctly blocks all trackers before consent. Graebenbach and GraebenbachMono — Bauhaus-designed fonts — served locally. Matomo, YouTube, Meta Pixel — documented, not activated.

Timeline of the leak

+95–118 ms · load
All CSS, JS, images — from www.bauhaus.de. Graebenbach fonts (Regular, Medium), GraebenbachMono (Regular, Light), and the bauhaus.ttf icon font — all local. Swiper, Lottie, Vue.js, Swup — all self-hosted.
+118 ms · CookieFirst JS
www.bauhaus.de/providers/cookiefirst/cookiefirst.js — a CookieFirst wrapper loads locally as a provider.
+161 ms · CookieFirst SDK
consent.cookiefirst.com/consentBanner.no-autoblock.js — the CMP SDK in no-autoblock mode. The banner initializes.
+413 ms · geolocation
edge.cookiefirst.com/prod/location — CookieFirst determines the visitor's country to configure the banner.
No tracking — no-autoblock works
Matomo, YouTube, Meta Pixel, and gomus are not activated. The no-autoblock mode means CookieFirst does not automatically scan and block scripts, but all third-party trackers are wired up with conditional loading on the WordPress side — they do not load without consent. Set-Cookie — zero.

Context

Stiftung Bauhaus Dessau is the state foundation preserving the heritage of the famous 1919–1933 design school. Funded by the federal government and the state of Saxony-Anhalt. It manages the original Bauhaus buildings in Dessau — UNESCO World Heritage sites. WordPress with a custom theme. HAR: 81 requests, 3 domains.

Graebenbach — a Bauhaus typeface

The site uses the Graebenbach typeface (Regular, Medium) and GraebenbachMono (Regular, Light), along with the bauhaus.ttf icon font — all hosted locally. Graebenbach is a modern interpretation of Bauhaus constructivist typography, developed specifically for the digital use of the school’s heritage. No Google Fonts, no Adobe Fonts — typographic independence is maintained.

CookieFirst no-autoblock — an architectural choice

The no-autoblock mode means CookieFirst does not scan the HTML for third-party scripts and does not block them automatically. Instead, all trackers are loaded conditionally: WordPress plugins (Matomo, YouTube, Meta) check for the presence of consent in the CookieFirst cookie before loading. This requires more careful configuration, but yields a more predictable result: not a single stray tracker request appears in the HAR.

Friendly Challenge — a privacy-friendly reCAPTCHA alternative

The site uses friendly-challenge/widget.module.min.js — Friendly Challenge from Friendly Captcha GmbH (Munich). Unlike Google reCAPTCHA, Friendly Challenge sets no cookies and transmits no data to the USA: verification tasks are solved mathematically in the browser with no user identification. Hosted locally (/libs-on-demand/). This is a deliberate choice in favor of privacy-friendly CAPTCHA — part of the site’s overall policy.

A detailed privacy policy

The policy (in English) documents Matomo, YouTube (with SCC and DPF), Meta Pixel, gomus (the ticketing system), CookieFirst, Friendly Challenge, and Hetzner hosting in detail. For each service, the address, legal basis, and data-transfer mechanism are stated. The level of documentation is comparable to BSI’s.

Conclusion

bauhaus.de is the twelfth zero result in the German series in terms of actual active tracking. CookieFirst is technically an external domain, but its loading before the banner is unavoidable — a systemic property of any external CMP. All declared trackers (Matomo, YouTube, Meta) are correctly blocked before consent. A state cultural foundation, not part of the federal ITZBund platform, has built a comparable privacy standard using its own tools.

1. Subject of the complaint
I am filing a complaint regarding the processing of my personal data by the website bauhaus.de.

2. Circumstances
I visited the website bauhaus.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) CookieFirst (Digital Data Solutions B.V., Netherlands) loads at +161 ms without user consent. As a consent management platform, CookieFirst processes data about the user's choice: IP address, a device UUID (b429fc54-f214-47ec-94e1-df385802efef), language, and country (edge.cookiefirst.com/prod/location). This is a standard tradeoff: loading the CMP before consent is technically necessary to display the banner. All other trackers (Matomo, YouTube, Meta) are blocked before consent.

3. Provisions violated
GDPR Art. 13(1)(e)

4. Request
I request that you investigate the violations described and apply the measures provided for in Article 58(2) GDPR.
