wohnbauforschung.at

Vienna Housing Research Portal, MA 50

Vienna's housing research portal — 42 requests, 1 domain. Zero external requests. But the privacy policy describes Google Analytics with an opt-out scheme and treats the mere fact of visiting the site as consent — a classic pre-GDPR pattern.

Request timeline

All 42 requests go to www.wohnbauforschung.at. No external requests — jQuery, Bootstrap, Font Awesome, and other libraries are hosted locally under /lib/.
Session total
Google Analytics did not appear in the HAR. It may be disabled or inactive on the current version of the site — but the policy still describes it as active.

Declared versus actual

✓ Google Analytics — declared in the policy, absent from the HAR — declared

Indicators of GDPR non-compliance

Context

wohnbauforschung.at is the City of Vienna’s housing research portal, operated by UIV Urban Innovation Vienna GmbH on behalf of MA 50 (Wiener Wohnbauförderung). HAR: 42 requests, 1 domain.

Local infrastructure

42 requests — all to www.wohnbauforschung.at. No external dependencies. jQuery, Bootstrap, Font Awesome, Lightbox — all hosted locally under /lib/. Apache 2.4.67 on Debian. Zero cookies, zero external requests.

A policy from the past

Google Analytics is declared, but did not appear in the HAR — it may in fact no longer be active. Yet the privacy policy describes it as an active tool — and does so using a scheme that became outdated with the introduction of GDPR in 2018: consent is deemed to arise from the mere fact of visiting the site (“Nutzer dieser Website stimmen den Bestimmungen zum Datenschutz zu”), and instead of opt-in, an opt-out via a Google browser plugin is offered. No banner, no CMP, no Art. 6(1)(a) legal basis.

Conclusion

In practice, this is a clean HAR — one domain, zero trackers. On paper, the privacy policy describes Google Analytics using a pre-compliant consent scheme. If Google Analytics is ever reactivated, it will run without any user consent — because the policy already “permits” it.

Evidence

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.
