Indicators of GDPR non-compliance

GDPR Art. 6(1)(a), Art. 13, TKG § 165

webanalytik.oeh.ac.at/webanalytik.js loads at 590 ms and sends a tracking ping (idsite=5) at 755 ms — without consent and without a consent banner. The privacy policy does not mention Matomo or the site's web analytics.

Context

ÖH (Österreichische Hochschüler:innenschaft) is the Austrian students’ union with mandatory membership for all students. WordPress + WooCommerce. HAR: 123 requests, 3 domains. The privacy policy is detailed — covering the shop, newsletter, notice board, forums, and wahlportal.

Matomo without declaration

webanalytik.oeh.ac.at — self-hosted Matomo on an ÖH subdomain, fires at +590 ms. The policy describes Hetzner as the hosting provider and ActiveCampaign for email, but does not mention the site’s web analytics at all. Data stays within ÖH’s infrastructure — architecturally correct. But firing before consent and the absence from the policy constitute a violation.

A detailed policy, but with a gap

ÖH has put significant effort into documentation: 14+ sections, legal bases for each operation, a DPO with contact details. Against this backdrop, the missing web analytics section looks like an oversight rather than deliberate concealment.

Conclusion

A students’ union that represents students’ interests on data protection matters runs a tracker without consent and without declaring it in its own privacy policy.
