Summary

The Norwegian Data Protection Authority (DPA) has fined Xandr Inc. EUR 8,600,000 for unlawfully processing sensitive personal data of Grindr users. Xandr, acting as a joint controller, processed users' advertising IDs and IP addresses without a valid legal basis, specifically failing to obtain explicit consent for processing data concerning sexual orientation, which is considered special category data under GDPR. The DPA found Xandr's infringements to be at least negligent and of high seriousness, emphasizing that accountability cannot be outsourced.

The lesson from this incident

Full lesson

Xandr processed sensitive personal data — including advertising IDs, IP addresses, and implied sexual orientation — of Grindr users without a valid legal basis, violating GDPR's strict requirements for explicit consent when handling special category data. As a joint controller in the advertising ecosystem, Xandr inherited accountability for lawful data processing but failed to establish adequate consent mechanisms or verify the legitimacy of data received through the supply chain. The Norwegian DPA's finding of negligence underscores that relying on upstream partners to handle consent does not absolve a data controller of its own legal obligations. This case illustrates how ad-tech supply chains create compounding compliance risks where sensitive data flows across multiple parties with insufficient oversight. The €8.6M fine serves as a stark reminder that accountability in data processing cannot be delegated.
