Schrems II and analytics transfers

Schrems II is the 2020 Court of Justice of the EU judgment that invalidated the EU-US Privacy Shield and held that Standard Contractual Clauses remain valid only with a case-by-case assessment of the destination country's surveillance laws. Its reasoning later drove regulator decisions against certain US-hosted analytics. This page explains the ruling and its analytics impact.

What the court decided

In July 2020, the CJEU ruled in Case C-311/18 (Schrems II) that the Privacy Shield adequacy decision was invalid, because US surveillance law did not provide EU individuals with protections essentially equivalent to EU law and lacked adequate redress. It upheld SCCs in principle but stressed that exporters must verify, case by case, whether the destination country undermines them — and add supplementary measures where it does.

The judgment shifted responsibility onto data exporters to actively assess each transfer.

Impact on analytics

Following Schrems II, several European data protection authorities found specific deployments of US-hosted analytics unlawful where data could be exposed to US authorities and supplementary measures were inadequate. That accelerated interest in EU-hosted, first-party, and proxied measurement. The later EU-US Data Privacy Framework created a new adequacy route, but the assessment discipline Schrems II introduced remains relevant.

How it appears in analytics and logs

A history of regulator actions against US-hosted analytics traces to Schrems II: SCCs alone were judged insufficient without effective supplementary safeguards.

Diagnostic use case

Understand why transferring EU analytics data to the US now requires a transfer assessment and possibly supplementary measures, not just a signed contract.

What WebmasterID can help detect

First-party, regional measurement minimises the cross-border transfers that Schrems II made harder to justify.
