Use Article 3 as a separate territorial-scope test. GDPR can apply where processing is in the context of an EU establishment, even if processing occurs outside the Union. It can also apply to non-EU controllers or processors when processing relates to offering goods or services to people in the Union or monitoring their behaviour in the Union.
Record facts that show the link to the Union. For establishment, capture stable EU arrangements and how the processing is connected to those activities. For targeting, capture EU-facing offers such as language, currency, delivery, sales, signup, or service availability. For monitoring, capture tracking, profiling, behavioural analytics, location monitoring, health or lifestyle app telemetry, or similar observation of people in the Union.
