GDPR Data Flow Diagram

A GDPR data flow diagram maps how personal data enters, moves through, and exits your systems — identifying every actor, process, datastore, and trust boundary. You need one when conducting a Data Protection Impact Assessment (DPIA), responding to a regulator audit, or documenting Article 30 Records of Processing Activities.

Any flow that crosses from an EU trust boundary to a non-EU external actor (such as a US-based analytics vendor or a cloud provider without an adequacy decision) requires a legal basis like Standard Contractual Clauses (SCCs) or Binding Corporate Rules. The diagram flags these boundary-crossing flows automatically so you can prioritize your compliance review.
