Review a Data Processing Agreement against your UK GDPR Art.28 DPA playbook — auto-detects whether you're processor or controller and applies the right half of the playbook. Checks Art.28 mandatory provisions, sub-processor chain, international transfer mechanisms (IDTA / UK Addendum / adequacy), and privacy notice consistency. Use when the user says "review this DPA", "check this data processing agreement", "customer sent their DPA", "is this DPA okay", or attaches a DPA / processor agreement. Geographic scope: United Kingdom.
