— GDPR, Article Article 20

In plain English

This control allows data subjects to request their personal data in a machine-readable format and transfer it to another controller, provided the processing is based on consent or a contract and is automated. In practice, this means you can prove you right consent-level controls on a defined cadence.

Why it matters

GDPR administrative fines reach the greater of €20 million or 4% of global annual turnover. The European Data Protection Board (EDPB) coordinates supervisory-authority enforcement across the EU/EEA, and DPAs publish enforcement decisions citing specific Articles.

This control is rated critical in the source catalogue. Treat gaps here as production incidents in the risk register, not housekeeping.

What an auditor looks for

A DPA or privacy auditor expects: a Records of Processing Activities (RoPA) entry, a documented lawful basis, evidence the Article's data-subject right is operationalised end-to-end, a named DPO contact (where required), and Article 30 records that match what the front-end actually does.

Within Chapter III: Rights of the Data Subject, the assessor will trace your implementation back to the catalogue reference (Article Article 20) and look for objective evidence on the latest two assessment cycles.

How to implement

Policy Management

Docs. Keep each policy in version-controlled Markdown alongside the code that implements it; ship a signed PDF snapshot at each annual review and link the SHA into the SoA.

Operational checklist

  • Right. Document the trigger, the owner and the cadence.
  • Data. Document the trigger, the owner and the cadence.
  • Scope: consent, data portability, controller, rights, data subjects.

Evidence to collect

  • Policy Document. A signed and version-controlled policy / standard / procedure document.

Signed policy or standard documents the safeguard. Focus: Right to data portability.

Common pitfalls

  • Policies that no engineer has read; the version in Confluence drifts from the version that's actually being enforced.

How it maps to other frameworks

Computed from shared tags, control component and key-operation subjects — handy when you are reconciling controls across an audit.
