Data protection and AI

In short: Anyone processing personal data with AI remains bound by the GDPR: purpose limitation, legal basis, the right of access. What matters is where the data is processed and whether it flows into training.

What it is about

As soon as an AI system handles information about identifiable people — names, emails, customer histories, voice recordings — the GDPR applies. It does not matter whether a human or a machine does the processing.1

The questions to answer

  • Legal basis. On what ground may the data be used: contract, consent, legitimate interest?1
  • Purpose. Is the AI use covered by the purpose for which the data was collected?
  • Where is it processed? Inside the EU, or in a third country such as the USA (then under the EU–US Data Privacy Framework or other safeguards)?3
  • Training. Does the provider use your inputs to train its models? Business plans usually allow switching this off.
  • Rights. Can you answer requests for access and deletion?
  • Impact assessment. High-risk processing needs a data protection impact assessment (Article 35).1

Personal data inside models

The European Data Protection Board stated in December 2024 that an AI model trained on personal data is not automatically anonymous; this has to be assessed case by case.2

In practice

  • Use business versions of AI tools with a data processing agreement.
  • Keep confidential and personal data out of public tools unless a rule allows it.
  • Tell customers when AI processes their data.
  • Document decisions — it is the first thing an authority asks for.
