Is ChatGPT GDPR-Compliant?
The honest answer: it depends — on tier, contract and configuration. Here is what really matters.
Consumer ChatGPT (free / Plus)
- No data processing agreement (DPA) by default
- Inputs can be used to improve the model
- Data processing not EU-resident
- No central control, no audit trail
- Garante: €15M fine against OpenAI (Dec 2024)
GDPR-compliant use requires
- Data processing agreement (DPA) in place
- Enterprise/API configured with EU data residency
- No training on company data
- Central governance, audit trail, PII filters
- Legal basis and transparency documented
The short answer
ChatGPT is not blanket “GDPR-compliant” or “non-compliant”. Three factors decide it: which tier is used, whether a data processing agreement exists and where data is processed.
What the supervisory authorities say
On 20 December 2024 the Italian data protection authority (Garante) issued a €15 million fine against OpenAI — among other reasons for a missing legal basis for training on personal data, transparency failures and an unreported data breach. OpenAI considers the fine disproportionate and is appealing. The case shows that generative AI is under close scrutiny by European regulators.
The tier decides
Free ChatGPT and ChatGPT Plus are generally unsuitable for processing personal company data — no DPA and potential use of inputs for model improvement. ChatGPT Enterprise and the API, by contrast, offer a DPA, optional EU data residency and a commitment not to train on customer data. Important: the API does not process EU-resident by default — EU residency must be actively configured.
The transfer problem
OpenAI is certified under the EU-US Data Privacy Framework (DPF) and offers standard contractual clauses. However, the DPF is legally contested and could be struck down — like its predecessors Safe Harbor and Privacy Shield. Anyone relying on it alone carries a residual transfer risk. EU-hosted models avoid the third-country transfer from the start.
The penalty dimension
Violations of the GDPR can be penalised with up to €20 million or 4% of global annual turnover — whichever is higher (Art. 83 GDPR). For most companies, however, the biggest risk is not the fine itself but uncontrolled data leakage via shadow AI.
How HOVIGuard helps
HOVIGuard provides centrally managed AI access — with EU-hosted models, configurable PII filters, audit trail and admin control. Instead of securing individual ChatGPT accounts, all teams get controlled access via a GDPR-oriented platform. Effectiveness additionally depends on the internal policy.

- EU data residency enabled
- Training on own data disabled
- Legal basis and transparency documented
- Technical filters for sensitive data (PII) in use
- Audit trail and access control established
Frequently asked questions: ChatGPT and the GDPR
Is the free version of ChatGPT GDPR-compliant?+
Generally not for processing personal company data. By default there is no data processing agreement, and inputs can be used to improve the model. For business purposes, Enterprise or API tiers with a DPA are preferable.
Is a data processing agreement (DPA) with OpenAI enough?+
A DPA is a necessary but not sufficient condition. You additionally need a legal basis, transparency towards data subjects, an assessment of the third-country transfer to the US and technical-organisational measures. The overall assessment is the responsibility of the company as controller.
What does the Italian fine mean for German and Austrian companies?+
The €15 million fine (December 2024) targeted OpenAI as the provider, not user companies. It does show, however, that supervisory authorities scrutinise generative AI closely. Companies should document and safeguard their own AI use both contractually and technically.
Is a US data transfer via the Data Privacy Framework safe?+
The EU-US Data Privacy Framework currently provides a legal basis for transfers to the US, but it is legally contested. Its predecessor agreements Safe Harbor and Privacy Shield were struck down by the CJEU. A residual transfer risk remains — EU-hosted models avoid the problem.
How does HOVIGuard make AI use more GDPR-oriented?+
HOVIGuard combines EU-hosted models, PII filters, audit trail and central admin control in one platform. This makes AI use steerable and traceable — without every employee using their own, unsecured accounts. Overall GDPR compliance additionally depends on the internal policy.
