GDPR-compliant AI hosting

GDPR doesn't ban AI — it requires you to know what personal data goes where, on what legal basis, and who can reach it. For AI that reduces to one sentence: a prompt is data processing. If client, employee or patient data is in it, every transfer rule applies. Here are the five things to require from any AI host — and what we put in the contract.

The five requirements

1. EU residency AND an EU operator

An EU datacenter run by a US-owned provider remains within US jurisdiction (CLOUD Act, 2018) — US authorities can compel US companies to produce data wherever it is stored. Require both: EU infrastructure and an EU-owned operator, with no US processor in the path.

2. A DPA that covers the whole trail

Not just the chat: prompts, logs, embeddings, backups. Where does each live, who can access it, how is access logged?

3. No training on your data — in writing

Open-weight models served privately train on nothing. Whatever the vendor, get the no-training commitment into the contract, not the FAQ.

4. Provable deletion and export

Retention you control, deletion you can demonstrate, and a documented export path if you leave.

5. An SLA with something behind it

A written availability number with defined RTO/RPO — and infrastructure (redundancy, backups, monitoring) that makes it credible.

And one honest sentence: GDPR compliance is a process, not a product. Private AI hosting solves the technical side — data stays with you, logged, in the EU, with no US processor — but legal bases, notices and internal policies remain your (and your lawyer's) work. Anyone selling "GDPR compliance" in a box should be asked what exactly they mean.

Practical guidance, not legal advice.
