When a recruiting team evaluates an AI interview notetaker in Europe, the feature lists look almost identical. Every serious tool records the interview, transcribes it, and turns an hour of conversation into structured notes and action items. The axis that actually separates them is quieter and harder to see on a pricing page: where your candidates' recordings physically live. This guide explains the difference between EU, UK, and US hosting, why it matters for interview data specifically, and how to confirm the answer for any tool.
The short version: EU, UK, and US hosting can all be lawful. Only one of them keeps the data inside the EU. For a growing number of European buyers, especially in Germany, Austria, and Switzerland, that physical location is the point that decides the purchase.
Why data residency matters more for interviews than for most tools
Interview recordings are unusually sensitive. They contain a candidate's voice, their answers, and often personal circumstances shared in conversation, tied to a named individual who is not yet an employee and has limited leverage. That combination puts interview audio near the top of what security reviews and works councils scrutinize.
So the trigger for a residency conversation is rarely a feature gap. It is a line in a security review, a customer contract, or a DACH works council agreement that says candidate data must stay in the EU. When the audio and its transcript sit on infrastructure outside the EU, some organizations cannot sign off, regardless of how good the product is or how many certifications it holds.
There is a practical dimension too. When a candidate asks where their recording is stored, or a works council reviews a new tool, a clear answer of "inside the EU" is easier to defend than an explanation of adequacy decisions and contractual clauses. The legal basis may be sound either way, but the conversation is shorter when the data never leaves the region.
EU vs UK vs US hosting: what actually differs
Three hosting regions come up repeatedly when European recruiting teams shortlist interview notetakers. Here is what each one means in practice.
UK hosting (adequacy)
Since Brexit, the UK is a third country under the GDPR. EU data can still flow there because the EU granted the UK an adequacy decision, backed by standard safeguards. This is a legitimate legal basis. Metaview, a well-built interview-intelligence product, publicly documents hosting all data on AWS in the United Kingdom. For an EU recruiting team, that means candidate recordings leave the EU and rest in the UK under adequacy. It is compliant, and it is UK residency, not EU in-region residency.
US hosting (SCCs or the Data Privacy Framework)
US-hosted tools rely on standard contractual clauses or the EU-US Data Privacy Framework to move EU data across the Atlantic. BrightHire, for example, documents hosting on Google Cloud in the US. This too can be lawful, but it sits one step further from EU residency than UK hosting does, and the transfer basis for US data has been challenged in court before. If US hosting under SCCs is acceptable to your organization, it is a valid choice. If your requirement is that interview data stays in the EU, it will not meet that bar.
EU in-region hosting (residency)
An EU-hosted tool keeps interview audio and transcripts on infrastructure physically inside the EU, so there is no cross-border transfer to reason about at all. Numi is built on that basis: it records, transcribes, and summarizes interviews and extracts action items and decisions, all processed on European infrastructure in Frankfurt, and it does not train on your data. Residency is a yes-or-no property, not a spectrum, which is what makes it useful as a filter.
Adequacy is a legal mechanism: the EU decides a country's data-protection regime is strong enough that EU data can lawfully rest there. In-region residency is a physical fact: the data never leaves the EU. A UK-hosted tool relies on adequacy; an EU-hosted tool gives you residency. Both can be compliant. Only residency answers the question of where the recording physically sits.
How to confirm where a notetaker stores your interview data
Do not infer the hosting region from marketing copy. Run any shortlisted tool through a short, concrete checklist and get the answers in writing.
- Confirm the hosting region in the DPA. Ask where interview audio and transcripts are physically stored, and get the answer in the data processing agreement or a security document, not a sales email.
- Read the current sub-processor list. The primary host is only part of the picture. AI transcription and summarization often run through additional sub-processors that may sit in another region even when the main database does not. Verify where each one operates.
- Test the consent and deletion flow. Recording an interview creates obligations. Record a mock interview, then delete it, and confirm what actually disappears and how fast. See our guide on recording job interviews in Germany and the EU for the consent side.
- Validate the ATS integration you depend on. Notes are only useful if they reach your workflow. Push a summary into your ATS, and check both that the round trip works and that the destination's hosting matches your policy.
- Check the no-training commitment. Confirm the exact wording that the vendor does not train models on your data, and that the restriction extends to sub-processors.
Residency is not the only question: the EU AI Act
Keeping interview data in the EU handles the residency question. It does not, on its own, handle the EU AI Act. Using AI in recruitment is treated as a high-risk use case, and that classification attaches to what the tool does, not only where it is hosted. A notetaker that simply records, transcribes, and summarizes is far lighter-touch than one that scores, ranks, or filters candidates automatically. If you are weighing that distinction, read our explainer on why recruiting interview notetakers can be high-risk under the EU AI Act.
The clean position for most teams is to keep a human making the decision: use the tool to capture the record and the transcript, and let your panel reach the outcome. That keeps the residency answer and the AI Act answer simple at the same time.
Making the decision
Start by writing down your one non-negotiable. For most European recruiting teams asking this question, it is: interview data must stay in the EU. If that is true for you, residency filters the market quickly, because it is a physical yes-or-no. If UK or US hosting under transfer mechanisms is acceptable to you, the field is wider and mature US- and UK-hosted tools are credible choices.
Everything else, the summaries, the action items, the notes your recruiters read, is broadly comparable across the serious options. That is exactly why residency, rather than features, tends to be the part that actually decides the purchase. It is also the part only you can decide.
