Data Clean Room
A secure environment where two or more parties can match and analyse their combined first-party data without either party seeing the other's raw, underlying data.
Definition
A secure environment where two or more parties can match and analyse their combined first-party data without either party seeing the other's raw, underlying data.
Why it matters
Data clean rooms are the primary mechanism for cross-channel measurement and audience matching in a world where raw data sharing is increasingly restricted by privacy regulation and platform policy.
Key consideration
A clean room means neither side sees raw data — only matched, aggregated output. Do not go into a clean room partnership expecting log-level access for independent analysis; that defeats the purpose of the clean room itself.
