## Summary
Data clean rooms are managed compute environments where two parties can run queries against their combined datasets without exposing raw records, used for cross-platform measurement, audience building, and campaign optimization.

## Definition
Data clean rooms are privacy-preserving environments that let two or more parties (typically a publisher and an advertiser, or two platforms) run approved queries against their combined data without either side seeing the other's raw records. They emerged as third-party cookies deprecated and privacy regulation tightened; they let advertisers measure campaigns and build audiences against shared identifiers without moving personal data between systems.
