Clean Room Analyst+
The clean room enables privacy-safe audience matching between you and your partners. Advertisers can measure overlap with your segments without either party exposing raw user data.
How It Works
- You create a segment and set up a sharing protocol with Clean Room match type.
- The advertiser submits their IDs (e.g., RampIDs) via the protocol or Partner API.
- Nucleus computes the overlap internally.
- Only the overlap count and match rate are returned — never individual records.
No user-level data leaves the platform at any point.
Match Reports
Every clean room query generates a match report containing:
| Field | Description |
|---|---|
| Segment | Which segment was matched against |
| IDs Submitted | Number of IDs the partner provided |
| Overlap Count | How many IDs matched your segment |
| Match Rate | Percentage of submitted IDs that matched |
| Date | When the query was executed |
Reports are stored and accessible from the protocol detail view in the Sharing tab.
Access Methods
- UI — View and run matches from the Sharing tab protocol detail page.
- Partner API — Partners can submit match queries programmatically via the Partner API endpoint.
⚠️
Clean room queries are rate-limited to prevent enumeration attacks. Partners cannot reverse-engineer segment membership from repeated queries.
