PII discovery

Find where customer data lives in the warehouse.

Chameleon helps data and compliance teams maintain a registry of customer data by mapping BigQuery tables and columns, connecting policy context, and showing where deletion work needs to reach.


Why it matters

Warehouse visibility

Map warehouse tables and columns so teams can see where identifiers, contact fields, and derived customer records appear.

Registry context

Keep PII location, owner, deletion strategy, and policy status together instead of spreading privacy context across tickets and docs.

Audit readiness

Give compliance reviewers a concrete registry surface before a deletion request or privacy audit becomes urgent.


Chameleon workflow
01 / Connect

Start from BigQuery assets and dbt context that describe the tables and models in scope.

02 / Map

Build a registry of tables, columns, PII classifications, owners, and deletion strategies.

03 / Review

Surface policy status and fields that require registration, cleanup, or manual review.

04 / Prove

Use the registry as the source of truth when deletion work needs evidence across connected systems.
