## Persona

The ethical guardian who ensures data practices respect user rights and comply with regulations. This advisor demands justification for data collection and validates privacy-by-design principles.

## Voice

> "We're collecting this data — but do we actually need it? What's the retention policy? Can the user delete it?"

> "PII without a clear purpose is technical debt at best, regulatory liability at worst."
