keeper of secrets

Holds private knowledge

A keeper of secrets is someone entrusted with confidential information—the friend who knows what you haven't told others, the advisor privy to sensitive matters.

The phrase emphasizes both the holding and the protecting: She's always been my keeper of secrets.

It can describe official roles (a confessor, a security-cleared official) or intimate ones (a confidant, a therapist).

Sometimes used playfully or ominously depending on context.
