ConductAtlas Analysis

Why it matters (compliance & governance perspective)

This restriction limits one specific high-risk use of Customer Data, providing a defined protection against that data being used to improve external AI systems.

Interpretive note: The clause is silent on whether Klaviyo may use Customer Data to train its own (first-party) foundation models; that question is not addressed by this claim.

Consumer impact (what this means for users)

Customer Data is protected from being used as training input for third-party foundation models.
