SB 166 Wisconsin Senate · 2025-2026 Regular Session

Relating to: consumer data protection and providing a penalty. (FE)

SB 166 creates a new legal framework for consumer data protection by defining key terms like "personal data," "consent," "biometric data," and "dark patterns" in Wisconsin law. It directly affects businesses that collect personal data from Wisconsin residents (defined as individuals acting in personal, not commercial, contexts) by establishing standards for how they must handle such data. The bill’s key mechanism is setting clear definitions - such as requiring explicit consent for data processing, banning "dark patterns" that trick users, and excluding deidentified data or public records from coverage - to enable future enforcement. It does not yet impose new restrictions or penalties but provides the foundational definitions needed for implementing data protection rules.
