Communications: internet; age-appropriate design code act; create. Creates new act.

HB 5357, the "Age-Appropriate Design Code Act," requires businesses meeting specific thresholds (e.g., $25 million+ annual revenue or handling data of 50,000+ consumers) to design online services, products, or features accessed by known minors (under 18) with privacy and safety as defaults. It prohibits "dark patterns" that manipulate user choices, bans collecting precise geolocation data without consent, and mandates age-appropriate settings for minors. The law applies to businesses operating in Michigan that process personal information of minors, creating civil penalties for violations. It establishes a fund to support enforcement and defines key terms like "known minor" and "business" to clarify compliance requirements.
