Maryland Age-Appropriate Design Code Act (Maryland Kids Code)

The Maryland Kids Code requires large online businesses whose products children under 18 are reasonably likely to use to design those products in children's best interests. Covered entities must complete data protection impact assessments, set high-privacy defaults for children, and avoid default profiling, default precise geolocation tracking, unnecessary data collection, and dark patterns. NetChoice's First Amendment challenge (NetChoice v. Brown, D. Md. No. 1:25-cv-00322) survived a motion to dismiss in November 2025 and is in discovery; the law has not been enjoined.
