require age verification before an individual may access an application from an online application store, publicly available website, electronic service, or other online platform.

HB 1237 requires app stores and developers to verify the age of users before they can access applications, with specific rules for children under 16. App stores must determine age, obtain parental consent for minors, provide digital age signals (e.g., 13-15 or 16-17), and enable parental controls for time limits and activity monitoring. The law directly affects app stores (manufacturers), app developers, and users under 16, applying to platforms distributing apps like mobile app stores. Violations could result in $5,000 civil penalties per affected child, enforced by state attorneys general.
