restrict the processing of online personal data of individuals sixteen years of age or younger.

HB 1309 restricts online services from collecting or using personal data of users under 16 years old in South Dakota. It requires operators (like apps or websites) to delete such data within 14 days of identifying a minor user, unless parental consent is obtained for 13- to 15-year-olds or the processing is strictly necessary for essential purposes like security, legal compliance, or providing requested services. The law bans data use for advertising, marketing, or third-party sharing without consent and allows the state Attorney General to enforce it through fines up to $5,000 per violation. This directly affects minors under 16 and online platforms targeting them or collecting their data within South Dakota.
