Relating to the regulation of platforms for the sale and distribution of software applications for mobile devices; authorizing a civil penalty.

HB 4294 requires app stores (like Apple App Store or Google Play) operating in Texas to verify the age of users when they create an account. It mandates using reasonable methods to assign age categories - child (under 13), teenager (13-16), older teenager (17), adult (18-20), or legal adult (21+) - and obtain parental consent for minors. The law directly affects app stores and users under 18, with specific rules for handling minors' data and transactions. Violations could result in civil penalties authorized by the bill.
