Senate Bill No. 503, known as the "Minor Exploitation Prevention Act," aims to enhance protections for minors in the context of mobile application distribution. The bill establishes a framework that requires application distribution providers to implement age assurance measures, such as requiring users to declare their age, using reasonable methods to determine age categories, and allowing users to correct their age information. Additionally, it mandates that developers of covered applications disclose whether their apps provide different experiences for minors and restrict minors from accessing adult-only content. The bill also outlines the responsibilities of application distribution providers and developers, including the prohibition of personalized advertising to minors and the requirement for parental controls.

The legislation provides liability protections for application distribution providers acting in good faith, shielding them from responsibility for inaccurate age signals or developer conduct, while also allowing them to use various methods to determine user age. Developers are held accountable for correctly identifying their applications and are not liable for erroneous age signals if they make reasonable efforts to comply with age assurance measures. Enforcement of the act is designated to the attorney general, who can impose civil penalties for violations, while a private right of action is explicitly prohibited. The act is set to take effect on August 1, 2028.
