The bill requires an operating system provider to:

• Provide an accessible interface at account setup that requires an account holder to indicate the birth date or age of the user of that device to provide a signal regarding the user's age bracket (age signal) to applications available in a covered application store;
• Provide an application developer (developer) that requests an age signal, with respect to a particular user, the technical ability to call an age signal via a reasonably consistent real-time application programming interface that identifies, at a minimum, the user's age-bracket data; and
• Send only the minimum amount of information necessary to comply with the bill. An operating system provider shall not share an age signal with a third party for a purpose not required by the bill

A person that violates the bill must pay a civil penalty of not more than $2,500 for each minor affected by each negligent violation or not more than $7,500 for each minor affected by each intentional violation. The penalty is assessed and recovered in a civil action brought by the attorney general.

This is stupid. I doubt this bill will pass. But one of these days, sooner rather than later, laws like this will be passed in your jurisdiction. The only solution is to learn how to use tools that will help you evade such authoritarianism.
