This law prohibits companies running websites, services, or apps aimed at minors from advertising certain products like alcohol or firearms to young users. These companies also can't target minors based on personal information, like their location or profile, unless they take steps to avoid such targeting. The law defines minors as anyone under 18 living in California and specifies that operators mustn't knowingly use a minor’s data to market the restricted items. Furthermore, an advertising service informed that the content is directed at minors must avoid advertising those restricted products. However, if products appear in content not primarily intended for marketing, it's allowed. Restricted products include items like tobacco, cannabis, and certain dangerous materials.

This law requires websites and apps aimed at or known to be used by minors to allow those under 18 to remove content they have posted. They must clearly inform minors that they can delete their posts, how to do it, and that deletion may not mean complete removal from the internet. The law does not force operators to delete content if it's required by other laws to be kept, was posted by someone else, was anonymized, if the minor doesn’t follow deletion steps, or if the content was paid for. Operators comply if they make the content invisible to the public, even if it’s still on their servers, but not if others have copied it. They aren't required to collect users' ages.

This part of the law started being in effect on January 1, 2015.
