This bill aims to enhance the protection of minors in Washington state when using online services, products, or features. It introduces a new chapter to Title 19 RCW, establishing definitions for terms such as "addictive feed," "addictive internet-based service or application," and "dark pattern." The bill mandates that businesses providing online services likely to be accessed by minors must implement age estimation practices, apply privacy protections, and configure default privacy settings to prioritize minors' safety. Additionally, it prohibits the collection, sale, or retention of personal information from minors under 13, unless necessary for age assurance compliance.

Furthermore, the bill outlines specific actions that businesses must take to protect minors, including providing clear privacy information, enforcing community standards, and ensuring that minors are aware when they are being monitored. It also restricts the use of personal information in ways that could harm minors and prohibits the use of "dark patterns" to manipulate minors into providing personal information. The legislation establishes penalties for violations and emphasizes that compliance does not shield businesses from liability for harm caused to minors. Overall, the bill seeks to create a safer online environment for children by regulating how online services interact with and protect young users.
