Overview

  • Governor Gavin Newsom signed the Opt Me Out Act requiring web browsers to offer a user setting that sends a universal opt-out preference signal to stop third-party data sales or sharing across sites.
  • The Opt Me Out Act becomes operative on January 1, 2027 and authorizes the California Privacy Protection Agency to issue implementing regulations.
  • The law includes a safe harbor shielding browser developers from liability when businesses fail to honor the opt-out signal.
  • Newsom also signed AB 656 mandating that social media platforms provide a clear way to cancel accounts and that cancellation triggers full deletion of the user’s personal data.
  • SB 361 strengthens the state’s Data Broker Registration Law by expanding disclosures about what information brokers collect and who can access it, building on the CCPA, CPRA/CPPA, and the DELETE Act’s statewide deletion portal due in August 2026.
