California Opt Me Out Act (AB 566) Signed into Law

State of CaliforniaOctober 8, 2025California Attorney General

Summary

Governor Newsom signed the California Opt Me Out Act (AB 566), requiring browsers to offer built-in opt-out preference signals (OOPS) by January 2027. This makes California the first state to mandate that browsers provide easy-to-use tools for consumers to automatically communicate their privacy preferences to websites, closing a major gap in CCPA enforcement.

Remedy

Requires browsers operating in California to provide opt-out preference signals (OOPS) to allow users to automatically tell websites not to sell or share their personal information. Effective January 2027.

Contract Impact

In-house legal teams should review browser vendor agreements and technology procurement contracts to ensure that any browser-based products or services offered to California users include the mandated opt-out preference signals. Additionally, data processing agreements with websites and third parties must be updated to honor these signals when received, potentially requiring amendments to consent clauses, data sale provisions, and compliance obligations under the CCPA.
