Protecting personal data privacy.

HB 1671 establishes new data privacy rules for Washington residents, requiring businesses to obtain clear "affirmative consent" before collecting or processing personal data. It specifically protects sensitive consumer health data - including gender-affirming care, reproductive health, and biometric information - and bans "dark patterns" designed to trick users into sharing data. Businesses must provide easy-to-understand disclosures about data use, allow consumers to revoke consent easily, and avoid inferring consent from user inaction. The law directly affects Washington consumers and companies handling their personal data, with exemptions for research approved by ethics boards.
