What it does

Regulated entities must publish a consumer health data privacy policy linked from their homepage and get opt-in consent to collect or share consumer health data. Selling it requires a signed authorization. Consumers get rights to access, delete and withdraw consent. Geofencing within 2,000 feet of health care facilities is banned. 'Consumer health data' is defined broadly and includes inferences from non-health data.

Who it applies to
Any legal entity that conducts business in Washington or targets Washington consumers and determines the purpose and means of processing consumer health data, with no revenue threshold. Small businesses (health data of fewer than 100,000 consumers a year, or under 50% of revenue from health data and fewer than 25,000 consumers) got a later compliance date.
Penalties
A violation is a per se violation of the Washington Consumer Protection Act: AG civil penalties up to $7,500 per violation (RCW 19.86.140). Private right of action for actual damages, with possible treble damages and attorney fees.
