For Washington and Nevada Consumers Only

This notice supplements Zenas Privacy Policy and applies to personal information defined as “Consumer Health Data” subject to the Washington State My Health My Data Act (“MHMDA”) and the Nevada State Consumer Health Privacy Law (“Nevada Act”).

This “Consumer Health Data Privacy Policy” describes how Zenas collects, uses and otherwise processes Consumer Health Data in connection with this website and any of our other websites, mobile applications, or online services that link to this Privacy Policy (collectively referred to as the “Sites”). 

Consumer Health Data We Collect

Consumer Health Data means personal information that is linked or reasonably linkable to you and that identifies your past, present, or future physical or mental health status.

We may collect your Consumer Health Data depending on the context of your interactions with us and the choices you make (including your privacy settings), the products and features you use and applicable law. Because applicable laws define Consumer Health Data broadly, many of the categories of data we collect may, in some instances, be considered Consumer Health Data.

Consumer Health Data may include:

  • Information about your health-related conditions, symptoms, status, diagnoses, testing, or treatments (including procedures, medications, or other interventions). For example, we may collect such information through surveys or other communications with you for research studies.
  • Information that could identify your attempt to seek health-related services or information.
  • Other information that may be used to infer or derive data related to the above or other health information.

Sources of Consumer Health Data 

We may collect Consumer Health Data directly from you, from your interactions with our products and services, from third parties, and from publicly available sources.
