CONSUMER HEALTH DATA PRIVACY POLICY

Effective Date: 4/29/2025 Last Updated: 4/29/25

Halozyme, Inc. and its subsidiaries and affiliates (collectively “Halozyme,” ”we,” “us,” and “our”) is committed to respecting your privacy.  This Consumer Health Data Privacy Policy supplements the Halozyme Privacy Policy and applies to personal data defined as “consumer health data” subject to the Washington State My Health My Data Act.

The consumer health data we collect depends on the context of your interaction with us. Examples of consumer health data we collect include information about an individual’s:

• health conditions, treatment, diseases, or diagnoses;
• use or purchase of medications;
• diagnoses or diagnostic testing, treatment, or medication;
• health-related surgeries or procedures;
• measurements of health information;
• symptoms of use or adverse events; and
• information that could identify an attempt to seek health care services or information.

We collect consumer health data from the following sources:

• Directly from you when you interact with us or our service providers or use our products, services, or programs;
• Indirectly from you when you visit our websites through use of cookies and other tracking technologies;
• From healthcare providers, pharmacies, insurers, and other funding partners; and
• From publicly available sources such as social media websites and literature monitoring.

We collect consumer health data in order to provide you with information about our therapies, provide you with our therapies, and facilitate your use of and payment for our therapies. We also use the consumer health data we collect to market our products, services, and programs to you, compile statistics, conduct research, improve our products, services, and programs, and comply with legal and regulatory obligations such as adverse event reporting required by the Food and Drug Administration (FDA).

We disclose consumer health data to our service providers and business partners so that they may help us provide our products, services and programs, and other business functions. With your authorization, we may also disclose consumer health data to healthcare providers, pharmacies, patient assistance program partners, insurers, and other potential funding sources. We also disclose consumer health data to regulatory bodies as required by law.

We may also disclose consumer health data to the parties of a corporate transaction such as a merger or acquisition. We may also disclose consumer health data to government agencies or otherwise as necessary to prevent, detect, or investigate fraud or threats to health, safety, or legal rights.

Washington residents have the following rights with respect to their consumer health data, subject to certain exceptions:

• The right to confirm whether we process your consumer health data, and to access and receive a copy of your consumer health data;
• The right to a list of all third parties and affiliates with whom we have shared or sold your consumer health data and an email address or other online mechanism that you can use to contact each third party;
• The right to delete your consumer health data;
• The right to withdraw consent to the collection, sharing, or selling of consumer health data.

You can submit a request to exercise these rights using any of the mechanisms listed in the Contact Information section below.  Depending on the type of request, we may need to verify your request before we can fulfill it. Please note that certain exceptions may apply to these rights (e.g., we may be unable to honor a request to delete if it conflicts with our legal obligation to retain and report adverse event data). Finally, please review the Halozyme Privacy Policy for additional rights you may have with respect to your personal data more generally.

You also have the right to appeal any decisions we make with regard to your rights request. If your appeal is unsuccessful, you can raise a concern or lodge a complaint with the Washington State Attorney General at www.atg.wa.gov/file-complaint.

We may revise this policy from time to time. When we make changes to this policy, we will post the updated version on our websites and indicate the date the policy was last updated. We encourage you to review this policy periodically to check for any updates. Your continued use of our websites or services indicates your consent to the terms of this policy.
