Deya Consumer Health Data Privacy Policy

This Consumer Health Data Privacy Policy explains how Deya Health, Inc. (“Deya,” “we,” “us,” or “our”) collects, uses, shares, and protects consumer health data—as defined under applicable U.S. state laws—when you use the Deya mobile application (the “App”). It also outlines your rights and choices regarding this data. This policy supplements our general Deya App Privacy Policy.

1. What Consumer Health Data We Collect

When you use the App to support your eye health and overall wellness, we may collect the following types of consumer health data:

• Individual health conditions, treatment, diseases, or diagnosis. We collect self-reported information about your wellbeing through in-app quizzes or questionnaires. This may include data related to your eye health, including medical conditions, medical and eye history, lifestyle, medications (dosage, timing, frequency), eye images, and other information relevant to your care. Although we do not diagnose medical conditions, this information may reflect aspects of your health or perceived wellbeing and may be considered indicative of a health condition.
• Social, psychological, behavioral, and medical interventions. Based on your responses and how you interact with the App, we may collect information about behavioral or medical routines related to your eye care—such as the use of prescribed eye drops or medications, tracking screen time, logging time spent outdoors, or documenting adherence to glasses or contact lens use. These features are intended to support your ongoing eye health and wellness and to help facilitate communication with your healthcare provider. They are not intended to treat or cure medical condition.
• Health-related surgeries or procedures. If you choose to voluntarily share information about past or planned medical procedures or surgeries, that information may be collected and stored as part of your account data.
• Bodily functions, vital signs, symptoms, or measurements of the information. You may choose to provide information about your physical state—such as eye symptoms (e.g., eye pain, poor vision, itchiness, discomfort, or headaches)—through your responses in the App. 
• Any inferences of the above categories of health data derived or extrapolated from non-health information. We may draw limited inferences about your wellbeing based on how you interact with the App—for example, how often you log in or complete symptoms check-ins. While this information is not health data on its own, it may suggest wellness needs. These inferences are used only to personalize your in-app experience and are not used or shared for advertising or promotional purposes.

2. How We Collect Consumer Health Data

We collect consumer health data directly from you:

• When you fill out questionnaires or assessments.
• When you upload eye images, videos or symptom information.
• When you interact with the App features, such as wellness tools or reports.
• When you communicate with your eye doctor through the App

We may also generate inferences from your App usage—for example, if you use a certain feature frequently, we may suggest similar content.

3. Why We Use Consumer Health Data

We collect and use your consumer health data as necessary to provide you with the services you request through the App—specifically, to support your wellness, generate personalized insights, enable secure communication of your health information with your designated eye care provider and support virtual consultations. This includes:

• Helping you manage your care. We use your data to deliver personalized summaries, reminders, and wellness tips based on the information you provide and provide relevant in-app content or alerts (e.g., weather-related eye health advisories).
• Sharing data with your doctor. With your consent, we make your submitted information (like images and symptom updates) available to your designated eye care provider and their staff (such as technicians or assistants) for review during virtual or follow-up visits, to support your care.
• Improving the App. We analyze anonymized or aggregated data to understand what features are most helpful and improve App design, content, and functionality.
• LLM-based insights. We may use de-identified data with large language models (LLMs) to generate helpful summaries, wellness recommendations, or user insights. These tools never receive identifiable health data.
• Legal compliance and safety. We use data to meet legal obligations, protect the App and its users, and detect unauthorized or harmful activity.
• With your consent. If you choose to share your data for a different purpose, we will explain how it will be used at that time.

4. When We Disclose Consumer Health Data

We may disclose your consumer health data in the following cases:

• With service providers that help us operate the App (e.g., hosting, analytics, secure storage). 
• With your doctor, if you choose to share your information with them.
• With legal or regulatory authorities when required to comply with the law or protect rights, safety, or integrity.
• In a business transfer, such as a merger, acquisition, or sale of assets.
• With others, but only if you direct us to or provide your explicit consent.

We do not sell your consumer health data.

5. Your Rights and How to Exercise Them

Depending on where you live, you may have the right to:

• Confirm whether we are collecting, sharing, or selling your consumer health data, and access your consumer health data.
• Delete your consumer health data.
• Withdraw your consent from our collection or sharing of your consumer health data.
