We understand that when you chat with Joy in the Happy Hearts app, you will share details about your health, medications, and blood pressure readings. Joy only uses your data to make your experience more personalized and helpful, with relevant responses. Joy does not use it for clinical diagnoses or medical decisions. Below are a few answers about how we protect your conversations.
Who can see my conversations with Joy?
Access is limited to authorized Happy Hearts personnel who use the minimum information necessary to perform their roles. Happy Hearts monitors Joy's quality through an evaluation framework using blinded data that does not use or expose personal information, while checking for clinical accuracy, completeness, tone, and guardrail adherence.
Where can I read more about how Happy Hearts uses AI?
You can read Happy Hearts' full AI-Assisted Feedback consent form. It covers how the AI system works, your rights, and how to contact Happy Hearts.
What sources does Joy rely on?
Responses from Joy are grounded in clinician-vetted medical knowledge focused on general wellness and heart health. For blood pressure and heart rate questions, Joy uses your real health data from the app plus approved heart health knowledge. It's designed to give reliable, evidence-based guidance, not unverified claims. If Joy is unsure about a question, it will acknowledge it. However, Joy is not perfect, and not a replacement for professional medical care. When something feels serious, always seek a healthcare provider.
What if I think Joy's answer is wrong or unclear?
You can provide feedback regarding Joy by rating the response in the chat. If you have a health concern that needs clarity, we recommend speaking with your doctor, health care physician, or pharmacist. If the issue is a persistent error in responses, please reach out to Happy Hearts Support by emailing support@happyhearts.com and be sure to include all details, and screenshots if possible.
