We understand that when you chat with Nia in the Hello Heart app, you will share details about your health, medications, and blood pressure readings. Nia only uses your data to make your experience more personalized and helpful, with relevant responses. Nia 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 Nia?
Access is limited to authorized Hello Heart personnel who use the minimum information necessary to perform their roles. Hello Heart monitors Nia'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 Hello Heart uses AI?
You can read Hello Heart's full AI-Assisted Feedback consent form here. It covers how the AI system works, your rights, and how to contact Hello Heart.
What sources does Nia rely on?
Responses from Nia are grounded in clinician-vetted medical knowledge focused on general wellness and heart health. For blood pressure and heart rate questions, Nia 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 Nia is unsure about a question, it will acknowledge it. However, Nia is not perfect, and not a replacement for professional medical care. When something feels serious, always seek a healthcare provider.
What if I think Nia's answer is wrong or unclear?
You can provide feedback regarding Nia 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 Hello Heart Support by emailing support@helloheart.com and be sure to include all details, and screenshots if possible.
