4. AI Processing
NeuroHeart AI may utilize third-party artificial intelligence service providers to generate conversational responses and wellness guidance. These providers currently include, but are not limited to:

Information submitted to AI providers is transmitted solely for generating requested responses.
Where available, NeuroHeart AI enables provider privacy controls intended to prevent customer content from being used to train AI models.
NeuroHeart AI does not intentionally provide HRV history, heart rate history, HealthKit records, Apple Watch wellness data, calendar data, or long-term wellness records to AI providers unless required to deliver a feature specifically requested by the user.
