How does Claude protect my data privacy and safety?

Your health information is personal. That's why we've built Claude to work with integrations like Function with privacy and user empowerment at the core.

Connected only with your consent

Claude connects to Function only when you explicitly choose to enable the integration. Anthropic's Consumer Health Data Privacy Policy describes exactly how we collect, use, and protect your information—so you always know what to expect. We also protect sensitive health data from inadvertent sharing to other integrated connectors by requiring you to consent to each integration in conversations where Function data is being discussed.

Minimal data, maximum relevance

When you ask a health-related question, Claude pulls only the data it needs to answer that specific question. Your full health record isn't accessed unless it's relevant to what you're asking.

Your conversations stay private

Chats that use the Function integration are not used to train our models. We've designed our memory feature so that Claude does not use sensitive health data in future conversations, while still keeping in mind your areas of concern to inform your conversations.

Empowering you, not replacing your doctor

Claude is designed to help you better understand and take ownership of your healthcare journey — not to provide medical advice, diagnoses, or treatment recommendations. Always consult your physician for medical decisions.
