1. What We Collect
Health Notes collects the minimum data necessary to provide its service:
- Account information: email address and name (via Google OAuth or email registration).
- Health data you enter: food logs, body metrics, supplement schedules, symptom records. This data is stored in your account and is only accessible by you (and family members you explicitly grant access to).
- AI usage metadata: we log the type of AI request (e.g. "food photo", "symptom text"), whether it succeeded, and how long it took. We do not store the content of your AI requests — your food descriptions, symptom details, and photos are processed and discarded.
2. How We Use Your Data
- To provide and improve the Health Notes service.
- To process your inputs via AI (text, voice, images) and return structured health data. AI processing is done via third-party providers (see section 4).
- To enforce usage limits and prevent abuse.
We do not sell, rent, or share your personal data with third parties for marketing purposes.
3. Data Storage & Security
Your data is stored in a Supabase-hosted PostgreSQL database with row-level security (RLS) enabled. Each user can only access their own data. All connections use TLS encryption.
The app supports offline usage via local storage (IndexedDB). Data cached locally on your device stays on your device until synced.
4. Third-Party Services
- Supabase — database hosting and authentication.
- AI providers (Anthropic Claude, Google Gemini, OpenAI) — process your text, voice, and image inputs to extract structured health data. Inputs are sent to these providers for processing and are subject to their respective privacy policies. We do not store the raw inputs after processing.
- Vercel — application hosting.
5. Your Rights
You can:
- Access all data stored in your account via the app.
- Delete individual entries at any time.
- Request full account deletion by contacting us.
6. Cookies
We use only essential cookies for authentication and locale/theme preferences. No tracking or advertising cookies are used.
