Privacy Policy

Last updated: 9 September 2026

Finstack Health Coach helps you review health and fitness information, plan training and meals, and request personalized coaching. This policy describes the data used to provide those functions.

Data we process

• Google account identifier, email address, and display name for authentication.
• Health and fitness information you authorize through Google Health, including activity, workouts, sleep, heart and body measurements, nutrition, and hydration where available.
• Goals, preferences, check-ins, plan completion, meal information, notes, and coaching questions you enter.
• Meal photographs selected for nutrient estimation. The image is processed for the requested estimate and is not retained by Finstack Health Coach.

How data is used

Data is used only to provide your dashboard, history, plans, nutrition records, synchronization, safety checks, and coaching. Compact relevant context may be sent to OpenAI only when you request an AI-powered answer, plan, or meal estimate. AI requests are configured not to be stored by the model provider. We do not sell health data, use it for advertising, or use it to track you across apps or websites.

Storage and retention

Your account data is stored on Finstack-operated infrastructure and retained while your account remains active. You can export or permanently delete it from Settings → Account & privacy. Operational backups may persist for a limited recovery period before automatic expiry.

Your choices

You control Google permissions and may revoke them through your Google Account. You may correct user-entered meal estimates, export your data, or delete your account in the app.

Security and children

We use encrypted transport, access controls, encrypted provider tokens, and restricted server access. The service is not directed to children under 13.
