Privacy Policy

Last updated: April 18, 2026

HeyHeart ("we", "us") is a heart-health-focused food tracker. This policy explains what we collect, how we use it, and the choices you have.

Information we collect

  • Account info: email address, name, and sign-in tokens via magic link.
  • Health & food data you provide: meal photos and descriptions, food items, portion sizes, baseline lab values (total cholesterol, LDL, HDL, triglycerides) that you optionally enter.
  • Derived metrics: saturated fat, fiber, sodium, inflammation score, plant diversity count, ultra-processed percentage, and LDL trend estimates we calculate from your logs.
  • Device & usage: device type, OS, app version, crash reports, and anonymized usage events used to improve reliability.

How we use it

  • To operate the app: analyze your meals, calculate heart-health metrics, and show your trends.
  • To authenticate you via magic-link email.
  • To send meal photos to third-party AI providers (e.g. Anthropic, OpenAI) strictly for nutritional identification. These providers do not train models on your data.
  • To monitor errors (Sentry) and improve the product.

How we store it

Data is stored on Supabase (PostgreSQL) with row-level security so only you can read your records. Meal photos are stored in Supabase Storage. All traffic is encrypted in transit (TLS) and at rest.

We do NOT

  • Sell your personal data.
  • Share your health data with advertisers.
  • Use your data to train third-party AI models.

Your rights

  • Access & export: email support@heyval.app to request a copy of your data.
  • Deletion: you can permanently delete your account and all associated data from the Settings screen inside the app. Deletions are irreversible and complete within 30 days across all backups.
  • GDPR / CCPA: if you reside in the EU/UK or California, you have additional rights (rectification, portability, opt-out of sale). We honor all of these — contact us to exercise them.

Children

HeyHeart is not intended for children under 13 and we do not knowingly collect data from them.

Medical disclaimer

HeyHeart is a wellness and educational tool, not a medical device. It does not diagnose, treat, or prevent any disease. Scores, estimates, and insights are based on general nutrition research and are not a substitute for professional medical advice.
