Privacy Policy

Last updated: October 11, 2026

Your privacy matters. This policy explains what data we collect, how we use it, and your rights. We believe in transparency — no surprises.

Next Arc Studio ("we", "us", or "our") operates the HeartWise mobile application (the "App"). This Privacy Policy explains how we collect, use, and protect your information.

1. Information We Collect

  • Account information (email, display name)
  • Meal logs and food entries
  • Cholesterol readings (if entered by you)
  • Meal photos (stored securely in cloud storage)
  • App usage preferences and settings
  • App usage events (which screens and features you use), never your readings, foods or notes

All data you provide is entered voluntarily. We do not collect data from your device's health apps or sensors unless you explicitly enter it.

2. How We Use Your Information

  • Provide core app functionality (meal tracking, scoring, insights)
  • Sync your data across your devices
  • Generate personalized dietary insights and recommendations
  • Process AI-powered meal photo analysis
  • Manage your account and subscription
  • Understand which features are used so we can improve the App

3. Data Storage and Sync

Your data is synced to secure cloud servers so you can access it across devices. Meal photos are uploaded for AI analysis and associated with your account.

4. Third-Party Services

Convex — Backend database and real-time sync
Clerk — Authentication and account management
RevenueCat — Subscription and purchase management
Cloudflare R2 — Secure photo storage
OpenRouter — AI-powered meal analysis (meal photos are sent for analysis)
PostHog — Product analytics: which screens and features are used, linked to your account ID. No health readings, foods, notes, IP addresses or location, and nothing used for advertising

5. Data Sharing and Sale

🛡️We do not sell, rent, or trade your personal data.

We share data only with the services listed above, solely for operating the App.

6. Data Retention and Deletion

Your data is retained while your account is active. Delete your account via Settings > Account > Delete Account. All data is permanently removed.

7. Withdrawing Your Consent

AI meal analysis is optional and off until you allow it. You can turn it on or off at any time in Settings > Preferences > AI Data Sharing. While it is off, nothing is sent to our AI provider, and barcode scanning, food search and manual logging continue to work.

Apple Health access can be withdrawn in the iOS Health app > Sharing > Apps, and camera, photo and notification permissions in iOS Settings > Heartwise. To withdraw consent for all processing, delete your account as described above.

8. Security

We use industry-standard security: HTTPS/TLS, secure authentication, and access controls.

9. Children's Privacy

The App is not intended for children under 13. We do not knowingly collect data from children.

10. Health Disclaimer

⚕️HeartWise is a wellness tracker, not a medical device.

It does not diagnose, treat, cure, or prevent any disease. Scores and insights are informational only. Consult a healthcare provider.

11. Changes to This Policy

We may update this policy. The "Last updated" date will be revised accordingly.
