1. Who We Are

MetabolicOS ("the App", "we", "us") is a personal health tracking application that runs entirely in your browser. The App is provided as a demonstration and personal-use tool. We are not a healthcare provider, insurance company, or HIPAA-covered entity.

2. Data We Collect — and Don't

Data stored on your device only: All health information you enter — weight, blood pressure, food logs, medications, workouts, and any other personal data — is stored exclusively in your browser's localStorage. It never leaves your device and is never transmitted to our servers (we have no servers).

The only external data transmission: When you use the Barcode Scanner feature, the app sends a barcode number (a string of digits with no personal information attached) to Open Food Facts (openfoodfacts.org), a free public food database. No personal data, health data, or identifying information is included in this request. Open Food Facts is a nonprofit with its own privacy policy at openfoodfacts.org/privacy.

We do not collect: names, email addresses, device identifiers, IP addresses, location data, usage analytics, crash reports, or any other telemetry. Zero.

3. No Advertising. Ever.

MetabolicOS contains no advertising and we have no advertising relationships. We do not share, sell, rent, or trade your data with any third parties for marketing purposes. Unlike many free health apps, your health data is not the product.

4. Your Data Export and Deletion

You own your data entirely. You can export a complete copy at any time from the Profile screen. To delete all your data, use the "Clear All Data" option in settings, or clear your browser's site data. Because data lives only on your device, we cannot restore deleted data — export regularly as a backup.

5. Data Security

Your health data is stored in browser localStorage, which is accessible only to this app on this device. We recommend:

• Enabling the in-app PIN lock (Profile → Security) to protect data on shared devices
• Not using MetabolicOS on shared or public computers
• Exporting and securing your backup file as you would any sensitive document

Because we have no server infrastructure, there is no central database that can be breached. Your risk exposure is limited to physical access to your device.

6. Children's Privacy

MetabolicOS is intended for users 13 years of age and older. We do not knowingly collect information from children under 13. If you are a parent and believe your child has used this app, you can clear their data by clearing the browser's site data for this app.

7. GDPR / CCPA / State Privacy Rights

Because we collect no personal data on our servers, most regulatory data subject rights (access, correction, deletion, portability) are fulfilled directly through the app's built-in export and clear functions. If you have a privacy-related question, contact us at the address in Section 10.

8. Changes to This Policy

If we ever change how data is handled — for example, by adding optional cloud sync — we will update this policy and notify users prominently before any change takes effect. We will never retroactively change data practices without consent.

9. Disclaimer — Not a Medical Device

10. Contact

For privacy questions or requests: use the feedback option in the app or contact the developer directly. We will respond within 30 days.

Last updated: April 2025 · By using MetabolicOS you agree to these terms.

1. Acceptance of Terms

By downloading, installing, or using MetabolicOS ("the App"), you agree to be bound by these Terms of Service. If you do not agree, do not use the App. These terms apply to the free demo version and any future paid versions of the App.

2. What MetabolicOS Is and Is Not

MetabolicOS is a personal data logging and tracking tool designed to help you record and visualize health-related information that you choose to enter. MetabolicOS:

• Is: a personal diary and visualization tool for health metrics you enter yourself
• Is not: a medical device, clinical tool, diagnostic platform, or medical records system
• Is not: monitored by any medical professional
• Does not: provide medical advice, clinical recommendations, or treatment protocols
• Does not: replace your doctor, pharmacist, dietitian, or any healthcare provider

3. No Medical Advice

Nothing in MetabolicOS — including AI-generated food parsing, nutrition targets, prediction models, health scores, goal recommendations, or any other feature — constitutes medical advice. The information presented is based solely on data you enter and generic algorithms, not clinical assessment of your individual health situation.

You should not make decisions about medications, supplements, diet, exercise, or medical treatment based solely on information displayed in MetabolicOS without consulting a qualified healthcare professional.

4. User Responsibilities

You are responsible for:

• The accuracy of data you enter into the App
• Keeping your device and PIN secure to protect your health data
• Regularly exporting backups of your data
• Consulting healthcare professionals for medical decisions
• Not using the App in a medical emergency

5. Predictions and AI Features

MetabolicOS includes predictive features (weight forecasts, trend analysis) and AI-assisted logging (natural language food parsing). These features use mathematical models applied to data you enter. They are illustrative tools only — not clinical predictions. Actual health outcomes depend on many factors outside the scope of any tracking app.

6. Pro Features

MetabolicOS offers a free tier and a Pro tier. The current demo activates Pro features at no charge for evaluation purposes. Future pricing is subject to change with reasonable notice. Subscription terms, if applicable, will be disclosed clearly at the time of purchase.

7. Disclaimer of Warranties

THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT. We do not warrant that the App will be uninterrupted, error-free, or that any information displayed is accurate or complete.

8. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE DEVELOPER SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING LOSS OF DATA, PERSONAL INJURY, OR HEALTH OUTCOMES, ARISING FROM YOUR USE OF OR INABILITY TO USE THE APP, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

Our total liability for any claim arising from use of the App shall not exceed the amount you paid for the App in the twelve months preceding the claim (or $0 for free users).

9. Health Emergencies

If you are experiencing a medical emergency, call 911 (US) or your local emergency number immediately. Do not rely on MetabolicOS or any app in an emergency situation.

10. Intellectual Property

The App, its design, code, and content are the intellectual property of the developer. You may use the App for personal, non-commercial purposes. You may not reverse-engineer, redistribute, or sell the App or its code without written permission.

11. Governing Law

These terms are governed by the laws of the State of Florida, United States, without regard to conflict of law principles. Any disputes shall be resolved through binding arbitration in accordance with the American Arbitration Association's Consumer Arbitration Rules, except that either party may seek injunctive relief in court for intellectual property violations.

12. Changes to Terms

We may update these Terms at any time. Material changes will be communicated through the App. Continued use after changes constitutes acceptance of the revised Terms.
