Terms of Service

Effective date: September 1, 2025

Last updated: September 20, 2025

1. Acceptance of Terms

By downloading, installing, or using the VitalOS mobile application ("Service"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree to these Terms, do not use the Service.

2. Description of Service

VitalOS provides a privacy-first nutrition tracking application that:

• Stores all your personal health data locally on your device only
• Tracks nutritional information and dietary goals
• Provides AI-powered food recognition (3 free analyses per month, then Pro required)
• Syncs a community food database to your device (no personal data syncing)
• Operates without user accounts or email collection

3. How VitalOS Works Without Accounts

Unlike traditional apps:

• No registration or sign-up required
• Your device gets an anonymous ID (like "a4b5c6d7-e8f9...")
• All health data stays on your device
• Deleting the app permanently deletes all your data
• New device = fresh start (no data transfer)

4. Subscription and Payment

Freemium Model

VitalOS offers free features indefinitely:

• Manual food logging and macro tracking
• Access to community food database
• Basic nutritional analysis
• 3 free AI food analyses per month

VitalOS Pro Subscription

• Unlimited AI food analysis
• Advanced nutritional insights
• Premium features as they're released
• Billed monthly from your signup date (e.g., 15th to 15th)
• Automatically renews unless cancelled

Cancellation

Best Practice: We recommend canceling your subscription before deleting the app for the smoothest experience. You can cancel anytime from Settings → Account Management.

If you've already deleted the app and need help with your subscription, we can still assist you! Contact support@vitalos.app with:

• The email address used for payment
• Your User ID (first 8 characters listed under Profile, e.g., "User 5f3a9b2c")

Cancellations take effect at the end of your current billing period, so you keep access until then.

5. Your Data and Content

Data on Your Device

You have complete ownership and control of all health data on your device. We cannot access, view, use, or retrieve this data. It exists solely on your device.

Community Contributions

If you submit a food to the community database:

• That food data becomes public and available to all users
• It is not linked to you in any way
• You cannot retract community contributions once submitted

Prohibited Conduct

You agree not to:

• Submit false or misleading food data to the community database
• Use the Service to promote eating disorders or unhealthy behaviors
• Attempt to reverse engineer or hack the app
• Use the Service for any illegal purpose
• Upload malicious code or content
• Violate any applicable laws or regulations

6. Intellectual Property

The VitalOS app, its design, and the community food database are our property. The VitalOS name and logo are our trademarks. Your personal health data is your property and remains on your device.

7. Accuracy of Information

Food database entries come from USDA and community contributions. We cannot guarantee accuracy of all nutritional information. Users should verify critical nutritional data independently, especially for medical dietary requirements.

8. Privacy

Your use of VitalOS is governed by our Privacy Policy. Summary: We can't see your health data because it never leaves your device.

9. AI Features and Limitations

• AI food recognition may not always be accurate
• Free users get 3 AI analyses per month
• AI features require internet connection
• Images are processed for analysis then discarded

10. Disclaimers

• The Service is provided "as is" without warranties
• We cannot recover lost data (we never had it)
• We are not responsible for health decisions you make
• The app may have bugs or interruptions
• Nutritional calculations may contain errors

11. Limitation of Liability

To the maximum extent permitted by law, VitalOS shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including loss of data (which we cannot recover), arising from your use of the Service.

12. Indemnification

You agree to indemnify VitalOS from any claims arising from your use of the Service, violation of these Terms, submission of false food data, or violation of any laws.

13. Service Termination

We may suspend service for:

• Non-payment of subscription fees
• Violation of these Terms
• Submission of malicious or false data
• Illegal activity

Note: "Termination" means stopping service to your anonymous device ID. Your local data remains unaffected.

14. Governing Law

These Terms shall be governed by the laws of California, United States, without regard to conflict of law provisions.

15. Dispute Resolution

Any disputes will be resolved through binding arbitration in accordance with the American Arbitration Association rules. Class action lawsuits and jury trials are waived.

16. Changes to Terms

We may modify these Terms. Changes will be indicated by:

• In-app notification when you open the app
• Updated dates at the top of this document
• Revision history below

Note: We cannot email you about changes as we don't have your email address. Continued use after changes are posted constitutes acceptance.

17. Severability

If any provision of these Terms is held invalid or unenforceable, the remaining provisions continue in full force.

18. Entire Agreement

These Terms and our Privacy Policy constitute the entire agreement between you and VitalOS regarding the Service.

19. Special Provisions

Data Loss

You acknowledge that deleting the app, device failure, or software bugs may result in permanent data loss. We cannot recover data we never had access to.

Subscription Orphaning

If you delete the app without cancelling your subscription, you must contact your payment provider directly to cancel. We cannot identify you to help.
