Privacy Policy

This privacy policy describes how VitAmizeMe ("the App", "we", "us") collects, uses, and protects your personal information. By using VitAmizeMe, you agree to the practices described in this policy.

1. Information we collect

Account information

• Email address (used for authentication)
• Display name (optional, user-provided)

Health profile

• Date of birth (used to determine age-based nutrient thresholds)
• Biological sex (used to determine sex-based nutrient thresholds)
• Pregnancy or lactation status (used to adjust DRI values)

Health data

• Health conditions (user-provided, used for interaction detection)
• Current medications (user-provided, used for supplement–medication interaction checks)
• Supplement intake data (products, amounts, timing, frequency)

Usage data

• Barcode scan data (product lookups against OpenFoodFacts database)
• App interaction patterns (for local pattern analysis only, not transmitted to third parties)

2. How we use your information

We use the information you provide to:

• Calculate personalized nutrient safety thresholds based on your age, sex, and life stage using NIH and National Academies DRI reference data
• Monitor chronic exposure patterns through 7-day and 30-day rolling average calculations
• Detect supplement and medication interactions using evidence-based interaction rules
• Generate safety alerts and risk assessments including Dynamic Risk Index scores
• Provide pattern analysis and insights based on your intake history
• Identify supplement redundancy and potential cost savings across your supplement library
• Generate PDF safety reports for sharing with your healthcare providers

We do not use your health data for advertising, marketing, or sale to third parties.

3. Data storage and security

Cloud storage

• Account data and supplement logs are stored in Google Firebase Firestore
• All data is encrypted in transit using TLS
• All data is encrypted at rest using Google's default encryption
• Firestore security rules ensure that each user can only access their own data

Authentication

• Authentication is handled by Firebase Auth using email and password
• Passwords are never stored in plaintext; Firebase Auth handles all credential security

Local storage

• DRI reference tables and interaction rules are cached locally on your device using Hive
• Local cache data contains no personal health information
• Local cache is used to support offline functionality

4. Third-party services

We do not integrate advertising SDKs or third-party analytics platforms beyond Firebase.

5. Data retention

• Active accounts: Your data is retained for as long as your account is active.
• Daily logs: Intake history is retained for historical analysis and chronic exposure calculations (90+ days of history supports accurate pattern analysis).
• Account deletion: When you delete your account, all associated data (profile, supplement logs, daily logs, risk snapshots) is permanently deleted from our servers.

6. Your rights

• Access: View all your stored data through the app at any time.
• Export: Generate a comprehensive PDF report of your supplement data, risk assessments, and safety analysis.
• Deletion: Delete your account and all associated data from the Profile screen within the app. Deletion is permanent and cannot be undone.
• Data export: Export all your data as a structured JSON file through the Profile screen.
• Correction: Update or correct your health profile, medications, and supplement data at any time through the app.
• Opt-out: If future analytics features are added, you will be able to opt out.

For EU/EEA users (GDPR)

If you are located in the European Union or European Economic Area, you have additional rights under the General Data Protection Regulation, including the right to data portability and the right to lodge a complaint with a supervisory authority.

8. Children's privacy

VitAmizeMe is not intended for use by children under the age of 13. We do not knowingly collect personal information from children under 13. If we become aware that we have collected data from a child under 13, we will take steps to delete that information promptly.

Users between 13 and 17 should use the App only with the involvement of a parent or guardian, as supplement use in minors should be supervised by a healthcare provider.

9. Changes to this policy

We may update this privacy policy from time to time. If we make material changes, we will notify you through an in-app notification before the changes take effect. Your continued use of the App after changes are posted constitutes acceptance of the updated policy.
