Privacy Policy
Last updated: March 7, 2026
1. Information We Collect
Account Information
When you create an account, we collect your name, email address, and profile photo via Google OAuth or Apple Sign-In through Firebase Authentication.
Health & Nutrition Data
- Food photos (processed by AI, not stored permanently)
- Nutritional data from food scans, barcode lookups, and manual entries
- Daily meal logs and calorie/macro summaries
- Body measurements: height, weight, age, gender, activity level
- Weight tracking history
- Dietary goals and preferences
Device Information
We collect device locale (for unit system detection), push notification tokens, and app usage analytics via Firebase Analytics.
2. How We Use Your Data
- Provide AI-powered food identification and nutritional analysis
- Calculate personalized calorie and macro targets
- Track your daily nutrition and weight progress
- Send meal reminder push notifications at your chosen times
- Process subscription payments
- Improve our AI accuracy and app experience
3. Third-Party Services
DeepPlate AI™ (Food Recognition)
Food photos are processed by our DeepPlate AI™ engine for analysis. Photos are processed in real-time and are not stored beyond the API call. The AI may use web-based data sources to improve results for specific branded or regional products.
Firebase (Google)
We use Firebase for authentication, database (Firestore), cloud functions, push notifications (FCM), analytics, and app security (App Check). Data is stored in Google Cloud servers. See Firebase Privacy.
RevenueCat
Subscription management is handled by RevenueCat. Payment processing occurs through Apple App Store and Google Play Store — we never see your payment details. See RevenueCat Privacy.
Nutrition Data Providers
For manual food entry and barcode lookups, we query the following free databases:
- USDA FoodData Central — U.S. government nutrition database (380K+ foods)
- Open Food Facts — Open-source product database (4M+ products, 150+ countries)
- FatSecret Platform API — Nutrition database (1.9M+ foods). Powered by FatSecret.
- CalorieNinjas — NLP-based nutrition lookup for international dishes
Only the food name/barcode is sent to these services — no personal information.
4. Data Retention
Your data is retained as long as your account is active. Barcode and nutrition lookup results are cached globally (shared across all users) to improve performance — these caches contain only food nutrition data, not personal information.
5. Your Rights
- Access: View all your data within the app (meals, weight, profile)
- Deletion: Delete your entire account and all associated data via Profile > Settings > Delete Account. This permanently removes all meal logs, scans, weight entries, and profile data.
- Portability: Contact us to request an export of your data
6. Children's Privacy
FitDietAI is not intended for children under 13. We do not knowingly collect data from children under 13.
7. Security
We use Firebase App Check (device attestation) to prevent unauthorized access. All data is transmitted over HTTPS. Authentication uses industry-standard OAuth 2.0 via Google and Apple.
8. Changes to This Policy
We may update this policy from time to time. We will notify you of significant changes via the app or email.
