Nutrition tracking, intelligently done.

1. Overview

NutriLog ("we", "our", or "us") is committed to protecting your privacy. This policy explains what data we collect, how we use it, and your rights regarding that data. It applies to the NutriLog Android application, PWA (Progressive Web App), and any associated web services at getnutrilog.com.

2. Data We Collect

We collect the following categories of data:

• Account information: Your name and email address. If you sign in with Google, your profile photo is also provided via Firebase Authentication. If you sign in with email and password, only your email address and chosen display name are stored.
• Food diary data: Meals, foods, portions, and nutritional information you log within the app — including calories, macros (protein, carbs, fat, fibre, sugar, sodium, cholesterol, potassium, vitamins), meal type, and timestamps. This data is stored in Google Firestore under your account. Custom foods you create are also stored per-account.
• Health & biometric data: Calorie targets, macro targets, body weight, height, date of birth, sex, activity level, and goal type — entered voluntarily by you in the app settings.
• Personal health goals: Up to three free-text health goals you optionally enter in the app. These are included in AI coaching requests (see Section 5).
• App preferences & settings: Theme, carb tracking mode (total vs. net carbs), meal type targets, food database preference, and feature toggles you configure in Settings.
• Subscription & purchase data: Your active subscription tier, plan start and expiry dates, purchase platform (Android or web), and receipt token. This is managed by RevenueCat and synced to your account record (see Section 7).
• Analytics data: App open events and screen view events are sent to Firebase Analytics. These events include a platform identifier (Android or PWA) but are not linked to personally identifiable information beyond your Firebase Analytics installation ID.
• Health Connect data (Android only): With your explicit permission, NutriLog reads from and writes nutrition and weight data to Android Health Connect. See Section 4 for details.
• Camera and images: If you use the barcode scanner or image-based food logging features, the app requests camera access. Images you capture for food logging are sent to Google's Gemini AI for analysis and are not stored on our servers.
• AI prompt data: When you use LOGan (our AI coaching feature), your food diary summary, profile biometrics, and any health goals you have set are included in prompts sent to Google's Gemini API. See Section 5 for full details.

3. How We Use Your Data

• To provide and operate the food diary, AI coaching, and health tracking features of the app.
• To personalise AI coaching responses based on your goals, biometrics, and logged food data.
• To sync nutrition and weight data with Android Health Connect at your direction.
• To authenticate you securely via Google Sign-In or email and password.
• To process and verify subscription entitlements via RevenueCat.
• To understand aggregate app usage patterns via Firebase Analytics, in order to improve the product.
• We do not sell your personal data to third parties.
• We do not use your data for advertising purposes.

4. Health Connect — Permissions

NutriLog requests access to the following Health Connect data types (Android only):

• Nutrition (read & write): To sync your food diary entries to Health Connect and read past records for backfill operations.
• Body weight (read): To read your most recent weight entry from Health Connect when you have not yet entered weight manually in NutriLog settings.

Health Connect data is used solely to provide the sync and backfill features described above. It is never shared with third parties, used for advertising, or accessed beyond what is required. You can revoke Health Connect permissions at any time in your device's Health Connect settings.

NutriLog's use of Health Connect data complies with the Health Connect Permissions Policy.

5. AI Features & Data Sent to Gemini

NutriLog uses Google's Gemini API for three AI-powered features, each of which sends different data:

• AI food search: Your text search query (up to 300 characters) is sent to Gemini to return nutritional estimates for foods not found in the USDA database.
• Barcode / packaging analysis: An image you capture of a nutrition label or product packaging is sent to Gemini to extract the product name and nutritional information. The image is not stored on our servers.
• Meal photo analysis: An image and/or text description of your meal is sent to Gemini to identify foods and estimate macros. Images are not stored on our servers.
• LOGan coaching: Your food diary entries for the current day (up to 50 entries), diary history for the past 7 days, sanitised profile data (goal type, activity level, calorie and macro targets, date of birth, sex, height, weight, carb tracking mode), and up to three personal health goals are sent to Gemini to generate personalised coaching responses.

Data sent to Gemini is processed by Google in accordance with their Gemini API Terms of Service. Under the current API agreement, this data is not used to train Google's models.

AI features require an active subscription or free trial. They are subject to rate limiting (20 requests per user per hour).

6. Camera & Image Access

Camera access is used for two features: barcode scanning (to identify food products by their barcode) and image-based food logging (to identify foods or read nutrition labels from a photo). Camera permission is optional — all other app features work without it.

Images captured in-app are sent to Google's Gemini API for real-time analysis and are not stored on our servers. You may also upload images from your device's photo library for the same purpose.

7. Subscriptions & Payments

NutriLog offers optional paid subscriptions that unlock AI features (LOGan coaching, meal photo analysis, AI food search). Subscriptions are managed by RevenueCat, a third-party subscription management platform.

• Android: Purchases are processed by Google Play Billing. NutriLog does not receive or store your payment method details.
• Web: Purchases are processed by Stripe via RevenueCat. NutriLog does not receive or store your payment card details.

RevenueCat shares your subscription status (tier, platform, expiry date, and a receipt token) with our servers to verify entitlements. This data is stored in your account record in Firestore. For more information, see RevenueCat's Privacy Policy.

8. Analytics & Usage Data

We use Firebase Analytics to collect basic usage data, including:

• App open events (with platform: Android or PWA)
• Screen view events (screen name and platform)
• Standard Firebase auto-collected events (e.g., session start)

This data helps us understand how the app is used at an aggregate level. It does not include the contents of your food diary, AI conversations, or any personally identifiable information beyond standard Firebase Analytics identifiers.

We do not use any third-party crash reporting or error tracking services. Server-side errors are logged to standard output for operational monitoring only.

9. Data Storage & Security

• Your account and diary data is stored in Google Firebase (Firestore and Firebase Auth), hosted in the United States.
• All data is encrypted in transit using TLS.
• Firestore security rules restrict access so that each user can only read and write their own data.
• We do not have access to your Google account password or payment method details.
• The app functions offline for viewing and logging; diary entries are synced to Firestore when an internet connection is available.

10. Third-Party Services

NutriLog uses the following third-party services, each governed by their own privacy policies:

• Google Firebase — authentication, database (Firestore), and analytics
• Google Gemini API — AI coaching, meal analysis, and image processing
• USDA FoodData Central API — food nutrition database (server-side proxy)
• Open Food Facts API — product barcode lookups (public database, no authentication)
• RevenueCat — subscription management and purchase verification
• Stripe — web payment processing (via RevenueCat)
• Android Health Connect — health data sync (Android only)

11. Your Rights

• Access: You can view all food diary data stored in your account within the app.
• Export: You can download your full diary history as a CSV or JSON file from the Settings screen at any time.
• Deletion: You can request deletion of your account and all associated data by contacting us at the address below. We will fulfil deletion requests within 30 days. There is currently no in-app account deletion flow.
• Portability: Your diary data export (see above) is available in standard CSV and JSON formats.
• Withdrawal of consent: You may revoke Health Connect or camera permissions at any time via your device settings. Revoking Health Connect permissions disables the sync feature but does not affect your diary data. Revoking camera access disables barcode scanning and photo logging.

If you are located in the European Economic Area or the United Kingdom, you have additional rights under GDPR, including the right to lodge a complaint with your local data protection authority.

12. Children's Privacy

NutriLog is not directed at children under 13 years of age. We do not knowingly collect personal information from children under 13. If you believe a child under 13 has provided us with personal data, please contact us and we will promptly delete it.

13. Changes to This Policy

We may update this privacy policy from time to time. When we do, we will update the "last updated" date at the top of this page. Continued use of the app after changes constitutes acceptance of the updated policy.
