Relffits · Effective June 6, 2026
Relffits ("we", "us", "the app") is a nutrition tracking and fitness application. Your privacy matters to us. This policy explains what data we collect, how we use it, who has access, and your rights.
| Category | Examples | Purpose |
|---|---|---|
| Account | Name, email, user ID, profile photo | Authentication, personalization |
| Health & Fitness | Age, sex, weight, height, activity level, body goals | Calorie/macro calculations |
| Meal Logs | Food descriptions, calories, macros, timestamps, satiation scores, favorites | Nutrition tracking, AI analysis, on-device awareness insights |
| Meal Photos On-device | Photos you attach to a meal log | Visual reference inside the app; cached locally in encrypted IndexedDB |
| Daily Note & Monthly Check-In | Mood selection, short text notes, monthly reflection prompt answers | Personal context shown only to you; encrypted with your profile |
| Apple Health iOS only | Step count, distance (read); calories, protein, carbs, fat, fiber, water (write) | Dashboard display, Health app sync |
We do not collect device identifiers, IP addresses, browsing history, contacts, location data, or any data for advertising or tracking purposes.
Relffits offers optional AI-powered nutritional analysis using Google's Gemini API. This feature requires your explicit opt-in consent.
Photo processing: Meal and menu photos are sent to Google Gemini for real-time analysis and are not permanently stored by Google or Relffits servers. Photos you save to a meal log remain on your device only, cached locally in an encrypted IndexedDB store.
Daily limit: AI use is capped at 20 analyses per day per account (meal logs, adjustments, suggestion refreshes, and restaurant menu scans all count). When you hit the cap, meal logging falls back to manual entry until midnight.
Google processes this data under their Cloud Data Processing Addendum. API data is not used to train Google models. You can disable AI analysis at any time in Settings without losing access to other app features.
Relffits includes an on-device awareness engine that analyzes your meal history to generate personalized nutritional insights, a Food Awareness Score, and contextual decision-moment hints. It also includes a pattern analysis engine that detects behavioral trends in your eating habits, an optional Daily Note (mood log), and a Monthly Check-In reflection sheet.
These features do not use Google Gemini or any external AI service. They rely entirely on published nutritional science (USDA FoodData Central, Holt Satiety Index, AHA guidelines, FDA Dietary Guidelines) applied to your own data on your own device.
All sensitive health and nutrition data is encrypted on your device before being stored in the cloud.
Cloud storage is provided by Google Firebase (Firestore + Authentication), hosted in the United States. Firebase complies with SOC 1/2/3, ISO 27001, and GDPR.
On iOS, Relffits can integrate with Apple Health with your permission:
Active-calorie / exercise tracking is manual entry by default. If you'd rather not see step or distance counts, you can revoke HealthKit access in iOS Settings at any time.
HealthKit data stays on your device and in Apple's ecosystem. We never upload HealthKit data to our servers or share it with any third party, including Google Gemini. HealthKit data is not used for advertising or marketing.
| Service | Purpose | Data Accessed |

| Google Firebase | Authentication, encrypted data storage | Email, encrypted profile & meal data |
| Google Gemini API | AI nutritional analysis Opt-in | Meal descriptions, photos, targets |
| Apple HealthKit | Health app sync iOS / Opt-in | Steps (read), nutrition (write) |
