Privacy Policy

Last Updated: March 4, 2026

1. Introduction

Welcome to WellFit ("we," "our," or "us"). We are committed to protecting your privacy and ensuring the security of your personal information. This Privacy Policy explains how we collect, use, and safeguard your data when you use our mobile application.

2. Information We Collect

2.1 Information You Provide

Profile Information: Age range, biological sex, height, weight, activity level, fitness goals, diet preferences, and equipment access
Food Log Data: Food names, nutritional information, meal types, timestamps, and optional food photos
Weight Tracking: Weight measurements, dates, and optional notes
Workout Data: Completed workouts, exercises, sets, reps, and weights (when logged)
Water Intake: Daily water consumption logs
Apple Health Data (Optional): If you enable Apple Health sync, the app reads active calories, step count, and weight entries from Apple Health, and writes weight, height, nutrition, water intake, and workout data to Apple Health. All syncing happens locally on your device. You can enable or disable individual data categories at any time.

2.2 Automatically Collected Information

Device Information: Device type, operating system version, app version

We do not collect analytics, usage data, crash reports, or any other automatically gathered information beyond what is strictly necessary to operate the app.

2.3 Photos, Camera Access, and Barcode Scanning

When you use the food recognition or barcode scanning features, we request access to your device's camera and photo library. Photos are:

Stored locally on your device only
Never uploaded to our servers
Sent to Google Gemini AI when you use the AI photo scanning feature (see Section 5.1)

The app offers two food recognition modes:

Cloud AI recognition (Google Gemini) — online: Sends a photo to Google's Gemini API for food identification and nutrition estimation. Used automatically when you are connected to the internet and tap the photo scan button.
On-device recognition (Apple Vision) — offline fallback: Uses Apple's Vision framework, which runs entirely on your device. Used automatically when you have no internet connection. No photo or data leaves your device. Offline scans do not count against your daily limit.

No API keys or account credentials are required from you. WellFit uses its own developer API credentials to access these services on your behalf.

When you use the barcode scanner:

The camera is used to detect barcodes on food products
No images or video are stored — only the decoded barcode number is used
The barcode is sent to Open Food Facts to look up product information (see Section 5)

2.4 Apple Health (HealthKit)

If you enable Apple Health integration in Settings, the app accesses HealthKit data on your device. This includes:

Data written: Weight, height, nutrition (calories, protein, carbs, fat, fiber, sugar, sodium), water intake, and completed workouts
Data read: Active calories burned, step count, and weight entries from external sources (smart scales, other apps)

All HealthKit data is exchanged locally between WellFit and Apple Health on your device. It is never sent to our servers or any third party. You can enable or disable individual read and write categories at any time in Settings → Apple Health.

3. How We Use Your Information

We use the collected information to:

Provide personalized nutrition plans based on your profile
Generate custom fitness programs tailored to your goals
Track your daily nutrition intake and progress toward goals
Display analytics and trends about your health data
Provide customer support when requested

4. Data Storage and Security
