1. Introduction

Macromotion ("we," "us," or "our") provides a comprehensive nutrition, fasting, and health tracking application. This Privacy Policy explains how we collect, use, and secure your data when you use the Macromotion mobile application (the "App").

By using Macromotion, you agree to the collection and use of information in accordance with this policy.

2. Information We Collect

We collect data to provide accurate TDEE calculations, AI-driven insights, and food tracking features.

2.1. Personal & Health Data (User-Provided)

To power our "Auto TDEE" and "Macro Coach" algorithms, we collect:

• Biometrics: Date of birth, gender, height, current weight, and goal weight.
• Activity Profile: Activity level (sedentary to extremely active).
• Dietary Data: Food logs, water intake, and dietary preferences.
• Fasting Data: Fasting windows, start/stop times, and fasting protocols (e.g., 16:8, OMAD).

2.2. Device & Location Data

Precise Location (GPS): We request permission to access your device's location to localize food search results and deliver location-relevant advertising.

Device Identifiers: We collect your Device ID, advertising IDs (IDFA/GAID), and technical specifications (model, OS version) for analytics and bug reporting.

2.3. Media & Inputs for AI Processing

Camera Images: When you use "Meal Photo Scanning," we access your camera to capture images of food. These images are converted to Base64 strings and transmitted securely to our AI provider. We do not access your Photo Library.

Voice Logs: When you use "Voice Logging," we process the text transcript of your speech.

Chat Messages: We collect the text you exchange with the "AI Nutritionist" and "AI Nutritionist River" features.

2.4. HealthKit / Health Connect Data (Read-Only)

If you grant permission, we read specific data from Apple Health or Google Health Connect (e.g., Sleep Analysis, Active Energy Burned).

Usage: This data is used solely to display metrics in your dashboard and to inform the "Weekly Health Analysis" and "TDEE Algorithm."

Privacy: We do not use HealthKit data for advertising purposes.

3. How We Use Artificial Intelligence (AI)

Macromotion uses enterprise-grade Artificial Intelligence (including Google Gemini Paid Tier) to power the following features:

• Meal Scanning: Analyzing Base64 image data to identify foods and portion sizes.
• AI Nutritionist Chat: Answering your nutrition questions.
• Weekly Analysis: Generating summaries of your sleep, diet, and fasting performance.
• Food Quality Scoring: Analyzing nutritional parameters to assign a "Quality Score" to foods.
• TDEE & Macro Coach: Algorithmic adjustment of your calorie goals based on your weight trends and intake.

Data Privacy in AI:

No Model Training: We use the paid/enterprise tier of our AI providers. Your data (images, chat logs, health metrics) is NOT used to train public AI models.

Stateless Processing: Images sent for analysis are processed and then discarded by the AI provider; they are not permanently stored by the AI provider.

4. Data Sharing & Third Parties

We share data with specific third-party processors to operate the App.

5. Advertising & Tracking

Personalized Ads: We use Google AdMob to serve advertisements. If you have allowed "Tracking" via the iOS App Tracking Transparency popup, Google may use your data to show personalized ads.

Opt-Out: You can withdraw consent for tracking at any time via your device settings (Settings > Privacy > Tracking).

6. Data Retention & Deletion

Account Deletion: You can delete your account via the App settings. This action immediately removes your personal data from our active production database (Supabase).

Backup Retention: While active data is deleted immediately, encrypted database backups may retain your information for up to 30 days before being permanently overwritten. This is a security redundancy and these backups are not accessed for active processing.

7. Health & Safety Disclaimers

Macromotion is NOT a Medical Device.

TDEE & Macro Coach: The calorie and macro adjustments recommended by the App are algorithmic estimates. They do not account for pre-existing medical conditions.

Fasting: Intermittent fasting can be dangerous for certain individuals. Consult a doctor before starting any fasting regimen.

Food Quality Scores: These scores are AI-generated opinions based on nutritional density. They are not medical endorsements of a food's safety.

Eating Disorders: We employ system prompts to prevent the AI from encouraging dangerous behavior (e.g., starvation). However, you are responsible for using the App safely. We do not recommend calorie intakes below medically recommended minimums (e.g., 1200 kcal).

8. Children's Privacy

Age Limit: This App is not intended for children under 13.

Ad Targeting: We have configured our ad settings to NOT treat users as children by default (Child-Directed Treatment: OFF). Therefore, users under 13 are prohibited from using the App. If we discover a user is under 13, we will delete their account immediately.
