1. Introduction

AI Calorie Scanner - NutriSnap ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our mobile application (the "App").

Please read this Privacy Policy carefully. By using the App, you agree to the collection and use of information in accordance with this policy. If you do not agree with our policies and practices, please do not use the App.

2. Information We Collect

2.1 Information You Provide

The App allows you to manually enter or edit the following health and fitness information. This data is stored locally on your device and is not transmitted to our servers unless otherwise stated:

• Profile Information: Gender, age, height (cm), weight (kg), activity level, fitness goal (e.g., lose weight, maintain, gain weight).
• Dietary Records: Food names, portion sizes (grams), calorie counts, and nutritional breakdown (protein, carbohydrates, fat, fiber, sugar, sodium, calcium, iron, purine) for meals you log.
• Food Images: Photographs of food that you capture using the in-app camera or upload from your device's gallery for AI analysis.

2.2 Information Collected Automatically

3. How We Collect Your Information

We collect information through the following methods:

• Direct Input: When you enter your profile details, dietary records, or adjust settings within the App.
• Camera & Gallery: When you take a photo of your food using the in-app camera or select an image from your device's gallery. Images are processed by Google's Gemini AI service to analyze nutritional content.
• Automated SDKs: Third-party software development kits (SDKs) integrated into the App automatically collect certain data as described in Section 5.

4. Permissions

Our App requires the following permissions to function properly:

You can manage these permissions through your device settings at any time. Disabling camera permission will prevent the core food scanning feature from working.

5. Third-Party Services & SDKs

We integrate several third-party services to provide core features. Each service processes data according to its own privacy policy:

6. Advertising

Our App displays advertisements through Google AdMob, which uses the following ad formats:

• App Open Ad: Shown when the app is opened or resumed.
• Interstitial Ad: Shown between sessions, with a minimum 60-second interval between displays and a cap of 3 displays per session.
• Banner Ad: Displayed at the bottom of the screen on certain pages.
• Native Ad: Displayed as in-content card ads on the home screen.

AdMob may use your device's Advertising ID to deliver personalized ads. You can opt out of personalized advertising in your device settings (Settings → Google → Ads → Opt out of Ads Personalization).

7. How We Use Your Information

We use the collected information for the following purposes:

• Provide Core Functionality: Analyze food images using AI to identify food items and estimate nutritional content. Track your daily calorie and nutrient intake. Generate personalized dietary advice based on your eating history.
• Improve Our Service: Monitor app performance, diagnose technical issues, and analyze usage patterns.
• Rate Limiting & Abuse Prevention: Track daily scan and advice request counts to prevent service abuse.
• Advertising: Display third-party advertisements.

8. Data Storage & Security

8.1 Local Storage

We use the following local storage mechanisms:

• Room Database (SQLite): Stores your dietary records, scan history, and nutritional data on your device.
• SharedPreferences: Stores your profile information (gender, age, height, weight, activity level, goal), authentication UID, and language preference.

8.2 Cloud Storage

Only rate-limiting metadata (daily scan counts and timestamps) is stored in Firebase Firestore. Your dietary records, profile information, and food images are not uploaded to cloud servers by us — they remain on your device.

8.3 Data Security

We implement appropriate technical and organizational measures to protect your information, including encrypted communications via HTTPS/TLS for all network requests. However, no method of transmission over the Internet or electronic storage is 100% secure. We cannot guarantee absolute security.

8.4 Data Backup

Android automatic backup for this app is disabled (allowBackup="false"). Your data is not included in Android's system backup.

9. Data Retention & Deletion

We retain your data as follows:

• Locally stored data (dietary records, profile, images): Retained on your device until you delete it or uninstall the App. You can delete individual records within the App at any time.
• Firestore rate-limit data (scan counts): Retained for as long as your Firebase anonymous account exists. This data contains only timestamps and counters — no personal information.
• Food images sent to Gemini AI: Google's Gemini API processes images in real-time and does not retain them after analysis is complete.

To delete all locally stored data, uninstall the App. To request deletion of Firestore rate-limit data, contact us at the email below.
