Privacy Policy

1. Introduction & Scope

This Privacy Policy describes how Calorie Counter ("we", "us", "our", or "the Application") collects, uses, processes, and protects your information when you use our mobile application on Android devices.

By downloading, installing, or using Calorie Counter, you acknowledge that you have read and understood this Privacy Policy. If you do not agree with our policies and practices, please do not use the Application.

2. Information We Collect

We only collect data necessary to provide and enhance our calorie tracking and AI meal identification services:

A. Information You Provide (Stored Locally on Device)

• Profile & Health-Related Goals: Optional details such as age, gender, height, weight, activity level, target weight goal, daily calorie goal, and macronutrient targets (carbs, protein, fat).
• Food & Nutrition Logs: Meal logs, serving sizes, logged items, custom foods, hydration intake, and streak history.
• User Preferences: Unit preferences (metric/imperial), dark mode preferences, and notification reminder schedules.

B. Camera & Photo Data

• Meal Photos: When you use the AI Food Scanner, the camera captures an image of your dish. The image is temporarily compressed and sent via secure HTTPS to generate instant nutritional estimation. Images are processed ephemerally and are not saved permanently on external servers or linked to your identity.

C. Automatically Collected Technical & Diagnostics Data

• Device & Usage Data: Anonymized app interactions, screen views, session duration, and feature usage collected via Google Firebase Analytics to improve app usability.
• Crash Logs & Performance Diagnostics: Stack traces, operating system versions, device models, and technical error logs collected via Google Firebase Crashlytics to resolve bugs and improve app stability.
• Network Security State: An internal check is performed during AI scans to verify if an active VPN or proxy is connected, strictly for rate-limiting, security validation, and preventing automated API abuse.
• Advertising Identifier (AD_ID): Standard Google Play Advertising Identifier accessed in compliance with Google Play Developer Policies for basic analytics attribution.

3. How We Use Your Information

The collected information is used strictly for the following purposes:

4. Device Permissions & Purpose

To provide its core functionality, Calorie Counter requests the following Android system permissions. You can control or revoke these permissions at any time through your device settings:

5. Third-Party Services & Integrations

We partner with trusted third-party service providers that process technical data under strict confidentiality and privacy standards:

• Google Firebase (Google LLC):
  • Firebase Analytics: Anonymized event and screen usage tracking.
  • Firebase Crashlytics: Crash reports and technical diagnostic logs.
  • Firebase Remote Config: Dynamic app configuration updates and version verification.
  • Privacy Policy: https://policies.google.com/privacy
• Google Gemini AI & Cloud Inference Providers:
  • Processes food images ephemerally over encrypted HTTPS to identify food names, estimated weight, calories, protein, carbs, and fat.
  • Images are transmitted solely for the duration of the recognition request and are not used to build personal user profiles.

6. AI Processing & Image Handling

When you use the AI Food Recognition feature:

1. The image is optimized and compressed on your device.
2. The compressed image is transmitted via TLS/SSL encrypted connection to the AI model endpoint.
3. The AI model analyzes the visual features of the meal, extracts nutritional information (calories, macronutrients, estimated weight), and returns structured data.
4. Once the nutritional response is returned, the transient image transmission is discarded. We do not store, catalog, or share your personal photo library.

7. Data Storage, Retention & Security

We implement comprehensive technical and organizational safeguards to ensure user privacy:

• No User Account Required: You can use the full functionality of Calorie Counter without registering an account, providing an email, or submitting identifying credentials.
• Local-First Storage: Your logs, food items, streaks, and personal metrics are stored in private app sandbox storage on your local device.
• Encryption in Transit: Any communication between the application and external APIs (such as AI recognition and Firebase) uses modern HTTPS / TLS 1.2+ encryption.
• Data Retention: Local data remains on your device until you decide to export, clear, or reset it, or until you uninstall the Application.

8. Your Rights & Data Deletion Controls

We believe you should have complete autonomy over your personal data:

• Export Your Data: You can export your entire food log, profile settings, and daily summaries into an open JSON format at any time directly via Settings → Data & Backup → Export Data (JSON).
• Import Your Data: You can restore previously exported backup files via Settings → Data & Backup → Import Data.
• Clear Food History: You can erase all food logs and daily summaries while retaining your profile goals via Settings → Data & Backup → Clear Food Log History.
• Complete Reset & Deletion: You can purge all stored data, profile settings, streaks, and cached preferences instantly by selecting Settings → Data & Backup → Reset All Profile & Settings or by clearing the app data in Android system settings.
• Uninstalling the App: Uninstalling the app permanently removes all local databases and files associated with the Application from your device.

Under applicable privacy laws (such as GDPR, UK GDPR, and CCPA/CPRA), you have the right to access, rectify, port, or delete your personal data. Because we do not maintain central user accounts, you can exercise all of these rights directly inside the app without needing to submit an external request.

9. Children's Privacy (COPPA & GDPR-K Compliance)

Calorie Counter is intended for general audiences and is not directed at children under the age of 13 (or under 16 in the European Economic Area / UK). We do not knowingly collect, solicit, or maintain personal information from children. If you believe that a child has provided us with personal information, please contact us at nexusplayengine@protonmail.com so we can take appropriate action.

10. Changes to This Privacy Policy

We may update our Privacy Policy from time to time to reflect changes in our practices, app features, or legal requirements. When we make updates, the revised date at the top of this document will be updated. We encourage you to review this Privacy Policy periodically to stay informed about how we are protecting your information.
