Privacy Policy

for Moldy (Food Freshness Checker)

Last Updated: October 26, 2025

This Privacy Policy describes how Moldy ("we," "us," or "our") handles information when you use our mobile application. We are committed to protecting your privacy. This app is designed to be fully anonymous and does not collect, store, or share any of your personal information.

1. Data We Do NOT Collect

We want to be crystal clear: Moldy does not collect any personal data.

• No User Accounts: The app does not require you to create an account, log in, or provide any personal information (like your name, email address, or phone number).
• No Personal Information: We do not collect, store, or transmit any personally identifiable information.
• No Location Data: The app does not access, collect, or use your device's location (GPS or network-based).
• No Device Identifiers: We do not collect unique device identifiers (like IMEI, Android ID, or Advertising ID).
• No Analytics or Tracking: We do not use any first-party or third-party analytics, tracking, or advertising SDKs (such as Google Analytics, Firebase, or AdMob).

2. Permissions and Data Processing

Moldy requires two permissions to function. Here is an explanation of why they are needed and how any data is handled.

a) Camera & Photo Library Access (Optional)

Purpose: To provide the core app functionality, which is analyzing the freshness of a food item. You can either take a new photo of your food using the Camera or select an existing photo from your device's Gallery/Photos.

Data Handling:

1. You select or capture an image.
2. The image is sent securely using HTTPS to our backend API for analysis.
3. The API's AI model analyzes the image and returns a freshness classification (e.g., "fresh" or "rotten") and a confidence score.
4. The image is deleted from the server immediately after the analysis is complete. We do not store your photos on our servers.
5. The image is not stored within the app's private storage after analysis.

b) Internet Access (android.permission.INTERNET)

Purpose: Internet access is required to securely send the food image to our backend API for AI analysis and to receive the analysis result.

Data Handling: All communication with our API is encrypted using HTTPS. We use the OkHttp library for this network communication.

3. Third-Party Data Processing

To perform the AI analysis, Moldy uses a backend API.

• Service Provider: Our backend AI model is hosted on Railway.app (US-based servers).
• API Endpoint: https://food-freshness-api-moldy-production.up.railway.app
• Purpose: Railway.app acts as our data processor. It hosts the AI model that receives the image, performs the inference, and sends back the result.
• Data Policy: As the data controller, we have instructed the service to delete all user-submitted images immediately after processing. No images or analysis results are stored or logged on the server. Railway.app may collect standard, non-personal server logs (such as IP addresses) for its own security, debugging, and operational purposes, which is standard practice for any internet server. We do not have access to this data.

4. Data Retention and Deletion

• On-Device: The app does not store your photos or any personal data on your device.
• On-Server: User-submitted photos are processed in real-time and are deleted immediately from the server's memory. They are never written to disk or stored in a database.

5. User Rights

Since we do not collect any personal information or create user accounts, there is no personal data for you to access, correct, or delete. You can revoke the app's permissions (Camera, Photos) at any time through your device's system settings. You can completely remove the app and any associated data by uninstalling it from your device.

6. Children's Privacy

We do not knowingly collect any personal information from anyone, including children. The app's analysis is anonymous and does not store data.

7. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page. You are advised to review this Privacy Policy periodically for any changes.
