Privacy Policy for OnlineGDB Mobile

Last Updated: March 8, 2026

Introduction

OnlineGDB Mobile ("we," "our," or "the App") is a professional code compiler supporting various programming languages. This Privacy Policy describes how we handle information when you use our mobile application.

Information We Collect

1. Information Stored Locally on Your Device

The following data is stored locally on your device using SharedPreferences and is never transmitted to our servers:

• Code Snippets: Your saved code snippets, including code content, titles, and associated programming language
• App Preferences:
  • Last selected programming language
  • Theme preferences (dark/light mode)
  • Editor theme selection
  • Font size settings
  • Debug log preferences
• Code Editor State: Your current code, stdin input, compiler flags, and command-line arguments during active sessions

This data remains on your device and is deleted when you uninstall the app.

2. Information Transmitted During App Usage

Code Compilation Data

When you compile and run code, the following information is transmitted to the OnlineGDB compiler server:

• Your source code
• Selected programming language
• Standard input (stdin) data
• Compiler flags
• Command-line arguments
• Input method preference (text or interactive)

This data is transmitted solely for the purpose of code compilation and execution.

App Updates

The app periodically checks for updates by sending:

• Your current app version
• Platform type (Android, iOS, or macOS)

This is sent to our update server to determine if a new version is available.

Analytics Data (Mixpanel)

We use Mixpanel, a third-party analytics service, to understand app usage and improve user experience. The following information may be collected and transmitted to Mixpanel:

• Device Information: Device ID (a unique identifier for your device), device model, operating system version, and app version
• Usage Analytics: App events such as feature usage, screen views, and interaction patterns
• Technical Data: Session duration, crash reports, and performance metrics

This data helps us understand how users interact with the app and identify areas for improvement. Mixpanel's data practices are governed by their own privacy policy, available at https://mixpanel.com/legal/privacy-policy/.

How We Use Information

The information handled by our app is used solely for:

1. Code Compilation: Processing your code through the OnlineGDB compiler infrastructure
2. App Functionality: Maintaining your preferences, saved snippets, and editor settings locally
3. App Updates: Notifying you of available updates to improve functionality
4. User Experience: Remembering your language selection, theme, and editor preferences

Data Sharing and Third Parties

OnlineGDB Compiler Server

Your code and compilation parameters are transmitted to the OnlineGDB compilation server for processing. This is essential for the app's core functionality. The code transmission is temporary and used only for compilation.

We use Mixpanel for app analytics. Mixpanel may collect device identifiers and usage data to help us understand app performance and user behavior. For more information about how Mixpanel handles data, please visit their privacy policy at https://mixpanel.com/legal/privacy-policy/.

External Links

The app may contain links to external websites (e.g., LinkedIn profile, app store pages). We are not responsible for the privacy practices of these third-party sites.

Data Security

We implement appropriate security measures:

• All network communications use secure protocols
• Code transmitted for compilation is sent over encrypted connections
• Local data is stored using platform-standard secure storage mechanisms (SharedPreferences)

Data Retention

• Local Data: Persists on your device until you delete the app or manually clear the data
• Compilation Data: Temporarily processed during compilation

Your Rights and Choices

You have complete control over your data:

• Delete Saved Snippets: You can delete individual code snippets at any time through the app interface
• Reset Preferences: Clearing app data will reset all preferences to defaults
• Uninstall: Uninstalling the app removes all locally stored data
• Offline Use: The app requires internet connectivity for code compilation but stores your snippets and preferences locally

Children's Privacy

OnlineGDB Mobile does not knowingly collect any information from children under the age of 13. The app is designed for learning programming and is suitable for all ages, but we do not target or market to children specifically.

Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Any changes will be reflected by updating the "Last Updated" date at the top of this policy. We encourage you to review this Privacy Policy periodically to stay informed about how we are protecting your information.

Your continued use of the app after any changes to this Privacy Policy indicates your acceptance of the updated policy.
