Privacy Policy for CodeMateX

Last updated: September 2026

Welcome to CodeMateX ("the App"), developed by Liquid Labs Inc. Your privacy is our highest priority. This Privacy Policy describes our practices regarding information collection, usage, and disclosure when you use CodeMateX on Android.

1. Zero Cloud Data Collection

CodeMateX is built from the ground up as a 100% on-device AI application:

• Your AI Prompts and Conversations: Any questions, prompts, and chat sessions you submit to the AI tutor are processed entirely on your physical device hardware using local on-device runtimes (such as Google LiteRT-LM).
• No Cloud AI Inference: Your queries and AI conversation history are never transmitted to external servers, cloud AI APIs, or third-party inference backends.
• No Account Required: The App does not require registration, login, email addresses, or usernames.

2. Local Device Storage

All chat history, topic configurations, and downloaded on-device model weights are stored locally in the App's sandboxed private storage (Room Database and local device filesystem).

• You have full control to inspect, export, or permanently delete individual chat sessions or all saved data at any time from within the App.
• Uninstalling the App permanently removes all locally stored data from your device.

3. Network Usage

The App requests standard network permissions (INTERNET and ACCESS_NETWORK_STATE) exclusively for the following optional features:

• On-Device AI Model Weights: Downloading public, open-source model weights (such as Gemma, Qwen, or Phi-4) directly from verified repositories when explicitly initiated by the user in the Model Manager.
• Network State Monitoring: Checking connectivity status to prevent partial downloads on metered connections and automatically adapt the app into offline reading mode when disconnected.
• Optional In-App Code Execution: When a user explicitly taps "Run Code" on a lesson snippet, that code snippet is transmitted via encrypted HTTPS to an execution sandbox proxy (code-playground.gohk.xyz or the official Kotlin Playground API) solely to compile, execute, and return standard terminal output. No personal data, user accounts, telemetry, or AI conversation prompts are attached, logged, or retained.

The App does not integrate any third-party analytics trackers, advertising SDKs, or remote diagnostic telemetry.

4. Third-Party Services & Links

The App does not sell, rent, or monetize your personal data. If the App provides links to external documentation or source code repositories, visiting those third-party sites is governed by their respective privacy policies.

5. Children's Privacy

The App does not collect any personal information from any user, including children under the age of 13. All data remains strictly on the user's personal device.

6. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. Any changes will be reflected with an updated date on this page.
