Python Dimensions — Privacy Policy
Last Updated: 2026-04-15
1. Overview#
Python Dimensions, developed by QQder339, is a Python programming learning app featuring a built-in Python runtime environment and on-device AI tutor.
In short: We do NOT collect, store, or transmit any of your personal data to external servers.
2. Data We Do NOT Collect#
This app does not collect:
- Personally Identifiable Information (name, email, phone number)
- Location data
- Device identifiers
- Usage analytics or tracking data
3. Locally Stored Data#
The following data is stored strictly on your device and never transmitted externally:
- Learning Progress: Answer records and error tracking across all question types (MCQ, fill-in-the-blank, Parsons)
- Code: Programs written in the built-in IDE
- AI Conversation Logs: Conversations with the AI tutor stored locally
- User Settings: Difficulty preferences, interface settings, etc.
4. Offline AI Features#
All AI features run entirely on-device without network connection:
- AI Tutor: Uses local Large Language Models (LLM) to provide hints and explanations; all inference runs on-device
- Python Runtime: The built-in Python interpreter runs entirely on-device; your code is never sent to any server
AI models require a one-time download before first use (user-initiated); all features work offline after download.
5. Third-Party Services#
This app does NOT use any third-party analytics or advertising frameworks (No Google Analytics, No Facebook SDK, No Ads).
6. Network Access#
Network access is restricted to:
- Downloading AI Models (Optional, one-time): Only connects when you explicitly choose to download LLM model resources
- External Links: Opens browser when tapping relevant links
Other than the above, the app does not initiate network connections. Code execution runs entirely in the local Python environment.
