Data Collection and Processing

On-Device AI Processing

• AI processing using on-device models (Qwen 3.5 via llama.cpp) never leaves your device
• No data is sent to external servers when using on-device models
• All data (conversations, diary entries, flashcards, practice sessions) is stored locally on your device using AsyncStorage

Cloud AI Processing (Optional)

• When using Google Gemini API (cloud provider), your messages are sent to Google's servers for processing
• This is opt-in only and requires you to provide your own API key
• Google's privacy policy applies to data processed through their API: https://policies.google.com/privacy

Audio Recording (Whisper Transcription)

• The app requests microphone access for voice-to-text transcription
• Audio is processed entirely on-device using the Whisper model
• Audio recordings are temporary and deleted after transcription
• No audio data is sent to external servers

Image Processing

• Images used in the Image Translator tool and chat vision are processed on-device by the AI model
• Images are resized locally before processing and are not sent to external servers (unless using a cloud AI provider)

Web Content Fetching

• The YouTube Summarizer and Web Article Summarizer tools fetch publicly available web pages to extract text content
• This data is processed locally by the on-device AI model
• No user data is sent to these websites

Device Information

• The app reads device RAM and storage capacity to determine compatible AI models
• This information is used locally only and is never transmitted

Network Access

• Internet access is used for:
  • Downloading AI models (one-time, from GitHub/Hugging Face repositories)
  • Cloud AI API calls (only when cloud provider is configured)
  • Fetching web content for summarization tools (YouTube, web articles)
• No analytics, tracking, or telemetry data is collected or transmitted

Data Storage

• All app data (conversations, tool results, diary entries, flashcard sets, practice history, settings) is stored locally on your device
• Data can be cleared by uninstalling the app or clearing app data in Android settings
• AI model files are stored in the app's private directory

Cross-App Model Sharing

• If you have multiple apps from the Local AI family installed, they may share downloaded AI model files with each other to avoid redundant downloads
• This sharing happens entirely on-device via Android's ContentProvider mechanism
• No data leaves your device during this process

Third-Party Services

The app does not integrate any:

• Analytics services
• Advertising networks
• Crash reporting services
• Social media SDKs

Data Retention

• All data is stored locally and retained until you delete it
• Uninstalling the app removes all associated data

Children's Privacy

This app is not directed at children under 13. We do not knowingly collect information from children.
