We take security seriously. If you discover a security vulnerability within Vocalinux, please follow these steps:

• Open a public GitHub issue for security vulnerabilities
• Disclose the vulnerability publicly before it's fixed

1. Email the maintainer directly: Send an email to jatinkrmalik@gmail.com with:

   • A clear description of the vulnerability
   • Steps to reproduce the issue
   • Potential impact assessment
   • Any suggested fixes (optional)

2. Use the subject line: "Vocalinux Security Vulnerability Report"

3. Wait for acknowledgment: You should receive a response within 48 hours

1. Acknowledgment: We'll confirm receipt within 48 hours
2. Assessment: We'll evaluate the severity and impact
3. Timeline: We'll provide an estimated fix timeline
4. Fix: We'll work on a fix and coordinate disclosure
5. Credit: If desired, we'll credit you in the release notes

Vocalinux is designed with privacy in mind:

• Offline by default: whisper.cpp (default), Whisper, and VOSK engines all work completely offline
• Local processing: All speech recognition happens on your device
• No data collection: We don't collect or transmit your voice data
• No telemetry: We don't track usage or behavior

whisper.cpp is the default speech recognition engine:

• High-performance C++ implementation
• Processes completely locally on your machine
• Models are downloaded once and cached locally
• No audio data is sent to external servers
• Supports Vulkan GPU acceleration for AMD, Intel, and NVIDIA GPUs

OpenAI's Whisper is also available as an alternative:

• PyTorch-based implementation
• Processes locally on your machine
• Models are downloaded once and cached locally
• No audio data is sent to external servers

The application stores data in:

• ~/.config/vocalinux/ - Configuration (mode 700)
• ~/.local/share/vocalinux/ - Data and models (mode 700)

1. Text injection: Uses xdotool/wtype which may have implications for input monitoring
2. Keyboard shortcuts: Global keyboard hooks require appropriate permissions
3. Virtual environments: Running in a venv provides some isolation

Keep your installation updated to receive security fixes:

cd vocalinux
git pull origin main
pip install --upgrade -e .
