📦 Installation
⚠️ Windows SmartScreen Warning (Expected Behavior)
First-time users will see a Windows security warning because this application is not yet code-signed with a commercial certificate.
This is normal for new applications. Here's how to proceed:
- When you see "Windows protected your PC":
- Click "More info"
- Click "Run anyway"
- This is a one-time warning
- Your data and system are safe - this is open-source software
Why this happens: We're a new publisher, and obtaining a code signing certificate costs $400-600/year. We're working on getting one for v1.1.0 to remove these warnings.
Your security: All code is open-source on GitHub. The application runs entirely offline with no data collection or internet requirements.

Option 2: NSIS Setup Executable
