Fast Java Thread is a fully offline desktop application. It does not:
- Collect any user data
- Send any data over the network
- Use analytics, telemetry, or tracking
- Load any external resources (CDN, fonts, scripts)
- Require an internet connection to operate
All thread dump analysis is performed locally on your machine. Your data never leaves your computer.
The optional MCP server runs entirely on your local machine. When using HTTP transport, it listens only on localhost and is not accessible from other devices. No thread dump data is transmitted externally — MCP clients connect to the local server and all processing stays on your computer.
