## Privacy
The language server had **opt-in** telemetry that collected usage data and sent it to the development team to help improve the extension. Read our [privacy policy](https://github.com/LuaLS/lua-language-server/wiki/Home#privacy) to learn more. Telemetry was removed in `v3.6.5` and is no longer part of the language server.
