The OSS Gadget software itself does not collect information about your use of the software, and therefore does not send such information to any source, including to Microsoft. Nevertheless, our privacy statement is located at https://go.microsoft.com/fwlink/?LinkID=824704.
However, OSS Gadget does make outbound network connections to various locations, including NPM (registry.npmjs.org), NuGet (api.nuget.org), and RubyGems (rubygems.org). These connections are generally unauthenticated and made directly to that service. As such, their privacy policy would apply.
In addition, the health calculator (oss-health.exe) and metadata (oss-metadata) tools use API keys to query GitHub and libraries.io. Since this connection is authenticated, the GitHub privacy policy and Libraries.io privacy policy would apply.
