SpecMap only communicates with the server where the extension is installed. This is either Azure Devops or the on-premise TFS server where it is hosted.
All data is stored on this server, and SpecMap does not send nor store data elsewhere.
External network connections are only used by the monitoring functions, which connect to an external Azure Appinsights service. However, this is not required for SpecMap to function. We only collect information on users/and usage, which can help us troubleshoot issues with SpecMap.
