What it talks to

k8s-borg's own scripts connect only to what you configure: the Borg repositories, the backup sources and databases, the Kubernetes API and, in agent mode, the Borg UI server. They send no telemetry.

The Borg UI server, when the chart deploys it, contacts Borg UI's own services by default:

• https://license.borgui.com on startup and every 24 hours, for its license plan. Air-gapped installs turn this off with borgUI.licensing.startupSync: false and borgUI.licensing.activationServiceUrl: "".
• https://t.borgui.com/e with the server's error reports (Borg UI 2.4.1 and later). borgUI.errorReporting.enabled: false turns them off.

Analytics and error reports in the browser are a per-user setting in Borg UI. See Licensing and Error reports of the Borg UI server.
