+"""Usage telemetry for the PolyAI ADK.
+
+Copyright PolyAI Limited
+
+Fires a single background HTTP POST for each CLI command so the product team
+can understand how developers use the ADK (command frequency, push volume,
+active users, etc.)
+
+Identity
+--------
+We collect the developer's real name and email address (from git config) plus
+their OS username and machine hostname.  This lets the team track usage at the
+individual contributor level.
+
+Opt-out
+-------
+Set ``POLY_TELEMETRY_DISABLED=1`` (or any truthy value) to suppress all
+telemetry.  Useful for CI/CD pipelines or local overrides.
+
+The call runs in a daemon thread with a hard 2-second timeout and is silently
+swallowed on any error — it *never* blocks or breaks the CLI.
