Field notes
The page says there are no accounts or telemetry, but Jev decision requests—including harness-computed game-state text and options—go to api.typesafe.ai. Source code or frames that the coding agent reads may also go to its own provider. On Windows, the documented sandbox fallback can read local files and reach the network; the run log is said to identify when that fallback is used.
