Processing stays on the Mac
Alison processes captured audio frames in memory and does not send them to an app-operated transcription backend.
Downloads are different from uploads
Apple language resources and optional Whisper models may need a one-time download before recognition or translation runs locally.
Text history is still stored data
Caption text and translations remain in Application Support until you delete them; raw audio is not added to history.
