Halo Privacy Policy

• Short versionHalo runs on your Mac. It does not have accounts, does not collect analytics or usage data, and does not send your audio, cue names or show data to BDM Prod or anyone else.
• Your voiceWhen Listen is on, Halo turns speech into text on your Mac with a speech model built into the app (Whisper, running locally). Audio is processed in memory and is not uploaded. There is no cloud AI in this version.
• Show dataThe read-only HaloSync plugin sends your open show's sequence, cue, executor and group names to Halo on your Mac or local network. Halo uses them only to match what you say.
• What stays on your MacYour settings, cue phrases and folders (in ~/Library/Application Support/BDM Halo), a local activity log, and any PDF or CSV cue sheets you export (Documents/Halo Exports). Delete the Application Support folder to reset Halo.
• Network useHalo sends OSC commands to the grandMA3 address you set, on your local network or the same Mac. If you turn on Phone remote, Halo serves a PIN-protected page on your local network only. Halo does not contact BDM Prod servers.
• PermissionsmacOS asks for Microphone (to hear cue calls) and Local Network (to reach grandMA3 on another computer). You can turn either off in System Settings > Privacy & Security.
• This websiteThe Halo website does not use advertising or tracking cookies. If you send the support or waitlist form, we keep what you send only to reply.
• Changes and contactIf this changes in a future version, we will update this page before that version ships. Questions: email bdmmus@gmail.com or contact us.
