Halo

Privacy

Local-first, including the voice.

Clipboard, notes, settings, speech models, and optional language-model answers stay on this PC. Halo needs no cloud account for the core product.

  1. Clipboard is opt-in

    Clips stay local. Enable history during onboarding or later in Settings → Shelf & Clipboard.

  2. Notes stay on disk

    Notes live under %LocalAppData%\Halo\notes. No cloud account or sync service is required.

  3. Settings are local JSON

    Appearance, shortcuts, display targeting, fullscreen rules, and preferences remain on your machine.

  4. The assistant starts off

    Halo is never always-listening. You explicitly enable Assistant and start each session by face click, hotkey, AI station, or typed command.

  5. Speech stays on device

    Whisper models download to %LocalAppData%\Halo\models and process listen sessions locally.

  6. Answers can stay local too

    Optional Gemma 3 1B handles free-form questions on device. It can be removed whenever you want.

  7. Secrets use Windows storage

    Optional Spotify credentials and secret material use Windows Credential Manager rather than settings.json.

  8. Permissions are requested when needed

    Notification and calendar access are requested only when you use those integrations.
