What stays local
Raw memos, attachments, voice recordings, and the compiled Markdown diary live in a Markdown vault on your device as the local source of truth. You can copy the folder out, open it in Obsidian, or burn it to a USB stick.
What goes over the network
- AI compilation: at 2am the day's raw text (no audio, no images) is sent to your configured LLM provider (OpenAI, DeepSeek, or Aliyun DashScope). You bring your own key.
- Voice transcription: M4A files go to Whisper only if you enable it, and only the audio for that memo.
- Optional cloud sync: when you sign in and enable cross-device sync, memo data and supported attachment files are sent to our private Supabase database and object storage. Transport and storage use provider-managed encryption. This sync is not end-to-end encrypted, so do not treat it as a zero-knowledge vault. Deleted attachment objects have a recovery grace period before scheduled removal.
- Weather + reverse geocoding: anonymous lat/lng to OpenWeatherMap and Apple — never tied to your identity.
What we never do
- Sell your data. There is no ad model.
- Train models on your journal.
- Track you across apps.
- Require an account to capture.
Crash telemetry
Optional Sentry crash reports, opt-in only. No memo content is ever attached.
