Settings explained

This page maps the main app settings to what they do in practice.

Appearance​

  • Theme mode: follow system, or force light/dark.
  • Theme style / palette: changes color style and surface tone.
  • Language: follow system, English, or Simplified Chinese.

Security​

  • Auto lock: requires app unlock before reading content.
  • System unlock (platform-dependent):
    • Mobile: biometric unlock
    • Desktop: Touch ID / Windows Hello (where available)
  • Lock now: immediately returns to unlock screen.

Intelligence (Ask AI / search / media)​

  • Ask AI source: Auto, SecondLoop Cloud, or BYOK.
  • Embeddings source: Auto, Cloud, BYOK, or Local runtime.
  • Media understanding source: Auto, Cloud, BYOK, or Local capabilities.

Auto generally prefers Cloud first, then BYOK, then local fallback when needed.

API keys (BYOK) settings​

  • AI profiles (Ask AI): supports provider presets and custom endpoint/model.
  • Embedding profiles (semantic search): currently OpenAI-compatible profile format.
  • Saving a profile as active makes it the default profile used by that capability.

See also: BYOK formats and setup.

Media understanding settings​

  • Document OCR: on/off, language hints, PDF auto page limit, OCR DPI.
  • Audio transcription: on/off, engine choice, and API source behavior.
  • Image captions / image search data: provider mode and mobile data policy.

Sync settings​

  • Choose sync method, auto-sync behavior, network policy, and recovery passphrase.
  • Includes manual push/pull actions and media upload/download controls.

See also: Sync methods.

Desktop behavior​

  • Start with system: launch app after system sign-in.
  • Silent startup: start in background without opening a window.
  • Keep running in background: close-to-tray behavior instead of full quit.
