 ## Security & Privacy
 
-- Processing in memory; audio is not written to disk by the plugin
-- Audio you record is transmitted to OpenAI for transcription over HTTPS (via Obsidian’s `requestUrl`).
-- API key is encrypted for storage
-
-Note: When Electron SafeStorage is unavailable, the plugin falls back to lightweight obfuscation for the stored key; the plugin is desktop‑only by design.
-
-See also OpenAI’s Privacy Policy.
+- Processing in memory: audio is not written to disk by the plugin.
+- Network use: recorded audio is sent over HTTPS to `https://api.openai.com/v1/audio/transcriptions` via Obsidian’s `requestUrl` for transcription. The settings connection test calls `https://api.openai.com/v1/models`. No telemetry, ads, or self-update requests are sent by the plugin.
+- Account and billing: an OpenAI API key is required, and OpenAI API usage may be billed by OpenAI.
+- API key storage: the API key is stored in plugin settings. When Electron SafeStorage is available, the key is encrypted with SafeStorage before saving.
+- SafeStorage fallback: if Electron SafeStorage is unavailable, the plugin stores the key with a lightweight XOR/Base64 obfuscation fallback for backward compatibility. This fallback is not equivalent to OS-backed encryption.
+- Clipboard access: the Copy button writes only the current transcription text to the system clipboard. If note creation or insertion fails, the plugin may also write that same transcription text to the clipboard as a recovery fallback. The plugin does not read from the clipboard.
+- Vault file access: drafts are saved to, loaded from, and cleared from `<vault>/.obsidian/plugins/voice-input/draft.txt` using Obsidian Vault/FileManager APIs. Insert and append actions write only to the active target note, or create a timestamped `Voice-Memo-*.md` note when no suitable note is available.
+- Local files: optional local VAD reads `fvad.wasm` and `fvad.js` from the plugin folder after you install or choose those files. The release bundle does not include these WebAssembly files.
+- External links: settings may show a link to the fvad-wasm GitHub project for manual download, but the plugin does not download those files automatically.
+- Privacy policy: see [OpenAI’s Privacy Policy](https://openai.com/policies/privacy-policy/) for OpenAI API data handling.

+- Vault ファイルアクセス: 下書きは Obsidian の Vault/FileManager API を使って `<Vault>/.obsidian/plugins/voice-input/draft.txt` に保存、読み込み、削除されます。挿入と追記は対象ノートのみに書き込み、適切なノートが見つからない場合は `Voice-Memo-*.md` 形式のノートを作成します。
