+# Settings and Data
+
+Settings control the app, voice, plugins, servers, themes, updates, local APIs, and desktop behavior.
+
+## Common Settings
+
+| Area | What you can manage |
+| --- | --- |
+| Account | Current profile, display details, and avatar metadata. |
+| Voice | Devices, volumes, bitrate, latency, noise reduction, screen share preferences. |
+| Plugins | Installed plugins, capability grants, plugin logs, and plugin store sources. |
+| Server | Server details, channels, roles, moderation, plugin requirements, and member controls. |
+| Theme | App colors and visual preferences. |
+| Desktop | Tray behavior, auto-start, hardware acceleration, updates, and local data tools. |
+| Local API | Local HTTP server, API docs, Docusaurus docs, and allowed signaling servers. |
+
+## Local Data
+
+Desktop MetoYou stores local app data on your device. That can include rooms, messages, users, plugin data, settings, and metadata. The desktop settings include data import/export tools.
+
+## Local API and Documentation Hosting
+
+The desktop app can start a local HTTP server. It is off by default. When enabled, it can serve:
+
+- Local REST API endpoints under `/api/...`;
+- Scalar REST API docs at `/docs`;
+- this Docusaurus site at `/docusaurus`.
+
+Authentication for protected local API routes uses a local bearer token. Login is checked against an allowed signaling server that you configure in settings.
