# App Preferences

Customize how Crew looks and works for you — theme, language, timezone, notifications, and more.

## Theme

Pick how Crew looks on your screen:

| Option     | What it does                                            |
| ---------- | ------------------------------------------------------- |
| **Light**  | Bright background, dark text                            |
| **Dark**   | Dark background, light text — easy on the eyes at night |
| **System** | Automatically follows your device's light/dark setting  |

Go to **Settings → Preferences** and tap the theme you want. The change applies instantly.

## Language

Crew supports 14 languages. Switch your language in **Settings → Preferences → Language**.

The entire interface — menus, buttons, notifications, and AI responses — switches to your chosen language.

Supported: English, 한국어, 日本語, 中文, Español, Français, Deutsch, Português, Italiano, Türkçe, العربية, हिन्दी, Bahasa Indonesia, ภาษาไทย

## Timezone

Set your timezone so Crew shows the right times for meetings, reminders, and scheduled tasks.

Go to **Settings → Preferences → Timezone** and pick your timezone from the list. Crew auto-detects your timezone on first use, but you can change it anytime.

## Location Sharing

When location sharing is on, Crew can give you local weather, nearby places, and directions without you having to say where you are.

* **On**: Crew uses your approximate location for weather, maps, and local recommendations
* **Off**: Crew won't access your location — you can still tell it manually

Toggle this in **Settings → Preferences**. Your location data is never stored permanently.

## Email Notifications

Control what emails Crew sends you:

* **Insight alerts**: Get notified when Crew finds something important (meeting prep, deadline reminders, etc.)
* **Product updates**: News about new features and improvements

Manage these in **Settings → Preferences → Email Notifications**.

## Desktop App

If you're on macOS or Windows, you can use Crew as a desktop app for quicker access.

* **Already using the desktop app?** Tap "Open App Settings" to manage desktop-specific options like startup behavior
* **Using the web version?** You'll see a download button — grab the app for a more native experience

## Connected Devices

See all the devices where you're logged into Crew — phones, tablets, and desktop apps.

* View device name, platform, and when it was last active
* **Revoke access** to any device you no longer use or don't recognize

This is a good security habit — check occasionally and remove devices you don't use.

## Account Deletion

If you ever want to leave, go to **Settings → Preferences** and scroll to the bottom.

* **Delete Account** permanently removes all your data — conversations, files, connections, and settings
* This action cannot be undone
* You'll be asked to confirm before anything happens
