# App settings

The settings page allows you to configure Model Train Script on your device. These are device-specific settings — for layout configuration (command station, vehicles, automation), see [Profile](/docs/manual/profile.md).

## Profiles

A [profile](/docs/manual/profile.md) contains all information for a specific layout. Model Train Script allows you to create multiple profiles representing different layouts.

From the settings page you can:

* **Select** which profile to use on this device.
* **Create** a new profile.
* **Delete** profiles you no longer need.
* **Export** a profile to share it with others.

Profiles are stored in iCloud and automatically synced across all your Apple devices.

## Automation

This toggle enables or disables the automation engine on this device. With automation disabled, event-based scripts will not trigger automatically, but manual interaction (throttle, accessories) is still fully available.

{% hint style="warning" %}
It is recommended to have automation enabled on only one of your active devices at a time. For Z21 users this is mandatory due to a protocol limitation.
{% endhint %}

## App behavior

* **Haptic feedback** — Enable or disable haptic feedback when interacting with controls like the throttle slider and buttons.
* **Background auto power off** — When enabled, Model Train Script automatically turns off track power when the app goes into the background. This is a safety feature to protect your locomotives if you accidentally switch away from the app.

## Advanced

The advanced section provides additional options:

* **AI Assistant** (Beta) — Enable the built-in AI assistant that can answer questions about your layout and execute actions through a chat interface.
* **File overview** — View and manage the files stored by the app (profile data, sounds, images).
