# Set appearance and notification preferences

> Choose a display theme and control how K16 sends optional notifications.

## Change appearance

Open your account menu and use **Theme** to choose **System**, **Light**, or **Dark**. **System** follows your device preference. Confirm that the page changes to the selected appearance.

## Change language

In your account menu, open **Language**, search for a language, and select it. Wait for the interface to update. If K16 reports that a translation is still being prepared, follow the displayed prompt; the menu continues to show the confirmed language until the change is applied.

## Change notifications

Open **Settings** and select **Notifications**. Each row represents a notification category and each column represents a delivery channel.

<Steps>
  <Step title="Find a category">Review the category description before changing it.</Step>

  <Step title="Toggle a channel">
    Turn the available in-app or email channel on or off. K16 saves each change immediately.
  </Step>

  <Step title="Confirm the saved state">
    Check the saved timestamp shown above the preference grid.
  </Step>
</Steps>

<Note>
  Required account and security notifications remain enabled. You cannot disable them from the
  preference grid.

## Change cookie preferences

Open your account menu and select **Cookie preferences**. You can also open the cookie preferences page and select **Open cookie preferences**.

1. Review the optional categories available in your workspace.
2. Change individual switches, or use **Reject all** or **Allow all** for optional categories.
3. Select **Save preferences**. After the dialog closes, reopen it to confirm your choices.

**Required** cookies remain **Always on** because they support sign-in, security, and core functionality.
