# Themes and language

YouDesign Freelucy adapts to how you like to work. Switch the theme and the interface language from the header, on any page.

## Light and dark theme

Use the **theme toggle** in the header to switch between light and dark. The whole interface follows, including the editor canvas in every view.

{% hint style="warning" %}
🖼️ **Screenshot needed — `v26-theme-toggle.png`** The header theme toggle, with the editor shown in dark mode.
{% endhint %}

{% hint style="info" %}
**Exports follow your theme.** If you export an image while in dark mode, the image comes out dark. Switch to light first if you want a light export.
{% endhint %}

## Language

Use the **language switcher** in the header to change the interface language. Freelucy ships in 10 languages:

|              |              |            |
| ------------ | ------------ | ---------- |
| English (US) | English (UK) | German     |
| French       | Spanish      | Portuguese |
| Hindi        | Bengali      | Turkish    |
| Japanese     |              |            |

{% hint style="warning" %}
🖼️ **Screenshot needed — `v26-language-switcher.png`** The header language switcher open, showing the available languages with their native names.
{% endhint %}

Freelucy detects your browser language on first use and matches it if it is supported. If your language is not available, the interface falls back to English (US). You can override the choice anytime from the switcher.
