Languages

Settings → Languages (/settings/languages).

Bundled locales live under the app lang/ folder (English, Bengali, Chinese, German, Spanish, Italian, Dutch, Portuguese, Swedish, Arabic, Turkish, Romanian, Vietnamese, and others depending on the build).

Edit translations

Open a language. Change strings and Save. Those keys drive $t('…') in the Vue UI.

Add a language

Create: Name and Code (e.g. fr). Then translate keys on the edit screen (and new_item if you add a key).

Defaults

• Site default: Global settings Default language
• Per user: Profile locale
• Session: language selector → /language/{code}

Missing keys fall back to the source English string.
