Whatever language is set on your WordPress store is what the plugin uses. For instance, if the site is in German, the German translation file is what the plugin will use.

We do not have translation files for some of the languages yet, so in some cases, you may need to translate yourself.

You can use any of these plugins: WPML, Loco Translate, or Codestyling  for your translation, as our plugin is compatible with them.
