You can configure the widget to be visible in a specific language. This will allow your visitors to get asked “How do they feel?” and following questions in their own language.
All you need to do is going to your dashboard and configure the widget. Select « customize the widget » tab, choose the specific language between the 33 languages available and save it. The widget is automatically updated on your website in the right language. No need to update the JS code or the plugin, all is done atomically for you.
Moreover, you can find the library of questions in your own language by adapting the language (lang=xx) in the url (i.e. : http://www.emolytics.com/main/survey-library.php?lang=fr)
If you want to have multiple languages simultaneously activated on your website (i.e. for a multilingual website), please check this other page: How to customize Emolytics code for multiple language websites?
