If you need your Refined translated to a language that is not bundled within the app, we can create a translation JAR for you.
In order for the translation jar to work, you need to have the language pack for Jira installed first.
Contact support.refined.com and let us know you are interested in translating the customer-facing parts of Refined.
We will send you a file where you translate the words as you see fit.
Send the the file back to us.
We will create a "translation app", a jar file that contains the translations you provided which you can upload to your Jira via Manage add-ons > Upload file.
