With a custom development budget anything is possible, but it is not currently a feature to edit the language file on our end, we would need to build that. I would estimate a good 30-40 hours of development to translate every string in the app and allow an editable language file. Please contact us through our quote request form if this is something you are interested in providing a development budget for.
I would expect later in 2018 we will reach translation on our own roadmap.
Thanks
