langify ‑ translate your store

I am trying to reach langify for one week and couldn't get any support. Can anyone say if it is still working or not? I like to install it to my site but if I couldn't learn the prerequirements how can I do that?
Edit : Somehow langify support team didn't receive our email so they respond to our questions after review.

Best support team! This app is a little complicated to understand at first, and a few things could be improved to make it easier to use, but thankfully their support team is SUPER responsive and friendly. They find a solution quickly and efficiently.
