Data not saved when not connected

Despite reports to the contrary, my data was not saved when my Index v2 scale was offline.

I left the scale offline for a couple months having the understanding that the scale would save the data and simply sync it when I reconnected.
I find this morning that none of the data was saved.  Could someone clarify the situation?  Is the scale just a remote data-collection device for the phone app with no ability to store any data??
Is there any way to recover the data that does exist?

Thanks
