OT but I would love to have a trial to test this before purchasing. But nice product idea I have this kind of issues dealing with my photos and videos.

  > Do you offer refunds?
  Once you download Desktop Docs it's yours forever, so it's non-refundable.

Hum it's not really common to not offer refunds for software licenses. And you might have chargebacks anyways.
