The best part is, we can use any cloud storage like DropBox or Google Drive to store files which are required for our project as per requirement of clients without taking extra time/costs by using their own server infrastructure! It's very easy & simple way if you want your customer data secure than go with this one!! I have no dislike about it because everything seems good but i would suggest that they should add more features such adding OCR feature etc so people will be happy when working over deep flux toolkit. You dont need additional tools nor servers neither do much efforts needed only just few clicks done here> ;).
