The title is pretty self explanatory.  I would like to be able to take scans of my handwritten notes without the danger of going over my 5 GB data limit.  Although one photo I took was only 1 MB, I might run out of space by adding attachments such as pictures (not of notes), PDFs, Office documents, etc 

If photos/scans of notes taken with the app are included in the data limit, could you consider adding a feature similar to Google Photos where there is an option to backup an unlimited number of high resolution photos?
