I have tax, bank, and insurance documents on my computer, and Im doing my best to conform to the "iPad as a main computer device" to rid myself of a laptop. All my other documents are in iCloud/Box/Dropbox, but I don't trust these sensitive documents there. I can easily get these documents on my iPad via iTunes sync, but the question is if I were to do the iCloud backup, wouldn't that sensitive information end up in iCloud anyway? I can't think of a good way to store and backup these documents securely. What service/process do you use to store such information online?
