I would like to create a document with all of my credit card info, banking info and passwords. I need to be able to access this document from my Ipad, Android cell phone and any computer with an internet connection. I am somewhat concerned about someone getting this information without my approval. The info will be saved on Word document. How safe am I using a program like Dropbox? Can this file be encrypted before uploading to a program like Dropbox? Any suggestions are much appreciated!
