I've recently seen third-party apps like Smultron and iA Writer mentioning in their Mac App Store descriptions that they support iCloud syncing.
Are the files saved to iCloud via these apps accessible from icloud.com? How do they appear? Are they downloadable to e.g. a PC for which the app that saved the file is unavailable?
I'm asking whether or not I am able to access the files with my credentials from (any) web-terminal, all foil hats aside.
