I like the functionality but the permissions scare me. After writing a spec for a new product using this app I re-read the permissions and apparently the maker of the app can "View, modify, and share with other users documents that this application has been installed in". Possibly I'm misinterpreting it, but it sounds like to me that the maker can read, copy, and share any document that was created using their app.
How can I trust something like that with a new product spec?
