Well OK, but . . .
email, password - for an ideaplaces account; this doesn't seem in any way unusual
evernote access - you want them to show you your evernote notes, right? Seems like they would have to get this access
dropbox access - only if you want them to also show photos stored in your dropbox on the map, sounds interesting but I haven't done this
photos/contact access - only if you want them to show these on the map as well, I didn't do this either
your location - can't answer "near me" questions without this, yes? Even then this is optional as well
I think there are plenty of apps that ask for too much access, but this seems pretty reasonable given the feature set.
