Why does 2Do connect to amazonaws.com on the Mac?

2Do uses Crashlytics from Twitter in order to keep track of real-time crash reports, something Apple does not provide us with. Apple’s crash reporting is also very unreliable, and several times misses out on frequently crashing 3rd party libraries. Twitter’s Crashlytics is used and trusted by millions, as it gives us real-time crashes along with enough information to fix the problem immediately. No personal information, whatsoever is sent over the wire.
