Unlike Swiftkey, Swype doesn't force to you to give them full access to all your keystrokes to use the core swiping functionality. If you've chosen Swiftkey for no other reason than it was free I encourage you to switch to Swype today if you are at all concerned about privacy, either personally or in principle. If you want to go the extra step, consider writing Swiftkey a message explaining your switch to encourage them to change policy. http://swiftkey.com/en/contact/
