Agent, since you are playing on a Kindle I do not know if it functions like the Android's or the Apple's for tracking your progress.

With Android's, if you log into the game with your Google credentials it tracks them under a thing called Achievements. In there you can get a pretty good idea when you started playing the game by seeing when your first achievement was accomplished..

With Apple's, if you log into their Game Center it is pretty much the same but not as organized as the Android system.
