larsiusprime: I just pushed version 1.0.51 to the public update server. This new version has an option to disable the auto-update check.
With this change, if you opt out of data tracking, and turn off the auto-updater, the application should no longer "phone home." If you still detect any outgoing connections with both settings turned off, let me know so I can step through my code and see if I'm missing something.
Just wanted to say kudos for being so responsive to feedback and fan requests - it is really impressive how much extra effort you are putting in here. I'm definitely going to buy the game when my next payday rolls around...
