At this time, the short answer is, 'No, there is no option to sync or link progress between two different devices or platforms'.
The (slightly) longer answer is:
Since there is no cloud-saving or back up feature in place at this time, all game data saves and is stored locally to each specific device. For this reason, there is no way to transfer or link that data to a different device (i.e sync iPhone game with iPad, or sync an iPad game to Steam, etc...).
If, however, you have reinstalled the app or upgraded to a new device and would like to have your progress restored, our team can help with this. Check out this article to learn more:
Keep in mind, any progress you make on one device will not sync or be reflected on a different device.
