Synchronizing Sky Force 2014 over two devices

Synchronizing Sky Force 2014 over two devices - Aerobatics performing by modern military aircraft in cloudy sky

I use Sky Force 2014 on two different Android devices A and B. After using Sky Force 2014 on device A, how can I retrieve the progress on device B? I can connect to Facebook and Google if needed. I'd also be interested in synchronizing with my 3rd device, which runs on iOS.
