The data is linked to the device by obtaining the ID and other data, but I don't know if it's possible to make a copy of it. The data is stored in two or more locations, namely "/Android/data/com.idle.breaker. game/,“ and the most likely place to find the game is in ”/data/data/com.idle.breaker.game/." Keep in mind that the latter location requires root access. I have not tested transferring data from one mobile device to another, but feel free to test it out, and if you find a way to do so, don't forget to share it so that everyone can benefit from your discovery.
