Can I transfer an iOS license to an Android or Windows Phone device?
Unfortunately, paid apps and in-app purchases cannot be transferred from or to another platform.
In case you would change your device to another platform in the future, like Android or Windows Phone, then the license will not work on another platform.
We are bound by rules for developers as well as licensing policies that prevent us from granting crossplatform license transfer from the platform you purchased it for to a different one.
The only way to gain access to paid products on another platform is to buy a license for that specific platform.
