Once a user "buys" an app in the play store, the user can install that app on other devices (free of charge) that also have that same users "google" account registered on it.

If you want to prevent a user from installing your app on other devices that the user owns, then you will need to create your own cloud activation service which will generate a unique authorization code based on the specific devices unique device ID (see other threads on how to generate one) so that the code will only work to "activate" your app on one specific device.
