I have a new Android device and I had purchased SharePlus PRO with my older one. Now I want to install SharePlus in my new device but I don't want to be charged again. What can I do?
The SharePlus app you purchase is attached to your Google ID/Account. In order to install SharePlus in another device without being charged for it, you need to associate that device with the same Google ID you used to purchase SharePlus the first time.
If you try to install SharePlus using another ID you will be charged.
For more information on retrieving previously purchased applications please refer to this article on Google Play Help:

I hope this helps.
Take care,
