Did you purchase on Google Play?
---
Google will store your purchase on their servers, forever.
If/when you switch or reset your device, please configure it with the same @gmail.com account as you originally used to to purchase the unlocker.
This will make my unlocker and other previously purchased apps show in Google Play app (under My apps) as “purchased”, so you won’t have to pay again. You can use the unlocker on multiple devices the same way, by configuring them all with the same @gmail.com account.
