What is the voucher?

A voucher is a code that you can redeem to get the Pro+ version on Android. There are two types of voucher:

1. Public voucher: the same code can be redeemed by many people, but it has an expiry date.

2. Personal voucher: it does not have an expiry date, but one code can be used only once by one user.

Unfortunately, voucher is only works for one time installation at present. Hence, please note that the pro+ version will disappear once you uninstall the app or you change your device
