Viber's sticker bought will be owned once or permanently? On my Android smartphone Google Samsung Galaxy, I install Viber app and intend to buy a sticker.

My question is whether I will have to re-buy the same sticker on another phone (using the same Google account of course) or it will automatically restored?
Stickers can be synced to other devices. So YES, it's permanent.
