It would be very nice. In fact I would love to have this feature for this kind of games. It would expand our ability to play by far and wouldn't cost anything.
I agree with you, KrapfenKringel. This backup function could be a useful mobile application for both IoS and Android platforms. Sometimes it is hard to import all contacts from one device to another one. I met this problem when I bought the new watch and forgot to import my friend's contacts, before leaving the city, so when I arrived, I didn't have his telephone number. Hopefully, I found a good online service annuairespageblanches.com/ that helped me find my friend's telephone number.
