Sync progress automatically across devices on GDSchool accounts

**Describe the solution you'd like**
could you please add a way for us to sync data acroos device and web i.e through gdrive backups or simply login in wiht the account used to buy courses on gdquest . this also can be used to add more content to the app via a paywall.

i am wanting ot get into this during school but i want to be able to finish it at my dev setup at home could it be possible or is it already implemented
