Cloud Syncing across different devices

[Verl4ssener]

Describe your suggested feature

I think it would be cool if there was a cloud Syncing (with for example Google drive or discord) solution so you can read on different devices and sync progress. Something like that was also done by similar manga readers like TJ2k, Komikku or Animiru (anime app but you get the point).
