New Commer

I bought a BOOX tablet mainly because I can link it to Google Drive and have all my PDFs hosted on my G-Drive and do not have to pay any subscription.

If I change to ReMarkable, due to Boox access to Google drive being removed, would I need to pay that ReMarable online subscription to have access to my G-Drive and work with my pdfs?

Also if I do take notes where would it save my notes? Can I have it save it to G-Drive as well?

TLDR : Do I need some form of subscription with Remarkable or not? I really do not want to subscribe.
