Have on my notebook Windows 10 and on my Android phone the calendar S: Planner.
My question is, which calendar is compatible with s.planer so that I have the data
from the phone to notebook and vice versa can load?
As far as I know, the S-Planner is based on Google if it has a Google Account or can communicate with it.
And you can access your calendar from the Google Account on the notebook with Google Chrome.
