On Ubuntu Linux there is an option to sync system calendar with Google Calendar. In order to do that, I need to log in with Google Account.
Unfortunately, it also requires me to grant permissions to some other services which I don't want to use:
As you can see, If I want to sync my calendar, I'm also obligated to grant some entity (that I'm not sure I trust) access to my email, photos, files etc. There is no options in that window that could allow me to modify that.
Are there any tricks I could use to achieve what I want?
