[Interest] Question on qt-google-calendar from Qt-interest

[Igor Grivko]

Hi Harry,

I am glad that you are confident with OAuth2.
Authentication token goes from Google, as it is needed, and the 
application never knows the user's credentials (username and password).

I do not see the reason of creating local server though.

Anyway, thanks for your interest in our work!

Best regards,
Igor Grivko
