How can I sync eM Client with my Samsung Note 4. I don't use Google calendar? jagarland@comcast.net

Hello Jack,
eM Client is just a desktop application.
So, if you want to sync local data, that is not possible.
If your data (calendar, contacts, etc) is connected to a certain account you can probably use some phone calendar/mail apps to synchronize to your mail server.
