You will need to have Internet access in order to download the Plotagon Studio application and updates, and you will need to be online in order to log into the application or to make changes to your account. Once you have logged in, though, you can use the application offline (on a plane or train, for example) for several weeks. If you are planning on traveling and want to use Plotagon while you do not have Internet access, then be sure to log in to the application before you leave. (You can still quit the application, but don’t log out.)
