This is why we hope to keep everything running for well over two years. However, all the additional services that are included in Fluenz 3, namely the ability to manage your content through your Fluenz ID, the tracking and syncing functions across all devices, our commitment to keep the program updated to the many changes that are constantly made to the big operating systems, and access to the Fluenz Flashcards, all depend on a considerable ongoing technical effort and an array of costly servers. Follow these instructions to get going: Every single session in Fluenz 3 works offline just like an app in a smart phone, and they will run for as long as your computer runs. After your purchase Fluenz we send you an activation email. As long as you have not logged out, you can close it and then go offline, or turn off your computer, and your sessions will be there. When you close the Fluenz Application make sure not to log out of it.
