Fade In Access is Fade In's optional service for cloud storage, backup, version history, online editing, collaboration, sharing, and publishing.
It is not required in order to use the downloadable, desktop version of Fade In Professional Screenwriting Software, but it integrates with Fade In for cloud storage of your documents. (Without Fade In Access, the desktop version of Fade In will save your documents to your computer itself.)
You can also use Fade In Access on its own in a web browser on either a computer or mobile device.
The desktop version of Fade In doesn't require any sort of account: you can purchase the full version of the software and use it without "logging in". Fade In Access, however, does require an account to log in either through the desktop software or a web browser.
Fade In Access does not itself include a downloadable version of Fade In.
You can use Fade In Access from any web browser by visiting www.fadeinpro.com/access.
