It reads like you mistook Realm Works for a VTT.

A VTT provides the messaging and instant reveal to players during game sessions.

Players can use the information revealed during previous game sessions: either at the start of the game session, or during a game session to look back and find out some information that they discovered several sessions ago but can't remember.

"Cloud" is a such a current buzzword that is is many things to many people. Dropbox allows file to be stored in the cloud, but they don't allow multiple people to be editting the file at the same time.
