Save / loading game data

I'm trying to understand the ROAR engine. According to what I've been reading it sounds like ROAR engine can save/load encrypted data. I was thinking I would need to build a SQL server to maintain private user data for my game but now I'm thinking this ROAR engine could be a solution that is much more robust than my own! Is ROAR engine capable of saving a scene and all the associated game data variables in that scene for a given user? What I mean is, is ROAR capable of saving and loading encrypted data on the local machine the game is run on? Or do I need to build that system myself? If ROAR is a complete solution for saving and loading encrypted player data, what happens if a user doesn't have internet access but would still like to load his or her saved game? Does ROAR account for this scenario? Thanks for any help you can provide!
