Your little bit of research should have been a little bit more, but I guess that's where this thread comes in :P
Don't dismay, saving and loading information is entirely possible with C2 using WebStorage. Don't let the name fool you, though, you can use WebStorage with offline apps, too, including Node-Webkit (desktop) and CocoonJS (iOS/Android).
Everything is covered in the manual entry
, and here
is a super basic example I made for another user recently.
Oh, I see that you have already seen WebStorage. Then what you want is "local", not "session" storage. That's possible too as you can see in my example.GeometriX2013-02-17 21:18:40
