Saving state of app

Hi i new to Framwork 7 and I am enjoying it.

I wanted to know how to save the state of app, like settings (Font type, font size) so the next time we open an app, it is loaded with the saved settings. Thanks

Use LocalStorage which is a Html5 feature.
Also, you can use package like lowdb.
