Saving Method by NoteApp

Developers
#1

By chance I came over a piece of very small code (css+js+html)
creates and saves notes in an html page! (it is very basic)

I noticed the saving works in the same browser!

-is the saving method is just using local storage?
-is there anything useful for saving TW?

#2

Yes, looking at the code,the calls are to window.localStorage

#3

Thanks @boris, so it has nothing for saving TW!
