data management in 3 steps ;)

1. Data taken from a localStorage when the page is opened,
   further get Data from the server // if(Server != localStorage)

2. Further interaction with Data occurs only with state and localStorage.

3. Fresh Data sending in moment page refresh or close.

P.s. later is will need synchronization,
I'm thinking of implementing this on websockets
