Flask data storage in session with javascript or jquery -

i have lot of data (about 30 columns) different html pages store:

1. a string (can retrieved id) randomly generated javascript
2. a form data user input
3. a list of values generated javascript

with flask framework, of sessions done on python file (app.py) itself. possible store data on session javascript or jquery?

you can use web storage. there 2 kinds:

session storage:

maintains separate storage area each given origin that's available duration of page session (as long browser open, including page reloads , restores)

local storage:

does same thing, persists when browser closed , reopened.
