Exclusive note, calendar, and office applications without a database for some members of the site!

[SenseiiPikaa]

Hello... To elaborate on the title a bit; I have been thinking for a long time about providing some tools that will allow certain members of the site to take practical notes in their panels. As I mentioned; Are there any comfortable solutions without using a database, without the need for coding, in terms of ajax, js, json, cookies, cache, etc.? Also; Is it possible for the notes not to be deleted when the browser is closed or the session is logged out, and to continue from where it was left off in the next session opening...? I would appreciate it if you share the alternatives and solution suggestions you know about this topic, thank you...
