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

[SenseiiPikaa]

Hello... To elaborate on the title a bit; I have been thinking about providing some tools to certain members of the site to enable them to take practical notes in their panels for a long time. As I mentioned; Are there any comfortable solutions available 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 in case the browser is closed or the session is logged out, and to continue from where it was left off in the next session? I would appreciate it if you could share the alternatives and solution suggestions you know about the subject, thank you...
