I've noticed that your data is not preserved in the account like your SQL workspace (code) or your notes.

I've recently solved the first 5 cases. This was on my laptop, I was logged in.
Today I wanted to "continue" and maybe refactor some of my code. But all code and notes are missing.
I checked on the laptop, there I can see them.
So my guess is, that the data is only persisted in the browser (local storage for example).

Could we persist that in the account data, too?
I think it would be great to come back later to review or maybe share your solution with other detectives.

At the least I would recommend adding a warning/notice what data is saved and what not.
