I don't even remember having setting up one up otherwise I would have saved it in Bitwarden...
So now I've exported all my notes, uninstalled Jopling, reinstalled it... but it's not in a blank state!
All my notes are still there.
What can I do?
EDIT: found the solution here: Confused about encryption password - #4 by grag
To ensure that you remove Joplin completely you will want to delete the ~/.config/joplin-desktop directory. For Windows 10 that would be something like C:\Users\your_username.config\joplin-desktop. The .config is a hidden folder so by default you will not see it listed on Windows. You can change this by opening your file explorer and select “View” -> “Hidden items”.
