I have other people use my computer from time to time, but not for enough time to warrant a separate account. From what I understand, Joplin's data is also stored unencrypted on disk. I don't use full-disk encryption and I don't want to use it just for Joplin. Are people using my computer going to open up my notes app or snoop around in the sqlite db? Probably not. But I like to have the peace of mind.
