"Sensitive" data???

I have a long list of ‘sensitive’ data that ‘NEEDS’ to be protected according to the app. This includes my family tree, a rough draft of one of my novels, a PDF of a method book that is openly available, some transcriptions of jazz solos, and a couple of published short stories.
I just wonder what tags an item as ‘sensitive’. Just being on my hard drive and having my name on it really should not qualify.
