Anyones dad keeping spreadsheets Excel and folders about other people?

My dad is keeping a spreadsheet where he notes how people congratulate him on his birthday. For example: phonecall, text, social media, card, visit. So, 'he can make sure the balance is right when people are having their birthday. He checks the spreadsheet and choses the same method.' this is a quote; he told me and showed me the spreadsheet.

He also keeps folders. When I was 17, he told me he had a folder on me. With my social media photos and correspondence with my mother after the divorce about me. He would use that, if I ever say something negative about him in public.
