Ask HN: What nuggets are stored offline on your computer?

I just watched Hikaru's latest analysis of the current ongoing chess drama regarding OTB cheating. There he nearly revealed by accident some of his personal files and analyses while opening his chessbase database during the stream.

This made me think and I realized that I also have some proprietary stuff (specific data format descriptions and code snippets mainly) that are presumably _valuable_, in any case definitely worthy for my job/business.

So, I'm curious: How does it look for you? Would you be ruined in case someone got access to your personal files, or are we living in a post-privacy world by now in this regard?
