What nuggets are stored offline on your computer?

Question

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?

Compartmentation combined with good encryption is the bedrock of any good op-sec. Who centralizes every secret in one location and brings it on their person? My most treasured intellectual property is stored in a Veracrypt container inside a flash drive protected with LUKS as a secondary measure. I keep it at home, and only open it on a secure OS (With no malware) preferably not connected to the Internet. I also have duplicated this in as many places as possible in-case one copy gets corrupted, and have memorized the password and don't have it written down anywhere.
