The Terms page goes to "Jaggi Enterprises", "A Modern Investment Fund. We buy, build, and invest in software companies with recurring revenue.". So maybe this is not really something a guy built for his wife, but some anonymous startup that googled "Which terms rank best on Hacker News" and then wrote the "I did ... my wife .." story?
Jaggi is a fake it until you make it fake portfolio. Most of the companies it runs are just lorem ipsum fake sites. I think it is likely true that this is a solo dev.
Then why would the terms and privacy links go to Jaggi?
