There is one external tracker - Google Analytics. But blocked obvs if you use uBlock etc...
I also designed and built this site in 2016 - over half a decade ago and it still looks and feels modern. It's an interesting look at how web design trends have slowed down from how things went from 2000-2010 to 2014-Present.
Clean, to the point, light, crazy fast, zero bloat, no external trackers. And it looks nice.
The only thing I don't like are the banners that waste precious vertical space when seen on a 14" laptop, but can't blame you for that, given how prevalent it is nowadays.
