It tracks the location of a body (or anything else that causes the same sort if interference), but it doesn't identify the person, and as such they can reasonably make the claim that this technology is privacy preserving.
Of course, as with anything that claims to anonymise data, or preserve privacy, that assertion starts to fall down when you use the resulting data in conjunction with other data sources, even if they too claim to be privacy preserving.
We all know where this is going. Oh well, guess we need Faraday suits now.

Goddamn, every day it's a new nightmare. I just want out. Babies born now will never know what it was like to be a free-ish human.
