How does tiktok "know" my network, if I am always behind VPN and no account? (lemmy.dbzer0.com)

So I decided to use my really old pixel 3a as a test of sorts. It has calyxos, with always on VPN (surfshark). I have no accounts on it, google or anything else. I usually use it for streamio or tiktok.

But I have noticed that I am still getting video recommendations based on what my flatmate watches (we share an internet router). Or what I watch on my other non-VPNed devices.

So what gives?

I am looking for an explanation as to why its happening, not just how to fix it. Btw I also use private DNS so dns leaking is not the likely culprit.

Anyone knows how to debug this info leak?
