Fun part is its deduction of locale by looking at your number/sim card. I usually get an eSIM while travelling, and the company seems to be based in Netherlands. Was in Mexico last time, and was getting a constant stream of content from Amsterdam. Took me a while to understand why.
Pretty sure it uses regular geo information as well because we travelled to France and immediately saw a bunch of French tiktok even though the SIM card was Canadian.
It's actually a fun quirk, you visit a country and you get to see their tiktok videos.
