The TikTok ownership transition provides an interesting comparison of data collection practices between the US and China (or at least this particular ownership group and whatever agreements they had in place to facilitate the sale).

Here are the three biggest changes to TikTok’s privacy policy

Adds Precise Location Tracking

Previously this was just based on SIM card and IP signals, now GPS and location data is folded in.

Now Tracks AI Interactions

This is net new to the privacy policy, so it’s hard to tell what used to happen. Seems similar to most LLMs now.

Expands Its Ads Network

The Meta Audience Network play. TikTok will use the data it collects about you to deliver ads via its Ad Network on other sites and apps.
