I'm happy to answer that question.
It is true that we do not collect precise location information about our users. We do collect approximate location, often based on the user's IP address. What we can do is identify that someone may be in a particular province or city, but we wouldn't be able to identify, with any precision, where an individual was located. We wouldn't be able, for example, to deliver a pizza to somebody's house based on the location information we have.
The part of our privacy policy that I believe you are alluding to discusses how data may be shared from advertising partners that we work with. Sometimes advertisers launch campaigns with TikTok, and they want to understand, for example, when a user has clicked on an advertisement, if they've put something into a shopping cart, or if they've downloaded an app. Oftentimes, mobile identifiers are the ways that we can match up activity between a TikTok user and an action they may have taken on an advertiser's website.
