TikTok changes its privacy policy so it can collect biometric information like 'faceprints' as people use it

TikTok says it could collect "faceprints and voiceprints" on its users – though has not made clear what they are. The new data collection is part of an update to the app's US terms and conditions, which broaden the kinds and amount of information that the app can gather from its users. The terms make clear that all sorts of information might be collected when people use the app, from details about where they are, to their phone, to how they actually use TikTok itself. But perhaps the most unusual of the new additions come as part of an update section on the "Image and Audio Information" that TikTok says it can automatically gather while people use the app. That section starts by noting that the app will collect information about what appears in people's posts.
