Following the change in the policy,  the app can now collect users’ faceprints, voiceprints and biometric data.

Reached for comment, TikTok could not confirm what product developments necessitated the addition of biometric data to its list of disclosures about the information it automatically collects from users, but said it would ask for consent in the case such data collection practices began, reports Tech Crunch.

The biometric data collection details were introduced in the newly added section, “Image and Audio Information,” found under the heading of “Information we collect automatically” in the policy, the news portal reported.

This is the part of TikTok’s Privacy Policy that lists the types of data the app gathers from users, which was already fairly extensive, the news portal said.
