The first part of the new section explains that TikTok may collect information about the images and audio that are in users’ content, “such as identifying the objects and scenery that appear, the existence and location within an image of face and body features and attributes, the nature of the audio, and the text of the words spoken in your User Content.
While that may sound creepy, other social networks do object recognition on images you upload to power accessibility features (like describing what’s in an Instagram photo, for example), as well as for ad targeting purposes. Identifying where a person and the scenery is can help with AR effects, while converting spoken words to text helps with features like TikTok’s automatic captions.”
The biggest concern is that TikTok doesnt explain how it will use biometric data. “We may collect biometric identifiers and biometric information as defined under US laws, such as faceprints and voiceprints, from your User Content.” The policy further states that the app will ask required permission from users for data collection in accordance with US laws.
