In the update, made on June 2, Tik Tok wrote that the company had added more details on the information they collect "and how it's used, including clarifications related to, for example, collection of user content information, use of data for verification, ad related choices, data sharing with third party services, and data storage/processing practices."
Under the "Image and Audio Information" section, which according to TechCrunch is a newly added section, TikTok wrote, "We may collect biometric identifiers and biometric information as defined under US laws, such as faceprints and voiceprints, from your User Content."
Multiple tech-focused outlets including TechCrunch and The Verge were unable to get clarification on what types of data the updated terms are referring to and why the app would even need to collect this type of data. The amount of data TikTok collects from users was already seen as pretty extensive, but this new update has seemed to set off some new alarm bells for privacy advocates.
TechCrunch noted that there are just a few U.S. states which offer legal protections for tech features like this, including California, Illinois and Texas. There is also the argument that if users agree to the company's terms of service, that is the consent that the company needs to protect itself.
