The social media platform formerly known as Twitter can now harvest your biometric data and DNA. A new update quietly added to the platform's privacy policy says that X now has permission to harvest its users' fingerprints, retinal scans, voice and face recognition and keystroke patterns. The update would mean that anyone who uses fingerprint verification to log in to the app from their phone, posts selfies or videos to the platform or speaks their mind on X'spaces' could see their unique biometric data catalogued by the company. The new policy, which describes its interest in users' biometrics as'for safety, security, and identification purposes,' also added the platform's intent to scrape up data on users' job history, educational background and'job search activity.' The move follows nearly a year of turmoil for the microblogging app, which has included Musk requesting that its users pay subscription fees for premium services and verification: part of his larger plan to recover from cratering advertising revenue.

Recently, TikTok made a change to its U.S. privacy policy, allowing the company to "automatically" collect new types of biometric data, including what it describes as "faceprints" and "voiceprints." TikTok's unclear intent, the permanence of the biometric data and potential future uses for it have caused concern among experts who say users' security and privacy could be at risk. On June 2, TikTok updated the "Information we collect automatically" portion of its privacy policy to include a new section called "Image and Audio Information," giving itself permission to gather certain physical and behavioral characteristics from its users' content. The increasingly popular video sharing app may now collect biometric information such as "faceprints and voiceprints," but the update doesn't define these terms or what the company plans to do with the data. "Generally speaking, these policy changes are very concerning," Douglas Cuthbertson, a partner in Lieff Cabraser's Privacy & Cybersecurity practice group, tells TIME.

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.

TikTok quietly changed its US privacy policy this week to notify users it may start collecting'faceprint and voiceprint' and other biometric data. The app did not specify what the data would be used for but said it would ask for permission first, 'where required by law.' The update comes just three months after TikTok paid more than $90 million to settle a class-action lawsuit claiming it secretly recorded millions of members' facial features and other biomarkers. TikTok reportedly has 100 million users in the US alone. TikTok has updated its privacy policy to notify US users it may record the'faceprint and voiceprint' and other unique biometric data.
