ByteDance is facing a class-action lawsuit over claims that its CapCut video-editing app is vacuuming up data from its more than 200 million active users without consent. Among other things, the lawsuit, which was filed in Illinois, claims that CapCut violates the state's Biometric Information Privacy Act (BIPA) by collecting data like face scans and voiceprints without informing users or getting express permission.

The app also allegedly collects details about a user's location, date of birth and gender as well as their photos and videos. Much of this is said to be in service of delivering targeted ads. In addition, the suit claims that the app is capable of harvesting data from user devices, including the MAC address and SIM serial number.
