TikTok is the most downloaded app in the world. Known for short viral videos, it has tens of millions of users in the U.S. In order to operate successfully, TikTok collects a lot of data. It tracks account information, search history, and any content created through the platform, along with users’ locations and behavioral information. Companies like Facebook and Google collect similar data, but there’s one major difference: TikTok is based in China.
