TikTok said on Friday it is moving U.S. users’ data to Oracle servers stored in the United States. Overshadowing its migration announcement was a damning report that followed, claiming that TikTok staff in China had access to its U.S. users’ data as recently as this January.

The report from BuzzFeed News, which cites recordings from 80 TikTok internal meetings it obtained, claims that U.S. employees of TikTok repeatedly consulted with their colleagues in China to understand how U.S. user data flowed because they did not have the “permission or knowledge of how to access the data on their own.”
