The arrangement, outlined by the White House official in a statement Monday, seeks to ensure that the American buyers control TikTok’s recommendation software in the US following a divestiture by its Chinese parent, ByteDance Ltd. Owners of the US-based TikTok would lease a copy of the algorithm from ByteDance that Oracle would then retrain “from the ground up,” according to the official. Data from US users would be stored in a secure cloud managed by Oracle with controls established to keep out foreign adversaries, including China, the official said.
