TikTok will use only U.S. user data for its U.S. algorithm to address security concerns.

TikTok is set to retrain its U.S. algorithm using only American user data under a new agreement, according to reports. The change aims to address national security concerns by limiting data access to foreign entities. The platform may also launch a separate U.S.-only app, though details remain unclear. The move follows political pressure and potential regulatory action, with experts noting the shift could significantly alter how content is recommended to American users.
