The app’s availability in the U.S. has been thrown into jeopardy over data privacy and national security concerns.

Apple and Google restored TikTok to their app stores on Thursday after the popular social media app went dark last month.

The law requires TikTok's Chinese parent company, ByteDance, to sell its U.S. assets in order to continue operating in the U.S. While the law only mandated that ByteDance remove TikTok from app stores in the U.S. if it failed to meet the sale deadline, company executives decided to shut down the app entirely.
