TikTok said it will have to “go dark” this weekend unless the outgoing Biden administration assures the company it won’t enforce a shutdown of the popular app after the Supreme Court on Friday unanimously upheld the federal law banning the app unless it’s sold by its China-based parent company.

The Chinese-owned company said it would cut off its services unless the U.S. assures Apple, Google and other companies that they would not be punished for hosting and distributing TikTok.

TikTok says it plans to go offline on Sunday, January 19th if the Biden administration doesn’t intervene. The company confirms earlier reporting that it will be “forced to go dark” on the 19th unless the outgoing administration provides a “definitive statement” assuring its “most critical service providers” that they won’t be held liable for breaking the law.
