The US government is considering a ban.
This came about after lawmakers in the US voted on a large spending bill that included money for military aid. Hidden within this bill was a rule that could force TikTok to be sold by its Chinese owner, ByteDance.
This move comes from concerns by US officials that TikTok might be a security risk. They worry that the Chinese government could be using the app to collect information from its millions of American users. China denies these claims, and TikTok says a ban would hurt the US economy and free speech.
If the bill becomes law, TikTok would have one year to find a new US owner. If no buyer is found, the app could be removed from app stores, making it much harder for people to download and use.
President Biden is expected to sign the bill into law. This is a big story because it could affect how many people can use TikTok in the future.
