TikTok is again available on the US app stores of Apple and Google, after President Donald Trump postponed enforcement of a ban of the Chinese-owned social media platform until 5 April.

The popular app, which is used by more than 170 million American users, went dark briefly last month in the US as the ban deadline approached.

Trump then signed an executive order granting TikTok a 75-day extension to comply with a law banning the app if it is not sold.

TikTok did not immediately respond to a request for comment from BBC News.

According to Bloomberg, which first reported TikTok's return to app stores in the US, the decision to resume its availability came after Apple and Google received assurances from the Trump administration that they would not be held liable for allowing downloads, and the ban wouldn't be enforced yet.

The ban, which passed with a bipartisan vote in Congress, was signed into law by former President Joe Biden. It ordered TikTok's Chinese owner ByteDance to sell the US version of the platform to a neutral party to avert an outright ban.

The Biden administration had argued that TikTok could be used by China as a tool for spying and political manipulation.

China and TikTok have repeatedly denied those accusations. Beijing has also previously rejected calls for a sale of TikTok's US operations.

The law banning the app was supported by US lawmakers on both sides of the aisle and it was ultimately upheld by the Supreme Court.

Trump himself had supported banning the app during his first term in office but he appeared to have a change of heart last year during the presidential race.

He professed a "warm spot" for the app, touting the billions of views he says his videos attracted on the platform during last year's presidential campaign.

When the app started working again in the US last month, a popup message was sent to its millions of users that thanked Trump by name.

TikTok chief executive Shou Chew met Trump in Mar-a-Lago after his electoral victory in November and later attended his inauguration ceremony.

Trump has said he wants to find a compromise with the Chinese company that complies with the spirit rather than the letter of law, even floating an idea of TikTok being jointly owned.

"What I'm thinking of saying to someone is buy it and give half to the US, half, and we'll give you a permit," he said recently during a news conference about artificial intelligence.

And he also said he would be open to selling the app to Oracle co-founder Larry Ellison, as well as billionaire Elon Musk, who leads the Trump administration's Department of Government Efficiency.

Previous names linked with buying TikTok include billionaire Frank McCourt and Canadian businessman Kevin O'Leary - a celebrity investor on Shark Tank, the US version of Dragon's Den.

The biggest YouTuber in the world Jimmy Donaldson - AKA MrBeast - has also claimed he is in the running after a number of investors contacted him after he posted on social media that he was interested.
