The US general manager of TikTok has said the Chinese-owned video-sharing app is “here for the long run”, after President Donald Trump said he would ban it in the US.
Vanessa Pappas told TikTok users in a video statement that its staff were building “the safest app”.
Mr Trump said he could sign an executive order as early as Saturday, amid concerns the app could be used to collect Americans’ personal data.
TikTok denies any Chinese control.
The fast-growing app has up to 80 million active monthly users in the US and the ban would be a major blow for the Chinese firm ByteDance which owns it.
It was not immediately clear what authority Mr Trump has to ban TikTok, how that ban would be enforced and what legal challenges it would face.
But Reuters news agency reported on Saturday that ByteDance had agreed to completely divest TikTok’s US operations. Previously the Chinese company had sought to keep a minority stake, with Microsoft reportedly in talks to buy the app.
The move to ban TikTok comes at a time of heightened tensions between the Trump administration and the Chinese government over a number of issues, including trade disputes and Beijing’s handling of the coronavirus outbreak.
What did Ms Pappas say?
TikTok’s US general manager said the company had heard an “outpouring of support” for the app, and thanked the “millions of Americans” who used it every day.
“We’re not planning on going anywhere,” she said.
Addressing concerns about data security, she said TikTok was behaving responsibly.
“When it comes to safety and security, we’re building the safest app, because we know it’s the right thing to do,” she said.
“We’re here for the long run, continue to share your voice here and let’s stand for TikTok.”
What is TikTok?
The platform has exploded in popularity in recent years, mostly with people under 20.
They use the app to share 15-second videos that often involve lip-synching to songs, comedy routines and unusual editing tricks.
These videos are then made available to both followers and strangers. By default, all accounts are public, although users can restrict uploads to an approved list of contacts.
TikTok also allows private messages to be sent but this facility is limited to “friends”.
The app is reported to have around 800 million active monthly users, most of whom are in the US and India.
India has already blocked TikTok as well as other Chinese apps. Australia, which has already banned Huawei and telecom equipment-maker ZTE, is also considering banning TikTok.
Why Trump dislikes TikTok
Analysis by James Clayton, BBC North America technology correspondent
Trump’s dislike of the app goes further than just privacy concerns.
In India app was banned after a border skirmish with China – it was caught up in a geopolitical feud. And that’s what’s happened here, too. Trump’s sights are set firmly on China – and this should be seen through that lens.
TikTok says that it doesn’t keep any data in China and would never give it to China.
But, in many ways it doesn’t matter what they say, the fact that they are owned by a Chinese’s company is guilt enough.
Not to be overlooked either is Trump’s previous experience with TikTok.
Last month users claimed to have scuppered his Tulsa rally after signing up to tickets they had no intention of using.
And although there are Republican and conservative voices on TikTok, the profile of users in the US is generally young and liberal/left.
It’s hard to believe that’s not a factor here.
Why is the US concerned about TikTok?
US officials and politicians have raised concerns data collected by ByteDance via TikTok may end up being passed to the Chinese government.
TikTok operates a similar but separate version of the app in China, known as Douyin. It says all US user data is stored in the US, with a backup in Singapore.
This week, TikTok told users and regulators it would observe a high level of transparency, including allowing reviews of its algorithms.
“We are not political, we do not accept political advertising and have no agenda – our only objective is to remain a vibrant, dynamic platform for everyone to enjoy,” the CEO, Kevin Mayer, said in a post this week.
“TikTok has become the latest target, but we are not the enemy.”
