Didi is China's most popular ride-hailing app
Didi, a ride-hailing app for China, has been ordered from China's app store. This comes just days after New York was launched by the Chinese tech giant.
China's cyberspace regulator ruled that Didi had broken the laws regarding user data collection and ordered its removal.
Although the firm stated that the app would still be available, it said that it had stopped accepting new users.
China recently took steps to improve governance of its large tech companies.
Didi Chuxing is a similar platform to Uber and Lyft that arranges over 20 million rides daily in China.
It was founded in 2012 and is especially popular in China's most populated cities. It has also expanded to 15 other countries.
It raised $4.4bn in an initial public offering in New York last week, which was the largest share sale since 2014's Chinese online retailer Alibaba.
The shares plunged 5.3% just a day after trading began in New York. This was due to the announcement by the Cyberspace Administration of China, (CAC), that it was looking into the company to safeguard "national security" and the public interest.
Didi collects huge amounts of real-time mobility information every day. Some of this data is used for autonomous driving technologies, traffic analysis, and other purposes.
According to the CAC, "After verification and checks, Didi Chuxing was found in serious violation of regulations regarding its collection and use personal information."
This investigation comes after regulatory crackdowns against other tech companies, such as Alibaba and Meituan's food delivery service.
