Alibaba's UC Browser under govt scanner over data leaks

New Delhi: Alibaba's UC Browser has come under the government's scanner for alleged leak of mobile data of its Indian users and may be banned in the country if found guilty, a senior IT ministry official said on Tuesday.

"There have been complaints against UC Browser that it sends mobile data of its users in India to server in China. There are complaints that even if an user has uninstalled it or cleaned browsing data, the browser retains control of DNS of user's device," the officer who did not wish to be named told PTI.

The officer said if the allegations against the browser are established then it may be banned in the country.

Email sent to UC Web, which operates UC Browser, did not elicit any response.

UC Browser is part of Alibaba's mobile business group. Alibaba has made significant investments in the payment bank firm Paytm and its parent company One97. Besides Paytm, Alibaba has invested in e-commerce firm Snapdeal as well.

UC Browser has last year claimed that it has over 100 million monthly active users in India and Indonesia.

As per Stat-Counter report at the end of June 2017, UC Browser is second most used web browser in India after Google's Chrome and leads mobile phone segment with 48.66 per cent market share.
