The popular UC Browser, owned by China's Alibaba, has mysteriously gone missing from Google Play Store, and nobody seems to know why.

The app, which managed to briefly overtake Chrome to become the most-used mobile web browser in India earlier this year, apparently disappeared from the Play Store on Tuesday, just weeks after topping 500 million downloads on the official Android repository. Developed by UCWeb, US Browser is reportedly the sixth downloaded Android app in India.

It's worth noting here that the iOS version of the app is still available in the Apple App Store while the UC Browser Mini continues to be listed on the Play Store.

While there is no statement from either Google or UCWeb about the unexpected disappearance of the app, some users on Reddit have suggested that the misleading redirect ads served up by UC Web's affiliates to trigger installs likely prompted Google to delist the browser.

An email, recently received by Android Police's Artem Russakovskii from the parent company UC Union, also supports the same theory.

Here's the email:

(iii) require you to CLARIFY the facts for elimination of the negative impact shed upon UC Union; and

(iv) resort to any other legal measures if necessary.

While there is no official confirmation about the ban so far, a Twitter users who claims to work for UC Browser said that the delisting of the app would be in effect for 30 days.

Despite growing popularity in India, UC Browser came under the government radar in August for allegedly leaking sensitive data to China. The app was accused of diverting a massive amount of user search details and sensitive data like IMSI (international mobile subscriber identity), IMEI (international mobile equipment identity) numbers and location information to a remote server in China.
