UC Browser is a Chinese web browser developed by the China-based mobile Internet company UCWeb, which is owned by the Alibaba Group. This browser is compatible with both Android and iOS. Though it is one of the most downloaded browsers in some countries, it has been declining in popularity as researches have found that UC Browser is insecure, with many vulnerabilities and privacy issues. UC Browser leaks sensitive IMSI, IMEI, MSISDN data, Android ID, MAC address and users Geo-location & Wi-Fi-related data without any encryption. These leaks are used by intelligence agencies to track users. Hence we recommend you to use alternatives like Google Chrome, Firefox and Jio Browser that can serve you better, unlike UCBrowser.
