In a recent report Forbes says Xiaomi's Mint Browser collects more user data than necessary, but the company denies any violations.
Most of the information collected is similar to that transmitted by most other websites and mobile applications.
This is such data as the device name and OS version, but the browser also sent the search engine settings and the entire search history to Xiaomi servers. Even incognito queries.
Yesterday, the Mint Browser developers released update, but according to researchers, the application still sends the same analytical data.
If you're looking for a mobile web browser that respects your privacy, you're probably better off using Firefox or DuckDuckGo Browser.
