New academic research published last month looked at the phone-home features of six of today's most popular browsers and found that the Brave browser sent the smallest amount of data about its users back to the browser maker's servers.
The research, conducted by Douglas J. Leith, a professor at Trinity College at the University of Dublin, looked at Google Chrome, Mozilla Firefox, Apple Safari, Brave, Microsoft Edge (the new Chromium-based version), and the Yandex Browser.
Prof. Leith used a series of automated tests to measure and collect the network communications that a browser initiates to its backend infrastructure. These network communications are also known as telemetry or phoning-home.
The tests involved collecting data during several stages of normal browser use, such as:
* On the first startup after a fresh install
* On browser close and restart
* When pasting a URL into the top bar
* After typing a URL into the top bar
* When the browser was sitting idle

The new Microsoft Edge and the Yandex Browser deemed the most data greedy.
