You'll never guess which mobile browser is the worst for data collection. We were shocked – SHOCKED – by the answer. Mirror, mirror on the wall, who is the slurpiest mobile browser of them all? The answer, according to VPN vendor Surfshark, is Chrome. Surfshark's research focused on the top ten browsers based on AppMagic rankings. This included Safari due to it being the default browser on iPhones. Between them, Chrome and Safari account for almost 90 percent of the mobile browser market, according to Statcounter, while also being among the top for data collection. At first glance, it doesn't look good for Chrome. According to Surfshark, the browser collects 20 different data types, including contact info, financial details, location, browsing history, search history, user content, identifiers, usage data, and diagnostics. Surfshark noted that it was the only app that collected financial details, although it also pointed out that users might choose to allow the browser to save the data for convenience. It is also worth considering that much of the data captured by Chrome is by Google's services, such as Search and Maps. Second place was the Bing app, which collects 12 data types, followed by Pi Browser (nine types), and Safari and Firefox (eight types each). The data types are important. For example, while Safari, Chrome, Opera, and Bing all collect the user's location, only Bing collects their precise location data. Bing, Opera, and Pi Browser also collect data for third-party advertising, whether for showing ads in the app or sharing the data. Edge, Bing, and Pi Browser also collect data that could be used to track users. Such data could potentially be sold to data brokers or used for targeted advertisements. The slurping habits of mobile browsers are not secret; Surfshark analyzed the privacy details of these apps on the Apple App Store. However, the findings highlight the amount of data collected by mobile browsers and what a seemingly innocent sign-in to get access to other services might do. Surfshark noted that the most commonly used browsers tended to be the ones that collect the most data, while others with lower usage, such as Brave and Tor, collect the least. "Brave collects a limited set of data types, specifically identifiers and usage data. Tor goes even further, standing out as the most privacy-centric browser by collecting no data at all," Surfshark said.
Daily Brief Summary
Surfshark's study reveals Google Chrome as the top data-collecting mobile browser, capturing 20 different types of user data including financial and location information.
Safari, Chrome's closest competitor in terms of market share, also ranks high in data collection but includes fewer types than Chrome.
The research highlights Bing app as another major collector, pulling 12 data types, while Safari and Firefox each collect 8 types.
Specific data collections such as precise location tracking were unique to certain browsers like Bing, which also shares data for third-party advertising.
Less popular browsers like Brave and Tor show significantly lower data collection, promoting user privacy with minimal data retrieval.
The findings underscore the privacy implications of using dominant browsers and how they might use the significant data they collect, potentially for targeted advertising or selling to data brokers.
Surfshark analyzed the privacy policies of these browsers as listed on the Apple App Store to compile their report.
