“Some of your Chrome features and settings will not be available at this time because of iOS constraints,” says Google.

Google clarify that their Chrome browser for iOS now uses the Apple’s new Web rendering engine called WKWebView, and does not support Do Not Track setting.

It is fascinating to note that Safari uses WKWebView, and rendering engine allows Safari turn on the Do Not Track but limits same functionality on other browsers.

Arvind Narayanan, assistant professor of the computer science at Princeton, worked on developing the ‘Do Not Track’ special feature. He pronounces that Apple is to be blamed for the absence of this feature on other browsers apart from Safari.

“If the API in question doesn’t expose that functionality, there’s nothing Google or Mozilla can do about it,” says Narayanan.
