Apple’s Mail Privateness Safety characteristic does not work on the Apple Watch, it’s alleged, as whereas the tracking-prevention system works fantastic in iOS 15, it does not appear to perform inside watchOS.

Outlined throughout WWDC 2021 and launched in iOS 15, Mail Privateness Safety helps forestall an e-mail sender from gaining any details about a recipient’s exercise throughout the Mail app, reminiscent of when an e-mail is opened. Whereas the system works as anticipated for iPhone customers, the identical can’t be stated in regards to the Apple Watch.

In keeping with safety researcher Tommy Mysk on Twitter, the Mail Privateness Safety options do not apply to the Mail app throughout the Apple Watch. In a take a look at, it was proven that each the Mail app itself and the notification preview on the Apple Watch downloads distant content material included in an e-mail utilizing the machine’s IP handle, permitting for monitoring to happen.

It seems that Mail Privateness Safety solely applies to the iOS model of the Mail app, and never the Apple Watch.
