Safari and WebKit block services that turn emails into tracking IDs
Original title: Safari blocks trackers that turn your email into a tracking ID
The blocks ship in iOS 27, iPadOS 27, macOS 27, and visionOS 27 and stop pages from sending addresses to identity-resolution servers.
Apple’s Safari and WebKit now block connections to identity-resolution services that convert email addresses into persistent tracking identifiers. Those services collect an address at login or newsletter signup, store a linked ID, and can keep it after logout. Blocking is applied by domain so providers cannot evade it by changing request structure, while first-party personalization is meant to remain.
- Logging out or unsubscribing does not remove the stored identifier or email.
- Identity graphs can include names, phones, addresses, IPs, accounts, and cookies.
- Hide My Email in iCloud+ can issue unique addresses per site.
- WebKit says the change follows browsers blocking cross-site cookies.
- 1.Use Hide My Email or similar unique addresses to limit email-based tracking.
