Apple has implemented new anti-tracking protections in Safari and WebKit, blocking connections to identity resolution services that convert email addresses into persistent tracking identifiers. This update is included in the latest releases of iOS, iPadOS, macOS, and visionOS. The protections prevent third parties from collecting email addresses entered on websites, which could be used for profiling and ad targeting without user consent. Users often remain unaware that their email addresses can be used for long-term tracking across multiple sites. The new measures aim to enhance user privacy by restricting how personal information can be repurposed for tracking. The protections apply at the domain level, making it difficult for services to bypass them. Apple emphasizes that first-party personalization remains unaffected by these new restrictions. The update reflects Apple's ongoing commitment to user privacy, following previous measures against cookie-based tracking.
