Apple has consistently prioritized user privacy, especially with its Safari browser and iOS operating system. These changes have had significant implications for users, developers, and marketers alike. At Z2A Digital, we’ve closely followed these developments to adapt our strategies accordingly. Here’s a timeline highlighting the key privacy changes in Safari and iOS, presented in an infographic format for clarity and ease of understanding.

  1. June 2017 - Safari Introduces Intelligent Tracking Prevention (ITP) 1.0: Apple announced ITP 1.0 at its Worldwide Developers Conference. This update reduced cross-site tracking by limiting the use of cookies.
  2. September 2018 - ITP 2.0 in Safari: This update further restricted the ability of advertisers to track users across websites. It removed the 24-hour cookie access window and introduced stricter rules against first-party cookies.
  3. March 2019 - ITP 2.1: ITP 2.1 introduced a seven-day cap on script-writable storage, including cookies. This change aimed to limit pervasive user tracking while still allowing websites some level of personalization.
  4. September 2019 - ITP 2.2 and 2.3: These updates further shortened the lifespan of certain cookies and introduced measures to prevent workarounds that were being used to bypass previous ITP rules.
  5. June 2020 - iOS 14 Announcement: At WWDC 2020, Apple announced iOS 14, which included significant privacy updates. The most notable was the requirement for apps to obtain user consent before tracking their activity across other companies' apps and websites.
  6. December 2020 - iOS 14.3 Released: This update introduced App Tracking Transparency (ATT), requiring apps to request permission to track users across apps and websites owned by other companies.
  7. April 2021 - iOS 14.5 Launch: With this launch, the ATT framework became active. Apps now had to show a prompt asking users for permission to track their activities for advertising purposes.
  8. September 2021 - iOS 15 Release: iOS 15 brought more privacy features, including Mail Privacy Protection, which hides users' IP addresses and prevents senders from knowing when an email is opened.
  9. Ongoing - Safari and iOS Privacy Updates: Apple continues to update its privacy policies and features in Safari and iOS, focusing on enhancing user privacy and data security.

These changes by Apple reflect a growing trend towards greater user privacy in the digital world. They have significant implications for how businesses approach mobile marketing, user tracking, and data collection. Adapting to these changes requires a shift towards more privacy-conscious marketing practices, focusing on first-party data and contextual advertising strategies.

For businesses and marketers, staying informed and adapting to these changes is crucial for continued success in the ever-evolving digital landscape. Apple’s commitment to privacy sets a standard that is likely to be followed by other tech giants, signaling a broader shift in the industry towards prioritizing user privacy.
