Apple Previews New Privacy-Focused Ad Tracking Solution Coming to Safari Later This Year

Apple today previewed a new Safari feature called Privacy Preserving Ad Click Attribution that it says will allow advertisers to measure the effectiveness of their ad campaigns on the web without compromising user privacy.


In a blog post, WebKit engineer John Wilander explains that ad click attribution has traditionally been done through the use of cookies and so-called "tracking pixels," allowing both the advertiser and the website where the ad was placed to know when someone has clicked on an ad and later purchased something.

Wilander says the traditional method of ad click attribution has no practical limit on data, allowing for full cross-site tracking of users using cookies. "We believe this is privacy invasive and thus we are obliged to prevent such ad click attribution from happening in Safari and WebKit," he wrote.

Thus, Apple has proposed a modern solution that it says doesn't allow for cross-site tracking of users but does provide a means of measuring the effectiveness of online ads. The feature is built into the browser itself and runs on-device, meaning that the browser vendor does not see any of the ad data.

Here is Apple's summary of its privacy considerations for the feature:
  • Only links served on first-party pages should be able to store ad click attribution data.
  • Neither the website where the ad click happens nor the website where the conversion happens should be able to see whether ad click data has been stored, has been matched, or is scheduled for reporting.
  • Ad clicks should only be stored for a limited time, such as a week.
  • The entropy of both ad campaign ID and conversion data needs to be restricted to a point where this data cannot be repurposed for cross-site tracking of users. We propose six bits each for these two pieces of data, or values between 0 and 63.
  • Ad click attribution requests should be delayed randomly between 24 to 48 hours. This makes sure that a conversion that happens shortly after an ad click will not allow for speculative cross-site profiling of the user. The randomness in the delay makes sure the request does not in itself reveal when during the day the conversion happened.
  • The browser should not guarantee any specific order in which multiple ad click attribution requests are sent, since the order itself could be abused to increase the entropy and allow for cross-site tracking of users.
  • The browser should use an ephemeral session aka Private or Incognito Mode to make ad click attribution requests.
  • The browser should not use or accept any credentials such as cookies, client certificates, or Basic Authentication in ad click attribution requests or responses.
  • The browser should offer a way to turn ad click attribution on and off. We intend to have the default setting to be on to encourage websites to move to this technology and abandon general cross-site tracking.
  • The browser should not enable ad click attribution in Private/Incognito Mode.
Privacy Preserving Ad Click Attribution is available as an experimental feature in Safari Technology Preview 82 and later. To turn on the feature, enable the Develop menu and navigate to the Experimental Features submenu.

Apple says the feature will be turned on for web developers later this year. The company has also recommended it as a web standard to the W3C.

Website Demos Safari Browser’s Upcoming Support for Dark Mode CSS in macOS Mojave 10.14.4

In the next official update to macOS Mojave, Apple's Safari browser will support automatic Dark Mode for websites that support it.


Since the release of Safari Technology Preview 68 in October, Apple has been building support for the use of Dark Mode CSS, enabled via its Develop -> Experimental Features menu. The experimental feature has now made its way into the latest macOS Mojave 10.14.4 developer beta.

macOS Mojave enables users to switch between Light and Dark mode via System Preferences -> General. With the latest macOS developer beta installed, websites that support the new CSS query will automatically adapt their color scheme to match whichever system-wide option is selected.


As noted by iDownloadblog, developers running the macOS 10.4.4 beta can test out the new feature by visiting software engineer Kevin Chen's website, which already supports the new Safari CSS media query. Everyone else can give it a spin by downloading the latest version of Safari Technology Preview, which can be run alongside vanilla Safari in any version of macOS Mojave.
