Google Chrome recently made its built-in tracking and ad-curation platform, Privacy Sandbox, available to a larger audience. Initially rolled out to a small percentage of users, the platform is now accessible to approximately 97% of users, with plans to onboard the remaining 3% in the coming months, according to a blog post by Google.
Privacy Sandbox has faced criticism from privacy experts, but Google has defended its implementation, asserting the need for eliminating third-party cookies and fingerprinting. The platform aims to replace third-party cookies with a more privacy-centric approach to tracking users’ topics of interest. However, concerns have been raised about transparency and data collection in this new system.
A significant majority of websites, around 80%, rely on Google’s Adsense service to generate ads on their pages, as reported by business analytics platform 6sense. Adsense embeds cookies in users’ browsers to effectively target ads based on their behavior as they navigate from site to site. These cookies, known as third-party cookies since they are produced by Google, track users’ actions and help determine their potential interest in purchasing products.
The use of third-party cookies has drawn criticism from privacy advocates, leading some users to seek ways to block them. Browsers like Apple’s Safari, Mozilla’s Firefox, and Brave’s Brave browser have implemented default blocks on third-party cookies. Chrome users also have the option to block these cookies through the browser’s settings menu.

In a blog post from January 2020, Google argued that blocking third-party cookies by default could have unintended consequences that negatively impact both users and the web ecosystem. The company expressed concern about the rise of alternative invasive techniques like fingerprinting, which could compromise user privacy and control.
Google’s recent announcement echoes its previous stance, highlighting the importance of viable privacy-preserving alternatives to third-party cookies, such as the Privacy Sandbox. The company maintains that without such alternatives, there is a risk of limiting access to information for users while potentially encouraging invasive practices.
Privacy Sandbox, Google Chrome’s new platform, allows user data to be tracked within the browser itself, eliminating the reliance on third-party cookies. Google believes this shift will enhance privacy; however, the default blocking of third-party cookies will be implemented at a later stage.
However, the Electronic Frontier Foundation (EFF), a digital privacy advocacy group, criticized an earlier version of the Privacy Sandbox. The group argued that the earlier iteration still tracked users’ behavior, albeit within the browser, and could even be more invasive in certain aspects compared to third-party cookies.
Within the new Chrome interface, users have the option to turn off Privacy Sandbox using the three different settings available in the “Ad privacy” menu. This gives users more control over their privacy preferences.
The Brave browser also offers a similar solution called “Brave Ads,” which tracks users’ behavior. However, this feature is turned off by default, and users have the choice to opt in. Additionally, Brave rewards users in Basic Attention Token (BAT) for viewing ads.
In conclusion, Google Chrome’s Privacy Sandbox has reached a wider audience, promising a more privacy-centric approach to tracking users’ topics of interest. The platform aims to replace third-party cookies while addressing concerns about user privacy and control. Privacy advocates and critics have raised concerns about transparency and potential invasiveness. As the industry continues to evolve, it is essential to strike a balance between ad targeting and user privacy to ensure a positive browsing experience for everyone.
