Privacy Sandbox

Oct 22, 2025

Google's Privacy Sandbox is an initiative aimed at changing how advertisers track your activity across the web. It seeks to enhance user privacy online while still enabling companies to reach their audiences with relevant ads.

 

What is Privacy Sandbox?

The Privacy Sandbox is a Google-led project designed to create a more private online experience. These cookies are small files that websites use to track your browsing activity across different sites to build a profile for targeted advertising.

Instead of individual tracking, the Privacy Sandbox proposes new technologies that group people with similar interests together, keeping individual identities more private.

The overall aim is to find a middle ground where users have more privacy, and advertisers can still show relevant ads to support their businesses.

 

Key Features of Privacy Sandbox

The Privacy Sandbox introduces several new technologies to achieve its privacy goals. Here are some of the key features:

  • Topics API: This feature observes the topics of websites you've recently visited to identify your general interests. Your browser will then share these broad topics, like "fitness" or "travel," with websites to show you relevant ads.
  • Protected Audience API : This allows advertisers to re-engage with users who have previously visited their website, a practice known as remarketing. However, it's designed to do so in a privacy-preserving way, and it's without sharing your personal data with advertisers.
  • Private Aggregation API: This allows for the creation of summary reports of ad campaign data without revealing individual user information.

 

Use Cases of Privacy Sandbox

The technologies within the Privacy Sandbox are designed to support various online advertising practices in a more private way. Here are some common use cases:

  • Interest-Based Advertising: The Topics API allows advertisers to show ads based on a user's general interests without tracking their every move online.
  • Conversion Measurement: The Attribution Reporting API helps advertisers understand which of their ads are leading to sales or sign-ups. This allows them to see which campaigns are most effective without tracking individual users across sites.
  • Fraud Prevention: Technologies help distinguish between real users and bots, which is crucial for preventing ad fraud, without resorting to individual tracking.

 

FAQ

  1. How does a Privacy Sandbox work?
    The Privacy Sandbox works by moving much of the data processing for advertising from advertisers' servers to your own device and browser. The browser itself will note your general interests based on your recent browsing history. It then shares these broad topics with websites, allowing them to show you relevant ads without knowing exactly who you are.

  2. How do I turn off Privacy Sandbox?
    You can manage the Privacy Sandbox settings within the Google Chrome browser. To turn it off, go to Chrome's "Settings," then navigate to "Privacy and security," and select "Ad privacy." Here, you will find options to disable the different components of the Privacy Sandbox, such as "Ad topics," "Site-suggested ads," and "Ad measurement." You can turn each of these off individually.

  3. Should the Privacy Sandbox be on or off?
    It is a personal choice. Proponents argue that it is a step up in privacy compared to third-party cookies because it limits the sharing of your specific browsing data with numerous companies.
    However, some privacy advocates argue that it still allows for a form of tracking, just managed by Google.
