**The goals of the Privacy Sandbox**
------------------------------------
The Privacy Sandbox is currently in development. It aims to:
*
**Build new technology to keep your information private**
People should be able to enjoy their browsing and app experience without worrying about what personal information is collected, and by whom. The Privacy Sandbox technologies aim to make current tracking mechanisms obsolete, and block covert tracking techniques, like fingerprinting. Fingerprinting Information collected about a person’s software and hardware for the purpose of identification.
*
**Enable publishers and developers to keep online content free**
Billions of people around the world rely on access to information on sites and apps. To provide this free resource without relying on intrusive tracking, publishers and developers need privacy-preserving alternatives for their key business needs, including serving relevant content and ads.
*
**Collaborate with the industry to build new internet privacy standards**
The internet is a source of information and engine of economic growth worldwide. Google invites members of the industry – including publishers, developers, advertisers, and more – to get involved and contribute to the development of better privacy standards for the Web and on Android.
**Privacy Sandbox for the Web**
-------------------------------
Privacy Sandbox for the Web aims to reduce cross-site tracking while helping to keep online content and services free for all. By creating new [web standards](https://www.w3.org/standards/), it will provide publishers with safer alternatives to existing technology, so they can continue building digital businesses while your data stays private.

**Frequently Asked Questions**
------------------------------
**What is the Privacy Sandbox?**
--------------------------------
The Privacy Sandbox is an industry-wide effort to develop new technology that will improve people’s privacy across the Web and apps on Android. The proposed solutions will limit tracking of individuals and provide safer alternatives to existing technology on these platforms while keeping them open and accessible to everyone.
**How does the Privacy Sandbox work?**
--------------------------------------
The Privacy Sandbox technologies are currently in development. You can learn more about the proposals on [](https://developer.chrome.com/)[Google for Developers](https://developers.google.com/privacy-sandbox/). Google welcomes members across the industry to [provide feedback or start testing](https://developer.chrome.com/blog/privacy-sandbox-participate/). This site will also be updated monthly as the initiative progresses.
**Why is Google proposing this?**
---------------------------------
New web and app technologies are needed to improve people's privacy online. In recent years, some browsers and platforms have taken steps to restrict or remove existing mechanisms, such as third-party cookies, without effective alternatives in place. This can negatively impact critical ecosystem functionality and put user privacy at greater risk, by leading to adoption of covert tracking.
We believe that developers and businesses should be able to make money from their sites and apps, as well as reach customers with relevant ads. The Privacy Sandbox initiative is developing new solutions that support key ecosystem needs -- without reliance on online tracking identifiers -- so that publishers and developers can provide free content and grow their business in a privacy-preserving way.
**How can I get involved?**
---------------------------
Google invites members from the industry—web browsers, online publishers, ad tech companies, advertisers, and developers—to participate in the development and testing of the proposed new technologies.
For the open web, you can contribute to the public discussions in forums such as the [W3C](https://www.w3.org/), and if you’re a business, talk to your trade groups and technology vendors about engaging in this process. If you’re a developer, we invite you [to join the origin trials](https://developers.google.com/privacy-sandbox/blog/privacy-sandbox-unified-origin-trial).
For Android, feedback on the design proposals can be given via the [Google for Developers](https://developers.google.com/privacy-sandbox/relevance/setup/android) site. This is also where you can sign up for regular updates as the project progresses.
**When will the new technologies launch?**
------------------------------------------
You can expect to hear more about the progress being made with the Privacy Sandbox regularly, including more opportunities for you to test these new technologies on your sites and in your campaigns. For the latest news, follow our [News & Updates](https://privacysandbox.com/intl/en_us/news/) and the blog on [Google for Developers](https://developers.google.com/privacy-sandbox/blog).
