Privacy Sandbox
01 Definition
Privacy Sandbox meaning: Google's set of proposed web technologies for advertising that reduce cross-site tracking.
Privacy Sandbox is a Google initiative offering browser-based APIs meant to support interest targeting, remarketing, and measurement without third-party cookies or individual cross-site identifiers. It is Google's proposal, not an industry standard, and its features and timeline have changed over time. Advertisers should treat it as one option among several.
Why it matters
How Privacy Sandbox fits the work
Because it comes from the owner of the Chrome browser, Privacy Sandbox could shape how a large share of web advertising works, so advertisers watch its direction closely.
In context
The ad tech team tested a Privacy Sandbox measurement API to see whether it could report conversions without the third-party cookies Chrome was phasing back.
Practical note
Privacy Sandbox is controlled by Google and has shifted in scope and schedule, so plan for multiple cookieless approaches rather than depending on it alone.
