Chrome has begun to roll out the various Privacy Sandbox APIs. Starting this week users will begin to see prompts about this new feature on browser startup, after upgrading to Chrome v115.
Chrome Privacy Sandbox Prompt
This prompt is a Opt-Out style prompt, selecting ‘Got It‘ will automatically enable the various APIs bundled in this update. To be clear, these APIs are alternative ways to track you, albeit slightly less intrusive than the 3rd party cookies they are seeking to replace.
It should be noted that several of these APIs have failed to achieve W3C Standard status, and have documented disapproval by other browser developers. Both the Webkit (Apple) and Mozilla (Firefox) teams have stated they have no intention of adding support for the Topics API for example. Google faces an uphill battle when it comes to achieving buy in.
