 **Sponsor**: Epsilon
 
 **Background**:  
-Google recently published [an update](https://developer.chrome.com/docs/privacy-sandbox/chrome-testing/) regarding the UK CMA-aligned Chrome cookie deprecation testing labels announced in May. Chrome intends to label 9.5% percent of Chrome Stable browsers globally. A browser instance, if labeled, is either Mode A (8.5%, opt-in testing beginning Q4 2023) or Mode B (1%, forced cookie deprecation beginning Q1 2024). Two means are offered to access the label. One can read a request header after setting a special partitioned (CHIPS) cookie or client-side via a new `Navigator` script API promise.

 **Notes**  
-No requirement to communicate label provenance, header versus API access.
-
 Privacy Sandbox enrollment is _not_ required to access the labels.  
 
-If you have opinions or feedback about the test group labeling plans, the Chrome team has encouraged interested parties to weigh in on the Privacy Sandbox Developer Support “chrome-testing” issues. Link below.
