&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;A worklet is a self-contained logic processing service that executes within Chrome browsers. Each worklet is associated with a single domain, and runs code written by either a buyer or a seller.&amp;lt;ref&amp;gt;https://github.com/WICG/turtledove/blob/master/FLEDGE.md&amp;lt;/ref&amp;gt; &lt;br /&gt;
&lt;br /&gt;
== Loading logic into the browser ==&lt;br /&gt;
Buyers and sellers post their desired logic to a well-known URL from which the browser will fetch the logic and potentially implement. &lt;br /&gt;
&lt;br /&gt;
Google has not yet specified whether the well-known location will be a Google-controlled server or a URL controlled by the buyer or seller. &lt;br /&gt;
&lt;br /&gt;
Google has not yet specified how buyers or sellers would receive feedback on the following:&lt;br /&gt;
&lt;br /&gt;
# Whether Google approved their logic for application in a Chrome browser worklet (useful for QA)&lt;br /&gt;
&lt;br /&gt;
# How many browsers have applied this logic (useful for QA)&lt;br /&gt;
&lt;br /&gt;
# How many browsers qualify for each output of this logic (useful for planning)&lt;br /&gt;
&lt;br /&gt;
== Restricted functions ==&lt;br /&gt;
To prevent buyers or sellers from combining information outside of Google's control, the code in the worklets cannot access or communicate with the publisher page or the network. &lt;br /&gt;
