Hi Justin,


So we are already OK, I missed that.


The proposal then becomes simply:



If a third party receives a DNT: 1 signal then:


1. the third party MUST NOT collect, retain, share, or use data related to
the network interaction as part of which it received the DNT: 1 signal;


2. the third party MUST NOT use data about the user gathered in another
context, including when it was a first party.


I would also add the new sentence about unique identifiers, along with the
proposal for limiting their duration if for a permitted use, but maybe that
will need its own CfO? 


3. the third party MUST NOT store in the user-agent, or derive from data
already stored, any unique identifiers.
