 ## 4. Legal Effects
 
-The specification is designed to express a generic preference to have their data not shared or sold, or used across different contexts for targeted advertising. The spec discusses a number of laws and regulations that may be implicated by declaring such a preference, though legal effects will ultimately be determined by local regulators. This list is intended to provide examples, not be complete. Website operators may also choose to respect GPC beyond the legal requirements.
+Where laws arise to provide Internet privacy GPC intends to have a very specific privacy purpose. **It asks domains not to share or sell people’s personal data, or to use personal data across different contexts, using similar definitions to CCPA and other U.S. state privacy laws.** Other nationalities or regions may choose to incorporate the signal directly or may find user-agents using it. While the legal or regulatory requirements to respect GPC vary, people’s intent in exactly what they are requesting should be considered consistently.
 
-There are situations where the design of GPC, by intent, matches specific legal or regulatory mechanisms. The intent is to connect GPC to specific laws and legally-understood requests by users to allow users to exercise privacy rights at scale.
+GPC is not necessarily intended to invoke every new privacy right in every jurisdiction. For example, GPC is not intended to globally invoke data deletion rights on every website people visit. GPC is also not intended to limit a first party’s use of personal information within the first-party context (such as a publisher targeting ads to an individual on its website based on that individual’s previous activity on that same site). For that reason, GPC should not be interpreted as exercising the CCPA’s right to limit the use of sensitive information in a first-party context.
 
 ### 4.1 GPC in the US
 
-Since 2018, at least nineteen states have passed comprehensive state privacy laws that include, among other rights, the right to opt out of the sale or sharing of personal information and/or the right to opt out of cross-context targeted advertising. Many of these laws explicitly state that consumers may exercise these rights through a universal signal, including a signal sent through a browser or operating system. At least two laws — those of California and Colorado — state that receipt of a Global Privacy Control signal is to be interpreted as a legally binding exercise of the opt-out right in that state.

 ## 6. User Experience Considerations and Recommendations
 
-It is not considered standard for W3C specifications to present user interface recommendations or restrictions. User interfaces are the domain of user-agents who, being closest to the user, best understand how their users interpret and react to the underlying functionality. For GPC, some user-agents may present themselves as privacy-focused technology, in which case it may make sense for the signal to be defaulted to on at all times, which, for example, is supported in California and Colorado for privacy-focused technology. Some user-agents may be generic, with no expectation for people setting defaults. Some user-agents may present GPC in different formats and devices and necessitate unique user interface requirements.
