Re: TPE Public Comment

Ms. Glasser,

Thank you for your comments (last June) on the Tracking Preference Expression Last Call Working Draft.

The decision to define the term tracking was previously resolved by the group; you do not provide new information to justify reopening this long-discussed issue. However, your concern about an exception for first party data is mistaken. The definition of tracking applies to all cross-context data collection and usage, and the group has determined that the use of data previously collected as a first party to target ads in a new context is not consistent with a Do Not Track request. Similarly, collection of data from widgets distributed around the web are defined as cross-context data collection in the specification, and thus are subject to DNT:1 requests.

The requirements on when user agents may send DNT:1 signals on behalf of a user as detailed in Section 4 of the TPE. The group previously rejected providing more detailed requirements; you do not provide new information or a proposal to cause us to reopen this issue. We revisited this issue during the Last Call process in considering a proposal to require information about the DNT setting party within the DNT field, but that proposal was rejected by the group.

Please let us know whether these explanations resolve your concerns.
