Third Parties

If you have identified yourself as a Third Party, it means that you engage in online interest-based advertising (IBA) on a First Party’s website. This guidance for Third Parties is directed primarily to advertising networks and data companies that collect web-viewing or app data across multiple sites and/or apps and use such data to serve online interest-based advertising.

An advertiser (i.e. a company whose product or service is being promoted in an advertisement) may also be a Third Party, if it engages in data collection and use for online interest-based advertising. However, if the advertiser uses an ad network/exchange/DSP or other entity to collect data for IBA purposes, and that entity does NOT provide such data to the advertiser for its independent use, the advertiser is not a Third Party and not subject to the principles in that capacity.

Third Parties shall provide notice on their websites describing their IBA data collection, use, and disclosure practices. Such notice shall include clear descriptions of the following:

  • The types of data collected online for IBA purposes, including any personal information;

  • The uses of such data, including whether the data will be transferred or disclosed to another entity for IBA purposes;

  • An easy to use mechanism for exercising choice with respect to the collection and use of the data for IBA purposes, or disclosure of such data to another entity for such purposes; and

  • The fact that the company adheres to the DAAC principles.


Below is a more detailed explanation of each of the requirements for Third Parties.
