P3P

<p>The Platform for Privacy Preferences Project (P3P) is an obsolete <a href="/facts/Protocol_(computing)/5uady7cB">protocol</a> allowing <a href="/facts/Website/SAsjJnca">websites</a> to declare their intended use of information they collect about <a href="/facts/Web_browser/2pfyymLs">web browser</a> users. Designed to give users more control of their <a href="/facts/Personal_information/384PbBg5">personal information</a> when browsing, P3P was developed by the <a href="/facts/World_Wide_Web_Consortium/lGWmhF6M">World Wide Web Consortium</a> (W3C) and officially recommended on April 16, 2002.  Development ceased shortly thereafter and there have been very few implementations of P3P. <a href="/facts/Internet_Explorer/uL8a4Y5l">Internet Explorer</a> and <a href="/facts/Microsoft_Edge_Legacy/fmuGF7t0">Microsoft Edge Legacy</a> were the only major browsers to support P3P. <a href="/facts/Microsoft/nGIDDXdx">Microsoft</a> has ended support from <a href="/facts/Windows_10/be9IHehJ">Windows 10</a> onwards. Internet Explorer and Edge [Legacy] on Windows 10 no longer support P3P as of 2016. W3C officially obsoleted P3P on 2018-08-30. The president of <a href="/facts/TRUSTe/7UoLNE4E">TRUSTe</a> has stated that P3P has not been implemented widely due to the difficulty and lack of value.
