More on AddThis — looking at the GSA contract

August 31, 2009

A quick follow up on last week’s post outlining questions about the privacy practices of AddThis when installed on government websites. As a result of a FOIA request by the Electronic Privacy Information Center, the General Services Administration has now released its contract with AddThis. As EPIC points out, this contract is one of the few disclosed contracts to provide that persistent cookies will not be used on .gov sites.

(Note: Clearspring is the parent company of AddThis and the formal party to the GSA contract.)

Hopefully AddThis will move quickly to resolve this issue and also to shore up their relatively weak privacy disclosures and opt-out processes.

    As you noted, our agreement with the GSA specifically specifies that we don’t serve up persistent cookies on Web sites with a .gov top level domain. We do comply with the agreement.

    We’ve tested and were not able to reproduce having the site’s AddThis installation serve up a flash cookie. Did you clear out your flash cookies before visiting to rule out the flash cookie coming from a non .gov Web site?

    If we’re missing something, please send us a way to reproduce the results that had. We’d appreciate the help.

    Feel free to contact me personally if you have any questions. We’re happy to help. –

      Hi Justin,

      Thanks for the prompt attention to this. I just went through the process again two times, first clearing all flash cookies (once with the BetterPrivacy add-on and then separately through the control panel on the Adobe site), and then clicking on the widget on the top page of Both times new Flash cookies are written immediately when I click on widget. Happy to continue to test this as you debug it, just let me know.

      Also, any thoughts on the other questions posed in the earlier post?
