What portion of my browsing history gets transmitted as part of these extensions?

We record your visits to approximately 10,000 news sites and political blogs. Our records are not associated with your name or other personally identifiable information, but with a unique ID assigned to your extension. We do not record visits to social network sites or search engines.

You can access the full list of URLs we track. Note that not all are used to produce your balance score.

How can I end my participation in this study?

You may end your participation at any time by right-clicking (or, on OS X, control-clicking) on the extension's icon, selecting "manage extensions," and then clicking the trash can icon next to the extension's name to delete it.

How can I contact you?

If you have questions, you can email us at balanceteam@umich.edu.
