Privacy Bird® and Privacy Finder are tools that help you find out what web sites will do with your information before you provide it. Privacy Bird is a free tool you can add to your Internet Explorer web browser. Privacy Finder is a free online search engine that will help you identify web sites that respect your privacy.

Privacy Bird lets you see what's really going on at Web sites. The bird icon alerts you about Web site privacy policies with a visual symbol and optional sounds.

Privacy Bird reads privacy policies written in the standard format specified by the World Wide Web Consortium's Platform for Privacy Preferences (P3P).

We invite you to download Privacy Bird software for free. This software will help Internet users stay informed about how information they provide to Web sites could be used. Privacy Bird automatically searches for privacy policies at every website you visit. You can tell the software about your privacy concerns, and it will tell you whether each site's policies match your personal privacy preferences. The software displays a green bird icon at Web sites that match, and a red bird icon at sites that do not.

Privacy Bird installs quickly and easily into Microsoft Internet Explorer Web browsers (version 5.01/5.5/6.0 on Microsoft Windows platforms). Privacy Bird is the most complete P3P tool currently available. It is the first software to automatically read full P3P privacy policies and display them in an easy to understand language. It offers a wide variety of customization options, allowing you to tailor warning messages to meet your personal privacy concerns. For example, Privacy Bird allows you to ask for warnings at Web sites that may:

  • Sell your name and address to other companies without your permission
  • Use your health or medical information for marketing
  • Put you on mailing lists that you can't get off of
  • And more ....

As you spend more time on the Internet, more information about you and your Web activities is being shared with Web sites and may be used without your knowledge. It is difficult to determine which companies are getting access to your information or what they will do with it. Privacy Bird puts you in control, giving you quick access to information about Web site privacy policies and timely warnings about Web sites that may use your personal data for purposes that are not acceptable to you.

To learn more about this software, please take a tour or download a beta version of the software now.

PRIVACY BIRD¨ software was originally developed by AT&T Corp. As of version 1.3 Beta, it is now maintained by the CMU Usable Privacy and Security Laboratory at Carnegie Mellon University.
