Browser Apps

This page documents our current privacy practices for browser apps - including extensions, add-ons and plug-ins - such as Yahoo Toolbar and those provided by ClarityRay Solutions, an Yahoo company.

Information Collection and Use Practices

  • Browser apps for Yahoo products and services are extensions of those services and the privacy information page for each will reflect our privacy practices as if you were using that service in a web browser.
  • We track clicks on our browser apps for reasons that include improving our products and services.
  • Toolbar apps are buttons that allow you to interact with web services provided by Yahoo and third-parties.
    • When you use a Toolbar app to access third-party services such as Facebook, Yahoo does not track activities within the panel where you interact with that third-party. That third-party may collect information within the panel as you interact with its services.

Web Usage

  • Some browser apps, including Yahoo Toolbar, may share information with Yahoo about your device and the sites you visit to help us personalize your online experience; detect malware and other software that injects or blocks advertisements; and improve our products and services.
  • When enabled, such app will transmit information to Yahoo about the web page you’re visiting. This information may include the complete web site addresses (URLs) from all webpages you visit, referring and redirected URLs, IFrame URLs, script calls, name and URL of pop-up windows, unique Toolbar identifiers, product performance data like page load speed, the effect the advertising blocking and/or insertion software has on such web pages, device ID, and other information provided by your browser including domain cookies.
  • All domain cookies are transmitted automatically to us by your browser when this feature is enabled. Yahoo selectively records only certain cookies with usage data for that particular Yahoo app and does not store cookies that contain or are associated with Yahoo account IDs.
  • The setting for this feature is independent of other privacy preferences you may have expressed to Yahoo or made in your browser. For example, this setting does not change the selections you made in the Ad Interest Manager and, vice versa, selections you made in the Ad Interest Manager do not affect the collection of information through this feature.
  • You can disable this feature at any time through the options for the browser app you’re using. From the respective extensions manager, click “preferences” in Firefox and “options” in Chrome. If you’re using Yahoo Toolbar, you can also click the gear on the right side and choose the settings menu.

Software detection

  • Some of our browser apps will automatically detect other software installed in your device for purposes that may include identifying software that injects or blocks advertisements, determining if the software is involved in fraudulent activity, and finding software that is a network security threat. The app will collect identifying characteristics and other details about such software.
  • We may use the information gathered to help diagnose problems with and improve our products and services. We may also help other companies by providing details about the scope and nature of how they are impacted; however, this will not include personally identifiable information.

Updating or Deleting Information

  • By default, Yahoo Toolbar settings are stored on the computer where Toolbar is installed. Sign into the Toolbar and save your settings to store them in your account and use them across different browsers or devices.

How to Uninstall

  • You can uninstall browser apps you no longer wish to use. Uninstalling an app does not affect your account, will not alter your cookies, nor limit your access to other Yahoo services.
