Yahoo may set and read cookies and device identifiers when you visit our websites, use our products or visit a website where Yahoo provides ads, content or analytics. A cookie is a small piece of information that is stored on a computer for the purpose of identifying that particular browser during interaction on websites. Device identifiers are assembled from the system elements available, which could include the IP address, user agent information (browser version, OS type and version) or device-generated identifiers such as Apple’s ID for advertisers, Apple's ID for vendors, Google’s Android ID or Google's Play Store ad ID. Cookies and similar technology may be used to remember items such as identifiers and user preferences, and to identify and recognise Yahoo users. A website may set a cookie to the browser if the browser's preferences allow it. A browser only permits a website to access the cookies that it has set, not those set by other websites.

Yahoo7's Practices Regarding Identifiers and Cookies

Yahoo7 may use cookies for a number of purposes, including to:

  • Access your information when you "sign in" so we can provide you with customised content or remember the last page you visited in a Yahoo7 product or service.
    • Information that Yahoo7 collects related to your activities and interests is maintained by Yahoo7 on its servers and is associated with Yahoo7 cookies regardless of what computer or device you use to sign in to Yahoo7. You can learn more about Yahoo7’s data retention and storage practices here.
  • Maintain your settings and identity while you are using Yahoo products or services.
    • When you log in to your Yahoo account, a cookie and/or device ID that links to information about your interests is placed on the computer or device that you are using. This allows Yahoo to associate your interests, activities, preferences and prior Yahoo use if you log in to your Yahoo account on multiple devices. This means that your browsing habits or any other activity on your work computer, library computer or another device when logged in can inform your experience on Yahoo when using your home computer or another device when logged in.
  • Deliver advertisements and content relevant to your interests.
    • Yahoo7 collects and maintains information about your interests based on your websurfing activity when you are visiting the branded Yahoo7 network of websites, websites within the Yahoo7 Network, as well as other non-Yahoo7 web sites that we partner with.
    • Yahoo7 may use web beacons to collect and maintain information about your websurfing activity when you are visiting the branded Yahoo7 network of websites as well as other non-Yahoo7 websites.
  • Provide general internal and customer analytics.
    • Yahoo Analytics is a system used to collect information about visitors to our customers’ websites, or the use of our customers' services or apps.
  • Maintain information in both identifiable and anonymous forms.
    • When you are signed-in to your Yahoo7 account, Yahoo7 associates your observed interests and activities with your Yahoo7 account using a process that keeps your personal information and your browsing information separate.
    • If you are a registered Yahoo user who is not signed in, Yahoo stores information about your interests based on a browser cookie ID. This cookie ID is an encrypted (or ‘one-way secret hashed’) form of a Yahoo cookie that is separate from your Yahoo account information and also includes the age (in whole years), gender and location provided when you created your Yahoo account. Your device ID or other identifiers may be associated with this cookie ID for each device that you log in to, and your device or cookie IDs may also be associated with other devices in a similar location, such as within a household. This cookie is not used by any party, including Yahoo, to identify you personally.
  • Conduct research to improve Yahoo7's content, products and services.
  • To support security measures, such as requiring re-logging into a Yahoo7 product or service after a certain amount of time has elapsed.
  • To assist in identifying possible fraudulent activities.

Choices about Cookies

  • To see and/or customise the interests assigned to your browser that we use for customised advertising and content, you can visit our Ad Interest Manager. Ad Interest Manager allows you to opt-out of one or more specific interest categories or opt-out of all interest-based ads and content that Yahoo7 serves.
    • Yahoo7 offers you the ability to make your opt-out choice persistent. To use the persistent opt-out, you will need to sign-in to Yahoo7 before you exercise your opt-out choice.
  • You may configure your browser to accept all cookies, reject all cookies, or notify you when a cookie is set. Each browser is different, so check the "Help" menu of your browser to learn how to change your cookie preferences.
  • Most mobile operating systems provide you with an option in the device settings to limit ad tracking associated with certain device IDs that they may share with us. Even when you exercise this option, we may still use other information that we obtain from devices and apps for fraud, security, analytics, product improvement and attribution purposes. Please refer to your mobile operating system’s Help Centre to learn more.
  • Once you log into Yahoo on your device, Yahoo may recognize your device to provide you with a personalized experience (even if you log out), independent of your device settings. Your device's privacy settings may not provide you with full control over your privacy but you can control Yahoo ad targeting and personalization through our Ad Interest Manager. To opt out of Yahoo personalization, please visit the Yahoo Ad Interest Manager to configure your settings directly with Yahoo.
  • The Adobe Flash Player is an application and web tool that allows rapid development of dynamic content. Flash (and similar applications) use technology to remember settings, preferences and usage similar to browser cookies but these are managed through a different interface than the one provided by your web browser.
    • Yahoo7 employs Adobe Flash cookies in compliance with Interactive Agency Bureau standards. Yahoo7 employs Adobe Flash cookies in certain situations where we use Flash to provide some content such as video clips or animation. You may access your Flash management tools from Adobe’s web site directly. Yahoo7 does not use Flash cookies to serve interest-based advertising.
  • If you reject all cookies, you may not be able to use Yahoo7 products or services that require you to "sign in," and you may not be able to take full advantage of all offerings.
  • You can visit the Interactive Advertising Bureau to see other companies that offer opt outs and to use other tools to manage your opt-out choices.

Other Companies' Cookies on Yahoo7

  • In addition to Yahoo7 using cookies on our network of websites, we allow certain Third Parties to set and access their cookies on your computer. These companies use of cookies is subject to their own privacy policies, not the Yahoo7 Privacy Policy.
