What are cookies and similar technologies?
Cookies are small text files placed by a website and stored by your browser on your device. A cookie can later be read when your browser connects to a web server in the same domain that placed the cookie. The text in a cookie contains a string of numbers and letters that may uniquely identify your device and can contain other information as well. This allows the web server to recognize your browser over time, each time it connects to that web server.
Web beacons are electronic images (also called single-pixel or clear GIFs) that are contained within a website or email. When your browser opens a webpage or email that contains a web beacon, it automatically connects to the web server that hosts the image (typically operated by a third party). This allows that web server to log information about your device and to set and read its own cookies. In the same way, third-party content on our websites (such as embedded videos, plug-ins, or ads) results in your browser connecting to the third-party web server that hosts that content. We also include web beacons in our promotional email messages or newsletters to tell us if you open and act on them.
The purposes for which we use these technologies may include the following:
- Analytics. Our site contains cookies or web beacons, including from third-party providers, to analyze the use of our products, services or applications. For example, our site uses Google Analytics to help us understand how users interact with our website; you can learn how Google collects and uses information at google.com/policies/privacy/partners and you can opt out of tracking by Google Analytics by visiting tools.google.com/dlpage/gaoptout.
- Advertising and marketing. We may use third party partners to assist with our promotional and marketing efforts (including behavioral advertising). See below for tools that can help you opt-out from behavioral advertising.
- Third party content and social media. We sometimes offer content of third party sites (including social media content).
What controls are available?
- Advertising controls. Many third party advertising companies participate in associations that provide simple ways to opt out of ad targeting, which you can access at:
These choices are specific to the browser you are using. If you access our services from other devices or browsers, take these actions from those systems to ensure your choices apply to the data collected when you use those systems.
- Browser cookie controls. Most web browsers are set to accept cookies by default. If you prefer, you can go to your browser settings to learn how to delete or reject cookies. If you choose to delete or reject cookies, this could affect certain features or services of our website. If you choose to delete cookies, settings and preferences controlled by those cookies, including advertising preferences, may be deleted and may need to be recreated.
- Mobile advertising ID controls. iOS and Android operating systems provide options to limit tracking and/or reset the advertising IDs.
- Email web beacons. Most email clients have settings which allow you to prevent the automatic downloading of images, including web beacons, which prevents the automatic connection to the web servers that host those images.
- Do Not Track. Some browsers have incorporated "Do Not Track" (DNT) features that can send a signal to the websites you visit indicating you do not wish to be tracked. Because there is not a common understanding of how to interpret the DNT signal, our websites do not currently respond to browser DNT signals. Instead, you can use the range of other tools to control data collection and use, including the cookie controls and advertising controls described above.
