What is a cookie?
A cookie is a small text file that a web server places on your computer or mobile device when you visit a website. This small text file may include a unique identifier that distinguishes your computer or mobile device from other devices. Cookies serve a number of purposes such as letting you navigate between webpages efficiently, remembering your preferences, and generally improving the user experience. Cookies may tell us, for example, whether you have visited the Tableau Sites before or whether you are a new visitor. They can also help to ensure that content we display, advertisements you see online, and marketing messages are more relevant to you and your interests.
How long do cookies last?
Cookies can remain on your computer or mobile device for different periods of time. Some cookies are “session cookies.” These exist only while your browser is open and are deleted automatically once you close your browser. Other cookies are “persistent cookies.” These cookies survive after your browser is closed until a defined expiration date. They can be used by websites to recognize your computer when you open your browser and browse the Internet again.
What other technologies are used to track my website visits?
We and others may also use other technologies for tracking, such as pixel tags and web beacons. Web beacons and pixel tags are electronic images that may be used on Tableau Sites or in our emails. We use web beacons, for example, to deliver cookies, to count visits, to understand usage of the Tableau Sites and Tableau’s services, to analyze the effectiveness of Tableau Site features and campaigns, and to tell if an email has been opened and acted upon.

How to manage or delete cookies on Tableau Sites
The following are examples of how you can manage or delete many of the cookies served through the Tableau Sites:
- Cookie opt-out links. You may manage or opt-out of certain uses of many cookies served through the Tableau Sites by using the links provided above.
- Industry opt-out sites. You may also opt-out of certain use of many cookies served for advertising purposes by many of Tableau’s third party advertising partners by visiting either: http://www.aboutads.info/choices/ or http://www.networkadvertising.org/choices/.
- Browser settings. Many web browsers accept cookies by default. If you prefer, you can usually change your browser's settings to reject and/or to remove many cookies. On some browsers, you can choose to let the Tableau Sites place cookies, but choose to reject cookies from certain third parties (such as analytics companies and advertising companies). As the precise means by which you may do this will vary from browser to browser, please visit your browser's help or settings menu for more information. Please note also that if you choose to reject or remove cookies, this may prevent certain features or services of Tableau Sites from working properly. Since your cookie opt-out preferences are also stored in a cookie in your website browser, please also note that if you delete all cookies, use a different browser, or buy a new computer, you will need to renew your opt-out choices.
Tableau may also use e-mail tracking technologies to monitor the success of e-mail campaigns it operates (for example, recording how many e-mails in a campaign were opened). If you do not want us to track emails we send you, some email services let you change your display to turn off HTML or disable download of images and exercising these rights should effectively disable our email tracking. In addition, you may also unsubscribe from our marketing emails as described in those emails.
Do Not Track
Some Internet browsers include the ability to transmit “Do Not Track” signals. Since uniform standards for “Do Not Track” signals have not been adopted, the Tableau Sites do not currently process or respond to “Do Not Track” signals. To learn more about “Do Not Track”, please visit “All About Do Not Track" (http://www.allaboutdnt.com/). In addition to “Do Not Track”, there are many ways that web browser signals and similar mechanisms can indicate your tracking choices, and we may not be aware of nor honor every mechanism.
