IF YOU HAVE AN ACCOUNT ON AMAZON.COM AND AN AMAZON.COM COOKIE, INFORMATION GATHERED BY AMAZON MECHANICAL TURK, AS DESCRIBED IN THIS PRIVACY NOTICE, MAY BE CORRELATED WITH ANY PERSONALLY IDENTIFIABLE INFORMATION THAT AMAZON.COM HAS AND USED BY AMAZON MECHANICAL TURK AND AMAZON.COM TO IMPROVE THE SERVICES WE OFFER.

What Personal Information About Users Does Amazon Mechanical Turk Gather?

The information we learn from users helps us personalize and continually improve your experience at the Amazon Mechanical Turk site. Here are the types of information we gather.

  • Information You Give Us: We receive and store any information you enter on our Web site or give us in any other way. Specifically, to register with the Amazon Mechanical Turk site, you must provide us your name, email and physical address. Click here to see examples of what other information we collect. You can choose not to provide certain information, but then you might not be able to take advantage of many of our features. We use the information that you provide for such purposes as responding to your requests, customizing the site for you, improving our site, and communicating with you.
  • Automatic Information: We receive and store certain types of information whenever you interact with us. For example, like many Web sites, we use "cookies," and we obtain certain types of information when your Web browser accesses the Amazon Mechanical Turk site. Click here to see examples of the information we receive. A number of companies offer utilities designed to help you visit Web sites anonymously. Although we will not be able to provide you with a personalized experience at Amazon Mechanical Turk if we cannot recognize you, we want you to be aware that these tools exist.
  • E-mail Communications: By registering on the Amazon Mechanical Turk site, you will receive emails from Amazon Mechanical Turk and/or its Affiliates. As a Amazon Mechanical Turk site participant, it may be necessary for us to communicate with you to provide essential operational updates, status reports, transaction information, notices in connection with your account and other information relevant to your participation and use of the Web site (collectively "Essential Communications"). You may not opt out of such Essential Communications, and you agree to receipt of Essential Communications via email and/or other communication methods provided by you in your account registration. If we send newsletters and other non-essential email communications, we will give you the opportunity to unsubscribe to them. To help us make e-mails more useful and interesting, we may receive a confirmation when you open email from Amazon Mechanical Turk if your computer supports such capabilities.
  • Information from Other Sources: We might receive information about you from other sources and add it to our account information.

What About Cookies?

  • Cookies are alphanumeric identifiers that we transfer to your computer's hard drive through your Web browser to enable our systems to recognize your browser and to provide features such as personalization.
  • The Help portion of the toolbar on most browsers will tell you how to prevent your browser from accepting new cookies, how to have the browser notify you when you receive a new cookie, or how to disable cookies altogether. However, cookies allow you to take full advantage of the Amazon Mechanical Turk site's features, and in order to participate, you must leave them turned on.

Does Amazon Mechanical Turk Share the Information It Receives?

Information about our users is an important part of our business, and we are not in the business of selling it to others. We are a subsidiary of Amazon.com, Inc., and we share user information only as described below and with subsidiaries Amazon.com, Inc. controls.

  • With Your Consent: By accepting the Amazon Mechanical Turk Participation Agreement, you expressly consent to our use of your information as outlined in this Privacy Notice.
  • Participants: As a requester or provider of services through the Amazon Mechanical Turk site, we may share certain information in order to facilitate the service relationship and to improve the Web site. For example, account numbers, account names, feedback, ratings and other attributes relating to use of the service may be publicly displayed on the Web site. In addition, service requesters may require prospective service providers to disclose additional information about themselves as a condition to accepting services from those service providers.
  • Agents: We employ other companies and individuals to perform functions on our behalf. Examples include analyzing data, processing payments, and providing customer service. They have access to personal information needed to perform their functions, but may not use it for other purposes.
  • Promotional Offers: We may send offers to selected groups of Amazon Mechanical Turk users on behalf of other businesses. When we do this, we do not give that business your personal information. If you do not want to receive such offers, we will give you the opportunity to unsubscribe to them.
  • Business Transfers: As we continue to develop our business, we might sell or buy additional services or business units. In such transactions, user information generally is one of the transferred business assets but remains subject to the promises made in any pre-existing Privacy Notice (unless, of course, the user consents otherwise). Also, in the event that Amazon Mechanical Turk or substantially all of its assets are acquired, user information will of course be one of the transferred assets.
  • Protection of Amazon Mechanical Turk and Others: We release account and other personal information when we believe release is appropriate to comply with the law; enforce or apply our Participation Agreement and other agreements; or protect the rights, property, or safety of Amazon Mechanical Turk, our users, or others. This includes (1) exchanging information with other companies and organizations for fraud protection and credit risk reduction; and (2) if you are a provider of a service on the Amazon Mechanical Turk site, we will release your name and address only to requesters for whom you provide services so that those requestors can comply with tax and other legal obligations they might have. Obviously, however, this does not include selling, renting, sharing, or otherwise disclosing personally identifiable information from users for commercial purposes in violation of the commitments set forth in this Privacy Notice.

How Secure Is Information About Me?

  • We work to protect the security of your information during transmission by using Secure Socket Layer (SSL) software, which encrypts information you input.
  • It is important for you to protect against unauthorized access to your password and to your computer. Be sure to sign off when finished using a shared computer.

What Choices and Access Do I Have?

  • As discussed above, you can always choose not to provide information, even though it might be needed to take advantage of the Amazon Mechanical Turk site.
  • You can add or update certain information, such as your e-mail address or account information by going to the "Your Account" feature of the Web site. When you update information, we usually keep a copy of the prior version for our records.
  • The Help portion of the toolbar on most browsers will tell you how to prevent your browser from accepting new cookies, how to have the browser notify you when you receive a new cookie, or how to disable cookies altogether. However, you will not be able to use the Amazon Mechanical Turk site if you do not use cookies.
