EdX and each Member that provides courses through the edX Site care about the confidentiality and security of your information. This Privacy Policy applies to information that edX collects through the edX Site when you interact with edX, with Members, with other users, and generally with the edX Site.

Your information is received and controlled by edX according to this Privacy Policy when you sign up for an edX account or otherwise use the edX Site.

  • EdX is solely and independently responsible for its own privacy practices. No Member is responsible for edX’s privacy practices.

If you enroll in a course offered by a Member through the edX Site, information about you and your activity in the course is received and controlled also by that Member as described in this Privacy Policy.

  • Each Member is solely and independently responsible for its own privacy practices. No Member is responsible for another Member’s privacy practices. Also, edX is not responsible for any Member’s privacy practices.

If you do not accept the terms of this Privacy Policy, then please do not access, browse, or register for the edX Site or enroll in any courses. If you choose not to provide certain information required to provide you with various products and services offered on the edX Site, then you may not be able to establish a user account or obtain those products or services.

Any version of this Privacy Policy in a language other than English is provided for convenience and you understand and agree that the English language version will control if there is any conflict.

This Privacy Policy is organized as follows:

Information that edX Collects from You (Including Personal Information)

  • sign up for an edX user account and create an edX user profile;
  • enroll and participate in online courses;
  • purchase a product or service (for example, Verified Certificates);
  • send email messages to edX (including messages to learner support);
  • participate in user surveys; and

90从前面动插图前入里EdX does not itself collect or store financial account numbers or identification issued by a governmental entity, employer, or other authority. Instead, if you choose to make a purchase on the edX Site, for example a Verified Certificate, you will be directed to edX’s third-party payment processor and edX’s third-party ID verification service provider. If you do not wish to submit the required authentication or payment information, then you will not be able to obtain a certificate via the edX Site.

EdX requires your Personal Information90从前面动插图前入里 limited circumstances when you:

  • sign up for an edX user account (name, username, email address);
  • purchase a Verified Certificate (so that edX’s third-party vendor can authenticate your identity) or other product or service (so that edX’s third-party vendor can process payment);
  • participate in remote proctoring or other course facilitation processes (so that edX’s third-party vendor can monitor and assess the integrity of your course activity); or
  • earn a Verified Certificate (the certificate will have your name on it).

To the extent that edX associates the information that edX collects directly or indirectly with an individual (for example, you), the association is based on Personal Information in your account profile.

You may voluntarily choose to share additional Personal Information on the edX Site, for example:

  • in your edX account profile (and you may display a limited or full profile to other edX Site users);
  • in applying for financial assistance; or
  • when participating in a course, forum, webinar, or other interactive experience on the edX Site (noting that in some cases, this information is shared with a third party that provides tools or other assistance for the edX Site or a course).

EdX encourages you to use discretion before voluntarily sharing additional Personal Information on the edX Site. (If you later choose to delete your edX account, deletion of your Personal Information90从前面动插图前入里 will be subject to the process and limits outlined below.)

Members do not receive your Personal Information unless and until you enroll in a course. If you enroll in a course, the Member that offers the course will receive Personal Information from your edX account profile plus the information that edX collects about your activity and performance in the course in which you enrolled.

Cookies And Tracking Technologies on the edX Site

Like many companies, edX uses Cookies and other common Tracking Technologies on the edX Site and in email communications to help edX better understand your use and needs of the edX Site, current and future edX-related products and services, and how edX and Members can improve. For example:

  • based on your cookie settings, edX tracks information indicating, among other things, which pages of the edX Site were visited, the order in which they were visited, when they were visited, and which hyperlinks and other user interface controls were used;
  • edX may log the IP address, operating system, and browser software (including mobile use and device type when you use edX native mobile apps) you used when accessing the edX Site, and edX may be able to determine from an IP address your Internet Service Provider and the geographic location of your point of connectivity; and
  • edX may track and collect information from emails that edX sends to you, for example whether you opened the email or clicked on any links from the email.

90从前面动插图前入里EdX also partners with third parties to help us track and understand your activity on the edX Site, how you interact with edX’s social media, and how you find or may be referred to the edX Site. Individual Members may separately use Tracking Technologies within their courses and email communications to understand your activity within a course and how you find or may be referred to a course on the edX Site.

EdX and Members use Cookies and other Tracking Technologies for the following purposes:

  • when necessary for system administration, security, and integrity to ensure the edX Site works properly for you. Without these technologies, the edX Site may not function correctly;
  • to enable analytics, performance and functionality, to help edX and Members gather information about how visitors use the edX Site and monitor edX Site performance, and to enhance your experience by recognizing and remembering whether you have visited the edX Site before and may have any personal preferences; and
  • to support marketing by enabling edX and Members to deliver content relevant to your interests on the edX Site and third-party sites based on how you interact with edX or Member advertisements or content. EdX and Members use “first-party” cookies, which means cookies served by edX or an individual Member, and also “third-party” cookies, which means cookies served by third parties that help edX and Members track this information.

You have some options for managing Cookies and other Tracking Technologies. These include:

  • Modifying your browser settings: You should be able to control how and whether your web browser accepts Cookies by adjusting its privacy and security settings. The “help” feature of the menu bar on most browsers will tell you how to stop accepting new Cookies, how to receive notification of new Cookies, and how to disable existing Cookies. If you reject edX’s Cookies, many functions and conveniences of the edX Site may not work properly.
  • Opting-out of certain third-party tracking and advertising: Some of the third parties used by edX or a Member for Cookies and Tracking Technologies offer the ability to opt-out from their tracking by following processes described on their websites. A list of some such third parties is maintained and available at the and includes, for some, links to applicable opt-out processes. Neither edX nor any Member is responsible for the effectiveness of any third-party opt-out options.

90从前面动插图前入里EdX or a Member may also seek your consent for additional uses of information, including Personal Information, and will use it only for the purpose described to you. All use of Personal Information is subject to applicable law.

How Your Information Is Shared

EdX and Members share information, including Personal Information90从前面动插图前入里, with third parties for the following purposes:

  • With service providers, contractors, and other third parties that help carry out the uses described above – EdX requires third parties to: (1) abide by this Privacy Policy and applicable law; (2) handle Personal Information in a confidential manner and maintain adequate security; and (3) use Personal Information only as needed to fulfill the relevant purpose(s). In some cases, the edX Site and individual courses are integrated with third-party services or contain links to websites published by third parties, including other content providers as well as service providers. These third parties are responsible for their own privacy practices, so you should pay attention anytime you are redirected to a third-party website and be sure to review its privacy policy.
  • With other learners in courses that you take and with other visitors to the edX Site, to create an interactive learning environment, support class participation, and share course information – This includes sharing comments, coursework, or other information or content that you submit to a portion of the edX Site designed for viewing by other class members or for public communication. This also includes providing opportunities for you to communicate with other users who may have similar interests or educational goals, for instance, recommending specific study partners or connecting potential student mentees and mentors. In such cases, edX and each Member that offers a course in which you enrolled may use all information collected about you to determine who might be interested in communicating with you, but will only provide others your username (for clarity, no disclosure of your real name or email address).
  • With employers, government programs, institutions, or other enterprises that sponsor your enrollment in a course for training or other educational purposes – If an entity pays for or otherwise sponsors your Verified Certificate or course participation, edX will share information with the entity as needed to confirm your enrollment, participation, progress, and completion status in that course.
  • With affiliates of edX or a Member, or with successors in the event of a merger, acquisition, or reorganization, for their use consistent with this Privacy Policy.

90从前面动插图前入里EdX or a Member may also seek your consent for additional disclosures of information, including Personal Information, and will share it only as described to you. In addition, edX or a Member may share with the public and with third parties, including but not limited to researchers and business partners, information and Personal Information that is de-identified or aggregated in a manner that does not personally identify you.

How to Manage Your Personal Information

You can manage your Personal Information through learner features on the edX Site and requests to the edX learner support team. If your request involves information controlled by a Member, edX learner support will notify and coordinate with the appropriate Member to address your request. EdX will provide support to the extent required by applicable law (for example, learners in the European Union) and more broadly when possible, as a courtesy in our sole discretion. EdX will notify you in the event that edX is unable to meet a request that is not legally required. Similarly, Members will only be obligated to comply with requests to the extent legally required, but may choose to comply with other requests in their sole discretion.

Access and correct your Personal Information

Much of your Personal Information is available in your edX account. Your name, email address, and other identifiable profile information is editable through the profile settings in your edX account except as noted below. Your account dashboard lists all current and archived courses in which you have enrolled and includes links to any Verified Certificates90从前面动插图前入里 you may have earned. The dashboard also contains copies of your answers and other participation and performance in courses. Please contact edX learner support to access and update this or other information. If your request involves information controlled by a Member, edX learner support will notify the appropriate Member of your request.

Exceptions:

  • Usernames cannot ever be changed. This is an edX system restriction. Because usernames identify you in courses and elsewhere on the edX Site, edX encourages you to use discretion in choosing your username. If you want to protect your identity, do not use your real name or a name identifiable to you as your username.
  • EdX does not track or index every time or every place on the edX Site when or where a learner may volunteer Personal Information, so neither edX nor Members will be able to help you locate or manage all such instances. EdX encourages you to use discretion before volunteering Personal Information on the edX Site.

Restrict or object to the processing of Personal Information

If you want to manage emails and other communications to you, you may update your preferences in your edX account dashboard, follow the steps described in links at the bottom of email messages, or contact edX learner support. You may object to, or request that edX or a Member stop, its use of your Personal Information for other purposes by contacting the edX learner support team. If your request involves information controlled by a Member, edX learner support will notify the appropriate Member of your request. Please note that if you choose to restrict edX’s or a Member’s ability to process Personal Information, and the processing is otherwise required to provide you with various services and products offered on the edX Site, you may not be able to establish an edX user account or enroll for a course, and edX or a Member may not be able to provide you with those services or products.

Delete account and Personal Information

90从前面动插图前入里To request deletion of your edX account and Personal Information, you should click the button labeled “Delete my account” in your edX account settings. Because deletion on the edX system is a permanent action and cannot be reversed, edX may ask you to complete a process that aims to confirm your authority to manage the edX account affected by your request.

With respect to your edX account, edX will permanently:

  • deactivate your edX account,
  • remove the active profile,
  • retire your username, and
  • remove you from edX email lists.

With respect to your Personal Information, edX will permanently90从前面动插图前入里 delete your edX account profile Personal Information from the edX Site.

As noted above90从前面动插图前入里, to the extent that edX associates the information that edX collects directly or indirectly with an individual (for example, you), the association is based on Personal Information in your edX account profile. By erasing the Personal Information in your edX account profile, the remaining information about your activity on the edX Site will no longer be associated with you, except as noted below.

These changes will be applied to data stores that are used for operation of the edX Site including course administration by Members. If you enrolled in any courses on the edX Site, the edX learner support team will share your request with the Members that offered those courses.

Exceptions:

  • Deletion will not apply to historical activity logs or archives unless and until these logs and data naturally "age-off" the edX system.
  • EdX does not track or index every time or every place on the edX Site when or where a learner may volunteer Personal Information, so neither edX nor Members will be able to help you locate or manage all such instances. EdX encourages you to use discretion before voluntarily sharing your Personal Information on the edX Site.
  • EdX will archive course data (in a manner and to the extent permitted under applicable law) to serve its mission to enable scientific research on cognitive science and education. These archives are used to produce encrypted research data packages for Members, and Personal Information may not be deleted from research data packages retained by Members.
  • EdX and each applicable Member cannot always delete records of past interactions and transactions. For example, records relating to previous purchases on the edX Site must be retained for financial reporting, audit, and compliance reasons.
  • EdX and each Member will retain and use Personal Information as necessary to comply with its legal obligations, resolve disputes, enforce its agreements, and as otherwise permitted by applicable law.

Data retention

EdX will retain your Personal Information for as long as your account is active or as needed to provide you with services; to maintain a record of your transactions for financial reporting, audit, and compliance purposes; and to comply with edX’s legal obligations, resolve disputes, enforce its agreements, and as otherwise permitted by applicable law. If you enroll in a Member’s course, such Member will also retain your Personal Information for as long as needed to provide you with services; to maintain a record of your transactions for financial reporting, audit, and compliance purposes; and to comply with its legal obligations, resolve disputes, enforce its agreements, and as otherwise permitted by applicable law. Upon your request that edX deactivate your account and delete your information, edX will follow the process described above, including without limitation archiving your course data (in a manner and to the extent permitted under applicable law) to serve its mission to enable scientific research on cognitive science and education. These archives will be used to produce encrypted research data packages for Members, and each such Member may also keep and use course data for scientific research.

Storage & Security

EdX stores information, including Personal Information, on its own servers and also on servers of companies that edX hires to provide services. Each Member90从前面动插图前入里 also stores information, including Personal Information, on its own servers and/or on servers of companies that the Member hires to provide services. In each case, information may be stored in the United States and in other countries where edX or a Member operates, and in countries where edX and each Member’s respective service providers operate. If you are in the European Union, Switzerland, or other regions with laws governing data collection and use, you acknowledge that edX and each Member may transfer, process and store your personal information in the United States and other countries, the privacy laws of which may be considered less strict than those of your region.

EdX controls its own copy of information collected through the edX Site90从前面动插图前入里 and has an information security program designed to protect information in its possession or control. This is done through a variety of privacy and security policies, processes, and procedures. EdX uses administrative, physical, and technical safeguards that reasonably and appropriately protect the confidentiality, integrity, and availability of the information that it collects, receives, stores, or transmits. Nonetheless, no method of transmission over the Internet, or method of electronic storage, is 100% secure; and therefore, edX cannot guarantee its absolute security. While edX works hard to ensure the integrity and security of its network and systems, edX cannot guarantee that its security measures will prevent "hackers" or other unauthorized persons from illegally accessing or obtaining information.

90从前面动插图前入里If edX learns of a security breach involving its copy of your Personal Information, edX may attempt to notify you electronically so that you may take appropriate protective steps. By using the edX Site or providing Personal Information to edX, you agree that edX can communicate with you electronically regarding security, privacy, and administrative issues relating to your use of the edX Site. If a security systems breach occurs, edX may post a notice on the edX homepage (www.diaosheng8.com) or elsewhere on the edX Site and may send an email to you at the email address associated with your edX account. Depending on where you are located, you may have a legal right to receive notice of a security breach, involving your Personal Information, in writing.

90从前面动插图前入里If a Member learns of a security breach involving that Member’s copy of your Personal Information, the Member may attempt to notify you electronically so that you may take appropriate protective steps. By enrolling in a Member’s course on the edX Site or providing Personal Information to the Member, you agree that the Member can communicate with you electronically regarding security, privacy, and administrative issues relating to your course enrollment and participation. If a security systems breach occurs, the affected Member may post a notice on the edX site and/or send an email to you at the email address associated with your enrollment in the Member’s course on the edX Site. Depending on where you are located, you may have a legal right to receive notice of a security breach, involving your Personal Information, in writing.
