Privacy Policy

By accessing or using the Services (including without limitation the mobile version of the Platform (the “Mobile Site”), you acknowledge that you accept and consent to the practices and policies outlined in this Privacy Policy. Remember that your use of NetDragon’s Services is at all times subject to the Terms of Service, which incorporates this Privacy Policy. Any terms we use here without defining them have the definitions given to them in the Terms of Service.

Please read on to learn more about how we collect and use your information; if you have any questions or concerns regarding our privacy practices, please reach us at

What does this privacy policy cover?

This Privacy Policy explains how NetDragon collects and uses information from its users, including our treatment of personally identifiable information. This policy does not apply to websites or the practices of companies that NetDragon does not own or control, or to individuals that NetDragon does not employ or manage, such as the third party links on the Services and third parties who publish their content via the Services.

How is children’s personal information treated?

If you are not of legal age to form a binding contract (in many jurisdictions, this age is 18), you may only use the Services and disclose information to us with your parent’s or guardian’s consent. Review this Privacy Policy with your parent or guardian and make sure you understand it, and do the same with the privacy policies of all websites you visit or mobile applications you use.

We only collect personal information through the Services from a child we know is under the age of 13 (or under the age of 16 for a child in the European Union) (each a “child”) when we have parental consent or when a student’s school, district, and/or teacher has agreed (via the terms described in more detail in the Terms of Service) to obtain parental consent for that child to use the Services and disclose personal information to us, for the use and benefit of the learning environment. If you are a child, please do not send any personal information about yourself to us if your parent has not provided consent or your school, district, and/or teacher has not obtained this prior consent from your parent or guardian, and please do not send any personal information other than what we request from you in connection with the Services. If we learn we have collected personal information from a child without appropriate consent as outlined herein, we will delete that information as quickly as possible. If you believe that a child may have provided us personal information in violation of this paragraph, please contact us at

When we use the term “Personal Information” in this Privacy Policy, we are referring to personally identifiable information of individual, non-student registrants of the Services. References to “Children’s Personal Information” only apply to personally identifiable information of users who have registered for the Services as minor students (i.e., students under the age of 18). General references to “information” apply to all users.

If you are a student registrant and your parent or guardian has signed up for the Services with an Access Code provided by your teacher, you understand that your parent or guardian, teacher, or school administrator can view all information within or associated with your Services account, including, without limitation, messages between you and your teacher and grades you received on assignments.

Most browsers have an option for turning off the cookie feature, which will prevent your browser from accepting new cookies, as well as (depending on the sophistication of your browser software) allowing you to decide on acceptance of each new cookie in a variety of ways. We strongly recommend that you leave NetDragon cookies activated, however, because you may not be able to log in or use many of the Services’ most attractive features without cookies enabled.

The Services may also contain electronic images known as web beacons (sometimes called single-pixel gifs), which are used along with cookies to compile aggregated statistics to analyze how the Services are used.

Usage Information

NetDragon uses this type of aggregate data to enable us to figure out how often users use parts of the Services, so that we can make the Services appealing and relevant to as many users as possible, and customize and improve those Services. We may link usage information to Personal Information that we collect through the Services, but we will only use this linked information internally (for example, to customize your experience), and will not disclose it in linked format to third parties. Additionally, certain usage-related information may be viewable in your user profile that may be displayed to other users, depending on your User Category; for example, the view rate of the video you uploaded can be seen by other users in your organisation.


NetDragon does not provide any personally-identifying information to advertisers or our advertising partners. Nor do we sell or rent your personal information to anyone for any purposes, including advertising or marketing. NetDragon does not create behavioral profiles of users for advertising or marketing purposes, and we are not sharing personally-identifiable information, such as a user’s name, email address, or phone number, with third parties for advertising purposes.
