2Sigma School is committed to protecting your privacy. Our privacy policy outlines what information we collect from you, how we use that information, and what choices you have regarding how and whether we can use your information.

We use this information to help us improve our website and learning content, and assess student engagement with the learning content.

Cookies: In operating our Sites, we and third parties that provide certain functionality to the 2Sigma School Services may use a technology called "cookies."

We may also use class recordings to provide feedback to Teachers, for customer support, and for compliance purposes.

We will obtain additional parental consent before we use any class recordings for promotional or other purposes. 2Sigma School and its affiliates may use your Personal Data to contact you in the future to tell you about services we believe will be of interest to you. If we do so, each promotional communication we send you will contain instructions permitting you to "opt-out" of receiving future promotional information. In addition, if at any time you wish not to receive any future communications or you wish to have your name deleted from our mailing lists, please contact us at Please note that we will continue to contact you via email and/or SMS to respond to requests and provide our Services.

If you are located outside the United States and choose to provide information to us, please note that we transfer the data, including Personal Data, to the United States and process it there.


We may share your Personal Data with certain third parties without further notice to you, as set forth below:

Business Transfers: If we are involved in a merger, acquisition, financing due diligence, reorganization, bankruptcy, receivership, sale of company assets, or transition of service to another provider, your information may be transferred to a successor or affiliate alone or as part of that transaction along with other assets.

Vendors and Service Providers: We engage third party vendors and service providers to perform certain functions on our behalf (such as payment processing, learning assessment, and so on). These third parties may have access to your Personal Data for the purpose of helping us market, provide and/or improve the Services.

Other Educational Institutions: We may share student enrollment information and their progress in the courses with educational institutions that we partner with for concurrent enrollment, in order to provide credits for our courses. Credits offered through those institutions are the sole responsibility of the institution, which is responsible for accreditation requirements.

Legal Requirements: We may disclose your Personal Data if required to do so by law or in the good faith belief that such action is necessary to (i) comply with a legal obligation, (ii) protect and defend the rights or property of 2Sigma School, (iii) act in urgent circumstances to protect the personal safety of users of the Site or the public, or (iv) protect against legal liability.

2Sigma School Instructors: We share Personal Data about students with our instructors to enable them to communicate with students and to help them understand each student's individual needs and capabilities.

Public Forums and Publicly Available Content: We may offer features that allow our students to share content in public or semi-public spaces. These are optional features, but if Students use them, they should do so under good judgement. Information they disclose in such areas of our Service may be read, collected, stored, or used by others. We do not systematically monitor the content of information that is published in the Public Forums.

We may share aggregated or de-identified information, which cannot reasonably be used to identify you, for various purposes including compliance with various reporting obligations; for business or marketing purposes; or to assist third parties in understanding our users' interests, habits, and usage patterns for certain content, services, programs, advertising and promotional purposes, and/or functionality available through our Service.


This section explains our information collection, disclosure, parental consent practices and parental choice procedures with respect to information provided by children under the age of 13 (“Child” or “Children”). This policy is in accordance with the U.S. Children's Online Privacy Protection Act (“COPPA”), and outlines our practices in the United States regarding Children's personal information. For more information about COPPA and general tips about protecting Children's online privacy, please visit OnGuard Online.

Collection: We collect information about students directly from Parents, who provide us with the Child's first name, age, type of schooling, local time zone, and additional notes for the Teacher. In addition, Children may share information about themselves during Classes. The 2Sigma School class sessions may take place over online videos in which video images and audio of the Children are recorded. No information is collected directly from Children until they are in the course session. Children cannot post personal data publicly on our Services.

Use and Disclosure: We share the name, age, local time zone, and any notes Parents have provided about their Child to the Class Teacher, in order to allow the Teacher to provide Classes. This information shall also be treated as part of the Parent's “Personal Data” and may be shared as described in the Disclosure section above for business transfers; to vendors and service providers; and to comply with legal requirements. Children may also share information about themselves with the Teacher and the rest of their class during the Class session voluntarily. While we expect Teachers and all other Users to abide by our standards of conduct, please note that we cannot control or monitor what personal information your Child shares with Teachers or other classmates, nor what those third parties ultimately do with that information, and we disclaim all responsibility in that regard.

Class Video Recordings: As described above, we record video of students and Teachers during our classes (“Class Recordings”). The Class Recordings are made available to the teacher of the class and may be shared with the entire class (and their Parents) to view (the “Permitted Recipients”). We may also use Class Recordings to provide feedback to Teachers, to assess and improve student engagement, for improving our curriculum, content, and pedagogy, for customer support, and for compliance purposes. We will obtain additional parental consent before we use any Class Recordings for promotional or other purposes. We utilize reasonable means to (i) limit the ability of Teachers to create copies of the Class Recordings or to share the Class Recordings with anyone aside from Permitted Recipients, and also (ii) limit the ability of Permitted Recipients to download or re-share the Class Recordings. While we expect Teachers and Permitted Recipients to abide by our standards of conduct, please note that we cannot control or monitor what such third parties ultimately do with Class Recordings, and disclaim all responsibility in that regard.

Parental Consent: We obtain verifiable parental consent before collecting Personal Data from your Child. We require that you provide your credit card information in order to register your Child for and pay for a 2Sigma School Class. If you do not consent, then we will not collect, use or disclose any personal information about your Child, and your Child will not be allowed to use the Services in any way. If you are not using our services for any other purposes and do not provide consent within a reasonable time from the date the direct notice was sent, we may also delete your online contact information from our records.

Parental Choices and Controls: At any time, you can refuse to permit us to collect further Personal Data from your Children in association with your account, and can request that we delete from our records the Personal Data we have collected in connection with that account. Please keep in mind that a request to delete records may lead to a termination of an account, membership, or other service. You may update your Child's information by logging onto your account. You can contact 2Sigma School to request access to, change, or delete your Child's personal information by sending an email to us at A valid request to delete personal information will be accommodated within a reasonable time. In addition to the foregoing, we will exercise commercially reasonable efforts to delete personal information belonging to Children when it is no longer needed for the purpose for which it was collected.


This Privacy Policy applies only to the 2Sigma School Services. The Services may contain links to other websites not operated or controlled by us (the “Third Party Sites”). The policies and procedures we describe here do not apply to the Third Party Sites. The links from our Services do not imply that we endorse or have reviewed the Third Party Sites. We suggest contacting those sites directly for information on their privacy policies.


We take reasonable steps to protect the Personal Data provided via the Services from loss, misuse and unauthorized access, disclosure, alteration, or destruction. However, the Internet cannot be guaranteed to be fully secure and we cannot ensure or warrant the security of any information you provide to us. We do not accept liability for disclosures beyond our reasonable control. You are also responsible for helping to protect the security of your account credentials.
