ALPS by 2Sigma Terms of Service

Updated August 9, 2026

Welcome, and thank you for your interest in ALPS by 2Sigma. The following Terms of Service (the “Terms of Service”) are a legal contract between you, a student user, a parent or legal guardian, an instructor, or user (collectively, “you” or “your”) and 2Sigma School regarding your use of the service (the “Service”) via our website located at https://alps.2sigma.us, https://alps.2sigma.school, and https://alps.2sigmaschool.org. Throughout the Terms of Service, 2Sigma School may be referred to as “2Sigma School”, “Company”, “we”, “us”, or “our”.

By accessing or using the Service, you signify your agreement to the Terms of Service. If you do not agree to the Terms of Service, you may not access or use the Service. If you are not of legal age to form a binding contract, then your parent or guardian must read these terms and agree to them. If you are a parent or legal guardian and you provide consent for your child to register for the Service, you agree to be bound by these Terms of Service in respect to your or your child’s use of the service.

ACCESS TO THE SERVICE

The 2sigma.school website and domain name and all other websites and domain names affiliated with Company, including any linked pages, content, or applications offered from time to time by Company (collectively, the “Service”) are owned and operated by 2Sigma School.

The Service is an online learning platform for computer science, math, and related subjects. Learners read interactive textbooks, complete and submit coursework, and run code in the browser; educators assign work, review submissions, and track progress. Access is provided through the school, district, or institution that licenses the Service.

RULES OF CONDUCT

The Service is not available to any user previously suspended or barred from it.

Access is provided in one of two ways. Through an institution: a school, district, or institution licenses the Service and creates or authorizes learner accounts, and a learner may use the Service only as that institution has authorized. Learners of any age may be enrolled this way. Directly, where we offer direct registration: a learner aged 13 or older may register themselves. A child under 13 may be registered only by a parent or legal guardian, and we will obtain parental consent, in the manner applicable law requires, before collecting personal information from that child. Because a minor cannot enter into a binding agreement, a learner under 18 who registers directly confirms that a parent or legal guardian has reviewed and agreed to these Terms of Service on their behalf. Additional protections for learners under 13 are described in the Privacy Policy.

By using or registering for the Service, you represent (a) that you have not been previously suspended or barred from the Service; (b) that you are either at least 18 years old, or your parent, guardian, teacher, or school administrator has authorized your use; and (c) that your registration and use of the Service comply with all applicable laws and regulations.

As a user of the Service, you will create a personalized account (an “Account”) which includes a unique username and a password to access the Service and to receive messages from 2Sigma School. You agree to notify us immediately if you become aware of any unauthorized use of your Account. We will not be responsible for any liabilities, losses, or damages arising from or related to any unauthorized use of your Account.

The Service may contain features that allow you to post or provide content, text, code, and other material (“User Content”). You retain all rights in your User Content, and we claim no ownership of it. Where the User Content is student work, the licensing institution holds and controls it as an education record. You grant us only the limited, non-exclusive, royalty-free license needed to host, store, back up, transmit, display, and process User Content in order to operate and support the Service for you, together with any rights you configure through sharing settings. This license exists only to run the Service and ends when the User Content is deleted, except for copies retained in routine backups until they expire.

De-identified data. We may create de-identified data from User Content and platform activity, including submitted coursework, and may use it to operate, secure, evaluate, and improve the Service — including to develop, train, and evaluate the machine-learning models that power it — and to conduct educational research. We may also share de-identified data for educational research, and only under a written agreement that limits its use to the stated research purpose, prohibits re-identification and onward disclosure, and requires deletion when the research concludes. De-identified data is data from which direct and indirect identifiers have been removed such that it cannot reasonably be used to identify a learner, or an educator. We will not attempt to re-identify it, will not permit any recipient to do so, will not sell it, and will not use it for advertising. Sharing de-identified data for educational research under the written agreement described above is not a sale. We will not publish or disclose it in any form that could reasonably identify a learner, an educator, or a group small enough to reveal an individual. This right survives termination in de-identified form only; identified User Content is handled under the retention terms in the Privacy Policy.

ACCEPTABLE USE POLICY

You agree not to use the Service in any way, provide User Content or engage in any conduct that:

  • is unlawful, illegal or unauthorized;
  • is defamatory of any other person;
  • is obscene, sexually explicit or offensive;
  • advertises or promote any other product or business;
  • is likely to harass, upset, embarrass, alarm or annoy any other person;
  • is likely to disrupt our service in any way; or promotes discrimination based on race, sex, religion, nationality, disability, sexual orientation or age;
  • infringes any copyright, trademark, trade secret, privacy, publicity or other proprietary right of any other person; or
  • advocates, promotes or assists any violence or any unlawful act.

We reserve the right, but do not have the obligation, at our sole discretion to edit, delete, remove or block any User Content or terminate access to any user of the Service that violates these Terms of Service, including without limitation this Acceptable Use Policy.

INTERACTIONS

The Service records learner and educator activity and submitted work (“Interactions”) so that it can grade work, report progress, provide support, diagnose faults, and secure the Service. We restrict access to Interactions to personnel and contractors who need it for those purposes and who are bound by confidentiality obligations. Beyond those purposes, we use Interactions for quality measurement and educational research only in de-identified form, subject to the limits in the De-identified data paragraph above.

PRIVACY

Personal information that you provide or that we collect in connection with the Service will be subject to the ALPS by 2Sigma privacy policy, which you acknowledge and accept.

ONLINE CONTENT DISCLAIMER

Though 2Sigma School strives to enforce these Terms of Service for all users, you may nonetheless be exposed to User Content that is inaccurate or objectionable. We may, but have no obligation to, monitor the materials posted in the public areas of the Service and to limit or deny a user's access to the Service, notify law enforcement, or take other applicable action if a user violates these Terms of Service or engages in any activity that violates the rights of any person or entity or is, as determined in our sole discretion, unlawful, offensive, abusive, harmful, or malicious. To the extent the Service offers a feature to communicate with other users, messages sent between users that are not readily accessible to the general public will be treated by us as private to the extent required by applicable law, but may otherwise be accessed, viewed, copied, stored, forwarded, and displayed by us as may be reasonably necessary to enforce these Terms of Service or in compliance with applicable law. Unauthorized use of the Service may result in criminal and/or civil prosecution under federal, state and local law or applicable regulations. If you become aware of misuse of our Service, please contact us at abuse@2sigma.school.

THIRD PARTY WEBSITES
