Terms of Service

Effective Date: November 16, 2022

Thank you for your interest in using the online services operated by DeltaMath ("DeltaMath", "we" or "us"). These Terms of Service ("Terms" or "Agreement") govern your use of DeltaMath's online services (the "Services"). Please continue reading to learn about the terms by which you may use our Services.

These Terms apply to all schools, school districts, or teachers (collectively referred to as "Schools") as well as students and parents, who use the Services; (collectively along with "Schools" referred to as “Users” or “you”).

Any material change to these policies will be announced via a banner message displayed on this website.

By accessing or using the Services, creating an account, or by otherwise affirmatively stating your desire to use the Services, you signify that you have read, understood, and agree to be bound by this Agreement and to the collection and use of your information as set forth in the DeltaMath Privacy Policy, otherwise you may not use the Services. Because our Services change relatively often, the terms in this Agreement and our Privacy Policy may change too. Upon making changes, we will update the “Effective Date” found at the top of this page. Your continued use of the Services after any changes constitutes your acceptance of the new terms.

DeltaMath's Service

DeltaMath is an online math practice and learning site. Students will register with a teacher code and complete assignments made by their teacher.

As long as you are complying with all of the terms and conditions of this Agreement, DeltaMath gives you permission to access and use the Service. The Service is available for your personal, noncommercial use. We are constantly changing and improving our Services. We may add or remove functionalities or features, and we may suspend or stop a Service altogether, including, for example, if you do not comply with this Agreement or if we are investigating suspected misconduct. We may also stop providing Service to you, or add or create new limits to our Service or restrict your access to all or part of the Service at any time without notice or liability.

In particular, individual teacher licenses, paid or unpaid, are intended for single-teacher use. We reserve the right to reach out to end-users and/or revoke access in cases where it appears more than one teacher is using an account without our prior consent.

The right to access and use the Service is revoked in jurisdictions where it may be prohibited, if any.

Refund Policy

Refunds for site or individual teacher licenses are available within one month (30 days) of purchase. Full or partial refunds are not available after that time, and in no case will unused licenses roll over to the next school year. Contact orders@deltamath.com to request a refund.

Personal Information and Student Data

The U.S. Children’s Online Privacy and Protection Act (“COPPA”) requires that online service providers obtain verifiable parental consent before collecting personal information from children under 13. If you are a School providing the Service to children under 13 (whether in the U.S. or elsewhere), you represent and warrant that you have received consent from parents, or have the authority to provide consent on behalf of parents, for us to collect information from students before allowing children under 13 to access DeltaMath Services. We recommend that all Schools provide appropriate disclosures to students and parents regarding their use of service providers such as DeltaMath.

When DeltaMath is used by a School for an educational purpose, DeltaMath may collect or have access to Student Data that is provided by the School or by the Student. “Student Data” is personal information that is directly related to an identifiable Student and may include “educational records” as defined by the Family Educational Rights and Privacy Act (“FERPA”), 20 U.S.C. § 1232(g).

Confidentiality. DeltaMath agrees to treat Student Data as confidential and not to share it with third parties other than as described in these Terms, and in our Privacy Policy.

Student Data Access. You authorize DeltaMath to access or collect Student Data for the purpose of providing the Service. In the U.S., DeltaMath shall collect and process Student Data as a School Official with a legitimate educational interest pursuant to FERPA 34 CFR Part 99.31(a)(1).

Personal Information and Student Data Consents and Authority.If you are School User, you represent and warrant that you have provided appropriate disclosures to your School and to parents regarding your sharing such Personal Information with DeltaMath. Both Parties agree to uphold their obligations under the Family Educational Rights and Privacy Act (“FERPA”), the Protection of Pupil Rights Amendment ("PPRA"), and the Children’s Online Privacy and Protection Act (“COPPA”) and applicable State laws relating to student data privacy. DeltaMath relies on each School to obtain and provide appropriate consent and disclosures, if necessary, for DeltaMath to collect any Student Data, including the collection of Student Data directly from students under 13, as permitted under COPPA. You agree to comply with these Terms and all laws and regulations governing the protection of personal information, including children’s information, and the sharing of student education records.

Use of Student Data. By submitting or providing us access to Student Data, you agree that DeltaMath may use the Student Data solely for the purposes of (i) providing the Service, (ii) improving and developing our Service, (iii) enforcing our rights under these Terms, and (iv) as permitted with the School’s or the User’s consent. DeltaMath shall not use Student Data to engage in targeted advertising.

Use of Anonymized Student Data. You agree that we may collect and use data derived from Student Data for our own purposes, such as for product development, research analytics, and marketing our Service, provided that such data will be de-identified and/or aggregated to reasonably avoid identification of a specific individual.

Use of Personal Information for Marketing. You agree that DeltaMath may provide information about new DeltaMath features and offerings to school or district administrative users and teachers from time to time, provided that such advertisements shall not be based on Student Data. For emphasis, and without limitation, DeltaMath shall never use Student Data to engage in targeted advertising, nor shall DeltaMath direct advertising to student users.

Third-Party Service Providers. You acknowledge and agree that DeltaMath may provide access to Student Data to our employees and service providers, which have a legitimate need to access such information in order to provide their services to us. We and our employees, affiliates, service providers, or agents involved in the handling, transmittal, and processing of Student Data will be required to maintain the confidentiality of such data.

Student Data Retention and Deletion Requests.DeltaMath retains Student Data, but for educational purposes only. Oftentimes students will want to refer back to their DeltaMath student accounts for college or other future courses. However, if a student does not utilize their account for a period of two years, their account and personally identifiable information will be deleted. Additionally, Schools may request that we delete Student Data in our possession at any time by providing such a request in writing. We shall respond to the deletion request as soon as possible, but in most instances within 45 days, other than for data stored on backup tapes which shall be deleted in the ordinary course of business. A Parent seeking to modify, correct, or delete personal information in a Student Account that is connected to an active School account will be instructed to contact the School to discuss data deletion or modification. We are not required to delete data that has been derived from Student Data so long as it has been anonymized such that it does not reasonably identify an individual.

d. Exclusions And Limitations. Some jurisdictions do not allow the exclusion of certain warranties or the limitation or exclusion of liability for certain damages. Accordingly, some of the above limitations and disclaimers may not apply to you.

DeltaMath reserves the right, at its own expense, to assume the exclusive defense and control of any matter otherwise subject to indemnification by you, and in such case, you agree to cooperate with DeltaMath's defense of such claim.


This Agreement shall remain in full force and effect while you use the Service. DeltaMath may suspend or terminate your access to the Service or your account at any time, for any reason (without cause or for your violation of any term of this Agreement), and without warning or notice, which may result in the loss of information associated with your account.

All provisions of this Agreement which, by their nature, should survive termination, shall survive termination, including, without limitation, ownership provisions, warranty disclaimers, and limitations of liability.
