Terms of use

AMP Mathematics is a learning service from Corpora Inc. These terms cover the Corpora website, AMP practice, and materials supplied with a license.

Who may purchase

A parent or legal guardian must manage the account, purchase access, and complete the applicable consent process before creating a child’s learning profile. Keep sign-in details private. Use a learner nickname rather than a full legal name.

What a license includes

A license provides one learner with the app and the printable materials offered with that plan for its stated term. You may print materials for that learner’s personal education. You may not resell materials, share account access outside your family, or redistribute the materials publicly.

Price, term, and renewal

The checkout shows the price, currency, taxes, access period, and whether the selected plan renews. An automatically renewing subscription continues until cancelled. Manage cancellation in the parent account’s billing portal. Cancelling stops future renewal; a refund is a separate request under the refund policy. Education-fund purchases follow the approved program route and stated term.

Learning and availability

AMP offers the skills listed in its coverage description. Placement is an estimate from a limited set of answers, not a diagnosis, accredited qualification, or guaranteed score. We do not promise complete grade-level coverage or a particular rate of progress. Internet access and a supported modern browser are required for the web service.

Responsible use

Do not attempt unauthorized access, interfere with the service, automate abusive requests, or upload material you do not have permission to use. We may restrict access to protect accounts or the service. Contact support if you believe a restriction is mistaken.

Problems and changes

Report incorrect content or a service problem to support@corpora.inc. We may update features and these terms. Material changes will be explained before they apply to an existing purchase where required. Nothing in these terms removes rights that applicable consumer law gives you.
