By using Number Sense, families agree to use the app for personal educational purposes and to follow the rules of the App Store or Google Play account used to install it.

Core learning features are free. Premium is an optional auto-renewing subscription that unlocks the features described on the purchase screen. The store displays the price and billing period before purchase. Subscriptions renew automatically unless canceled through the store account before the current period ends. Canceling stops future renewal and does not remove access already paid for.

Restore Purchases can recover an active subscription for the same store account. Availability may depend on store service, device compatibility, and internet access. Learning progress and rewards have no cash value.

Number Sense does not guarantee a particular academic result and is not a substitute for a learner's school, teacher, or professional advice. Do not misuse connected features or attempt to bypass safety, consent, or subscription controls.

Questions about these terms can be sent to support@mindmath.org.
