Family terms

These terms describe the Mathnatic test release. A parent or guardian must control every account and all purchases.

Playing Mathnatic

Anonymous play is available without an account. Parent accounts may create child profiles, choose games, set play time, and review progress. Parents are responsible for supervising use and keeping account and PIN access private.

Plans

Free Family includes selected games and one child profile. Local Family is a one-time entitlement for premium games and parent features; progress remains separate on each device unless a parent exports and imports it. Cloud Family is a monthly subscription that adds automatic progress syncing. Six successful Cloud Family monthly payments permanently earn Local Family. Complimentary Lifetime can be granted by the Mathnatic owner without payment.

Test billing

Stripe is currently connected in test mode. Test checkout does not buy a live entitlement and must not be treated as a real charge. Live billing will not begin until pricing, refunds, taxes, regional availability, cancellation, privacy, and support procedures are finalized.

Cloud cancellation

A scheduled cancellation takes effect at the end of the paid period. Cloud data then remains read-only for 30 days. The parent can keep a local copy or delete the cloud copy sooner. After the retention window, child profiles and progress are scheduled for deletion.

Backups

Local Family backups are encrypted with a password chosen by the parent. Mathnatic cannot recover that password. Parents should keep their backup file and password secure.

Fair use

Do not attempt to disrupt the service, access another family's data, bypass paid access, submit harmful material, or use Mathnatic in a way that violates law. Game suggestions may be declined and do not transfer ownership of an idea or guarantee development.

Changes and availability

Games and free or premium classifications may change as the library grows. Existing paid entitlements will be handled according to the plan terms in effect when live billing begins. Test features may change or be unavailable while they are being validated.
