Terms of Service

Last updated 2026-10-24

Who this is for

Kiwi Math accounts are created and managed by a parent or guardian (18 or older). By creating an account you confirm you're an adult setting this up for your household.

The service

Kiwi Math provides math practice for elementary-age kids: adaptive practice questions, a curated question bank, and progress tracking. A free account includes unlimited adaptive practice (Mixed, by-operation, and Endless modes). A paid subscription unlocks the full curated question bank, weak-spot and review modes, and timed tests.

Subscriptions, billing, and cancellation

• Paid plans are billed monthly and automatically renew each month until you cancel - there is no fixed term and no separate "notice period."
• Adding a kid beyond the first two included adds $1/month per extra kid to your next bill, prorated for the current period.
• Canceling takes no more effort than subscribing did: both are a single flow (Stripe Checkout to subscribe, Stripe's billing portal to cancel), reachable in one click from your Account page. We don't require a phone call, a support ticket, or a "retention" conversation to cancel.
• Canceling stops future renewals; you keep access through the end of the period you already paid for. We don't currently send a reminder before each month's renewal - if you'd like one, email us and we'll add it manually for your account until that's automated.

Acceptable use

Don't use Kiwi Math to try to access another family's data, disrupt the service, or resell access. Each subscription is for one household's kids.

Content

Practice questions are either drawn from our own curated bank or generated by a deterministic practice algorithm (not a generative AI model - see our Privacy Policy for detail). We try to keep every question accurate; if you spot one that isn't, use the "flag" link next to it in the app and we'll review it.

No warranty

Kiwi Math is provided "as is." We work to keep it accurate and available, but we don't guarantee it will be error-free or uninterrupted.

Changes

We may update these terms as the product changes; we'll update the date at the top of this page when we do.
