Terms of use

1. What Kizupi is

Kizupi is a math tutor for children in Grades 1 to 6, on the web and in the Kizupi app for Fire tablets, available by paid subscription after a free trial (section 3). It is an educational aid and doesn’t replace school, a teacher or a parent’s judgment.

2. Accounts are for grown-ups

• You must be an adult (18 or older, or the age of majority where you live) to create an account.
• You may add up to four children for whom you are the parent or legal guardian, or for whom you have that person’s permission.
• You are responsible for your account, for the devices you set up for your children, and for keeping your email, PIN and passkeys secure.
• Tell us at hello@kizupi.com if you think someone else is using your account.

3. Plans, billing and trials

• Your account. Creating an account and adding children costs nothing. Tutoring sessions need an active Kizupi Family subscription (including its free trial). Without one, lessons are paused, and your account, your children’s profiles and their progress are kept until you delete them.
• Kizupi Family. A subscription for your whole family: tutoring for up to four children. On our website it costs USD 10 a month or USD 60 a year. Prices include any sales tax or VAT that applies, so the amount shown is the amount you pay. Bought through an app store, it costs the price that store shows.
• Free trial. A family’s first Kizupi Family subscription starts with a 7-day free trial. A payment card is needed to start it. You won’t be charged during the trial, and if you cancel before it ends you won’t be charged at all. If you don’t cancel, the first payment is taken when the trial ends. One free trial per family.
• Automatic renewal. The subscription renews automatically at the end of each month or year, at the price then in effect, until you cancel. We email a reminder before a free trial ends.
• Cancelling. You can cancel at any time: a plan bought on our website in the parent area, under Plan → Manage billing; a plan bought through the Amazon Appstore in your Amazon account, under Your Apps & Subscriptions. Your family keeps Kizupi Family until the end of the trial or the period already paid for; then lessons pause. Your children’s profiles and progress are kept.
• Refunds. Payments are non-refundable except where the law requires otherwise or we decide to make an exception; if something went wrong, write to hello@kizupi.com and we will look at it. If you live in the European Union or the United Kingdom, you have a right to withdraw from a purchase within 14 days; by starting the subscription you ask for the service to begin straight away, and a refund may be reduced for the part already provided.
• Price changes. If we change the price of Kizupi Family, we will email the account owner at least 30 days before the new price applies to them, and you can cancel before then.
• Who sells it. On our website, Kizupi Family is sold through our authorized reseller, which acts as the merchant of record: it processes the payment, handles sales tax and VAT, issues the receipt and appears on your card statement. Its own terms of sale also apply to the purchase. We never see or store your full card details.
• Bought through an app store. In the Kizupi app for Fire tablets, Kizupi Family is sold by Amazon through the Amazon Appstore. That store’s terms apply to the purchase, it takes the payment and issues the receipt, and refunds and cancelling go through it. Whichever way your family subscribes, the plan works on every device you sign in on.
• Payments and children. Only the account owner, an adult, can buy or change a plan, from the parent area. Children in Kizupi never see prices or anything to buy, and Kizupi has no ads.
• Failed payments. If a renewal payment fails, we keep Kizupi Family for a few days while it is retried. If it still can’t be collected, the subscription ends and lessons pause.

4. Privacy

How we handle your family’s information is described in the privacy policy, which is part of these terms.

5. Using Kizupi well

Please don’t:

• use Kizupi for anything unlawful, or to harm a child;
• try to break, overload, reverse-engineer or get around the security of the service, or access other families’ data;
• use automated tools to scrape or mass-create accounts;
• copy or resell the lessons, characters or artwork.

6. Your family’s content

Your child’s answers and notebook pages belong to your family. You give us permission to store and use them only to run Kizupi for you, as the privacy policy describes. That permission ends when you delete them.

7. Our content

Kizupi, the owl and the animal buddies, the worlds, lessons, problems, voice lines, sounds and software belong to us or our licensors. You may use them to learn with your family. Please don’t copy or distribute them otherwise.

8. About the teaching

• We check every answer with a math engine and review Kizupi’s lines, but mistakes can still happen. If something looks wrong, tell us.
• Speech recognition, spoken voice and translation are automated and can mishear or misspeak. Captions are always shown so you and your child can check.
• Grades, tracks and suggestions are guidance based on practice in Kizupi, not an official assessment.

9. Changes and availability

We keep improving Kizupi and may add, change or remove features. What changed is listed in the changelog. We aim to keep the service running but can’t promise it will always be available or error-free. If we change these terms in a way that matters, we will email account holders first. Continuing to use Kizupi after that means you accept the new terms.

10. Ending your account

You can delete your account at any time in Settings. Deleting the account also cancels a Kizupi Family subscription, so it won’t renew. We may suspend or close an account that breaks these terms or puts children at risk, and will tell you why unless the law or a child’s safety prevents it. If we ever shut Kizupi down, we will give account holders reasonable notice and a chance to export their data.

11. Disclaimers

Kizupi is provided “as is” and “as available”, without warranties of any kind, to the fullest extent the law allows. Nothing in these terms limits rights you have under consumer laws that can’t be waived.

12. Limitation of liability

To the fullest extent the law allows, we aren’t liable for indirect or consequential losses arising from your use of Kizupi, and our total liability to you for any claim is limited to the greater of the amount you paid for Kizupi in the 12 months before the claim and USD 50. This doesn’t limit liability that can’t be limited by law, such as for fraud or for death or personal injury caused by negligence.
