Terms of use

Numi Isles (the game at play.numinumi.app and this website at numinumi.app) is a maths game for primary school children, run by Out There Studio Pte. Ltd. (UEN 202648096N) in Singapore (“we”, “us”). These terms are the agreement between us and the grown-ups who use it, for themselves and for their kids. By signing in you agree to them.

How we handle personal data is in our Privacy policy.

• Numi Isles is for families. A grown-up account is for an adult (18 or older) who is a parent or guardian, or who looks after a child with their parent’s permission.
• Every kid account belongs to a grown-up, who makes or approves it and is responsible for how it is used. A kid can have up to two grown-ups.
• Kids play with their grown-up’s permission and under their guidance.

Numi Isles is free. There is nothing to buy: shells and other rewards in the game are pretend, with no money value, and cannot be exchanged for anything outside it.

Numi Isles is young and still growing. We provide it “as is” and “as available”: features may change, it may sometimes be unavailable, and we may pause or stop it. We will try to tell you in good time before a big change, and before stopping it.

• Keep sign-in codes, sign-in links, device codes and invites to yourself. Anyone holding one may be able to sign in.
• Approve a kid’s device only when it is in front of you, or you know it is your kid’s.
• You are responsible for what happens in your account and your kids’ accounts. If you think someone else has got in, sign their devices out in the grown-up area and tell us.

Everyone who uses Numi Isles agrees to:

• Be kind. Choose nicknames that are friendly and are not anyone’s full name, and never use the game to upset or pressure another child.
• Only use friend codes that were shared with you, and only invite or approve people you know.
• Not try to get into accounts or data that are not yours, or to get around our security, limits or safety features.
• Not disrupt or overload the service, copy it in bulk, or play with bots, scripts or other automated tools (including to change scores or race results).
• Not use Numi Isles for advertising or any other commercial purpose.

If you see something that worries you, tell us at support@numinumi.app.

Our questions are made by our own software, following the Singapore primary mathematics syllabus. We check them carefully and try hard to make every question, hint and worked answer correct, but mistakes can slip through. If you spot one, please tell us at support@numinumi.app and we will fix it.

Numi Isles is independent. It is not made, endorsed or checked by the Ministry of Education, and it is practice to support learning, not a replacement for school or for a teacher’s advice.

The app, this website, its questions, the Numi characters, the art, music and sounds belong to us. We give you a personal, non-commercial right to use them in Numi Isles while you have an account. If you send us ideas or feedback, we may use them to improve Numi Isles without owing you anything.

• You can stop using Numi Isles at any time. You can delete your kid’s account in her settings and your own in Settings, or ask us to (see the Privacy policy).
• A grown-up can leave a kid’s family when she has another grown-up. The grown-up who sent an invite can remove the grown-up who joined with it.
• We may suspend or close an account that breaks these terms or puts a child at risk. Where we can, we will tell the grown-up first and explain why.
• If we ever stop running Numi Isles, we will tell grown-ups in good time and then delete the personal data we hold.

We work hard to keep Numi Isles running, accurate and safe, but we cannot promise that it will always be available, free of mistakes or right for every child. As far as the law allows, we are not responsible for losses that come from using it, from being unable to use it, or from relying on its content, including lost progress, and we are never responsible for indirect or unforeseeable losses.

Nothing in these terms limits any responsibility that the law does not allow us to limit, such as for death or personal injury caused by our negligence, or for fraud.

These terms are governed by the laws of Singapore, and the courts of Singapore decide any dispute about them. If something goes wrong, please talk to us first: most things can be sorted out quickly.

We may update these terms as Numi Isles grows. We will change the date at the top, and if a change matters we will tell grown-ups clearly in the app before it applies. Using Numi Isles after a change means you accept the new terms.

Questions about these terms, mistakes in a question or anything else: write to support@numinumi.app.
