Terms of Use

Last updated: 12 November 2026

These Terms of Use apply to the WeJons app and the website wejons.com. Both are provided by Leong Yu Trading Pte. Ltd., a company registered in Singapore ("we", "us"). "You" means the parent or guardian who sets up or allows the use of WeJons, and anyone using the website.

Accepting these terms

By using the WeJons app or our website, you agree to these terms. If you do not agree, please do not use them. Our Privacy Policy explains how we handle personal data.

What WeJons is for

WeJons is a maths learning app for Singapore Primary 3 to 6 pupils, with topics that follow the MOE 2021 Primary Mathematics syllabus. It is a learning aid for practice at home. It does not replace school lessons or teachers.

Beta version

WeJons is currently in beta. This means features and content may change, be added or be removed, and there may be mistakes or bugs, including in questions and answers. If you spot a problem, please tell us at support@wejons.com so we can fix it.

Children and parents

WeJons is made for children, but a child may use it only with the consent of a parent or guardian, who should supervise their use. As the parent or guardian, you are responsible for:

  • deciding whether and how your child uses WeJons;
  • keeping the parent PIN private;
  • the device on which the app is installed.

Acceptable use

You may use WeJons for your family's personal, non-commercial learning. Please do not:

  • copy, sell, share or publish the app's questions, explanations, pictures or sounds;
  • modify, decompile or reverse engineer the app, except where the law allows it;
  • try to break, overload or get around the security of the app or the website;
  • use the app or the website in any unlawful way.

Intellectual property

The WeJons name and logo, the otter mascot, and all questions, explanations, graphics and sounds in the app and on the website belong to Leong Yu Trading Pte. Ltd. They are protected by copyright and other laws. Using WeJons does not give you any ownership of them. You may not use them without our written permission, except as these terms allow.

Disclaimer and limitation of liability

We work hard to make WeJons accurate and helpful, but we provide the app and the website "as is" and "as available". To the extent permitted by law, we do not promise that they will always be available, free of errors, or suitable for a particular purpose, and we do not guarantee any particular learning or exam results.

To the extent permitted by law, we are not liable for any indirect or consequential loss arising from your use of WeJons, or for any loss of data stored on your device. Nothing in these terms limits any liability that cannot be limited under Singapore law.

Changes to the service

We may change, suspend or stop the app or the website, or any part of them, at any time. If we add paid features in the future, payments will be handled by the Apple App Store or Google Play under their own terms.

Changes to these terms

We may update these terms from time to time. When we do, we will change the "Last updated" date at the top of this page. If you continue to use WeJons after a change, you accept the updated terms.

Governing law

These terms are governed by the laws of Singapore. The courts of Singapore have jurisdiction over any dispute arising from them.
