Terms of Service

These Terms of Service (“Terms”) govern your use of the Koala Chinese 樹熊認字 mobile application, also published as “Koala Learning – Learn Chinese” (the “App”), provided by Keiko-Lab (“we”, “us”, or “our”).

Effective date: 25 October 2026

1. Eligibility and Parental Use

The App is intended for family and educational use. It is designed primarily for children under the supervision of a parent, guardian, teacher, or other authorized adult, but it may also be used by parents, guardians, teachers, and adult learners. If you are a parent or guardian, you are responsible for:

  • supervising a child’s use of the App
  • decisions about enabling subscriptions, notifications, camera use, or sync
  • any information entered into the App, including child profile names
  • creating and keeping secure any family account, and keeping its email address accurate

2. License

Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to use the App for personal, non-commercial family or educational use on devices you own or control (Apple-branded devices for the iOS app and Android devices for the Android app), in accordance with the usage rules of the app store you downloaded it from. We reserve all rights not expressly granted.

3. App Features

The App provides educational games and learning tools related to Chinese characters, vocabulary, pronunciation, and related progress tracking. Some features may be free, while others may require an active subscription. Pronunciation and speech depend on the voices installed on your device and may vary between devices.

4. Family Account and Sync

You can use the App without an account. A parent or guardian may optionally create a family account, using an email address and a one-time code, to sync progress across devices. Syncing is a premium feature. You can sign out at any time, and you can delete the account in the App or by contacting us, as described on our Delete Account page. Deleting the account removes the data we store for it, but does not cancel a subscription.

5. Subscriptions and Billing

The App may offer auto-renewable subscriptions, including monthly and annual premium plans.

If you purchase a subscription:

  • payment is charged through your Google Play account (Android) or your Apple account (iOS)
  • subscriptions renew automatically unless canceled before the end of the current billing period (at least 24 hours before, for Apple subscriptions)
  • your account may be charged for renewal shortly before the end of the current billing period
  • subscription pricing may vary by country, currency, promotional offer, and store
  • you can manage or cancel subscriptions in Google Play (Payments & subscriptions, then Subscriptions) or in your Apple account settings
  • refunds are handled by Google or Apple under their own policies

If a free trial or introductory offer is made available, any unused portion may be forfeited when you purchase a subscription, where permitted by law and by the store’s rules.

6. Restore Purchases

If you previously purchased an eligible subscription through the same Google Play or Apple account, you may use the App’s restore purchases feature or the store’s systems to restore access, subject to the store’s verification and the subscription remaining active.

7. No Unlawful or Misuse Conduct

You agree not to:

  • misuse the App or interfere with its operation
  • attempt to reverse engineer, decompile, or extract source code except where prohibited by applicable law from restricting that right
  • use the App in a way that violates applicable law or the rights of others
  • bypass the parent check or purchase protections
  • use the camera feature to photograph people without their permission, or to photograph material you have no right to copy

8. Third-Party Services

Certain App features rely on services we do not control: Google Play (billing and subscriptions), Apple (App Store billing, notifications, and iCloud/CloudKit), Google ML Kit and your device’s speech engine, and Supabase, which hosts our optional sync service. Those services are controlled by their providers and may be subject to separate terms, availability limits, and privacy practices. We are not responsible for outages, restrictions, or changes in third-party services.

9. Educational Purpose Only

The App is provided for educational and entertainment purposes only. We do not guarantee specific learning outcomes, fluency, academic performance, correct recognition of text in photos, or uninterrupted access.

10. Intellectual Property

The App, including its software, text, graphics, illustrations, interface design, audio arrangements, trademarks, and other content, is owned by us or our licensors and is protected by applicable intellectual property laws. You may not copy, modify, distribute, sell, or create derivative works from the App except as expressly permitted by law or with our prior written permission.

11. Privacy

Your use of the App is also governed by our Privacy Policy.

12. Availability and Changes

We may update, modify, suspend, or discontinue all or part of the App at any time, including adding, removing, or changing features, content, or pricing. We are not liable if any part of the App is unavailable at any time.

13. Disclaimer of Warranties

To the maximum extent permitted by law, the App is provided “as is” and “as available,” without warranties of any kind, whether express, implied, or statutory, including implied warranties of merchantability, fitness for a particular purpose, title, and non-infringement. We do not warrant that the App will be uninterrupted, error-free, secure, or free from harmful components.

14. Limitation of Liability

To the maximum extent permitted by law, Keiko-Lab and its affiliates, licensors, and service providers will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or any loss of data, revenue, profits, or goodwill arising out of or related to your use of the App. To the maximum extent permitted by law, our total liability for any claim relating to the App will not exceed the amount you paid, if any, for the App or subscription during the twelve months before the event giving rise to the claim. Some jurisdictions do not allow certain limitations, so some of the above may not apply to you.

15. Termination

These Terms remain in effect until terminated. We may suspend or terminate access to the App or to a family account if you materially violate these Terms. You may stop using the App at any time by discontinuing use and uninstalling it, and you may delete your family account as described above. Sections that by their nature should survive termination will survive, including intellectual property, disclaimers, limitation of liability, and dispute-related provisions.

16. Governing Law

These Terms are governed by the laws of New South Wales, Australia, without regard to conflict of law rules, except to the extent superseded by mandatory consumer protection laws in your place of residence. You submit to the non-exclusive jurisdiction of the courts of New South Wales, Australia. Nothing in these Terms excludes rights you have under the Australian Consumer Law or other mandatory consumer laws that cannot be excluded.

17. Mobile App Terms (Google Play and Apple App Store)

Google Play. If you download the App from Google Play, your use of the App is also subject to the Google Play Terms of Service.

Apple App Store. If you download the App from the Apple App Store, your use of the App is also subject to Apple’s Standard Licensed Application End User License Agreement (EULA), which you can review at https://www.apple.com/legal/internet-services/itunes/dev/stdeula/.

If there is a conflict between these Terms and the store’s terms or Apple’s EULA, the store’s terms or Apple’s EULA will govern with respect to the mobile application.
