Ngiemboon Terms of Service

1. Accounts

You are responsible for access to your sign-in method and for providing accurate account information. Do not attempt to access another user's account or administrative systems without authorization.

2. Learning content

The app provides educational language-learning content and interactive practice. Content may be corrected, expanded, reordered, or removed as the language corpus and courses evolve.

3. Virtual coins and welcome bonus

Coins are virtual application units used only within Ngiemboon. They are not money, stored value, cryptocurrency, or a bank balance; they cannot be transferred between users or redeemed for cash.

Eligible new Google identities may receive a one-time 30-coin welcome bonus. Deleting and recreating an account does not create a new entitlement to that bonus. We may use a minimal pseudonymous anti-abuse marker to enforce this rule.

Some access obtained with coins may be limited by the terms shown in the app, including time-limited access where a feature is explicitly presented that way.

4. Google Play purchases

Digital coin purchases offered in the Android app are processed through Google Play Billing. Pricing, taxes, payment methods, order handling, and applicable refund mechanisms may depend on Google Play and your country. If a verified purchase is not credited correctly, contact support with the Google Play order ID.

See Purchases & Refunds.

5. Rewarded features and ads

Where offered, rewarded ads or similar features may provide virtual coins after qualifying completion. Attempting to automate, falsify, manipulate, or repeatedly exploit reward mechanisms may result in rewards being denied or account access being restricted.

6. Acceptable use

You may not interfere with the service, bypass access controls, abuse purchase or reward systems, scrape private interfaces, introduce malicious code, or use the service in a way that violates applicable law or the rights of others.

7. Intellectual property

The app interface, original course structure, software, graphics, and original learning materials are protected by applicable intellectual-property rules. Language facts and words themselves are not claimed as proprietary merely because they appear in the app.

8. Account suspension or deletion

You may request permanent deletion at any time. We may restrict access where reasonably necessary for security, abuse prevention, legal compliance, or serious violations of these terms. Account deletion is handled as described in our Privacy Policy and Account Deletion page.

9. Availability and disclaimers

We work to keep the service available and accurate, but uninterrupted operation is not guaranteed. Educational content may contain errors and should be treated as a learning aid rather than professional, legal, medical, or financial advice.
