Terms of Service

By accessing or using Chamelingo ("the Service"), you agree to be bound by these Terms of Service. If you do not agree to these terms, do not use the Service.

Chamelingo is a gamified Korean language learning platform. The Service includes web-based lessons, multiplayer arena mode, flashcards, exam preparation, and vocabulary analytics. Content follows a structured beginner-to-intermediate curriculum.

You may use certain features as a guest without creating an account. To access the full Service, you must register with a valid email address. You are responsible for maintaining the security of your account credentials.

Chamelingo offers paid subscription plans billed monthly or annually through our payment processor. In the iOS app, subscriptions are billed through your Apple ID (Settings → Apple ID → Subscriptions). In the Android app, subscriptions are billed through Google Play (Google Play → Payments & subscriptions). You may cancel at any time; cancellation takes effect at the end of the current billing period.

For refund eligibility and instructions, see our Refund Policy. Apple and Google purchases may be governed by the store's rules and may need to be requested through that store.

You agree not to:

• Use the Service for any unlawful purpose
• Attempt to gain unauthorized access to any part of the Service
• Interfere with or disrupt the Service or its servers
• Use automated means to access the Service without permission
• Harass, abuse, or harm other users

Automated access is permitted only through Chamelingo APIs and resources that we expressly designate as public or crawlable, and only in accordance with the applicable documentation, API-key scopes, quotas, and rate limits. You may not use bots, scrapers, crawlers, or similar automated means to access other parts of the Service; harvest, bulk-copy, or republish Service content or data except as expressly permitted by us or applicable law; bypass authentication, rate limits, paid-feature restrictions, or account controls; or share, sell, or misuse API keys. We may rate-limit, suspend, or revoke access or API keys for violations.

You retain ownership of material you submit to the Service, including custom decks, study notes, and documents. You represent that you have all rights and permissions needed to submit it and that it does not violate the law or third-party rights. You grant us a limited, non-exclusive license to host, process, and transform the material as necessary to provide and maintain the Service, for example to generate lessons and exercises and make them available to you as described in the Service. We do not claim ownership of your material.

AI-generated feedback, translations, explanations, and exercises are provided for general educational purposes and may be inaccurate, incomplete, or unsuitable for your circumstances. They are not legal, medical, immigration, financial, official examination, or other professional advice and should not replace official sources, qualified professionals, or test organizers. You are responsible for reviewing material that you choose to use.

All content, design, and code of the Service are the property of Chamelingo or used under license for educational purposes. You may not reproduce, distribute, or create derivative works from the Service without permission.

The Service is provided "as is" without warranties of any kind. We do not guarantee uninterrupted access or that the Service will be error-free.

Chamelingo shall not be liable for any indirect, incidental, or consequential damages arising from your use of the Service.

We reserve the right to modify these terms at any time. Continued use of the Service after changes constitutes acceptance of the updated terms.
