Terms of Service

Last updated: June 6, 2026

Effective date: June 6, 2026

1. Agreement to Terms

By accessing or using TingWo (聽我) at https://tingwo.app (the "Service"), you agree to be bound by these Terms of Service and our Privacy Policy. If you do not agree, do not use the Service.

Before continuing, please also review our Privacy Policy.

TingWo is operated by Codoha Ltd. ("Codoha," "we," "our," or "us").

2. Description of the Service

TingWo turns Chinese text you paste or photograph into a personalized, spoken-first spaced-repetition vocabulary trainer. It identifies likely-new vocabulary, lets you build and review word lists on a spaced-repetition schedule, generates example sentences and audio, and provides Speaking practice in which you record and compare your pronunciation on your own device. AI-powered features rely on external AI providers as described in our Privacy Policy.

3. Your Account

The Service creates an anonymous account for you automatically so your progress can be saved. You may optionally sign in with an email address to make your account persistent across devices. You are responsible for activity that occurs under your account and for maintaining the security of any credentials you use.

4. Fees

The Service is currently provided free of charge. We may introduce paid plans or features in the future; if we do, we will present pricing and terms before you are charged, and continued use of any paid feature will be subject to those terms.

5. Acceptable Use

You agree not to use the Service to:

Violate any applicable law or regulation.
Infringe the intellectual property or other rights of others.
Submit, paste, photograph, or process content that is unlawful, harmful,

abusive, defamatory, obscene, hateful, or otherwise objectionable.

Process content that you do not have the necessary rights, licenses, or

permissions to use.

Submit sensitive personal information (such as government identifiers, financial,

health, or login credentials) to AI-powered features.

Misuse, overload, or attempt to circumvent rate limits or other protections of

the Service.

Reverse engineer, decompile, scrape, or attempt to gain unauthorized access to

any part of the Service or its underlying systems.

Violate the acceptable-use or prohibited-use policies of our AI providers,

including Google's Generative AI Prohibited Use Policy.

6. AI-Generated Content

The Service uses AI to produce vocabulary analysis, phonetics (such as pinyin and zhuyin), translations, example sentences, and synthesized audio. AI output may be inaccurate, incomplete, or unsuitable for your purpose. TingWo is a learning aid, not a professional translation, certification, or educational service. Verify important information independently before relying on it.

7. Intellectual Property

The Service and its original content, features, and functionality are and remain the exclusive property of Codoha Ltd. and its licensors.

You retain ownership of the Content you submit. By using features that process your Content, you grant Codoha and the sub-processors necessary to operate those features a worldwide, non-exclusive, royalty-free license to host, store, reproduce, process, and transmit your Content solely to operate, provide, and improve the specific features you use. You are solely responsible for your Content and represent that you have the rights necessary to submit it.

8. Limitation of Liability

To the maximum extent permitted by law, Codoha Ltd. and its affiliates, agents, directors, employees, suppliers, and licensors shall not be liable for any indirect, punitive, incidental, special, consequential, or exemplary damages, including loss of profits, goodwill, use, or data, arising from your use of or inability to use the Service.

The Service is provided "AS IS" and "AS AVAILABLE," without warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement.

In no event shall Codoha Ltd.'s total liability exceed the amount you paid, if any, for the Service, or USD 10, whichever is less.

9. Disclaimer

Your use of the Service is at your sole risk. The Service depends on third-party services, including Supabase, Vercel, and OpenRouter (which routes to Google Gemini). We do not guarantee that these services, or the Service itself, will always be available, uninterrupted, secure, or error-free.

10. Indemnification

You agree to defend, indemnify, and hold harmless Codoha Ltd. and its officers, directors, employees, contractors, agents, and licensors from any claims, damages, losses, liabilities, costs, and expenses arising from your use of the Service, the Content you process, or your breach of these Terms.

11. Termination

We may suspend or terminate your access to the Service at any time, without prior notice or liability, for any reason, including breach of these Terms. Upon termination, your right to use the Service ceases immediately.

12. Changes to These Terms

We may modify these Terms from time to time. We will post the updated Terms on this page and revise the "Last updated" date above, and will provide notice of material changes where appropriate. Continued use of the Service after changes take effect constitutes acceptance of the revised Terms.

13. Governing Law and Jurisdiction

These Terms are governed by the laws of the Republic of China (Taiwan), without regard to conflict-of-law provisions. You agree to submit to the exclusive jurisdiction of the Hualien District Court, Taiwan, for any disputes arising from these Terms or the Service.

14. General

These Terms constitute the entire agreement between you and Codoha regarding the Service and supersede any prior agreements. If any provision is held unenforceable or invalid, it will be modified to the minimum extent necessary, and the remaining provisions will remain in effect. Our failure to enforce any right or provision is not a waiver of that right or provision.
