Terms of use

These terms are an agreement between you and LifeRivo ("we") about your use of LifeRivo. By creating an account or continuing to use the service, you confirm that you have read and accept everything below.

1. The service

LifeRivo is an online learning platform with programming courses (Python, C, C++, Java) and language courses (English, Chinese, Japanese, Korean, French). It includes lessons, auto-graded exercises, tests, listening, speaking and pronunciation practice, AI conversation and mock interviews, an AI tutor, classes, completion certificates and related features. Basic levels are free; advanced levels and some features belong to paid plans (Pro, Family, Teacher) under the Membership rules.

2. Eligibility

You must give truthful registration details. People under 16 may use the service only with the consent and supervision of a parent or guardian; paid plans must be bought by a person with full legal capacity.

3. Accounts

Each account is for one person. You are responsible for keeping your password secret and for all activity on your account. Do not share, sell or rent accounts. Tell us at once if you suspect someone else is using your account.

4. Acceptable use

• Do not use the code runner and grader to attack systems, scan networks, mine cryptocurrency, send spam or overload the service.
• Do not cheat on learning results or try to bypass AI limits, rate limits or the grading system.
• Do not bulk-copy, resell or distribute lessons, exercises or answers.
• Do not post, or send to the AI or a class, content that is unlawful, abusive or harassing.

5. AI features

The AI tutor, conversations, mock interviews and pronunciation tips are generated by third-party AI models. Answers may be inaccurate and are for learning support only; they are not career, legal or medical advice. Mock-interview results do not reflect any organisation's hiring decision. Do not send sensitive personal information to AI features. AI usage is limited according to your plan.

6. Speaking and pronunciation

Speaking practice needs you to allow your browser to use the microphone. Speech is turned into text by your browser's speech-recognition service; we receive only the recognised text in order to score it, and we do not store audio recordings. Pronunciation scores are calculated from the recognised text, so they are indicative only and do not replace assessment by a teacher or an official exam. Model voices may be produced by speech synthesis.

7. Classes

Teachers are responsible for the assignments, tests and feedback in their own classes and may use learner data only for teaching. Learners in a class covered by a teacher licence get Pro access while they are class members and the licence is valid.

8. Certificates

Certificates issued by LifeRivo confirm that you completed content on the platform. They are not degrees, professional certifications or international language certificates (HSK, JLPT, TOPIK, DELF, CEFR-based certificates and so on); the names of those frameworks are used only to describe the level of the content.

9. Paid plans

Payment, activation, duration and refunds follow the Payment policy, the Refund policy and the Membership rules. Plans never renew automatically.

10. Ownership of content

Lessons, exercises, tests, the interface and the software belong to us or our licensors. You may use them for personal learning. Code and work you write yourself belong to you; you allow us to store and process them to provide the service (grading, showing them to the teacher of a class you joined).

11. Suspension and termination

We may suspend or close accounts that break these terms, after telling you why unless urgent action is needed to protect the system. You may stop using the service and ask for your account to be deleted at any time through the contact channel.

12. Limitation of liability

The service is provided as is. We work to keep it stable and back up data regularly, but we do not guarantee uninterrupted or error-free operation. To the extent the law allows, our liability to an account is limited to the amount that account paid in the previous 12 months.

13. Governing law

These terms are governed by the laws of Vietnam. Disputes are first settled by negotiation; failing that, they are resolved by the competent court in Vietnam.

14. Changes to these terms

When we make important changes we announce them on the website or in Notifications before they apply. Continuing to use the service after that means you accept the new terms.
