Terms of service

These Terms of service (“Terms”) are an agreement between you and Lê Công Hoan, an individual based in Vietnam (“Puchi”, “we”, “us”), operator of the Puchi mobile and web apps, the website at puchi.io.vn and related services (together, the “Service”). By creating an account, starting as a guest, or otherwise using the Service, you agree to these Terms. If you do not agree, please do not use the Service.

1. Who can use Puchi

You must be old enough to form a binding contract where you live. If you are under 16, you may use the Service only with the consent and supervision of a parent or guardian, who is responsible for your use. We do not knowingly offer the Service to children under 13. If you believe a child has signed up in breach of this rule, please contact us.

2. Accounts

• Guest. You can start without an account. A guest account is tied to your device and may be lost if you delete the app or clear its data.
• Registered account. You can sign in with a one-time code sent to your email address, or with a social account where that option is offered (for example Google). You must give an email address you control, keep your sign-in secure, and tell us if you think someone else has accessed your account.
• Converting a guest. When you register, your guest progress is attached to your account.
• You are responsible for activity on your account. Do not share, sell or transfer it.

3. The Service

Puchi provides Vietnamese language lessons, exercises, audio, stories and review tools. We work to keep the Service accurate and available, but we may add, change or remove features, content or the free plan limits at any time. Some features need an internet connection. We may release updates and may require a minimum app version to keep the Service working safely.

Puchi is an educational tool. It does not provide a qualification, certification or professional translation, and content — including synthetic voices and AI-assisted material — can contain mistakes. Please tell us if you find one.

4. Free plan, Premium and gift codes

• Puchi has a free plan with daily limits. Premium removes or raises some limits.
• At present there are no payments in the Service. Premium is unlocked by redeeming a gift code in the app. Gift codes have no cash value, cannot be exchanged for money, may be limited to one redemption per person, and may expire. Premium obtained from a code lasts for the period stated for that code.
• Do not sell, publish, guess or generate gift codes. We may deactivate codes and revoke Premium obtained through misuse or error.
• If we introduce paid subscriptions, we will publish the price, billing, renewal and refund terms before you are charged, and update these Terms.

5. Acceptable use

You agree to follow our Community guidelines and not to: break the law; interfere with, overload or attempt to gain unauthorised access to the Service; scrape or bulk-download content; use bots or automation to gain XP, streaks or Premium; reverse engineer the apps except where the law allows; or use the Service to harm others.

6. Content and intellectual property

The Service, including its lessons, text, audio, illustrations, the Puchi mascot and logo, and software, belongs to us or our licensors and is protected by law. We give you a personal, non-exclusive, non-transferable, revocable licence to use the Service for your own learning. You may not copy, redistribute, sell or use it to train other products without our written permission. Third-party components are credited on the Attribution page and remain under their own licences.

If you send us feedback or suggestions, you allow us to use them to improve the Service without obligation to you.

7. Your data

How we collect and use personal data is described in our Privacy policy.

8. Suspension and termination

You may stop using the Service and delete your account at any time (see the Help page). We may suspend or close your account, or restrict features, if you breach these Terms or the Community guidelines, if required by law, or to protect the Service or other people. We will normally tell you why unless the law or safety prevents us. When an account ends, your right to use the Service ends; sections that by their nature should continue (such as 6, 9, 10 and 12) continue.

9. Disclaimers

To the extent the law allows, the Service is provided “as is” and “as available”, without warranties of any kind, including fitness for a particular purpose, uninterrupted or error-free operation, or that content is free of mistakes. Nothing in these Terms limits rights you have under mandatory consumer-protection law.

10. Limitation of liability

To the extent the law allows, we are not liable for indirect, incidental or consequential loss, or for loss of data, profit or goodwill, arising from your use of the Service. Our total liability for any claim relating to the Service is limited to the greater of the amount you paid us in the 12 months before the claim (currently none) and US$50 (or the equivalent in Vietnamese dong). Nothing in these Terms excludes liability that cannot be excluded by law, such as for fraud or wilful misconduct.

11. Changes to these Terms

We may update these Terms. For material changes we will give reasonable notice, for example in the app or by email, before they take effect. If you keep using the Service after the change takes effect, you accept the updated Terms; if you do not, please stop using the Service and delete your account.

12. Governing law and disputes

These Terms are governed by the laws of Vietnam. Please contact us first so we can try to resolve any dispute informally. If that does not work, the competent courts in Hanoi, Vietnam have jurisdiction, without affecting any mandatory rights you have as a consumer where you live.
