Terms of Service

Agreement and eligibility

These Terms govern your use of the Chivoc app, website, and related services. By creating an account or using Chivoc, you agree to these Terms. You must be legally able to enter this agreement. If local law requires parental or guardian consent, you may use Chivoc only with that consent.

Accounts

You must provide accurate account information, protect your password and device, and promptly notify us of suspected unauthorized use. One person may use multiple supported sign-in methods linked to the same Chivoc account. You are responsible for activity performed through your account unless applicable law provides otherwise.

License and acceptable use

Chivoc grants you a limited, personal, non-exclusive, non-transferable, revocable license to use the service for lawful personal learning.

You may not copy or resell substantial parts of the service, bypass access controls, scrape content at scale, interfere with operation, introduce malicious code, misuse another person's account, or use Chivoc in a way that violates law or third-party rights.

Learning content

Chivoc provides vocabulary, translations, pronunciation, examples, exercises, and progress tools for educational purposes. Language can vary by context, and machine-assisted content may contain errors. Chivoc does not guarantee any examination score, certification, or specific learning outcome.

HSK names and related marks belong to their respective owners. Chivoc is an independent learning product and is not endorsed by or affiliated with the official HSK examination authorities unless expressly stated.

Purchases and subscriptions

Paid products may include subscriptions or one-time access offers. Price, billing period, renewal terms, and included features will be shown before purchase. Apple App Store or Google Play processes mobile payments and applies its payment, cancellation, and refund rules.

A "lifetime" offer means access to the features described at purchase for as long as Chivoc continues to make that product available and the account remains in good standing. It does not promise that every future product or service will be included, and mandatory consumer rights remain unaffected.

Service changes

We may improve, add, remove, or discontinue features, vocabulary, language support, or technical infrastructure. We will provide reasonable notice when a material change adversely affects a paid service, where feasible and required by law. Temporary interruptions may occur for maintenance, security, or events beyond our control.

Intellectual property

Chivoc, its software, interface, branding, original content, and related rights are owned by Chivoc or its licensors. These Terms do not transfer ownership. Feedback may be used to improve Chivoc without an obligation to compensate you, while personal information remains governed by the Privacy Policy.

Suspension and account deletion

You may stop using Chivoc and delete your account through the app. We may restrict or suspend access when reasonably necessary to protect users, investigate fraud or security issues, enforce these Terms, or comply with law. Where appropriate, we will provide notice and an opportunity to appeal by contacting us.

Disclaimers and liability

To the extent permitted by law, Chivoc is provided on an "as is" and "as available" basis without warranties not expressly stated here. We do not warrant uninterrupted or error-free operation.

Chivoc is not liable for indirect, incidental, special, consequential, or punitive loss to the extent such exclusions are permitted. Nothing in these Terms excludes liability or remedies that cannot legally be excluded, including mandatory consumer protections.

Law, changes, and contact

These Terms are governed by laws applicable to the Chivoc operator, while any mandatory rights available in your country remain unaffected. We may update these Terms as the service changes. Material updates will be communicated appropriately, and continued use after the effective date constitutes acceptance where permitted by law.
