Privacy Policy

Effective Date: March 23, 2026

1. Introduction

Hanzicue is designed to help learners understand real Chinese through AI-generated breakdowns. This Privacy Policy explains what information we process, how we use it, and what choices you have when using the product.

If you do not agree with this policy, you should not use the service.

2. Information We Collect

We process the text you submit, any optional context you provide, and limited technical information needed to operate the service.

  • Submitted Chinese text and optional context
  • Anonymous usage cookies used for daily free-limit enforcement
  • Basic request metadata needed for security, reliability, and debugging

3. How We Use Your Information

We use collected information to run and improve Hanzicue.

  • Generate breakdowns through third-party AI providers
  • Render your most recent live result page
  • Enforce anonymous daily usage limits
  • Monitor failures, abuse, and service reliability

4. How We Share Information

We do not sell personal information. We may share limited data with service providers only when needed to operate Hanzicue.

  • AI providers that process submitted text to generate analysis
  • Infrastructure providers that host or deliver the application
  • Legal or security disclosures when required by law or necessary to protect the service

5. Cookies and Local Usage Limits

Hanzicue currently uses browser cookies to track anonymous daily free usage. These cookies are not tied to a user account in the current version.

6. Data Retention

This version of Hanzicue does not use a user database. Some recent live breakdown data may be stored temporarily on the server runtime so the current breakdown page can render correctly.

We may clear temporary runtime data at any time as part of normal operation or deployment.

7. Security

We use reasonable technical measures to protect the service, but no system is completely secure. You should avoid submitting highly sensitive personal information.

8. Your Choices

You can stop using the service at any time, clear browser cookies to remove anonymous usage data stored on your device, and avoid submitting information you do not want processed by AI providers.

9. Changes to This Policy

We may update this Privacy Policy as Hanzicue evolves. Material changes will be reflected by updating the effective date on this page.

If you have privacy questions about Hanzicue, contact the team through the product contact channel before using the service for sensitive workflows.
