Privacy Policy

This Privacy Policy explains how Mandarin Ladder ("we", "us", or "our") collects, uses, and safeguards information when you use our website and learning platform (the "Service"). By using the Service, you agree to the practices described here.

1. Information We Collect

• Account information. When you create an account, we collect your email address and a password (stored only as a secure hash).
• Learning data. We store your assessment results, such as scores and proficiency levels, linked to your account so we can show your progress.
• Usage analytics. We collect aggregated, non-identifying analytics about how visitors interact with the Service (e.g., pages viewed, device type) to improve the product.
• Technical data. Standard server logs (IP address, browser type, timestamps) are recorded for security and reliability.

2. How We Use Your Information

• To provide, maintain, and improve the Service.
• To authenticate you and keep your account secure.
• To save and display your assessment results and learning progress.
• To send essential account-related emails (e.g., verification, password reset).
• To understand usage patterns and improve content and features.

3. Sharing of Information

We do not sell your personal information to third parties. We may share limited data with trusted service providers (such as hosting, authentication, and analytics vendors) strictly to operate the Service, and only under confidentiality and data-protection obligations. We may also disclose information if required by law.

4. Data Storage and Security

Account and learning data are stored with our backend provider using industry-standard security practices, including encryption in transit. While no system is perfectly secure, we work to protect your data against unauthorized access, alteration, or disclosure.

5. Cookies and Analytics

We use cookies and similar technologies to keep you signed in and to measure anonymous usage of the Service. You can control cookies through your browser settings; disabling them may affect parts of the Service.

6. Your Rights and Choices

You may access, correct, or update your account information at any time by signing in. You can request deletion of your account and associated data by contacting us at the email below; we will process such requests within a reasonable time, subject to legal record-keeping obligations.

7. Children's Privacy

The Service is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us so we can delete it.

8. International Users

By using the Service, you understand that your information may be processed in countries other than your own, which may have different data-protection laws than your jurisdiction.

9. Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will revise the "Last updated" date above. Significant changes will be communicated through the Service or by email.
