Privacy Policy
1. Who We Are
Chinese Planet ("we", "us", "our") operates the website accessible at the domain where this policy is published (the "Service"), a platform for learning Chinese and preparing for the HSK exams.
This Privacy Policy explains what information we collect, why we collect it, and the choices you have. It applies to all visitors and users of the Service, including those who use it without creating an account (guest users).
2. Information We Collect
Account information: if you register, we store your username, email address and a password hash. Email is used only for account recovery and service notices.
Learning progress: to let you pick up where you left off, we store your study records (words learned, review scores, mastery status and scheduled review dates) tied to your account or, for guests, to a pseudonymous identifier stored in your browser.
Usage data: we keep basic technical logs (IP address, browser type, pages visited, timestamps) to operate, secure and improve the Service.
Cookies and similar technologies: see our Cookie Policy for details. We use strictly necessary cookies (e.g. session and guest identifier) and, if enabled, analytics cookies.
3. Why We Process Your Data (Legal Bases)
Performance of a contract: providing the learning and exam features you use, and delivering account functionality.
Legitimate interests: improving the Service, ensuring security, and preventing abuse. We balance these interests against your rights.
Consent: where required by law (e.g. certain analytics cookies), we ask for your consent and you may withdraw it at any time.
4. Cookies and Local Storage
We use a cookie (hsk_guest) to save your learning progress when you learn without an account, and session cookies when you log in.
Analytics cookies, if enabled, help us understand aggregate usage. Third-party services may set their own cookies; please review their policies.
You can delete or block cookies in your browser settings. Blocking necessary cookies may limit core features such as saved progress.
5. How We Share Information
We do not sell your personal information. We share data only with service providers that help us operate the Service (e.g. hosting), under data-processing agreements, and where required by law or to protect rights and safety.
6. Data Retention
Account data is retained while your account is active. Guest progress is retained for up to 12 months after last activity. Logs are retained for up to 12 months. You may ask us to delete your data at any time.
7. Your Rights (GDPR)
Depending on your location, you may have the right to access, correct, delete, restrict or export your personal data, to object to processing, and to withdraw consent.
To exercise any of these rights, contact us (see Section 11). We respond within one month. You may also lodge a complaint with your local data protection authority.
8. Children
The Service is intended for users aged 16 and above (13 in some jurisdictions, subject to local law). We do not knowingly collect personal data from children. If you believe a child has provided data, contact us and we will delete it.
9. International Transfers
Your data may be processed on servers located in different countries. Where we transfer personal data across borders, we rely on appropriate safeguards recognised under applicable law (e.g. adequacy decisions or standard contractual clauses).
10. Security
We apply reasonable technical and organisational measures, including encryption in transit and hashed passwords, to protect your information. No method of transmission is 100% secure, so we cannot guarantee absolute security.
11. Contact
Questions about this policy or data requests: contact us through the contact information provided on the Service. We aim to respond within one month.
