ChineseBloom Privacy PolicyChineseBloom 隐私政策

1. Who we are

ChineseBloom is operated by Hanyin Jinyu Education Technology (Nanjing) Co., Ltd. (“Hanyin Jinyu”, “we”, “us” or “our”). This policy explains how we handle personal information when you use ChineseBloom, our website and related support services.

2. Information we may process

• Account information: email address, sign-in identifier, display name and encrypted authentication information.
• Learning information: study progress, saved vocabulary, practice history, settings and language preferences.
• Purchase information: product identifier, transaction status, subscription entitlement and platform receipt information. We do not receive your full payment-card number from Apple or Google.
• Speaking practice: microphone audio and reference text needed to provide pronunciation assessment.
• Support information: messages, diagnostic details and contact information you voluntarily provide.
• Technical information: app version, device and operating-system information, network and error information needed for security and reliability.

3. How we use information

We use information to provide accounts and learning features, synchronize progress, process and restore purchases, provide pronunciation results, respond to support requests, maintain security, diagnose failures and meet legal obligations. We do not sell personal information.

4. Microphone and speech assessment

ChineseBloom asks for microphone access only when you choose a recording or speaking feature. Audio and the corresponding reference text are transmitted securely to Tencent Cloud solely to generate a pronunciation-assessment result. Under the production design, the raw recording is not stored after assessment is completed. Assessment results may be associated with your learning record where needed to show progress.

5. Service providers

We use Tencent Cloud for cloud infrastructure and pronunciation assessment. We may also use providers for transactional email, diagnostics and customer support. Apple and Google process app-store purchases under their own terms and privacy policies. We require service providers that process personal information on our behalf to protect it appropriately and use it only for the contracted purpose.

6. International processing

Because ChineseBloom is intended for users in multiple countries, information may be processed in a country different from where you live. We will use appropriate contractual and technical safeguards where required.

7. Retention

We retain account and learning information while your account is active and for the period reasonably needed to provide the service. Purchase and transaction records may be retained where required for accounting, fraud prevention and legal compliance. Support records are kept only as long as reasonably necessary. Final retention periods will be confirmed before release.

8. Your choices and rights

Depending on your location, you may have rights to access, correct, export or delete personal information, object to or restrict certain processing, and withdraw consent. You can change device permissions in system settings and request account deletion through our account deletion page.

9. Children

ChineseBloom is not currently designed as a service directed specifically to children. If the released service is offered to children or used in a school-directed context, we will introduce the additional notices, consent mechanisms and protections required by applicable law before doing so.

10. Security

We use reasonable administrative, technical and organizational measures designed to protect personal information. No method of transmission or storage is completely secure, and we cannot guarantee absolute security.

11. Changes

We may update this policy as our services or legal obligations change. We will post the revised version and update its effective date, and provide additional notice where required.
