This information helps us diagnose crashes, optimize app performance, and prevent fraud.
• Usage Log Information: When you use this App, the system may automatically record your access time, browsing history, click behavior, search keywords, content viewed, and in-app interaction data (such as feature usage frequency).
• Location Information: If required by App functions (e.g., maps, weather, or location-based services), we will collect your precise or approximate geographic location after obtaining your explicit consent. You can disable location permissions at any time in your device settings.
• Information from Third Parties: When you log in using a third-party account (e.g., Apple ID, Google, WeChat), we may receive your public profile information (such as nickname and profile picture) based on your authorization scope.

Special Note on Sensitive Information: We do not actively collect sensitive personal data such as your race, religious beliefs, health information, or biometric data, unless necessary for specific, legally permitted services and with your explicit consent.

3. Information Sharing and Disclosure

We promise not to sell your personal information. However, we may share your information with third parties in the following circumstances:

• Service Providers: We may share necessary information with trusted partners who provide technical infrastructure, data analysis, customer support, payment processing, or marketing services for the App. These partners may access your information only to perform their tasks on our behalf and are subject to strict confidentiality obligations.

4. Your Rights and Choices

We respect your control over your personal information. Depending on applicable laws and regulations, you may have the following rights:

• Right to Access: You can log into your App account at any time to view the personal information we hold about you.
• Right to Rectification: If your information is inaccurate or incomplete, you can edit it directly within the App or contact us for assistance in updating it.
• Right to Erasure: Under certain conditions (e.g., you withdraw consent, the data is no longer necessary), you may request the deletion of your personal information. You can also initiate the data deletion process by deleting your account.
• Right to Withdraw Consent: For data processing based on consent (e.g., location information, advertising tracking), you can withdraw consent through device settings or the App's permission management options.
• Right to Opt-Out of "Sale"/Sharing: We do not sell your personal information. If our policy changes in the future, we will provide opt-out options as required by law.
• Account Deletion: You can delete your account through the in-app "Settings - Account Deletion" feature (or by contacting customer service). We will process your request after verifying your identity and delete your information within a reasonable time, unless retention is required by law.

To exercise any of the above rights or if you have any questions about your information, please contact us using the information in Section 8. We will respond to your request within 30 days.

5. Data Storage and Security

Storage Location: Your information may be stored on servers operated by us or our service providers, which may be located outside your country/region. We will take necessary contractual and technical measures to ensure that your information receives the same level of protection as in your home country when transferred across borders.

Data Retention: We retain your information only for as long as necessary to fulfill the purposes described in this policy, unless a longer retention period is required or permitted by law. For example, account information is typically retained for 30 days after deletion for anti-fraud verification, after which it is anonymized or deleted.

Security Measures: We use industry-standard security technologies (such as SSL/TLS encryption for data transmission, data masking, access controls, and regular security audits) to protect your information from unauthorized access, disclosure, or breach. However, please note that no internet environment is completely secure, and you should also take care to protect your account password.

This App is not intended for children under the age of 13 (or a lower age as specified in your jurisdiction). If we discover that we have inadvertently collected personal information from a child under 13, we will take immediate steps to delete that information. If you are a parent or guardian and believe your child has provided us with personal information, please contact us immediately.
