We value your privacy and will not sell, trade, or otherwise transfer your personal information to unrelated third parties. We may share information in the following circumstances:

3.1 With Service Providers

  • We may share limited information with trusted service providers to support service operations. For example:
    • Analytics Services: We share anonymized device identifiers and behavior data with Google Analytics to analyze service usage and improve functionality. See Google Privacy Policy for details.

3.3 Anonymized Data

  • We may share anonymized or aggregated data (e.g., service usage statistics) that does not contain any personally identifiable information.

4. Data Storage and Cross-Border Transfer

  • Storage Location: Text data submitted by users is stored on Tencent Cloud servers located in Hong Kong. User-uploaded files are stored on Cloudflare or RainCloud object storage services, depending on the selected storage pool.
