The following details our security measures and frequently asked account questions to help you use our services with peace of mind.

Our security measures

SSL encrypted transmission

The entire site is encrypted with HTTPS, and a 256-bit SSL certificate protects all data transmission, preventing eavesdropping and man-in-the-middle attacks.

Information protection

Payment passwords and bank card information are not stored; payments are processed by a third-party security platform, and only necessary order records are retained.

Privacy protection

We strictly adhere to our privacy policy; personal information is used solely for service delivery and will never be sold to third parties or used for marketing.

Regular cleaning

Regularly clean up expired orders and cached data to reduce server storage and lower the risk of data leaks.

Account FAQs

We retain only the minimum amount of information necessary to complete the service, adhering to the principle of data minimization and never excessively collecting user data.

  • Order-related information (order number, service type, status) – used for order processing, status tracking, and after-sales inquiries.
  • Contact information (for order notifications) – used only when order status changes or confirmation is required, and will not be used for any marketing or promotional purposes.
  • Sensitive data such as payment passwords and bank card information are not stored—all payment operations are completed through a secure third-party payment platform.
  • Completed order information will be automatically cleared after a reasonable period of time and will not be retained permanently.

If you have any concerns about data storage, please feel free to contact customer service for more details. We will patiently answer all your questions about data storage.

Absolutely not. Protecting user privacy is one of our core commitments, and we strictly control every aspect of data management:

  • We will not sell user data to any third party—your personal information is not a commodity, and we will never sell it to advertisers, data brokers, or any other organization.
  • We will not share your personal information for marketing purposes—you will not receive promotional messages from third parties because of your use of our services.
  • Cooperate with relevant departments only when required by law—provide necessary information only to the extent permitted by law upon receipt of formal legal documents or judicial orders.
  • Internal access is strictly limited—only the personnel responsible for processing your order can access the necessary order information.

You can view our privacy policy page for full privacy terms and data usage guidelines.

While we provide comprehensive security protection at the technical level, your personal security awareness is equally important. Please follow these recommendations to further protect the security of your orders and personal information:

  • Keep your order number safe and do not share it with strangers—the order number is the only credential for querying and managing your order; disclosing it may result in your order information being obtained by others.
  • Use a secure network environment for your operations—avoid placing orders and making payments on public Wi-Fi or insecure network environments. We recommend using personal mobile data or a home network.
  • Clear your browser cache after completing the transaction—especially when using a shared computer or public device, clearing browsing history and cache can prevent others from seeing your transaction information.
  • Contact customer service immediately if you encounter any suspicious activity—If you discover any unusual order changes, receive suspicious notifications, or encounter someone impersonating customer service, please contact us through official channels immediately.
  • Regularly check your order records – monitor order status changes promptly to confirm that all orders were initiated by you.

Developing good cybersecurity habits and working with our technical safeguards can maximize the protection of your account and order security.

We respect your right to control your personal data. If you wish to delete your personal data on our platform, please follow these steps:

  • Please contact customer service to submit a data deletion request – send the data deletion request via Telegram or other official customer service channels.
  • Provide verification information to confirm your identity – To prevent unauthorized deletion of your data, we need to verify your identity, which usually requires providing your order number or the contact information used when placing the order.
  • We will process your request within 7 business days – once we receive a verified deletion request, our technical team will complete the data deletion operation within 7 business days.
  • We will notify you after the deletion is complete—we will contact you via the contact information you provided to confirm the data deletion is finished.

Please note that some records that must be retained due to legal compliance requirements may not be deleted, but these records will not be used for any other purpose. If you have any questions, customer service will provide you with detailed information.
