Privacy Policy

Effective date: June 22, 2026

Changchun Haochuanyun Technology Co., Ltd., operating under the trade name Vast River, respects your privacy. This policy describes how we handle information when you interact with our website, communications, and services.

1. Information we collect

We collect only the information you provide directly — your name, email address, phone number, and the content of your messages when you contact us. Our website does not use tracking cookies, advertising pixels, or third-party analytics scripts. We do not collect browsing history, device fingerprints, or location data.

Our hosting infrastructure may log standard technical data — IP addresses, request timestamps, and user-agent strings — retained for a maximum of 30 days for security and diagnostic purposes only.

2. How we use information

Information you provide is used solely to respond to your inquiry, deliver the services you have requested, and maintain our business relationship. We do not use your information for marketing automation, profiling, or automated decision-making.

3. Information sharing

We do not sell, rent, trade, or share your personal information with third parties. The limited exceptions are:

  • Service providers who process data on our behalf under binding confidentiality terms — such as our email provider and cloud infrastructure host.
  • When required by applicable law, regulation, or legal process.

4. Data retention

We retain correspondence and business records for the duration of our engagement plus a reasonable period thereafter as needed for legal and operational purposes. Server logs are retained for 30 days. You may request deletion of your personal data at any time by contacting us at the address below.

5. Data security

We apply industry-standard technical and organizational measures to protect the information we hold. No method of electronic storage or transmission is perfectly secure, and we cannot guarantee absolute security. We review our security practices regularly and update them as threats evolve.

6. Your rights

Depending on your jurisdiction, you may have rights to access, correct, delete, or port your personal data, and to object to or restrict certain processing activities. To exercise any of these rights, contact us using the details below. We will respond within the timeframe required by applicable law.

7. International transfers

Vast River is based in the People's Republic of China. Information you provide may be processed in China and in other jurisdictions where our infrastructure operates. By using our services, you acknowledge that your information may be transferred across borders. We take appropriate safeguards to ensure your data remains protected regardless of where it is processed.

8. Children

Our services are not directed to individuals under the age of 16. We do not knowingly collect information from children. If you believe a child has provided us with personal data, please contact us so we can delete it.

9. Changes to this policy

We may update this policy from time to time. Material changes will be noted on this page with a revised effective date. Continued use of our services after changes constitutes acceptance of the updated policy.
