User Data Collection and Usage Statement

Last Updated: March 13, 2025

This statement aims to clearly explain the measures taken by China Telecom Quantum Cipher Manager Platform/System to collect, use, and protect users' personal information.

I. Scope of Information We Collect

Account Information

Email address provided during user registration (for identity verification and login)

Encrypted Data (stored securely using encryption algorithms through this platform/system)

Website information saved by users

Application account passwords

Document notes

Other User Information

User phone number (for two-factor verification)

User organization information (for user-defined permission control)

II. Purpose and Usage of Data Collection

Core Function Implementation

Providing users with secure password storage, auto-fill, and cross-device synchronization services

Security Protection

Detecting abnormal login behaviors to prevent unauthorized access

Service Optimization

Analyzing product performance issues through anonymized statistical data (without involving specific user content)

III. Data Storage and Protection

Encryption Standards

PQC anti-quantum attack encryption algorithms (for advanced users)

SM2/SM3/SM4 encryption algorithms (for regular users)

Using true random numbers generated by quantum cryptographic devices for session keys (full encryption of data)

Zero-Knowledge Architecture

Encryption keys are managed and controlled by dedicated quantum cryptographic devices; servers cannot decrypt stored content

Physical Protection

Data stored in ISO 27001-certified secure data centers

Regular third-party security audits and penetration tests

Transmission Security

SPA (Single Packet Authorization) scheme to enhance system boundary protection and further secure data transmission

HTTPS transport layer encryption (TLS 1.2+)

IV. Data Usage Restrictions

❌ Never sell, rent, or share user password data with third parties

❌ Never use user data for advertising or commercial analysis

❌ Never require users to provide real names, addresses, or other unnecessary information ( The "ephemeral message" feature requires real-name authentication. )

V. User Rights Protection

Data Control Rights

Users can export/delete all data at any time

Supports enabling/disabling two-step verification

Right to Know

Notify users via registered email 30 days before major policy changes

Appeal Channels

Security concerns feedback: qcm.gz@chinatelecom.cn

VI. Policy Updates

This statement will be revised according to technological developments and legal requirements. Updated versions will be prominently displayed on the official website.
