User Data Security Policy

Welcome to purchase products from our company (operating an electronics business in the United States). This policy defines the rules for user data processing, strictly following U.S. data security regulations to protect user data. If you have any questions, please contact our customer service at +86 19202338340. Our working hours are Monday to Friday, 9:00 AM to 6:00 PM (UTC+8:00).

1. Scope of the Policy

This policy applies to all user data (personal information, order data, etc.) collected and processed by our company when users browse our platform, place orders, or use customer service and related services. It does not apply to the data rules of third-party platforms (payment, logistics).

2. Data Collection and Use

We adhere to the principles of "lawful, fair, and necessary" data collection. We only collect the data required to provide services, specifically as follows:

• Order and Delivery Data: Name, phone number, address, email, used for order confirmation, order editing/changes within 12 hours, logistics arrangement, and status notifications (orders in stock are shipped within 1-2 business days, actual delivery time is 5-7 business days).

• Payment Data: Only basic information of payment accounts (e.g., last 4 digits of credit card) is indirectly collected to confirm payments and process refunds. Sensitive payment information is not stored.

• After-Sales and Usage Data: Order number, product model, consultation records, etc., used for responding to inquiries, providing after-sales support, and optimizing services.

• Data will only be used for the above purposes and will not be used for commercial promotion or data trading.

3. Data Security Protection Measures

We adopt multiple measures to prevent data leakage, tampering, or abuse, ensuring data security:

• Encryption Protection: All data collection, transmission, and storage processes are encrypted.

• Access Control: Strict restrictions on data access, with regular audits.

• Security Monitoring: 24/7 monitoring for abnormal operations and immediate risk management.

• Compliance Control: We follow U.S. data cross-border transfer regulations and will not illegally transfer sensitive data.

• Personnel Management: Relevant personnel undergo security training and sign confidentiality agreements.

• Technology Upgrades: Regular security system upgrades and vulnerability fixes.

4. Data Storage and Destruction

1. Data is stored on dedicated servers that meet U.S. standards and is retained only for the duration required for service.

2. Upon the termination of services, expiration of the storage period, or user request, data will be completely deleted or anonymized, with destruction records kept.

3. Sensitive data is managed with tiered controls, and transaction and processing records are retained for at least 10 years for auditing purposes.

5. Data Sharing and Disclosure

We will not casually share or sell user data. Data will only be disclosed in the following compliant scenarios:

• Sharing necessary data with logistics and payment institutions solely for completing delivery and payment.

• Disclosure to judicial or administrative authorities as required by law.

• Anonymized non-personal data may be shared with third parties for service optimization.

6. User Data Rights

Users have the legal right to access, correct, delete their data, and withdraw consent. Users can request this via customer service at +86 19202338340, and we will respond within 1-2 business days.

7. Policy Updates and Contact Information

This policy may be revised in accordance with legal regulations and business needs. Updates will be published on our official website, and users will be notified of changes affecting core rights.
