This policy applies to all users who purchase tools, 3C products, and use services through Lomtrixj in the United States. It outlines how we collect, use, store, and protect your personal data and transaction information, as well as the data rights you are entitled to. We strictly follow relevant U.S. data security and privacy protection regulations, aiming to provide a secure, transparent, and controllable data environment.

To process orders, provide delivery services, offer customer support, and optimize services, we only collect necessary information, including but not limited to:

• Order and Transaction Information: Name, shipping address, phone number, email address, payment method information (without storing sensitive payment passwords or verification codes), order number, product details, payment records, and shipping and logistics information.

2. Purpose of Using Your Information

We use your information only for the following legal and necessary purposes and do not use it for unauthorized activities:

• Order Processing and Fulfillment: Confirm orders, complete payments, arrange shipments (stocked orders typically ship within 1-2 business days, excluding weekends and holidays), logistics delivery (actual delivery in 5-7 business days), and process order editing/change requests within 12 hours.

• Customer Service and After-Sales: Respond to your inquiries, complaints, warranty claims, return/exchange requests, provide order status tracking, logistics tracking, and troubleshooting services.

• Security and Compliance Checks: Prevent fraud, unauthorized transactions, and unusual activities, ensuring account and transaction security, and complying with U.S. laws, regulations, and supervision requirements.

• Service Optimization: Analyze user needs and service experiences in an anonymized and de-identified manner to improve products and processes, without engaging in unauthorized targeted marketing based on personal data.

3. Data Storage and Protection Measures

Lomtrixj places a high priority on data security and employs multiple technical and management measures to comprehensively protect your personal data and transaction information:

• Encryption Protection: We use internationally recognized encryption technologies to encrypt your personal information, payment-related information, and order data during transmission and storage to prevent unauthorized access, tampering, or leakage.

• Access Control: Access to data is strictly limited to authorized personnel who need it for fulfillment, customer service, or security verification. All data access is traceable.

• Secure Storage: All data is stored on secure servers that comply with U.S. data security standards, equipped with firewalls, intrusion detection, antivirus, and other security protection systems. Regular security checks and vulnerability fixes are performed.

• Data Retention: We only retain data for the necessary period to fulfill the purposes described in this policy. After completing the order, service termination, or exceeding the statutory retention period, your personal data will be anonymized or securely deleted, and no identifiable personal information will be retained.

4. Information Sharing and Disclosure Rules

We commit not to sell, rent, or disclose your personal data to any unrelated third party. We will only share your information in the following legal or necessary circumstances, and require the recipient to adhere to equivalent data security standards:

• Necessary Sharing for Fulfillment: Share necessary order, shipping, and payment information with logistics providers (for order delivery) and payment institutions (for transaction completion), solely for the purpose of fulfillment and not for other purposes.

• Legal Compliance Disclosure: Disclose necessary information in accordance with U.S. laws, regulations, or judicial/administrative authorities' legal requirements.
