Privacy Policy

1. Introduction

Changzhou Weixing Computer Room Co., Ltd. (“Weixing,” “we,” “us,” or “our”) respects your privacy. This Privacy Policy explains how we collect, use, store, disclose, and protect information in connection with our website and our internal advertising management tools, including integrations with the Amazon Ads API.

2. Information We Collect

Depending on how you interact with us, we may collect:

• Contact information: information you voluntarily provide when contacting us, such as your name, email address, telephone number, company, and message.
• Basic website data: standard server logs such as IP address, browser type, requested page, access time, and error data, used to maintain security and reliability.
• Amazon Ads account data: when an authorized user connects an advertising account, we may access advertising profile identifiers, marketplace and account information, campaigns, ad groups, advertisements, keywords, targeting settings, budgets, bids, campaign status, and advertising performance reports and metrics made available through the Amazon Ads API.
• Authorization data: access and refresh tokens or related technical identifiers required to maintain an authorized Amazon Ads API connection. We do not collect or store users’ Amazon passwords.

3. How We Use Information

We use information only for legitimate business purposes, including to:

• respond to inquiries and provide requested support;
• operate, secure, troubleshoot, and improve our website and tools;
• retrieve, organize, analyze, and report advertising performance for advertising accounts that have expressly authorized access;
• manage campaigns, budgets, bids, keywords, targeting, and related advertising operations on behalf of authorized account owners;
• detect errors, misuse, unauthorized access, or security incidents; and
• comply with applicable laws, contractual duties, and platform policies.

We access only the Amazon Ads data reasonably necessary to provide the authorized advertising management functionality. We do not use Amazon Ads data for unrelated advertising, individual profiling, or unauthorized surveillance.

4. Authorization and Control

Amazon Ads API data is accessed only after the relevant account owner or authorized representative grants permission through Amazon’s authorization process. Authorization may be revoked through the applicable Amazon account settings or by contacting us. After revocation, we will stop new access and delete associated data when it is no longer needed, subject to legal retention requirements.

5. Sharing and Disclosure

We do not sell, rent, license, or publicly disclose personal information or Amazon Ads data. We may disclose limited information:

• to service providers that support hosting, infrastructure, maintenance, or security, only where necessary and subject to confidentiality and data-protection obligations;
• when required by law, legal process, or a valid request from a competent authority; or
• to protect the rights, safety, security, and integrity of our company, users, systems, or the public.

Amazon Ads data is not combined with unrelated third-party data or provided to unauthorized third parties.

6. Data Retention and Deletion

We retain information only for as long as necessary for the purposes described in this policy, to provide the authorized service, or to meet legal and contractual requirements. Amazon Ads data is deleted when it is no longer required for the authorized integration, when access is terminated, or upon a valid deletion request, unless retention is required by law. Backup copies are removed through our normal backup lifecycle.

7. Data Security

We use reasonable administrative, technical, and physical safeguards designed to protect information against unauthorized access, loss, misuse, alteration, or disclosure. These measures include access controls, least-privilege permissions, secure transmission, credential protection, system monitoring, and restricted access to personnel with a business need to know. No system can guarantee absolute security.

8. Cookies and Tracking

This public website does not use advertising cookies or third-party analytics. Essential technical logs may be generated by our web server for security, diagnostics, and reliable operation.

9. Your Choices and Rights

Subject to applicable law, you may request access to, correction of, or deletion of your personal information, object to or restrict certain processing, or withdraw consent where processing relies on consent. You may also report a privacy concern, security vulnerability, suspected misuse of Amazon Ads data, or security incident using the contact details below. We will review and respond to valid requests within a reasonable period.

10. International Processing

Information may be processed in countries or regions where we or our service providers operate. Where required, we use appropriate safeguards for cross-border transfers and process information in accordance with applicable data-protection law.

11. Children’s Privacy

Our website and business tools are intended for businesses and authorized adult users. They are not directed to children, and we do not knowingly collect personal information from children.

12. Changes to This Policy

We may update this Privacy Policy to reflect changes in our practices, services, legal obligations, or platform requirements. The current version will be published on this page with a revised effective date.
