1. Introduction

This Privacy Policy explains how qingwx entities (for the purposes of applicable European data protection laws, the qingwx entities providing advertising services subject to GDPR, collectively referred to as “qingwx”, “we”, “us”, or “our”) collect, use, and process information through our advertising platform (“Advertising Service”) and our website. This Privacy Policy applies unless otherwise specified in a separate service agreement between you and qingwx. By accessing or using our Advertising Service or website, you acknowledge that you have reviewed and understood this Privacy Policy. We encourage you to read this policy carefully before using our services.

2. Policy Updates

We periodically review and update our privacy practices to reflect changes in legal requirements, technology, and business operations. This Privacy Policy may be updated from time to time, and at minimum will be reviewed annually. If we make material changes, we will provide a clear notice on our website prior to such changes becoming effective.

3. Information We Collect

When you view or interact with advertisements delivered through qingwx’s Advertising Service, or when you engage with services provided by our business partners, we and/or our partners may collect certain information. This may include device and technical data (such as device type, operating system, IP address, advertising identifiers, browser information), approximate location data, interaction and usage data, and transactional information related to your activities within applications, websites, or digital services. We may also collect system and log data, including crash reports, system activity, and request-related metadata. In addition, when advertisers, publishers, or partners use our platform, we may collect account-related information such as contact details, login credentials, IP addresses, and business-related information.

4. How We Use Information

We use collected information to deliver and manage advertising on devices, including serving ads based on inferred interests, preferences, and approximate location where permitted by law. Users may choose to opt out of interest-based advertising; however, opting out does not eliminate advertising and non-personalized ads may still be displayed. We also process information to analyze usage trends, improve and optimize our Advertising Service, ensure traffic quality, and prevent fraud, which supports our contractual obligations to advertisers and publishers. In certain cases, we may process personal information to comply with applicable legal obligations, regulatory requirements, or industry standards.

5. Information Sharing

We may share personal information with trusted business partners, including advertisers, publishers, analytics providers, and measurement partners, for purposes such as ad delivery, performance measurement, attribution, and traffic analysis. These partners process information in accordance with their own privacy policies. We may also share information with affiliated companies, as well as third-party service providers who perform services on our behalf under appropriate confidentiality and data protection obligations. Aggregated or anonymized data may be shared with third parties in accordance with this Privacy Policy. Additionally, we may disclose information where required by law or in connection with legal proceedings, regulatory requests, or corporate transactions such as mergers, acquisitions, or asset transfers.

6. International Data Transfers

If you are located in the European Economic Area (EEA), information collected from you may be transferred to, stored, and processed in countries outside the EEA. These jurisdictions may not provide the same level of data protection as the EEA and may include regions such as China, the United States, Singapore, Japan, and other locations where qingwx or its partners operate. Where required by law, appropriate safeguards will be applied, and consent will be obtained by publishers or advertisers when necessary. You may withdraw such consent at any time. qingwx implements standard contractual safeguards, including EU Standard Contractual Clauses, to protect international data transfers within our organization. Copies of these safeguards may be requested by contacting us.

7. Your Rights

Depending on your location, you may have certain rights regarding your personal information. For individuals in the EEA, these rights may include access, correction, deletion, restriction, objection to processing, and data portability, as well as the right to lodge a complaint with a supervisory authority. If you are a California resident, you may have rights under the California Consumer Privacy Act (CCPA), including the right to request information about data collected, used, or shared, to request deletion of personal data, and to opt out of the sale of personal information. Requests to exercise these rights may be submitted by contacting us. We may take reasonable steps to verify your identity before processing such requests, subject to applicable legal limitations.

8. Data Security and Retention

We implement reasonable technical, administrative, and organizational measures to protect personal information against unauthorized access, misuse, loss, or disclosure. These measures include access controls, encryption, network security, and secure data storage practices consistent with industry standards. Personal information is retained only for as long as necessary to provide our services, comply with legal obligations, resolve disputes, and enforce agreements. Retention periods depend on the nature and purpose of the data and applicable legal requirements.

9. Children’s Privacy

qingwx does not knowingly collect personal information from children under the age of 13 and complies with applicable children’s privacy protection laws. Our services are not directed toward children. If we become aware that personal information has been collected from a child without appropriate consent, we will take reasonable steps to delete such information promptly.

10. Marketing Communications

Where permitted by law, we may send marketing or promotional communications regarding our services. You may opt out of receiving such communications at any time by following the unsubscribe instructions provided in the message or by contacting us directly.
