1. Scope and operator
This Privacy Policy applies to the Sinuo Network website and the related ad management, data reporting and Facebook login authorization services operated by Shenzhen Sinuo Network Technology Co., Ltd. (registered Chinese name: 深圳斯诺网络科技有限公司; “we”, “us” or “our”).
This website provides company and policy information. It does not directly offer Facebook login, user registration or information collection forms. Processing of Facebook data takes place only when you actually use the relevant application features and grant authorization. The specific data depends on the features used, your consent and permissions approved by Meta.
This policy does not replace Meta's own privacy policy. Your activity on Facebook is also subject to Meta's terms and policies.
2. Information we process

| Contacting us | Names, contact details, inquiry content and necessary business information you provide by email or phone. | Respond to inquiries, provide support, verify and handle rights requests. |

3. Use and disclosure
We process necessary information to provide the services you use, fulfill our agreement with you, respond to inquiries, maintain security and comply with applicable legal obligations. Platform data is used within granted permissions and platform rules, consistent with the purposes communicated to you.
We do not sell your personal information or Meta Platform Data. Relevant information may be provided to necessary service providers or legally authorized authorities to operate the website, host services, provide technical support or comply with law. Disclosures are limited to what is necessary and subject to applicable obligations.
If new features require new types of data, changed purposes or activities requiring separate consent, we will provide notice and obtain the necessary authorization before that processing occurs.
4. Retention and security
We retain information for the period necessary to fulfill the purposes described in this policy, considering service usage, authorization status, deletion requests and applicable legal obligations. When a purpose is fulfilled, authorization no longer applies or verified deletion is required, we delete or anonymize the relevant information. Legally required records are restricted to the necessary purposes and addressed when the retention obligation ends.
For service data, we apply reasonable access restrictions, transmission protections and credential management measures based on risk. Internet transmission and storage involve risks. If a security incident affects your rights, we will respond and provide notifications as applicable.
Where applicable law requires additional notice or consent concerning data location, cross-border transfers or outsourced processing, we will fulfill that requirement before the relevant processing takes place.
5. Your choices and deletion
You may contact us to request access to, correction of or deletion of information relating to you, or to exercise other applicable data rights. To prevent impersonation, we may request proportionate evidence of identity or control over the relevant resources.
You can revoke access by locating the relevant application in Facebook settings, such as “Apps and websites” or “Business integrations”. Labels may vary by account type and interface version. Revoking authorization and deleting data already stored in our services are separate actions.
To request deletion of information we hold, read our Data Deletion Instructions and email info@sirwintech.com. After verifying your request, we will communicate its scope, expected timeline and outcome, and explain any legal retention requirements or parts we cannot process.
6. Cookies, children and updates
This website does not actively set advertising, behavioral analytics or marketing cookies and does not embed the Facebook login SDK. Hosting services may use technologies necessary for operation and security. If relevant features are added, we will update these disclosures and provide choices where applicable.
Our business services are intended for businesses and their authorized users, not children. Contact us if you believe a child has provided personal information to us so we can investigate and address it.
We may update this policy as services or requirements change and will display the updated date on this page. Material changes in processing will be notified separately where required.
