WEBSITE POLICIES · UPDATED OCTOBER 15, 2026
Privacy Policy
This policy explains what information we receive, why we use it, and how to contact us about your privacy.
Who is responsible
Foshan Yingjia Building Material Co., Ltd. operates the ENGGIA website and handles the inquiries sent to us. This policy covers website visits and communications about our windows, doors and customization services. For questions about your information, email sales@yingjiawindowsdoors.com.
Information you provide
Our inquiry forms ask for your name, email address and message. The quote form also asks for your product interest and lets you add an estimated quantity and supporting files. We receive any further information you choose to include in a message, drawing or attachment, such as dimensions, delivery requirements or additional contact details. Please share only what is relevant to your inquiry and ensure you have permission to provide information about other people.
Information about website visits
Website requests and inquiries may include your IP address, browser information, page address, referring page, language and time of submission. We may also receive campaign parameters, advertising click identifiers, and available Google Analytics client and session identifiers. These help us understand where an inquiry came from and protect the forms from abuse. Recording a click on an email or WhatsApp link does not give us access to the conversation in that service.
How we use information
We use inquiry information to answer questions, discuss specifications, prepare quotations and communicate about requested products or orders. We use technical information to run and secure the website, investigate errors and prevent spam. Analytics and campaign information help us understand how visitors find the website and which pages and campaigns lead to inquiries.
Who may receive information
Cloudflare supports website hosting, request processing and security. Google provides analytics and campaign measurement. Personnel and service providers who help us manage correspondence, quotations and orders may access information needed for that work. Relevant project details may be shared where necessary to respond to or fulfil your request. We may also disclose information when required by applicable law or to protect legal rights.
Embedded YouTube video
The homepage includes a YouTube player in privacy-enhanced mode. Loading or playing the video connects your browser to YouTube, which processes information under Google's privacy policy. You can also follow the link to watch on YouTube. Google's privacy information is linked below.
Turnstile verification
Our forms use Cloudflare Turnstile to help distinguish people from automated traffic. Cloudflare processes signals such as IP addresses and browser and connection information to provide and improve this protection. Its Turnstile Privacy Addendum explains its role and processing in more detail; see the link below.
Where information is processed and kept
Our business is based in China. Information may be processed in China and in countries where our service providers operate. We retain inquiry and business records for the purposes described here, including handling your request, maintaining the business relationship, meeting applicable recordkeeping obligations and resolving disputes. Retention depends on the type of record and its purpose. Contact us about a particular record or deletion request.
Cookies and Google Analytics
We use Google Analytics on the public website to understand visits and inquiry interactions. Its first-party cookies, including _ga and _ga_<container-id>, distinguish visitors and sessions. Campaign information may be used to measure advertising results. The website's custom analytics events do not include the name, email address, message or files entered in the form. Cookie lifetimes depend on the service settings and your browser. Google's cookie and privacy information is linked below.
Remembering an inquiry's source
The website keeps a campaign-source record in your browser's local storage, named b2b-attribution-v1. It contains campaign identifiers, a referring page without its query string, and a timestamp. This helps associate a later inquiry or contact click with its source. The site stops reusing a record after 30 days, and later visits may replace it. The record does not contain your form message or attachments. Clear the website's browser data to remove it.
Selected products and form drafts
A temporary session-storage record named inquiry-context carries a product or document selection to the quote form. It is removed after the selection is inserted into the form; otherwise it follows your browser's tab-session lifetime. The website does not store completed form drafts in browser storage. Your browser may independently offer autofill or restore a page. After a successful submission, the form resets.
Browser controls and security features
Cloudflare services may use security-related cookies or storage according to their settings. You can inspect, restrict or clear cookies and site data through your browser. Blocking scripts or storage may affect form verification and saved selections. Clearing browser data does not delete information you have already sent to us. If the form does not work with your settings, contact sales@yingjiawindowsdoors.com.
Your choices and requests
Email sales@yingjiawindowsdoors.com to ask about information we hold, request a correction or deletion, or ask us to stop optional communications. Depending on the law that applies to you, you may have additional rights to object, restrict processing, receive a copy of information, withdraw consent or contact a relevant supervisory authority. We may request information needed to verify your identity and explain any applicable limits on a request.
Security and external services
Website and form connections use HTTPS. Please avoid sending passwords, payment-card details or unrelated sensitive documents through an inquiry. No online transmission or storage system is completely secure. When you follow a link to WhatsApp or another external service, that service's own privacy terms apply.
Changes and contact
We may revise this policy as the website or our practices change. The date above shows the current version. Send privacy questions to sales@yingjiawindowsdoors.com and identify the inquiry or record concerned so we can help you.
