Privacy Policy
How this website handles inquiries and optional usage counts.
Who to contact
This website presents 3GRACE products from Zhejiang Shengyu Electrical Co., Ltd. For questions about a website inquiry, contact gaotuo38@gmail.com or shengyu-gt@gfci.cn. Include the inquiry reference if you have one.
Information in an inquiry
The inquiry form asks for your name, email address and requirement. Product, company, country or region, quantity and phone details are optional. We use the information you choose to send to understand and respond to your product or document request.
How sending works
Preparing, copying or downloading a draft does not submit it to our team. Email links open your own email application. When website sending is enabled, the server forwards your reviewed inquiry through Resend to gaotuo38@gmail.com and shengyu-gt@gfci.cn. A provider acceptance message is separate from delivery confirmation.
Website records and retention
The website database stores an inquiry reference, a one-way content fingerprint, model, language, provider message reference and delivery status. It does not store your name, email address, phone number or inquiry text. This non-content receipt trail is retained without a scheduled deletion date to preserve a permanent delivery audit. Email copies held by Resend and the two recipient mailboxes are separate records and contain the inquiry fields you submitted.
Optional analytics and abuse prevention
Optional analytics runs only when enabled and allowed in your browser. It counts page views and contact actions by day, page, language and broad referral category, without visitor identifiers or form text. Counts older than 90 days are removed on subsequent analytics activity. Short-lived, keyed IP fingerprints limit automated requests; raw IP addresses are not saved in the website database. Hosting and email providers may process operational data under their own service policies.
Your choices
You can leave optional inquiry fields empty, use your own email application, or decline optional analytics. Use the Cookie Policy page to change your saved analytics choice. Contact the addresses above to ask about an inquiry you have sent or to request correction or deletion of information held in the recipient mailboxes. Do not include payment details, passwords or confidential credentials in the form.
