Who is responsible
Shenzhen Huashengxin Circuit Co., Ltd., 101, Workshop 8, No. 24 Taixing Industrial City, Hongxing Community, Songgang Street, Bao’an District, Shenzhen, China. Email: sales@hsxpcb.com.
What we collect
When you send a quote request or message: your name, email address, company, country, phone number, your board requirements and any files you upload.
When you allow analytics: pseudonymous usage data collected by Google Analytics 4, such as pages viewed, approximate location and device type. Analytics is only loaded after you agree.
Why we use it
To answer your request, prepare quotes and fulfil orders (pre-contractual and contractual necessity).
To understand which pages are useful and improve the website (your consent, which you can withdraw at any time).
Where it is processed
Request data is delivered to our sales mailbox and our internal WeCom (Enterprise WeChat) workspace in China. Uploaded files are stored with our hosting provider, Cloudflare. Google Analytics data is processed by Google. Some of these providers process data outside your country, including in the United States and China.
How long we keep it
Quote requests and files are kept for up to three years so we can handle repeat orders, unless you ask us to delete them sooner. Order records are kept as long as tax and accounting law requires.
Your rights
You can ask for access to, correction of or deletion of your data, object to its use, or withdraw analytics consent by clearing this site’s storage in your browser. Write to sales@hsxpcb.com. If you are in the EU, you may also complain to your data protection authority.
Cookies and storage
We store your analytics choice in your browser’s local storage. If you allow analytics, Google Analytics sets its own cookies (_ga, _ga_*). We do not use advertising cookies.
