Privacy policy
A plain-language description of what personal data this site collects, why we keep it, who handles it and what you can do about it. We only process what a business inquiry requires.
Who we are
This site is operated by Hangzhou chemlinkai Chemical Technology Co., Ltd. (the official English legal name is subject to confirmation by the company), based in Lin’an District, Hangzhou, Zhejiang, China. We are the data controller for personal data collected through this website.
What we collect
We collect only what is needed to answer you and, if the conversation continues, to serve you as a customer:
- Form data — the details you type into our inquiry or sample forms, such as your name, company, business email, country or region, industry, substrate, process, problem description and estimated volumes.
- Communication data — the content of emails, calls or messages you send us directly.
- Usage data — basic technical and analytics data collected through cookies as described in the cookie policy. Analytics processing only happens after you give consent.
How we use your data
We use the data you submit for the purpose you submitted it, and for closely related follow-up:
- To review and answer technical inquiries and sample requests.
- To prepare quotations, samples, trials and — if a contract follows — to perform that contract.
- To keep a written record of what was discussed and agreed, so both sides can rely on it.
- To comply with legal and record-keeping obligations where they apply.
- We do not sell personal data and we do not use it for automated decision-making that affects you.
Legal basis and retention
Our legal bases are your consent (where you give it, for example for analytics cookies) and our legitimate interest in responding to and managing business inquiries and relationships.
We retain data only as long as needed for the purpose it was collected, plus any period required by applicable law. If you ask us to delete your data and no legal obligation requires us to keep it, we delete it.
Third parties and international transfer
Forms are handled through our website hosting and form services, email and phone messages travel through the providers you would expect, and analytics data is processed by the analytics provider only when you have consented.
As a China-based supplier serving international customers, data you send may be processed in China and in the countries where our service providers operate, which may differ from your country. We choose providers on the basis of confidentiality and data-protection commitments appropriate to the data.
Your rights
You may ask us, at any time and free of charge:
- For access to the personal data we hold about you.
- To correct inaccurate data, or to delete data we no longer need for the purposes above.
- To object to or restrict certain processing, or to withdraw consent where processing is based on consent.
- To receive a copy of the data in a structured format where technically feasible.
- You also have the right to lodge a complaint with your local data-protection supervisory authority.
Changes and contact
We update this policy when the site’s processing changes. Material changes will be noted on this page with a new effective date.
Privacy questions and requests can be sent by email to ziqiang.yu@hywelt.com or to our registered business address in Lin’an District, Hangzhou, Zhejiang, China.
