Quote requests
When you send the quote form, we receive your name, company, email address, phone or WhatsApp number (optional), country, the grades, sizes and requirements you describe, any files you attach, and the page you sent the form from. Our server also records the time, your IP address and browser information.
We use this to answer your request and prepare a quotation, and the IP address and time to keep out spam and abuse. Fields marked * are needed to answer you; without them we cannot process the request.
Legal basis: Art. 6(1)(b) GDPR (steps taken at your request before a contract); for spam protection, Art. 6(1)(f) GDPR (our legitimate interest in a secure website).
Datasheet downloads
Before you download a PDF datasheet, we ask for your email address. We record it together with the datasheets you download, the time, your IP address and browser information. If you are in Europe, Japan, South Korea or an Arab country, we send you datasheet updates and quotations only if you tick the box for them; elsewhere, we send them unless you object. You can unsubscribe at any time by replying to one of our emails or writing to info@kochlin.com.
Legal basis: for the download record, Art. 6(1)(f) GDPR (our legitimate interest in providing technical information); for update and quotation emails, your consent under Art. 6(1)(a) GDPR, which you can withdraw at any time.
Email, phone and messaging apps
If you contact us directly, we use what you send us to reply. Messaging apps (WhatsApp, a Meta service; WeChat, a Tencent service; Telegram and VK) are run by other companies; messages you send through them are also handled under their own privacy policies.
Legal basis: Art. 6(1)(b) and (f) GDPR.
Visiting the website
Each visit is recorded in our server logs: IP address, time, the page requested and browser information. We use the logs to run the website and protect it against attacks, and keep them only as long as needed for that.
Legal basis: Art. 6(1)(f) GDPR.
We do not use analytics or advertising cookies, and our pages load no content from other companies.
Anonymous usage statistics
To improve the website, we record anonymously on our own server how it is used: which website or search engine you came from, which pages you view, how long you spend on each section, how far you scroll, which links and buttons you click, what you search for on the site, the criteria you choose in the material selector, and how far you get in the quote form and whether it was sent (not what you type into it). We also record the country (derived from your browser’s time zone and language settings), the type of device, and the type of operating system and browser.
No cookies are used for this, and nothing is stored in your browser. We do not store your IP address: our server combines it with your browser information into a random code that is valid for one day only, so that the pages you view on the same day can be linked. The key used for this code changes every day and old keys are not kept, so the code cannot be traced back to your IP address. These records are not linked to your name, email address or quote requests, are not shared with anyone, and are used only in aggregate. If your browser sends a Do Not Track or Global Privacy Control signal, we record nothing.
Legal basis: Art. 6(1)(f) GDPR (our legitimate interest in understanding how the website is used, so that we can improve it).
What is stored in your browser
- Your settings: language, light or dark display, metric or US customary units, grade designations.
- Your RFQ list (grades you added) and, after you send a quote request, your contact details, so the form is filled in next time.
- After you leave your email address for a datasheet: a cookie (ds_access, one year) so we don’t ask again on this device.
These are needed for functions you use; none of them track you. You can delete them at any time in your browser settings.
Who receives your data
Our staff who handle your request, and the providers that host this website and deliver emails and internal notifications. We do not sell your data or pass it on for advertising.
Where your data is processed
We are based in China. The website and the data you send us are kept on a server in Hong Kong, and pages are delivered through Alibaba Cloud’s content delivery network (CDN) from a data centre near you. Our staff in mainland China access and process the data there. Neither Hong Kong nor mainland China is covered by an EU adequacy decision. We process your data there because that is where we answer your request from.
How long we keep it
- Quote requests and attachments: three years from when you send them, then deleted. If a request leads to an order, we keep the order documents as long as commercial and tax law requires.
- Datasheet download records: until you object or ask us to delete them.
- Anonymous usage statistics: 13 months, then deleted.
- Server logs: only as long as needed for security.
Your rights
You can ask us for access to your data, to correct or delete it, to restrict its use or to receive a copy of it, and you can object to its use — in particular for emails about our products (Art. 15–18, 20 and 21 GDPR). Write to info@kochlin.com. You also have the right to complain to a data protection authority, for example the one in your country.
We do not make automated decisions or create profiles about you.
Changes
