1. Who we are

This website, www.ibestdevice.com, is operated by Shenzhen Layjun Technology Co., Ltd. (深圳市雷军科技有限公司), a company registered in Shenzhen, Guangdong, People's Republic of China, trading under the brand name Layjun Welder.

For the purposes of the EU General Data Protection Regulation (GDPR), the UK GDPR and similar laws, Shenzhen Layjun Technology Co., Ltd. is the data controller for personal data collected through this website.

Contact for all privacy matters: sales@ibestdevice.com · +86 134 2309 4186 · WhatsApp.

2. What we collect

We only collect what we need to answer a commercial enquiry and fulfil an order.

  • Enquiry and quotation data — your name, company name, business email, telephone or WhatsApp number, country, and the technical details of your application (wire type, gauge, thermocouple type, target throughput, drawings or photos you choose to send).
  • Order and shipping data — billing and delivery address, VAT / tax identification number, customs broker contact, and the consignee name for the shipment.
  • Correspondence — the content of emails, WhatsApp messages and video call notes exchanged with our sales and engineering team.
  • Technical data — IP address, browser type, device type, referring page and pages viewed, collected in aggregate by our hosting provider for security and performance monitoring.
  • Preferences stored in your browser — your selected language and display currency. These stay on your device and are never transmitted to us.

We do not collect payment card numbers. Orders are settled by bank transfer or by a payment provider's own secure checkout, where the provider is the controller of your card data. We do not run behavioural advertising or cross-site tracking on this site.

3. Why we use it

  • To answer your enquiry and prepare a quotation, including engineering review of any sample or drawing you send.
  • To perform the contract of sale — order processing, production, testing, export documentation, shipping and customs clearance.
  • To provide after-sales support, warranty service and spare parts.
  • To meet legal obligations, including export control, tax, accounting and customs record-keeping requirements in the People's Republic of China.
  • To protect the website against abuse, spam and fraud.
  • To send you occasional product or technical updates — only where you have asked for them, and always with a one-click unsubscribe.

5. Cookies and local storage

This site sets no advertising or analytics cookies. It uses only essential browser storage:

  • wp_lang — remembers your chosen display language.
  • wp_currency — remembers your chosen display currency.

Both are stored in your browser's localStorage, never sent to our servers, and can be cleared at any time from your browser settings. Because they are strictly functional, no cookie consent banner is required under the ePrivacy Directive.

6. Who we share it with

We do not sell, rent or trade personal data. We share it only with parties who help us deliver the goods or the law requires:

  • Freight forwarders, airlines, shipping lines and couriers — consignee name, address, telephone and customs data, strictly to move your shipment.
  • Customs authorities and licensed brokers — in the destination country and in China, for import and export clearance.
  • Banks and payment providers — for payment verification and fraud prevention.
  • Our hosting provider — which stores the website and its access logs.
  • Professional advisers — auditors, insurers and lawyers, under confidentiality.

Where a distributor or service partner in your country handles your enquiry, we will name that partner to you before sharing anything, and share only the data needed to serve you.

7. International transfers

We are based in the People's Republic of China, so your enquiry data will be transferred to and processed in China. Where the GDPR applies, transfers rely on the Standard Contractual Clauses approved by the European Commission, together with technical and organisational measures such as encryption in transit (TLS), access control and confidentiality undertakings.

Where your freight forwarder or distributor is in your own country, the relevant shipping data stays in that country and is shared with the carrier directly.

8. How long we keep it

  • Unsuccessful enquiries — 24 months, then deleted.
  • Quotations — 36 months, so we can honour a repeat price and trace the technical specification we quoted.
  • Order, shipment and warranty records — 10 years, which is the period Chinese tax and customs law requires and our spare-parts commitment runs to.
  • Marketing subscriptions — until you unsubscribe, then suppressed so we do not re-add you.

9. Your rights

Depending on where you live, you may have the right to:

  • access a copy of the personal data we hold about you;
  • have inaccurate data corrected;
  • ask us to delete data we no longer need;
  • object to or restrict processing based on legitimate interests;
  • receive your data in a portable machine-readable format;
  • withdraw consent for marketing at any time.

Email {EMAIL} and we will respond within 30 days. We will ask you to verify your identity first. If you are in the EU or UK you also have the right to complain to your national supervisory authority.

California residents: we do not sell or share personal information as those terms are defined by the CCPA / CPRA, and we do not use it for cross-context behavioural advertising. You may still exercise the rights above.

10. Security

The site is served over HTTPS with HSTS. Access to enquiry data is restricted to the sales and engineering staff who need it, protected by individual accounts and two-factor authentication. We keep backups encrypted, and we delete or anonymise data when the retention period ends. No system is perfect, so if a breach ever affects your rights we will notify you and the relevant authority without undue delay.

11. Children

This is a business-to-business industrial website. It is not directed at children and we do not knowingly collect data from anyone under 16. If you believe a child has sent us personal data, contact us and we will delete it.

12. Changes to this notice

We update this notice when our practices or the law change. The "last updated" date at the top always reflects the current version, and material changes will be flagged on this page.
