YiRadar website notice

Privacy and inquiry data

This notice explains the business information YiRadar asks for when a visitor starts an engineering or commercial conversation. YiRadar is the public brand of Beijing Yijianda Technology Co., Ltd.; its operational engineering team is based in Shenzhen, China. For questions about this notice or a data request, write to wangzjpku@gmail.com.

Information requested for an inquiry

The contact, RFQ, and sample forms ask for a name, business email, company, country or region, preferred reply language and channel, and a project message. RFQ and sample requests also ask for a product or application reference and expected quantity. A visitor who chooses WhatsApp or WeChat provides the number or ID to use for the requested reply channel.

The inquiry route also receives the landing page, referrer, campaign parameters, browser user-agent, and a one-way IP-derived anti-abuse value. These data help route the request, understand its source, and protect the form from automated abuse. Please do not include medical records, special-category personal data, or confidential third-party files in an initial website inquiry.

Why the information is used

• To respond to an engineering, sample, RFQ, PCB, embedded-integration, or batch-development request.
• To understand the application, project timing, target market, quantity range, and requested reply method before assigning the appropriate review.
• To protect the form, prevent spam, keep a basic record of consent, and investigate an apparent misuse of the website.
• To perform a confirmed commercial or engineering engagement only under the terms agreed for that engagement.

Access and sharing

Inquiry information is intended for YiRadar personnel who need it to respond or evaluate the project. A confirmed program may require limited project information to be shared with an appropriate manufacturing partner or other service provider, but only when that is necessary for the agreed work. YiRadar does not publish inquiry details, sell them as a data product, or treat an inquiry as permission to expose a buyer’s project.

Website services and analytics

Public pages are hosted on Cloudflare Pages. Inquiry requests are checked with Cloudflare Turnstile, rate-limited in a Cloudflare Worker, and stored in a Cloudflare D1 database whose primary location is set to Asia Pacific. Cloudflare processes the technical data needed to deliver and protect those services. Optional website analytics are not initialized until a visitor gives an explicit analytics choice and a measurement configuration is active. Essential website functions may still use browser storage needed to retain that analytics preference.

Your request

To ask about the information associated with a business inquiry, request a correction or deletion, or withdraw a marketing follow-up request, email wangzjpku@gmail.com from the relevant address and describe the request. YiRadar will review the request against the applicable law, project commitments, and any record-retention or security obligation that applies.

Retention and safeguards

YiRadar normally retains an inquiry for up to 24 months after the last meaningful contact so that it can respond to the request, maintain a commercial record, and protect the service. It may retain limited information longer where a law, security investigation, or signed project obligation requires it. Access is limited to people and service providers who need the information for the purposes described above. Before actively marketing in a jurisdiction with additional notice, representative, or cross-border-transfer requirements, YiRadar will complete the relevant local review and update this notice where needed.
