Privacy Policy
Last updated: 28 October 2026
Wenzhou Ronder Compressor Valve Technology Co., Ltd. (“we”, “us” or “RONDER”) provides product information and business enquiry channels through the RONDER website. This policy explains how we collect, use, retain and protect personal information relating to website visitors and business contacts.
Our Content Use Policy separately explains the permitted discovery and use of approved public marketing and technical knowledge content. It does not apply to personal information, enquiry submissions, or other non-public materials.
1. Who controls your information
The controller is Wenzhou Ronder Compressor Valve Technology Co., Ltd., No. 52 Xingping Road, High-Tech Industrial Park, Puzhou Subdistrict, Longwan District, Wenzhou, Zhejiang, China. Privacy questions and rights requests may be sent to sales@ronder-valve.com and are handled by our management.
2. Information we process
When you contact us by email, Telegram, WhatsApp or WeChat, we may process information you provide, including your name, company or organisation, email address, country or region, telephone or WhatsApp number, Telegram or WeChat nickname or account information, product category, compressor manufacturer and model, medium or gas, operating parameters, enquiry message and attachments you choose to provide.
The website may store your chosen language on your device to improve later navigation. We do not use the website for advertising tracking or behavioural profiling.
We use Umami Cloud only to count aggregate contact interactions. A count is sent when a visitor clicks an email, WhatsApp or Telegram contact link, or opens the WeChat QR-code dialog. The only custom event properties are the site language (en, zh or ru) and placement (header, footer, contact_page, product_page or floating_bar).
The contact-interaction analytics script does not read visitor input. The website does not add enquiry content, customer contact details, email addresses, link destinations, URL query parameters, browser language, screen dimensions, referrer information, a visitor identifier or device-fingerprint data to the analytics payload. It does not use these events for behavioural profiling, sends no ordinary page-view events, and does not store an identifier returned by Umami.
Umami Cloud processes the network and browser request information needed to provide its HTTPS service, including IP address and user-agent data, and may derive an anonymous session identifier under its own service operation. Our analytics account is configured for the EU (Frankfurt) region; its free plan retains analytics data for six months. Contact interaction statistics summarize how often the website’s contact controls are used.
3. Why we process it
- to receive, confirm and respond to product or technical enquiries;
- to understand the compressor, valve, duty and complementary wear-part requirements involved;
- to maintain follow-up business and technical communication records;
- to measure website use and improve public content and contact entry points;
- to prevent abuse and security incidents; and
- to meet applicable legal duties and respond to privacy rights requests.
We do not use enquiry information for unrelated marketing subscriptions or automated decision-making without obtaining any additional consent required by law.
4. Legal basis and required information
Where consent is required, we process enquiry information on the basis of your consent. Where permitted by applicable law, processing may also be necessary to take steps at your request before entering into a contract, to respond to a legitimate business request, or to comply with a legal obligation. Please provide contact details we can use to respond to your request.
5. Information storage and recipients
We may retain the contact details, company information and technical details you provide by email, Telegram, WhatsApp or WeChat as internal business records, as needed to handle enquiries, support technical communication and follow up with customers. Only RONDER staff who need these records to handle your enquiry as part of their work can access them. We may use service providers for security checks, internal collaboration or other necessary services, subject to appropriate protection requirements. We do not sell your personal information or disclose it to unrelated third parties unless the law requires it, it is needed to protect legal rights, or you authorise it.
6. International enquiries and other communication channels
We accept business enquiries from mainland China and other countries and regions. If you contact us by email, Telegram, WhatsApp, WeChat or another third-party channel, that provider may process your message in other countries under its own terms.
7. Retention
We retain enquiry information for one year from receipt of the enquiry to handle enquiries, support technical communication, follow up with customers, and retain necessary business records. We will delete or anonymise information when the purpose has ended and no legal retention duty applies. We review access permissions and retained records at least once a year.
8. Your rights
Subject to applicable law, you may request access to, a copy of, correction, completion or deletion of your personal information; restriction of or objection to certain processing; withdrawal of consent; or an explanation of our processing rules. Withdrawing consent does not affect processing already carried out lawfully before withdrawal. We may verify your identity before acting on a request to protect the information involved.
9. Security
We use access control, encrypted transmission and internal procedures to protect personal information from unauthorised access, disclosure, alteration, loss or misuse. If a personal information incident occurs, we will take the remedial and notification steps required by law.
10. Children
This website is intended for industrial and business customers and is not directed to children under 14. If we learn that a child’s personal information has been collected inadvertently, we will take the deletion or other action required by law.
11. Policy changes
We will update this policy when material changes are made to processing purposes, information categories, recipients, retention rules or applicable requirements, and will obtain renewed consent where required. The date at the top identifies the current version.
