Qingze Systems
Privacy policy
Last updated: 7 November 2026
This website, qingzesystems.com, is operated by Dongguan Qingze Environmental Protection Technology Co., Ltd., trading under the Qingze Systems brand. This policy explains how information is handled when you browse the website, send an enquiry or choose optional visitor statistics.
1. Enquiries and business communication
When you choose to contact us, we process the information you provide to answer questions, assess equipment requirements, prepare quotations and follow up on the enquiry. Depending on the form, this may include your name, company, contact details, country or region, water source, application, water demand, preferred model and project message.
Please provide only information needed for your enquiry. Do not include passwords, identity-document numbers, bank details or unrelated sensitive information in the message.
Website enquiries are saved in website records and sent to our business email. Records may include relevant page paths, referring websites and campaign source labels to help us understand the enquiry context. Your enquiry text and contact details are not sent as Google Analytics event content.
2. Website access and security
Website hosting services produce access and error logs, which may include IP addresses, request times, page paths, browser information and response statuses. These records support website operation, troubleshooting and security.
Form handling includes measures against duplicate submissions and frequent submissions in a short period. These processes are separate from optional visitor analytics.
3. Optional analytics and your choice
We use Google Analytics 4 (GA4) to understand page visits, traffic sources, device or browser information, and use of enquiry and contact options. This helps us improve website content and service.
The optional analytics service loads only after you choose to allow it. Rejecting optional analytics does not prevent you from browsing the website or submitting an enquiry.
GA4 may use cookies, such as cookies whose names begin with _ga, and other identifiers. Your browser also stores your analytics choice and short-term session information. Page addresses sent by this website to analytics have query parameters removed, and event content is limited. We do not intentionally send form names, contact details or messages as analytics event parameters.
This website currently disables ad personalisation and Google signals, and does not use these features to build personalised advertising audiences. Analytics data may be linked to our Google Ads account for website metrics and enquiry-submission statistics. A recorded submission is not evidence of a completed sale.
Optional Microsoft Clarity session replay
After you allow optional analytics, we also use Microsoft Clarity to understand page browsing, scrolling, clicks and enquiry steps. These behaviour records are sent to Microsoft and may use cookies such as _clck and _clsk to link visits. Strict masking is enabled for page text and form entries; we do not intentionally send enquiry messages or contact details as custom events. Administrative and explicitly marked test visits are excluded.
Clarity does not load before your permission or when you reject optional analytics. Use Analytics settings to withdraw permission and stop subsequent optional collection. Withdrawal does not automatically delete records already processed. Records are subject to Clarity retention and access controls. See the Microsoft Privacy Statement and contact sales@qingzesystems.com about relevant records.
Change your analytics choice
On pages that offer optional analytics, use the analytics settings control near the bottom of the page to reject analytics and stop subsequent optional collection. This also clears GA cookies that the website can identify. Withdrawing consent does not automatically delete data Google has already processed.
You can also remove cookies and website storage in your browser; a later visit may require a new choice. The website does not start optional analytics when it detects supported Do Not Track or Global Privacy Control signals.
For Google’s own data handling and additional controls, see How Google uses information from sites or apps that use its services, the Google Privacy Policy and the Google Analytics opt-out browser add-on.
If you allow analytics, this website also keeps aggregate counts by date and page to help identify missing analytics data. These summaries do not create individual browsing profiles or contain names, email addresses or IP addresses. Our hosting provider may still process normal connection logs. Summaries show the latest 14 days and are periodically cleared. No new diagnostic records are added after analytics is rejected or withdrawn.
4. Service providers and external platforms
Hosting, email-delivery and analytics providers process information as needed to provide their respective services. Their infrastructure may be outside your country or region. We arrange necessary data handling in accordance with applicable requirements and do not publish your enquiry.
If you follow a website link to WhatsApp, WeChat, LinkedIn or another external platform, your interaction with that platform is also subject to its own privacy policy. This policy does not replace those platform policies.
5. Retention and protection
We retain information according to the needs of enquiry handling, quotation discussions, contracts, after-sales service and applicable record-keeping requirements. Enquiry records do not currently have a uniform automatic deletion period. We review whether continued retention is necessary and delete or anonymise information that is no longer needed and does not have to be retained by law. You can request deletion using the contact details below.
Analytics data is handled according to the GA4 property’s retention settings. Server and email records are managed according to the relevant services and business needs.
We use measures such as access restrictions to protect information. No method of internet transmission or storage can guarantee absolute security.
6. Your requests and our contact details
Subject to applicable law, you may ask about information we hold relating to you, request correction or deletion, or withdraw your optional analytics choice.
Email sales@qingzesystems.com with your request and enough information to identify the relevant enquiry. We may need to verify your connection to the records to avoid disclosing information to an unrelated person. Information that must be retained by law may not be deleted immediately.
