Effective date：2026-09-01Version：1.0The Simplified Chinese version of this page prevails

This notice explains how 内蒙古优讯通讯有限责任公司, which operates the uxtrade.net website and the "优讯通讯" WeChat Mini Program, approaches the protection of children's personal information, what we do in practice, and what rights guardians have. Our services are intended for business customers and adult individual users, not for minors. This page states honestly what age-verification capability we currently have and do not have, and gives guardians usable channels. It expands Section 10 of the Privacy Policy and applies together with the Privacy Policy and the Terms of Service.

1. Scope of this notice

This notice applies to all stages at which the uxtrade.net website (including its mobile web pages and share pages) and the "优讯通讯" WeChat Mini Program (together, the "Platform") may come into contact with the personal data of minors.

This notice is a specialised supplement to the Privacy Policy. The Privacy Policy explains what information we collect, how we use it and to whom we disclose it; this notice addresses only the parts concerning minors. Where this notice and the Privacy Policy differ on matters concerning minors, this notice prevails.

2. Age thresholds and legal basis

Jurisdictions define "child" and "minor" differently. We apply the strictest of the following standards:

China — under 14 is a child. Under Article 31 of the Personal Information Protection Law of the People's Republic of China and the Provisions on the Network Protection of Children's Personal Information, processing the personal information of a minor under 14 requires the consent of a parent or other guardian, and a dedicated rule for processing children's personal information must be formulated. This notice is that dedicated rule.
EU — under 16 for information society services. Under Article 8 of the General Data Protection Regulation (GDPR), where information society services are offered directly to a child, the consent of a child below 16 must be given or authorised by the holder of parental responsibility; Member States may lower that age by law, but not below 13.
United States — under 13 under COPPA. If you are located in the United States and the Children's Online Privacy Protection Act (COPPA) applies, we make no claim of certification or compliance; please have your guardian contact us at the email below first, and we will handle the matter on a case-by-case basis as local requirements demand.
Other jurisdictions. If your country or region has dedicated legislation on children's personal information, the guardian should contact us first and we will handle the request in accordance with local law.

We adopt a strict approach: users under 16 must use these services with the consent and accompaniment of a parent or other guardian, and children under 14 should not register an account, submit a quotation request, file a repair request or upload any information on their own — a guardian must submit or operate on their behalf.

3. Our basic position: the Platform is not directed at minors

The principal business of the Platform and the "优讯通讯" WeChat Mini Program is integrated low-voltage security and communications systems, including solution design, equipment supply, installation and after-sales maintenance. Our customers are business clients and adult individual users. The product and solution information on the Platform serves procurement, engineering and operations scenarios and is not content aimed at children.

We do not offer products or services to minors and do not target minors as users;
The Platform has no children's content channel, cartoon section or story section;
The Platform has no games, virtual items, virtual gifts, tipping or in-app purchasing features;
The Platform has no social networking, dating, livestreaming, community posting or stranger-interaction features aimed at minors;
We do not serve advertising and have integrated no third-party advertising or cross-site behavioural tracking SDKs.

Our product positioning therefore does not encourage minors to use the Platform. The purpose of this notice is to explain how we handle information in the event that a minor uses the Platform incidentally or a guardian acts on their behalf.

4. Where minors' personal data may be involved

We do not screen users' ages in advance, so the following entry points can indeed receive a minor's personal data if a minor operates them personally. We describe each honestly.

4.1 Website account registration and login

When you register an account on uxtrade.net we collect your name, mobile number, email address and login password. Passwords are stored in irreversible hashed form; we neither keep nor can restore your plaintext password. On login we verify the email and password hash and issue a login credential to your browser so the server can recognise your session.

A limitation we must disclose honestly: the registration form has no date-of-birth or age field, and we perform no age verification. In other words, if a minor fills in the form themselves, the system will not technically identify or block them. We address this through our terms of use, the guardian notices in this document and post-hoc deletion, not through an upfront age gate.

4.2 Quotation request and contact form

The "Get a quote / Contact us" form collects name, telephone, email, company name and a free-text description of requirements, and it may be submitted anonymously without logging in. The form also contains a human-invisible "honeypot" field used solely to detect automated spam submissions; ordinary users never fill it in.

If a minor fills in the form in their own name, their name and contact details will be stored; if a company name is entered, business information may also be involved. A guardian should complete the form on the minor's behalf, or consent should be obtained first.

4.3 Online repair requests and online enquiries

An online repair request collects a contact name, contact telephone, equipment information and a fault description, and generates a query link containing a random token; the online enquiry window records the nickname you use and the content of your messages. Fault descriptions and photographs can sometimes contain information about a home, a workplace or individuals. A guardian should submit on the minor's behalf, and information unrelated to the business should be omitted from the description.

4.4 WeChat Mini Program login and mobile-number authorisation

When you log in inside the Mini Program, WeChat returns to us a user identifier isolated per Mini Program (openid), and we create a Mini Program account on that basis. If you use the WeChat nickname and avatar capability, we store the nickname and avatar address you confirm and submit; if you tap "Get mobile number" and complete WeChat's quick mobile-number verification, we receive and store that mobile number. Whether to authorise is your decision.

A WeChat account may itself be used by a minor, and WeChat maintains its own separate protection rules for minors, which prevail on the WeChat side. We create the account from the openid returned by WeChat and perform no additional age verification.

4.5 Uploaded images and files

Images you provide when changing your avatar or communicating with us (for example photographs of a fault site or drawings) are uploaded to and stored in our object storage. Photographs may contain the faces or dwelling identifiers of a minor, family members or third parties. Please mask such details before taking and uploading pictures.

4.6 Server access logs

To keep the site available and secure and to prevent abuse, our servers automatically record access logs containing the IP address, requested path and query parameters, User-Agent, referring page (Referer) and access time, and we perform coarse-grained IP geolocation (country, province, city, carrier) for security policies. Access logs are not collected specifically about minors, but are recorded technically in any event. Logs are collected automatically and visitors cannot opt out of providing them; the only way to refuse is to stop visiting the site.

5. What we do not do

Whether information comes from an adult or a minor, we undertake the following:

We do not actively or intentionally collect children's personal data, and we design no feature or campaign for the purpose of obtaining it;
We do not use children's personal data for profiling, personalised recommendations or advertising (the Platform does not serve advertising in any case);
We do not use children's personal data for automated decision-making, including automated pricing discrimination or automated refusal of service, or other decisions producing legal or similarly significant effects;
We do not sell children's personal data to third parties and do not share it for third-party marketing purposes;
Children's personal data is stored and processed only within China, and retained only for the shortest period necessary to achieve the purpose of the service; the retention periods are set out in the "Appendix: Unified Legal Provisions" at the end of this page and are consistent with Section 6 of the Privacy Policy;
Where necessary to provide the service, entrusted processors act only on our instructions; the list of processors appears in the "Appendix: Unified Legal Provisions".

6. Guardians' rights and how to exercise them

If you are the parent or other guardian of a minor, you hold the following rights in respect of that minor's personal data and may exercise them on the minor's behalf:

Access and copy: request access to and a copy of the minor's personal data we hold, such as account information, quotation requests, repair records and Mini Program account information.
Rectification and completion: request correction of inaccurate data or completion of incomplete data.
Erasure: request deletion of the minor's personal data.
Withdrawal of consent: withdraw consent you previously gave, including consent to mobile-number authorisation and to the use of your WeChat nickname and avatar. Withdrawal does not affect processing carried out on the basis of consent before withdrawal.
Account closure: request closure of the minor's website or Mini Program account; after closure we delete or anonymise the account information.

Channel: please email our legal and privacy mailbox at sales@uxtrade.cn, ideally with a subject line such as "Minor's data — access / rectification / erasure / withdrawal of consent / account closure". To help us locate the records, please indicate the identifying details involved, such as a mobile number, email address or openid.

Documents to provide: to confirm that you are entitled to act on the minor's behalf and to prevent others from obtaining the information, we need (1) proof of guardianship (household register, birth certificate or custody document) and (2) proof of your own identity. These documents are used only for this verification; after verification we will delete or securely hold them as you request.

Time limit: after receiving your request and complete documents, we generally reply with the outcome within 15 business days. If a case is complex and requires more time, we will tell you the reason and the expected timeframe.

On erasure: where erasure is involved we delete or anonymise the data so that the minor can no longer be identified. The minimum records that laws and regulations require us to keep (for example concluded contracts or logs subject to statutory retention) are excepted; for those we restrict the scope of processing and delete them once the period expires.

7. What happens if we discover unlawful collection

If we discover that we have collected a child's personal data without verifiable parental consent, we will:

immediately stop any further processing of that data and suspend related automated workflows;
delete or anonymise the data as soon as possible so that the child can no longer be identified;
where necessary, notify the entrusted processors and the WeChat Mini Program platform involved in the processing and require them to do the same;
where necessary, inform you of how the matter was handled through a notice on this page or via the contact details you provided.

Guardians may also write to us directly to request deletion, without waiting for us to discover the issue. We will not restrict or reduce our service to you because you made such a request.

8. Safety advice for minors and guardians

In quotation requirements, repair descriptions or enquiry messages, do not enter ID card numbers, bank card numbers, school names or classes, home addresses, door access codes or other information unrelated to the business;
Before uploading fault-site photographs or drawings, mask faces, house numbers, licence plates and staff badges and similar identifying marks;
If a minor genuinely needs to use the Platform, they should do so accompanied by a guardian, who should complete and submit the forms on their behalf;
Guardians should manage the login state and WeChat authorisations on shared household devices, logging out promptly and revoking unnecessary authorisations;
Do not disclose account credentials to others and do not share accounts; contact us immediately if you notice anything unusual about an account;
If you receive unsolicited messages in our name asking for credentials, verification codes or a transfer of funds, verify them using the contact details at the end of this page.

9. Limitations and planned improvements

We state the current position honestly and make no compliance claim beyond our actual capability:

The Platform currently has no age assurance mechanism, collects no date of birth and runs no identity or age verification process;
The Platform currently has no child-specific self-service information management entry point and no self-service lookup or deletion button for guardians;
We currently rely on three things to address minors' information: clear notice in the terms of use, the guardian notices and mailbox channel in this document, and post-hoc deletion once an issue is discovered;
We hold no COPPA certification and participate in no children's privacy compliance certification programme;
If you consider that the Platform needs a stricter age gate, more prominent notices about minors, or more convenient self-service tools for guardians, please write to sales@uxtrade.cn. We will assess the product and technical conditions and build the entry point into the pages once conditions allow.

10. Changes, contact and reference to the Appendix

For material changes to the rules on processing minors' information, we will update the version number and effective date on this page and give advance notice through a prominent on-page notice; where necessary we will seek the guardian's consent again.

Appendix 2. Processing activities, categories of data and legal bases

The list below sets out the processing activities we actually carry out, the categories of data involved and the corresponding legal bases (Article 6(1) GDPR).

Account registration and sign-in — Data: name, mobile number, email address, password hash, session identifier. Legal basis: necessary for the performance of the service contract you request (Article 6(1)(b)); protecting account and system security is our legitimate interest (Article 6(1)(f)).
Quotation and contact forms — Data: name, telephone number, email address, company name, description of requirements. Legal basis: necessary to take steps at your request prior to entering into a contract (Article 6(1)(b)). The form also contains a hidden "honeypot" field that only detects automated spam submissions; genuine visitors never fill it in and it is not your personal data.
Quotations, contracts and after-sales reconciliation — Data: customer name, contact telephone, email address, company name, project or requirement description, quotation line items and amounts, share token. Legal basis: performance of a contract (Article 6(1)(b)); after-sales and warranty traceability is our legitimate interest (Article 6(1)(f)).
Online repair requests and online enquiries — Data: contact person, telephone number, equipment and fault description, enquiry nickname and message content. Legal basis: performance of a contract or steps taken at your request (Article 6(1)(b)).
WeChat Mini Program sign-in, nickname/avatar and mobile number authorisation — Data: sign-in code, openid, the nickname and avatar URL you confirm, mobile number. Legal basis: your consent (Article 6(1)(a)). You may withdraw your consent at any time; withdrawal does not affect the lawfulness of processing carried out on the basis of consent before withdrawal.
Sending quotations and contracts by email — Data: recipient email address, subject line, body and attachments. Legal basis: performance of a contract (Article 6(1)(b)).
Access logs and security protection — Data: IP address, request path and query parameters, request method, User-Agent, referrer, access time, and coarse IP-derived country, province/city and network operator. Legal basis: safeguarding service and network security and preventing attacks and abuse is our legitimate interest (Article 6(1)(f)); it also falls within the grounds permitted under Article 13 of the Personal Information Protection Law of the People's Republic of China, as further specified by Chinese law.
Article popularity statistics (de-identified) — Data: a de-identified identifier consisting of the first 16 characters of a salted hash of the visitor's IP address. Legal basis: measuring content popularity is our legitimate interest (Article 6(1)(f)). The identifier contains no plaintext IP address and is not linked to any account.
Content and asset management — Data: articles, product information, cases and illustrations that we write, photograph, generate or use under licence (some illustrations are generated by AI from text prompts). Legal basis: performance of a contract and our freedom to conduct business (Article 6(1)(b) and (f)).
Compliance with legal obligations — Data: the minimum scope required by the competent authorities (filing information, material lawfully requested). Legal basis: legal obligation (Article 6(1)(c)).
Handling reports and infringement complaints — Data: complainant identity and contact details, evidence of rights, URL of the content complained about. Legal basis: legal obligation and our legitimate interests (Article 6(1)(c) and (f)).

If we later introduce non-essential cookies or marketing communications, we will obtain your consent first and list them here. We do not subject you to automated decision-making that produces legal effects or similarly significantly affects you (for example automated price discrimination or automated refusal of service).

Appendix 3. Processors and third-party recipients

We engage the following third parties on a data-minimisation basis. They process data on our instructions and act as processors within the meaning of Article 28 GDPR. Each "purpose" arises only when the relevant function is actually used; it does not occur on every visit.

Qiniu Cloud (object storage and content delivery): processes images, audio/video and text asset files, including avatars and on-site fault photographs that you upload. Purpose: asset storage and accelerated delivery.
DeepSeek (api.deepseek.com; text generation and translation): processes text we submit, which may include quotation copy, product information, article drafts and image prompts, together with the project and requirement descriptions, company names and product specifications contained in them. Purpose: text generation, material drafting and multilingual translation.
Alibaba Cloud Tongyi Qianwen / DashScope (including Qwen-Image and Tongyi Wanxiang; image generation): processes the text prompts we submit. Purpose: generating illustrations for the website and articles. Prompts are normally produced by a text model from internal material and generally do not contain your contact details.
Tencent WeChat (Mini Program sign-in, fast mobile number verification, JS-SDK sharing): processes the sign-in code, openid, the nickname and avatar you authorise, the result of fast mobile number verification and the current page URL required for JS-SDK signatures. Purpose: identity within the Mini Program and sharing capabilities inside WeChat.
Tencent WeCom (internal customer-service alerts): processes an event notification when a new online enquiry arrives (it does not contain the full conversation). Purpose: enabling our staff to respond promptly.
The SMTP email service provider we configure (email delivery): processes the recipient address, subject line, and the body and attachments of quotations or contracts. Purpose: sending you quotations, contracts and notices.
IP geolocation services (ipapi.co, ip-api.com) and a local IP database (ip2region): process the visitor's IP address, or country and region information derived from it. Purpose: identifying the region of origin, selecting the site language and applying security policies.
CDN / reverse proxy and server hosting services: host the website, database and backups and process access request logs. Purpose: providing network connectivity, availability and disaster recovery.

Apart from the processors listed above, situations where you have given consent, and situations required by laws or by a lawful request of a judicial or administrative authority, we do not provide your personal information to any third party. We do not sell your personal information and we do not share it for third-party advertising purposes. We have not integrated any third-party advertising or cross-site behavioural tracking SDK.

Appendix 4. Cross-border transfers

Your personal information is primarily stored and processed on servers located in the territory of the People's Republic of China; static assets are stored in a domestic object storage service (Qiniu Cloud).
If you access or use our services from outside China, your personal information will be transferred to and processed in China. Such transfers are subject to Article 44 et seq. GDPR. We implement contractual and organisational safeguards for those transfers in accordance with applicable law and will put in place the required transfer mechanisms where the law so requires.
Where we use service providers outside China to process text or prompts, the relevant text is transferred to those providers' systems. We submit only the text necessary for the processing purpose and seek to avoid submitting sensitive personal information unrelated to our business.
Because using our services necessarily involves transferring data to China, please do not submit personal information if the law of your jurisdiction does not permit such a transfer. You may still browse the public content anonymously.

Appendix 5. Retention periods

Account information (website membership and WeChat Mini Program): for as long as the account exists; deleted or anonymised after account closure.
Enquiries, quotations, contracts and correspondence: for the duration of the service relationship and for 3 years afterwards (needed for after-sales support, warranty, reconciliation and limitation defences).
Repair records: 1 year after the warranty period expires.
Access logs (including IP address, User-Agent, request path and time): no longer than 6 months, after which they are deleted or aggregated into statistics that no longer contain IP addresses.
De-identified identifiers used for article view counting: no longer than 12 months.
Report and infringement complaint materials: 1 year after the matter is closed, for review and dispute handling.
Records we must keep by law (for example concluded contracts, accounting vouchers, logs that authorities require us to retain): retained for the period prescribed by law, which may be longer than the periods above.

Once a retention period expires we delete or anonymise the data so that it can no longer be linked to you. These periods reflect our current system implementation and business needs and do not exhaust every situation required by law; where a longer retention period applies to a particular item of data, we will explain the specific basis.

Appendix 6. Your rights

To the extent provided by applicable law, you have the following rights in relation to your personal information. The methods of exercise, supporting documents and response times are set out in the Data Subject Rights and Account Closure Notice.

Information and access: to learn whether we process your information and to obtain a copy.
Rectification: to have inaccurate or incomplete information corrected or completed.
Erasure: to have your personal information deleted in the circumstances provided by law.
Restriction of processing: in certain circumstances, to require us to store the data without processing it further.
Objection: to object to processing we carry out on the basis of legitimate interests.
Data portability: to receive the information you provided to us in a structured, commonly used, machine-readable format.
Withdrawal of consent: to withdraw consent at any time, without affecting the lawfulness of processing before withdrawal.
Not to be subject to solely automated decision-making.
Complaint: you have the right to lodge a complaint with the personal data protection supervisory authority in your country or region (for example a national data protection authority in the EU/EEA, the UK Information Commissioner's Office, or the Cyberspace Administration of China and its local offices). If you contact us first at sales@uxtrade.cn, we will do our best to resolve the matter directly.

Exercising these rights will not lead us to refuse you service or treat you in a discriminatory way. To protect your information, we may verify your identity before acting on a request.

Appendix 7. Security measures

We apply technical and organisational measures appropriate to the risk. The measures listed below are all actually in place on this site; we do not list measures we have not implemented.

Encryption in transit: the site is served over HTTPS and sends HSTS (Strict-Transport-Security) together with X-Content-Type-Options, Referrer-Policy, Permissions-Policy and a report-only Content Security Policy (CSP Report-Only).
Password protection: account passwords are stored as salted bcrypt hashes; we neither store nor can recover your plaintext password.
Role separation: administrator and ordinary member roles are separated, and the admin interface and member interface authenticate independently. Administrative write operations validate the request origin (Origin/Referer) to reduce cross-site request forgery risk.
Anti-abuse: sign-in, registration, enquiry and mobile number binding endpoints are rate limited; malicious IP addresses can be blocked.
Access logging: IP address, User-Agent, request path and time are recorded for security auditing, troubleshooting and rate limiting.
Least privilege: assets are stored in object storage with restricted access paths, and administrative accounts are limited to authorised personnel.

There is no zero-risk solution for transmission over the internet or for storage. We do not promise absolute security in all circumstances. If a personal data security incident occurs, we will take remedial measures promptly in accordance with the law and, where the law requires it, inform you by a notice on this site or through the contact details you provided, describing the nature of the incident, its possible impact, the measures taken and the steps you can take to protect yourself.

Appendix 8. Changes, effective date and version

Current version: 1.0; effective date: 2026-09-01.
How we notify changes: we update the version number and effective date on this page and publish them here. For material changes — such as an expansion of the scope of collection, a change in the recipients of personal information, a change in cross-border transfer arrangements, or a change in the way you can exercise your rights — we will give advance notice by a prominent notice on the site and, where necessary, ask for your consent again.
Previous versions are available on request.

Appendix 9. Governing law and dispute resolution

The formation, validity, interpretation and dispute resolution of the agreements and policies on this site are governed by the laws of the mainland of the People's Republic of China.
Disputes arising out of these terms should be resolved through friendly negotiation. If negotiation fails, the dispute shall be submitted to the competent people's court at our domicile (Hohhot, Inner Mongolia Autonomous Region).
Note for users outside China: the governing law and jurisdiction provisions above do not exclude rights that you enjoy under mandatory provisions of the law of your country or region and that cannot be excluded by agreement, including your rights as a data subject under the GDPR and your right to lodge a complaint with your local supervisory authority. Where mandatory law in your jurisdiction requires local law to apply, that law applies to the extent it is mandatorily applicable.

Appendix 10. Language versions

Our agreements and policies are available in Simplified Chinese, English, Russian and Mongolian. The Simplified Chinese version prevails. The English, Russian and Mongolian versions are reference translations provided for convenience; in the event of ambiguity, omission or inconsistency between a translation and the Simplified Chinese version, the Simplified Chinese version prevails.

The language-precedence clause is a choice of law matter and takes effect once confirmed by the company; if the company decides on a different arrangement, the wording published on this page as updated will apply.

Appendix 11. Relationship between the documents

Our Privacy Policy, Cookie Policy, Terms of Service, Disclaimer, Acceptable Use Policy, Intellectual Property and Trademark Notice, Children's Privacy Notice, Data Subject Rights and Account Closure Notice, Report and Infringement Complaints page and Accessibility Statement together constitute the entire agreement between you and us regarding your use of the platform. Each document applies to the specific matters it governs. If any document conflicts with this appendix on the identity of the controller, legal bases, processors and third-party disclosures, cross-border transfers, retention periods, data subject rights, security measures, changes and effective date, governing law or language precedence, this appendix prevails; on the specific matters governed by a particular document, that document prevails. If any provision is held invalid or unenforceable, the validity of the remaining provisions is not affected.
