We respect your privacy and are committed to protecting the personal information you provide when using our website (LST | Anti-Drone & Signal Booster Solutions) and services. This Privacy Policy (hereinafter referred to as the “Policy”) complies with applicable laws and regulations (including but not limited to the Personal Information Protection Law of the People’s Republic of China, Cybersecurity Law of the People’s Republic of China, and international privacy standards) and clarifies how we collect, use, store, protect, share, transfer, and disclose your personal information, as well as your rights regarding your personal information.
By accessing or using our website, products, or services, you acknowledge that you have read, understood, and agreed to the entire content of this Policy, and consent to our handling of your personal information in accordance with this Policy. If you do not agree with any provisions of this Policy, please stop using our website and services immediately.
We adhere to the principles of “legitimacy, necessity, and transparency” and only collect personal information that is necessary to provide services, fulfill contracts, or comply with legal obligations. The information we collect falls into the following categories:
When you browse, access, or use our website, our server automatically collects non-identifiable information to optimize website performance and improve user experience. This information does not allow us to identify your personal identity, including but not limited to:
- Technical information: Your device’s IP address, browser type (e.g., Chrome, Safari), operating system (e.g., Windows 11, iOS 17), screen resolution, and network connection type (e.g., Wi-Fi, 5G).
- Usage information: The date and time of your visit, the pages you view (e.g., product pages for anti-drone systems), the duration of your stay, the frequency of visits, and the links you click.
- Traffic statistics: Aggregated data on website visits (e.g., daily active users) to analyze user behavior and optimize server configuration and bandwidth allocation.
We only collect your personal information when you voluntarily provide it for specific purposes (e.g., consulting services, customizing solutions). This information includes but is not limited to:
- Basic identification information: Full name, company name, job title, contact phone number (e.g., +8613126851888), email address (e.g., [email protected]), and communication address (if you need on-site service or product delivery).
- Business-related information: Information about your organization (e.g., industry sector: defense, telecommunications, public safety), specific service needs (e.g., custom anti-drone systems for airports, signal boosters for industrial sites), and requirements for product performance or technical parameters.
- Account-related information (if you register for an account): Account username, password (encrypted storage), and verification information (e.g., SMS verification code for password reset).
We will not collect sensitive personal information (e.g., racial/ethnic origin, religious beliefs, biometric data, health information) unless explicitly authorized by you and required by legal obligations.
In rare cases, we may obtain your personal information from trusted third parties (e.g., industry partners, legal service providers) to confirm your identity or fulfill service commitments. For example:
- If you participate in a joint event co-hosted by LST and a partner, the partner may provide us with your basic contact information (with your prior consent) to facilitate our follow-up on event-related services.
- We may obtain verification information from third-party authentication service providers to confirm the legitimacy of your organization (e.g., business registration information for corporate clients).
We will only use such information for the purposes stated in this Policy and will verify the legality of the third party’s acquisition of your information before using it.
We only use your personal information for the following legitimate purposes, and will not use it for purposes not stated in this Policy without your prior consent:
- Respond to your inquiries: Use your contact information (e.g., phone: +8613126851888, email: [email protected], WhatsApp: +8613126851888) to answer your questions about anti-drone systems, signal jamming modules, or drone boosters, and provide technical support or quotation documents.
- Deliver customized solutions: Based on your business needs (e.g., airport security, industrial site signal enhancement), design and provide tailored RF solutions (e.g., GaN-based high-performance modules) and follow up on project progress.
- Improve service quality: Analyze non-personal information (e.g., page access frequency) to optimize website navigation, update product information, and enhance the usability of our services.
- If you purchase our products or services (e.g., order anti-drone systems), use your contact information and delivery address to arrange product shipment, installation, and after-sales service.
- Comply with applicable laws and regulations: For example, retain transaction records (e.g., order details, payment information) in accordance with tax laws and commercial record-keeping requirements; provide necessary information to government authorities in response to legal inquiries (e.g., requests from law enforcement agencies for public security purposes).
- Verify the identity of users to prevent unauthorized access to your account or misuse of our services (e.g., verifying your phone number via SMS when resetting your account password).
- Detect and prevent fraud, cyberattacks, or other illegal activities (e.g., monitoring abnormal login behavior to protect your account and our system security).
- Inform you of updates to our products, services, or policies (e.g., new launches of anti-drone systems, changes to this Privacy Policy, or service maintenance schedules) via email ([email protected]), SMS, or WhatsApp (+8613126851888).
- Notify you of matters related to contracts or service agreements (e.g., delivery time adjustments for custom signal jamming modules, on-site service appointments).
We take strict measures to ensure the security of your personal information during storage, including:
Unless otherwise required by international laws or cross-border service agreements (e.g., serving clients in Southeast Asia), all your personal information is stored within the territory of the People’s Republic of China (including Hong Kong Special Administrative Region, where our company is based). If cross-border storage of information is necessary (e.g., providing services to overseas clients), we will comply with applicable cross-border data transfer regulations (e.g., filing with relevant authorities, signing data transfer agreements with overseas recipients) and ensure that the recipient implements the same level of security protection measures as required by this Policy.
We only store your personal information for the period necessary to achieve the purposes stated in this Policy, or as required by applicable laws and regulations. The storage period is determined based on the following principles:
- For information related to service provision: Retained for the duration of our service relationship with you, plus 2 years after the service ends (to handle potential after-sales inquiries or disputes).
- For information required by law: Retained for the period specified by laws and regulations (e.g., tax records retained for 7 years in accordance with tax laws; transaction records retained for 5 years in accordance with commercial laws).
After the storage period expires, we will delete your personal information permanently or anonymize it (converting it into non-identifiable data that cannot be restored to personal information) to ensure that it no longer identifies you.
We adopt a combination of technical safeguards and administrative controls to protect your personal information from unauthorized access, use, disclosure, modification, or destruction:
- Technical safeguards: Use encryption technologies (e.g., SSL/TLS for website data transmission, AES-256 for password storage) to protect data in transit and at rest; deploy firewalls, intrusion detection systems (IDS), and anti-virus software to prevent cyberattacks; regularly update system security patches to address potential vulnerabilities.
- Administrative controls: Limit access to personal information to authorized employees only (e.g., sales staff can only access client contact information necessary for their work); conduct regular privacy and security training for employees to ensure they comply with this Policy and legal requirements; sign confidentiality agreements with employees and third-party service providers to prevent information leakage.
We strictly restrict the sharing, transfer, and disclosure of your personal information and will not share or transfer it to any third party (excluding our affiliated companies) without your explicit consent, except in the following circumstances:
We may engage trusted third-party service providers to assist us in providing services (e.g., IT infrastructure maintenance, logistics delivery, email marketing via Hostinger). These third parties only have access to the personal information necessary to perform their services and are required to comply with this Policy and relevant laws, as well as implement security protection measures. Examples include:
- Email service provider (Hostinger) that sends service notifications on our behalf to your email address (e.g., [email protected]);
- Logistics companies that deliver our anti-drone systems or signal modules to you;
- Cloud service providers that store website data (we ensure they comply with data security standards).
We will supervise these third parties to ensure they do not use your personal information for any purposes other than providing services to us, and will terminate cooperation and pursue legal liability if they violate this requirement.
We may disclose your personal information if required by applicable laws, regulations, judicial decisions, or administrative orders (e.g., requests from public security agencies, tax authorities, or industry regulators). In such cases, we will verify the legality of the request and only provide the minimum amount of information necessary to comply with the request, and will not disclose information beyond the scope required by law.
We may disclose your personal information in the following emergency situations to protect your or others’ legitimate rights and interests (e.g., life, property safety) or public interests, without your prior consent:
- To prevent or address immediate risks (e.g., disclosing contact information to emergency services if a product malfunction causes safety hazards);
- To prevent fraud, cyberattacks, or other illegal activities that may harm our website, services, or users;
- To protect public interests (e.g., cooperating with investigations into illegal use of drones that threaten public safety).
We may share, transfer, or disclose aggregated non-personal information (e.g., industry-wide reports on anti-drone technology adoption rates) with third parties (e.g., industry associations, research institutions) for research, market analysis, or public education purposes. This aggregated data does not contain any personal information and cannot be used to identify individuals.
You have the following rights regarding your personal information in accordance with applicable laws and regulations. We will provide convenient channels for you to exercise these rights:
You have the right to access your personal information stored by us (e.g., your contact information, service records). To exercise this right, you may:
- Send an email to [email protected] with the subject line “Request to Access Personal Information”, specifying your full name, registered email/phone number (e.g., +8613126851888), and the information you wish to access;
- Contact us via WhatsApp (+8613126851888) or phone (+8613126851888) during working hours (Monday to Friday, 9:00-18:00 GMT+8).
We will verify your identity (e.g., matching your phone number: +8613126851888 or email address) within 15 working days and provide you with the requested information free of charge (unless the request is excessive or repetitive, in which case we may charge a reasonable fee as permitted by law).
If you find that your personal information stored by us is inaccurate or incomplete (e.g., incorrect company name, outdated phone number: +8613126851888), you have the right to request corrections or supplements. To exercise this right:
- Follow the same contact method as in Section 6.1, specifying the information that needs correction and providing supporting documents (if necessary, e.g., a company business license for correcting company information);
- If you have registered an account, you may correct basic information (e.g., email address) directly through the “Account Settings” page of our website.
We will review and complete the correction or supplement within 10 working days after verifying your identity.
You have the right to request us to delete your personal information in the following circumstances:
- We no longer need your personal information to provide services (e.g., the service relationship has ended and the storage period has expired);
- You withdraw your consent to our use of your personal information (and there is no other legal basis for us to continue using it);
- Our collection or use of your personal information violates this Policy or applicable laws.
To exercise this right, contact us via the methods in Section 6.1. We will delete your personal information within 15 working days after verification, or anonymize it if complete deletion is technically impossible.
You may withdraw your consent to our collection, use, or sharing of your personal information at any time (except where consent is not required by law). For example:
- If you no longer wish to receive our product updates or industry insights via email, you can click the “Unsubscribe” link at the bottom of the email (sent to [email protected]);
- If you withdraw consent for us to use your contact information (e.g., +8613126851888, +8613126851888) for solution customization, please notify us via email or phone.
Withdrawing consent will not affect the legality of our handling of your personal information before you withdrew consent (e.g., we may still retain transaction records to comply with tax laws). If you withdraw consent for necessary services (e.g., providing your contact information for technical support), we may no longer be able to provide the corresponding services to you.
If you believe that our handling of your personal information violates this Policy or applicable laws, or if you have disputes regarding the protection of your personal information, you may:
- Contact our customer service team first: Email [email protected] or call +8613126851888. We will investigate and respond to you within 30 working days;
- Lodge a complaint with the relevant regulatory authority: For example, the Cyberspace Administration of China, the local Bureau of Market Regulation, or the privacy protection authority in your jurisdiction.
Our website may contain links to third-party websites, products, or services (e.g., links to industry news platforms, partner company websites). These third parties have their own privacy policies and terms of service, and we have no control over their collection, use, or protection of your personal information.
We are not responsible for the content of third-party websites or services, or for their compliance with privacy laws. We recommend that you carefully read the privacy policies and terms of service of any third-party websites or services before accessing or using them, and exercise caution when providing your personal information to third parties.

We will not intentionally collect personal information from minors.
If a minor provides personal information to us without the consent of their legal guardian, the legal guardian may contact us via
[email protected] to request the deletion of such information. We will verify the guardian’s identity and delete the minor’s personal information immediately after confirmation.
