  1. Introduction

Welcome to SHJ Communications. These Terms and Conditions govern your access to and use of https://tiengu.com, including the purchase of physical products, software, downloadable materials, and other products or services offered through this website.

This website is operated by Nan’an Tingfengzhe Communication Equipment Co., Ltd. (南安听风者通讯设备有限公司), trading as SHJ Communications.

By accessing this website, creating an account, placing an order, or downloading any materials, you agree to these Terms and Conditions. If you do not agree, please do not use this website.

  1. Eligibility

By using this website, you confirm that you are legally capable of entering into a binding agreement under the laws applicable to you.

If you are using this website on behalf of a company or organization, you confirm that you have authority to bind that organization to these Terms and Conditions.

  1. Products and Information

We make reasonable efforts to ensure that product descriptions, specifications, photographs, software information, availability, and prices are accurate.

However, colors, appearance, packaging, technical specifications, and other product details may differ slightly from the information displayed on the website. We may correct errors, update information, or modify products without prior notice.

Customers are responsible for confirming that a product, software package, or downloadable file is compatible with their intended equipment, system, frequency range, operating environment, and local regulatory requirements before purchasing or using it.

  1. Orders and Acceptance

Submitting an order does not automatically mean that we have accepted it.

We reserve the right to accept, reject, limit, or cancel an order for reasons including:

• Product unavailability
• Incorrect pricing or product information
• Suspected fraud or unauthorized payment
• Shipping restrictions
• Export, import, sanctions, or regulatory restrictions
• An incorrect or incomplete delivery address

A binding sales agreement is formed when we confirm acceptance of the order or begin processing or shipping the order.

If we cancel a paid order, we will refund the applicable amount using the original payment method whenever reasonably possible.

  1. Prices, Currency, Taxes, and Payment

Unless otherwise stated, prices on this website are displayed in United States dollars (USD).

Customers are responsible for any applicable taxes, VAT, GST, customs duties, import charges, bank charges, currency conversion fees, or other government charges imposed in the destination country or region, unless the checkout page expressly states that such charges are included.

Payment must be completed using one of the payment methods available during checkout. Orders may be held or cancelled if payment cannot be verified.

We reserve the right to correct pricing errors before accepting an order. If an error affects an order already submitted, we will contact the customer to confirm the corrected price or cancel and refund the order.

  1. Shipping and Delivery

Shipping destinations, methods, estimated delivery times, and charges are displayed on the website or during checkout where available.

Delivery times are estimates and are not guaranteed. Delays may occur because of customs processing, carriers, weather, holidays, incorrect addresses, supply interruptions, or events outside our reasonable control.

Customers must provide a complete and accurate delivery address. Additional costs resulting from an incorrect address, refused delivery, unsuccessful delivery, or failure to complete customs procedures may be charged to the customer where permitted by law.

Additional information is provided in our Shipping Policy.

  1. International Orders

Customers placing international orders are responsible for ensuring that the purchased products may legally be imported, possessed, installed, and used in the destination country or region.

Some communication equipment, radio products, electronic products, software, encryption technology, or related technical materials may be subject to licensing, certification, frequency, import, export, or end-use restrictions.

The customer is responsible for obtaining any required permits, approvals, certifications, or licenses. We may refuse or cancel an order when fulfilling it could violate applicable trade, export, sanctions, or other legal requirements.

  1. Returns, Cancellations, and Refunds

Returns, order cancellations, replacements, and refunds are governed by our Return and Refund Policy.

Customers should inspect physical products promptly after delivery and contact us within the period stated in that policy if an item is damaged, defective, incorrect, or missing.

Nothing in these Terms limits any non-waivable consumer rights provided by applicable law.

  1. Software and Downloadable Materials

Software, firmware, manuals, documentation, and other downloadable materials are licensed, not sold, unless expressly stated otherwise.

Subject to these Terms and any product-specific license, we grant the customer a limited, non-exclusive, non-transferable, and revocable right to download and use the materials for their intended lawful purpose.

Customers may not:

• Copy, resell, sublicense, distribute, publish, or commercially exploit downloadable materials without written permission
• Remove copyright, trademark, ownership, or license notices
• Reverse engineer, decompile, or attempt to extract source code except where applicable law expressly permits it
• Use the materials to violate laws, interfere with networks, or gain unauthorized access to systems
• Share paid download links, license keys, or account credentials with unauthorized persons

Download access may be limited by time, number of downloads, account status, or product-specific conditions displayed at the time of purchase.

Because digital content may be supplied immediately, cancellation or refund rights may be affected after downloading or accessing the content, where permitted by applicable law. Any mandatory consumer rights remain unaffected.

  1. Accounts and Security

Customers are responsible for providing accurate account information and keeping login credentials confidential.

You are responsible for activities conducted through your account unless caused by our failure to use reasonable security measures. Please notify us promptly if you believe your account or credentials have been compromised.

We may suspend or terminate accounts that are used fraudulently, unlawfully, abusively, or in violation of these Terms.

  1. Intellectual Property

The website and its content—including text, graphics, logos, product photographs, software, documentation, downloads, page designs, and trademarks—are owned by or licensed to SHJ Communications and are protected by applicable intellectual property laws.

You may use website content only for personal or internal business evaluation and purchasing purposes. No ownership rights are transferred to you.

You may not reproduce, republish, modify, distribute, sell, scrape, or commercially exploit website content without our prior written permission.

  1. Product Use and Safety

Customers must follow all product instructions, technical documentation, safety notices, installation requirements, and applicable laws.

Unless expressly stated otherwise, our products must not be used in life-support systems, emergency systems, aviation control, nuclear facilities, military applications, or other high-risk environments where failure could result in death, personal injury, or severe property or environmental damage.

The customer is responsible for appropriate installation, configuration, testing, maintenance, and lawful operation of purchased products.

  1. Disclaimer of Warranties

To the maximum extent permitted by law, this website and its content are provided on an “as available” basis.

We do not guarantee that the website will always be uninterrupted, error-free, secure, or compatible with every device or system.

Product warranties, if any, are limited to the warranty terms supplied with the product or displayed on the relevant product page. Nothing in this section excludes warranties or consumer protections that cannot legally be excluded.

  1. Limitation of Liability

To the maximum extent permitted by applicable law, SHJ Communications and Nan’an Tingfengzhe Communication Equipment Co., Ltd. will not be liable for indirect, incidental, special, punitive, or consequential losses, including loss of profits, revenue, data, business, or opportunity.

Where liability cannot be excluded, our total liability arising from a particular order will generally not exceed the amount paid for the product giving rise to the claim, except where a different limitation is required by applicable law.

Nothing in these Terms excludes or limits liability that cannot legally be excluded or limited, including liability for fraud or personal injury caused by negligence where applicable.

  1. Third-Party Services and Links

This website may use or link to third-party payment providers, shipping companies, analytics services, social media platforms, websites, software, or other services.

Third-party services are governed by their own terms and privacy policies. We are not responsible for third-party websites or services that we do not control.

  1. Privacy

Our collection and use of personal information are described in our Privacy Policy. By using this website, you acknowledge that you have reviewed that policy.

  1. Force Majeure

We are not responsible for delays or failure to perform caused by circumstances outside our reasonable control, including natural disasters, epidemics, war, government actions, sanctions, strikes, transportation interruptions, customs delays, power failures, telecommunications failures, or supply-chain disruptions.

  1. Changes to These Terms

We may update these Terms and Conditions when our products, services, operations, or legal obligations change.

The revised version will be published on this page with an updated “Last Updated” date. Changes will apply from the date of publication and will not retroactively alter completed orders unless required by law.

  1. Governing Law and Disputes

These Terms are governed by the laws of the People’s Republic of China, without regard to conflict-of-law principles.

Any dispute should first be addressed by contacting us so that we can attempt to resolve it in good faith.

If a dispute cannot be resolved, it may be submitted to a court with lawful jurisdiction in the location where Nan’an Tingfengzhe Communication Equipment Co., Ltd. is registered, unless mandatory consumer-protection laws give the customer the right to bring a claim in another jurisdiction.

  1. Severability

If any provision of these Terms is found to be invalid or unenforceable, the remaining provisions will continue in effect.
