These Terms of Service (the "Terms") form a legally binding agreement between you and HK TRENRIX CO., LIMITED ("we", "us", or "our") governing your use of our website at xinhengtonghk.com, our mobile applications published on the Apple App Store and Google Play, and any related services, content, features, or functionality we offer (together, the "Services"). By accessing or using the Services, you confirm that you have read, understood, and agreed to be bound by these Terms. If you do not agree, please do not use the Services.

01 Acceptance of Terms

By creating an account, installing one of our applications, visiting our website, or otherwise accessing or using the Services, you accept these Terms and our Privacy Policy, which is incorporated into these Terms by reference. If you are accepting these Terms on behalf of a company or other legal entity, you represent that you have the authority to bind that entity, in which case "you" refers to that entity. If you do not have such authority, or if you do not agree with these Terms, you must not accept or use the Services.

We may also require you to accept supplemental terms that apply to specific features, products, or services (for example, beta programmes, sweepstakes, or region-specific disclosures). Any such supplemental terms will be presented when you access the relevant feature and will form part of these Terms.

02 Eligibility & Account Registration

You must be at least the age of digital consent in your country of residence to use the Services. In most jurisdictions this is 13 years (COPPA, USA); in EEA / UK member states it is typically 16 unless a Member State sets it lower (with parental consent); in other regions we apply the higher of any locally required age.

To access certain features you may be asked to create an account. When you do, you agree to:

  • provide accurate, current, and complete information;
  • keep your account information updated;
  • maintain the security of your account credentials and any device used to access the Services;
  • promptly notify us if you discover or suspect any unauthorized access to your account;
  • accept responsibility for all activities that occur under your account, whether or not you authorized them.

We may refuse registration, suspend, or terminate accounts that we reasonably believe violate these Terms or pose a risk to other users, us, or third parties. You may close your account at any time by emailing support@xinhengtonghk.com.

03 License to Use Our Services

Subject to your continued compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to:

  • access and use our website for personal, non-commercial information and engagement purposes;
  • download, install, and use our mobile applications on devices you own or control, for personal, non-commercial use (or for use within your business, where applicable).

For our mobile applications, the license is also subject to your compliance with the Apple EULA or Google Play Terms of Service (as applicable) and any usage rules set by the applicable app store. The license is conditioned on your compliance with these Terms and is automatically revoked if you breach any provision of these Terms.

All rights not expressly granted to you are reserved by HK TRENRIX or its licensors. You may not resell, redistribute, sublicense, or commercially exploit the Services except as expressly permitted by us in writing.

04 Acceptable Use & Code of Conduct

You agree to use the Services only for lawful purposes and in a way that does not infringe the rights of, restrict, or inhibit anyone else's use and enjoyment of the Services. In particular, you agree NOT to:

  • violate any applicable law, regulation, or contractual obligation;
  • post, upload, or transmit any content that is unlawful, harmful, threatening, abusive, harassing, defamatory, vulgar, obscene, hateful, or racially, ethnically, or otherwise objectionable;
  • impersonate any person or entity, or falsely state or otherwise misrepresent your affiliation with a person or entity;
  • engage in any activity that interferes with or disrupts the Services or the servers or networks connected to the Services;
  • attempt to gain unauthorized access to any portion of the Services, other accounts, computer systems, or networks connected to the Services;
  • use any robot, spider, scraper, or other automated means to access the Services or extract data, except as permitted by our robots.txt or with our prior written consent;

  • upload or distribute viruses, malware, ransomware, or other harmful code;
  • use the Services to send unsolicited communications, promotions, advertisements, or spam;
  • circumvent, disable, or otherwise interfere with security-related features of the Services or features that enforce limitations on use.

We may investigate and take appropriate legal action against anyone who, in our sole discretion, violates this section, including reporting such conduct to law-enforcement authorities.

05 Intellectual Property Rights

Our marks and content

The Services and all content, features, and functionality thereon — including but not limited to text, graphics, logos, icons, images, audio clips, video clips, data compilations, software, and the design, selection, and arrangement thereof — are owned by HK TRENRIX, our licensors, or other providers of such material and are protected by international copyright, trademark, patent, trade-secret, and other intellectual property or proprietary rights laws.

"HK TRENRIX", the HK TRENRIX logo, our mascot illustrations, and any other product or service names or slogans displayed on the Services are trademarks of HK TRENRIX or our licensors. You may not use such marks without our prior written permission. All other trademarks not owned by us that appear on the Services are the property of their respective owners.

Your content

If you submit, upload, post, or otherwise make available any text, images, audio, video, or other material through the Services ("Your Content"), you retain any ownership rights you already hold in that content. You grant us a worldwide, non-exclusive, royalty-free, transferable, sublicensable license to use, reproduce, distribute, display, perform, and modify Your Content in connection with operating, developing, and improving the Services. See Section 6 for more detail.

06 User-Generated Content

The Services may allow you to submit reviews, comments, feedback, suggestions, support tickets, or other content. You are solely responsible for Your Content and the consequences of posting or publishing it.

By submitting Your Content, you represent and warrant that: (i) you own or have the necessary rights and permissions to submit it; (ii) Your Content does not and will not infringe or misappropriate the intellectual-property rights, privacy rights, or publicity rights of any third party; (iii) Your Content is not unlawful, defamatory, obscene, or otherwise objectionable; and (iv) you have obtained any required consent from any identifiable individual whose personal data or likeness appears in Your Content.

We do not pre-screen all user-generated content and we make no representation or warranty as to its accuracy, quality, or legality. We may, but are not obligated to, monitor, edit, or remove Your Content at any time and for any reason, including content we consider to violate these Terms. We may also suspend or ban repeat infringers in accordance with our Copyright Policy (available on request).

07 Third-Party Services & Links

Apple App Store and Google Play

Our mobile applications are distributed through the Apple App Store and Google Play. By downloading our apps you also agree to be bound by the Apple EULA, the Apple Media Services Terms, and (separately) the Google Play Terms of Service. Apple and Google are third-party beneficiaries of these Terms and may enforce them against you in respect of your use of their respective platforms and stores.

Advertising partners

Our apps integrate third-party ad mediation networks and advertising SDKs (AdMob, AppLovin, Meta Audience Network, Unity Ads, ironSource, Vungle, InMobi, Pangle, Mintegral, Chartboost, AdColony, Tapjoy, and others). These partners act as independent controllers of the data they collect and are governed by their own terms and privacy policies. The full list of partners, with links to their terms and opt-out pages, is maintained in our Privacy Policy and the internal compliance matrix at docs/ad-platforms.md.

We configure consent management (Apple's App Tracking Transparency framework, Google's User Messaging Platform, and our own consent banner) to honour user choices before serving personalised ads. Open-screen, rewarded video, interstitial, and banner ad formats are described in our Privacy Policy.

Social platforms and other third-party services

The Services may contain links to third-party websites, social-media pages, plug-ins, or services that we do not own or control. Clicking those links is at your own risk, and we encourage you to read the terms and privacy policies of each third-party service you visit. We have no control over, and assume no responsibility for, the content, terms, or privacy practices of any third-party service.

08 Subscriptions, Purchases & Billing

Some of our Services may be offered on a paid basis (for example, premium in-app subscriptions, ad removal, or virtual goods). Where this applies, additional terms will be presented at the point of purchase and will form part of these Terms.

Billing and renewals

Paid subscriptions are billed in advance on a recurring basis (monthly, annually, or another interval disclosed at purchase). Your payment method will be charged automatically at the start of each billing period unless you cancel before the renewal date. Prices are stated in the currency shown at purchase and may exclude applicable taxes, which are added at checkout where required.

Cancellations and refunds

You may cancel a subscription at any time through the applicable app store's subscription settings (Apple Subscriptions on iOS, Google Play Subscriptions on Android) or through the controls we provide. Cancellations take effect at the end of the current billing period; you will retain access to paid features until then. Except where required by law (for example, the EU Consumer Rights Directive's 14-day withdrawal right, where applicable), paid fees are non-refundable. If you believe a charge was made in error, please contact us at support@xinhengtonghk.com within 30 days and we will investigate.

Virtual goods

Virtual currencies, items, or other in-app goods are licensed, not sold, and have no real-world monetary value. They cannot be exchanged for cash or transferred outside the application, except as required by applicable law.

09 Disclaimers & No Warranties

THE SERVICES ARE PROVIDED ON AN "AS IS" AND "AS AVAILABLE" BASIS, WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND. WITHOUT LIMITING THE FOREGOING, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, HK TRENRIX DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT, AS WELL AS ANY WARRANTIES THAT THE SERVICES WILL BE UNINTERRUPTED, ERROR-FREE, SECURE, OR FREE OF HARMFUL COMPONENTS, OR THAT ANY DEFECTS WILL BE CORRECTED.

We do not warrant the accuracy, completeness, or usefulness of any content made available through the Services, including third-party advertising content. Any reliance you place on such content is at your own risk. We make no representations or warranties regarding the conduct of any user or third party.

Some jurisdictions do not permit the exclusion of certain warranties; in those jurisdictions the exclusions above apply to the maximum extent permitted by law, and any non-excludable warranties are limited to the minimum duration permitted by law.

10 Limitation of Liability

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL HK TRENRIX, ITS DIRECTORS, OFFICERS, EMPLOYEES, AGENTS, PARTNERS, SUPPLIERS, OR LICENSORS BE LIABLE FOR ANY: (i) INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, INCLUDING LOSS OF PROFITS, REVENUE, DATA, USE, GOODWILL, OR OTHER INTANGIBLE LOSSES; (ii) DAMAGES RESULTING FROM (A) YOUR ACCESS TO OR USE OF (OR INABILITY TO ACCESS OR USE) THE SERVICES, (B) ANY CONDUCT OR CONTENT OF ANY THIRD PARTY ON OR THROUGH THE SERVICES, (C) ANY CONTENT OBTAINED FROM THE SERVICES, OR (D) UNAUTHORIZED ACCESS, USE, OR ALTERATION OF YOUR TRANSMISSIONS OR CONTENT; WHETHER BASED ON WARRANTY, CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, STATUTE, OR ANY OTHER LEGAL THEORY, WHETHER OR NOT WE HAVE BEEN INFORMED OF THE POSSIBILITY OF SUCH DAMAGE.

IN NO EVENT WILL OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS RELATING TO THE SERVICES EXCEED THE GREATER OF (A) ONE HUNDRED U.S. DOLLARS (US$100) OR (B) THE AMOUNTS YOU HAVE PAID TO US (IF ANY) IN THE TWELVE (12) MONTHS IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO THE CLAIM.

EU / UK consumers

Nothing in these Terms is intended to exclude or limit liability that cannot be excluded or limited under the law of your country of residence, including liability for death or personal injury caused by our negligence, liability for fraud or fraudulent misrepresentation, or statutory rights you have as a consumer under the EU Consumer Rights Directive, the UK Consumer Rights Act 2015, or equivalent local law.

U.S. consumers

Nothing in these Terms is intended to exclude or limit liability that cannot be excluded or limited under applicable U.S. federal or state law, including liability for death or personal injury caused by our negligence, liability for fraud, or implied warranties that cannot be disclaimed under the Magnuson-Moss Warranty Act. Residents of New Jersey (and other states with equivalent laws) retain all rights they would otherwise have under those states' laws.

11 Indemnification

You agree to defend, indemnify, and hold harmless HK TRENRIX and its directors, officers, employees, agents, partners, suppliers, and licensors from and against any and all claims, damages, obligations, losses, liabilities, costs, or expenses (including reasonable attorneys' fees) arising from:

  • your access to or use of the Services;
  • Your Content;
  • your violation of these Terms;
  • your violation of any third-party right, including any intellectual-property, privacy, or publicity right;
  • any claim that your use of the Services has caused damage to a third party.

This indemnification obligation will survive termination of these Terms and your use of the Services.

12 Termination

Termination by you

You may stop using the Services at any time. You may also close your account (where applicable) by emailing support@xinhengtonghk.com. For paid subscriptions, cancellation takes effect at the end of the current billing period — see Section 8.

Termination by us

We may suspend or terminate your access to all or part of the Services at any time, with or without notice, if:

  • you breach these Terms or our Privacy Policy;
  • your use of the Services creates a security risk or disrupts our operations;
  • we are required to do so by law, regulation, court order, or a regulator;
  • we discontinue the Services (in which case we will give reasonable advance notice where practicable).

Effect of termination

Upon termination: (a) your license to use the Services ends; (b) we may delete your account data in line with our retention policy (see our Privacy Policy); (c) provisions that by their nature should survive — including Intellectual Property, Disclaimers, Limitation of Liability, Indemnification, Governing Law, and Contact — will survive. Termination does not extinguish any obligation that has already accrued.

13 Governing Law & Dispute Resolution

Governing law

These Terms, and any non-contractual obligations arising out of or in connection with them, are governed by and construed in accordance with the laws of the Hong Kong Special Administrative Region of the People's Republic of China, save where mandatory consumer-protection laws of your country of residence apply (in which case those mandatory laws will prevail to the extent of any conflict).

Venue and jurisdiction

The courts of Hong Kong have exclusive jurisdiction to settle any dispute or claim (including non-contractual disputes or claims) arising out of or in connection with these Terms or their subject matter, save that we may bring enforcement proceedings in any court of competent jurisdiction in respect of any breach of our intellectual-property rights, and save where mandatory consumer-protection laws give you the right to bring proceedings in your country of residence.

Informal resolution first

We want to resolve disputes before they escalate. Before filing a claim, please email support@xinhengtonghk.com with a description of the dispute and how we can resolve it. We will attempt to resolve the dispute by contacting you via email within thirty (30) days. Nothing in this paragraph prevents either party from seeking interim or injunctive relief in a court of competent jurisdiction.

EU / UK consumer-rights carve-out

If you are a consumer residing in the European Economic Area or the United Kingdom, you may also bring legal proceedings in the courts of your country of residence, and the mandatory consumer-protection laws of your country apply to you regardless of the choice of governing law above. In addition, the European Commission's Online Dispute Resolution platform is available at https://ec.europa.eu/consumers/odr for consumers who wish to resolve a dispute out of court.

U.S. consumer-rights carve-out

If you are a U.S. consumer, nothing in this section limits any right you have under the law of your state of residence to bring an action in your local courts, including claims under state consumer-protection statutes, the Magnuson-Moss Warranty Act, or other applicable federal law.

14 Changes to Terms

We may update these Terms from time to time. When we do, we will revise the "Last updated" date at the top of these Terms. For material changes, we will give reasonable advance notice through our website, our apps, or (where you have provided one and have not unsubscribed) by email. Material changes will not apply retroactively, and the effective date of any new terms will be stated at the top of the document.

Your continued use of the Services after the effective date of any updated Terms constitutes your acceptance of the changes. If you do not agree to the updated Terms, you must stop using the Services and (where applicable) close your account. A version history of these Terms is maintained at https://xinhengtonghk.com/terms.html#version-history and includes a summary of material changes for each version.

15 Contact

If you have any questions about these Terms, please contact us at:

We will respond to your message as soon as reasonably practicable, and in any event within the timeframes required by applicable law.

For the avoidance of doubt, these Terms apply to the website xinhengtonghk.com and to all mobile applications published by HK TRENRIX CO., LIMITED on the Apple App Store and Google Play, together with any successor domains or applications we may operate. Where any term conflicts with a mandatory consumer-protection law in your jurisdiction, that mandatory law prevails.
