Please read these terms before ordering or subscribing. Separate terms shown at checkout, in an app store, on an invoice or in a signed OEM / ODM agreement also apply. If they conflict, the more specific transaction terms control for that transaction.
1. Who we are
This website and the KINGSTARFit connected-service offering are operated by KINGSTAR INTERNATIONAL ENTERPRISE LIMITED (金斯達實業有限公司), A private company limited by shares incorporated in Hong Kong, Business Registration No. 66909991. “KINGSTAR FIT”, “we”, “us” and “our” refer to that entity unless another seller is identified at checkout or in a written agreement. For direct website payments processed through Stripe, this Hong Kong company is the merchant, contracting seller and payment recipient; Stripe is the payment processor.
2. Acceptance and eligibility
By accessing the website, creating an account, placing an order or starting a subscription, you agree to these terms and the policies linked from our Legal Center. You must have legal capacity to enter a contract. Purchases and subscriptions by minors must be made and supervised by a parent or legal guardian.
3. Accounts and device access
You must provide accurate account information, protect login credentials and notify us promptly of suspected unauthorized access. You are responsible for activity performed through your account unless applicable law provides otherwise. Device compatibility, phone permissions, network access and supported operating-system versions may affect individual features.
4. Products and wellness information
We aim to describe products accurately. Images, colours, measurements, battery performance and available functions can vary by production batch, phone, firmware, settings, network and region. Packaging and localized features may differ from examples shown.
KINGSTAR FIT wearables and App outputs are intended for general wellness and lifestyle reference. They are not medical devices unless a particular product is expressly documented and lawfully marketed as one in the relevant country. They do not diagnose, treat or prevent disease and must not be used for emergencies. Seek qualified medical advice about health concerns and call local emergency services when necessary.
5. Orders and contract formation
An order submission is an offer to buy. An automated acknowledgement confirms receipt, not acceptance. A contract is formed when we send an order confirmation, activate a paid service or dispatch the goods, as applicable. We may reject or cancel an order for stock errors, pricing errors, suspected fraud, sanctions or export restrictions, unsupported destinations or inability to supply. If payment has been captured for a rejected order, we will refund it.
6. Prices, taxes and payment
The checkout or order confirmation identifies the price, currency, billing frequency, applicable tax and delivery charge. Customs duties and import taxes may be payable by the recipient where stated. Payments may be processed by Stripe, an app store or another provider identified at checkout. Those providers process payment credentials under their own terms and privacy notices. A direct Stripe checkout does not change the identity of the seller: unless the checkout states otherwise, the seller and payment recipient is KINGSTAR INTERNATIONAL ENTERPRISE LIMITED.
You authorize the displayed charge and confirm that you may use the selected payment method. Recurring charges are subject to our Subscription & Cancellation Policy.
7. Shipping, returns and warranty
Physical orders are governed by our Shipping & Delivery Policy, Returns & Refunds Policy and Limited Warranty. Do not send products to our registered office without return authorization.
8. Subscriptions and digital services
Paid plans provide the features, duration and usage limits displayed before purchase. Subscriptions normally renew automatically until cancelled through the original billing channel. Core pairing and basic device controls remain available for supported devices without Premium, subject to reasonable service maintenance and compatibility requirements.
9. B2B, wholesale and OEM / ODM orders
A B2B quotation identifies the contracting seller, buyer, products or services, quantity, currency, quotation-validity period, applicable taxes, payment schedule, production scope, estimated lead time and delivery basis. No B2B order is accepted until the quotation, purchase order or written agreement is accepted by the identified seller and any required deposit or advance payment has cleared.
Unless the quotation states otherwise, production timing starts only after cleared deposit, final specification, artwork, sample and packaging approval. Lead times are estimates and may be revised for approved changes, component availability, compliance work or events outside reasonable control. The balance must be paid at the stage stated in the quotation and before dispatch where required. Each party bears bank charges, taxes and duties allocated to it by the quotation or applicable law.
Delivery, risk, title, freight, insurance, export documents and import responsibility follow the Incoterm and named place stated in the quotation or agreement. Customized, private-label and made-to-order goods cannot be cancelled or returned after production commitment except as expressly agreed or required by law. Inspection, defect, warranty and claims periods for B2B orders are those stated in the applicable commercial documents.
10. Acceptable use
You must not:
- use the website, App or device services unlawfully, fraudulently or to harm another person;
- attempt unauthorized access, interfere with security, introduce malicious code or overload a service;
- reverse engineer, scrape or copy protected software except where applicable law expressly permits it;
- upload content that infringes rights, contains malware or is deceptive, abusive or unlawful; or
- resell a personal subscription, bypass plan limits or use another person’s account without authority.
We may restrict or suspend access where reasonably necessary to protect users, systems, legal compliance or payment integrity. Where practicable, we will provide notice and an opportunity to resolve the issue.
11. Intellectual property
The website, App, firmware, designs, text, graphics, trademarks and other materials are owned by us or our licensors. We grant a limited, revocable, non-exclusive, non-transferable right to use the service for its intended personal or authorized business purpose. No ownership rights are transferred.
12. Third-party services
App stores, payment providers, maps, AI providers, carriers and linked websites operate under their own terms. We are not responsible for an independent third party’s service, but this does not exclude responsibility that cannot lawfully be excluded.
13. Service changes and availability
We may update features, firmware, security measures and interfaces. Services may be interrupted for maintenance, network failures, safety issues or events outside reasonable control. If we discontinue a material prepaid feature, we will provide an appropriate remedy required by the transaction terms and applicable law.
14. Liability
Nothing in these terms excludes liability that cannot be excluded under applicable law. To the extent permitted by law, we are not liable for indirect or consequential loss, lost profits or loss caused by misuse, unsupported modifications, third-party networks or reliance on general wellness reference data. For a paid consumer transaction, our aggregate liability relating to that transaction will not exceed the amount paid for the affected product or service, unless applicable law requires otherwise.
15. Governing law and disputes
These terms are governed by the laws of the Hong Kong Special Administrative Region, without limiting mandatory consumer rights available in your country of residence. Please contact us first so we can try to resolve a concern. Subject to any mandatory forum rights, the courts of Hong Kong have non-exclusive jurisdiction.
16. Changes and severability
We may update these terms for future use. Material changes affecting an active paid service will be notified reasonably in advance where required. If a provision is unenforceable, the remaining provisions continue to apply. A failure to enforce a provision is not a waiver.
17. Contact
Questions or complaints may be sent to support@ikingstarfit.com. Billing questions may be sent to billing@ikingstarfit.com, or correspondence may be posted to Unit B, 13/F, Shing Lee Commercial Building, No. 8 Wing Kut Street, Central, Hong Kong.
