Terms of Service

Last updated: July 29, 2026

1. Overview and Acceptance of These Terms

Welcome to Kraftsense. These Terms of Service govern your access to and use of kraftsensetool.com, including the website, online store, customer accounts, content, tools, products, and related services collectively referred to as the “Services.”

The terms “Kraftsense,” “we,” “us,” and “our” refer to:

Kunheng HongKong Limited
92 Granville Road
Kowloon
Hong Kong SAR

Business Registration Number: 78676639
Customer Support: support@kraftsensetool.com

Kraftsense is the trading name used for the online store.

By accessing or using the Services, creating an account, or placing an order, you agree to these Terms and acknowledge our Privacy Policy, Return and Refund Policy, Shipping Policy, and any other policies made available through the website.

If you do not agree to these Terms, you should not use the Services.

Nothing in these Terms limits any rights that cannot legally be waived under applicable federal, state, or local law.

2. Eligibility and Customer Accounts

You must be at least 18 years old or the age of legal majority in your place of residence to place an order or create an account.

When using the Services, you agree to provide accurate, current, and complete information, including your contact, billing, payment, and shipping information.

You are responsible for:

• keeping your account credentials confidential;

• restricting unauthorized access to your account;

• promptly updating inaccurate or outdated information; and

• notifying us if you suspect unauthorized use of your account.

You may not sell, transfer, assign, rent, or license your account to another person.

We may suspend or restrict an account when reasonably necessary to address suspected fraud, unlawful activity, security risks, misuse of the Services, or a material violation of these Terms.

Suspension or termination of an account does not affect previously accepted orders, payment obligations, or rights that arose before the suspension or termination.

3. Product Information

We make reasonable efforts to accurately describe and display our products, including their specifications, dimensions, included components, compatibility, features, and intended uses.

Product colors and appearance may vary slightly depending on screen settings, lighting, photography, manufacturing tolerances, or other technical factors.

Minor display differences do not affect your rights if the product is materially different from its description, defective, damaged, incomplete, or unsuitable under applicable law.

Before placing an order, you should review:

• the product description;

• the included accessories and components;

• battery and charger compatibility;

• voltage and electrical requirements;

• size, weight, and dimensions;

• operating and safety instructions; and

• any geographic or use restrictions.

We may update product descriptions, discontinue products, or change future product availability. Changes will not retroactively alter an order that we have already accepted.

Product availability may be limited by inventory, location, legal requirements, safety restrictions, or shipping limitations.

4. Orders and Contract Formation

Products displayed on the website are invitations to place an order and do not constitute a binding offer by Kraftsense.

By submitting an order, you make an offer to purchase the products listed in your order.

After submission, we may send an automated order acknowledgment. An automated acknowledgment confirms receipt of your order but does not necessarily mean that we have accepted it.

Unless expressly stated otherwise, an order is accepted when we:

• send an express order acceptance;

• send a shipping confirmation; or

• ship the ordered product,

whichever occurs first.

Payment authorization or a temporary payment hold does not by itself mean that the order has been accepted.

We may decline an order before acceptance for a legitimate reason, including:

• lack of inventory;

• payment failure or lack of authorization;

• an obvious pricing, product, or technical error;

• suspected fraud, resale, abuse, or unlawful activity;

• an invalid or undeliverable address;

• legal, regulatory, safety, or shipping restrictions; or

• quantities that materially exceed normal personal or household use.

If we decline an order after receiving payment, we will issue a refund to the original payment method.

Customers should review all order details before submitting an order. Cancellation requests are not guaranteed after an order has entered processing or has shipped.

If an order has already shipped, the customer may request a return under our Return and Refund Policy.

5. Prices, Taxes, and Fees

Prices may change at any time before an order is placed.

The price charged will be the price displayed at checkout when the order is submitted, subject to correction of obvious errors before order acceptance.

Applicable sales tax, shipping charges, and other required charges will be displayed before you complete the purchase.

Unless clearly disclosed before purchase, we will not add undisclosed mandatory charges after the order is submitted.

Promotions, coupons, discounts, bundles, and limited-time offers may be subject to additional terms. If promotional terms conflict with these Terms, the specific promotional terms apply to that promotion.

Promotions may not be combined unless expressly permitted.

For international orders, any applicable duties, import taxes, brokerage costs, or customs charges will be disclosed where reasonably possible or governed by the shipping terms presented before purchase.

6. Payment

Available payment methods are displayed during checkout.

You represent that:

• the payment information you provide is accurate;

• you are authorized to use the selected payment method; and

• the payment provider may charge the amount shown at checkout.

We may use third-party payment processors. Their terms and privacy practices may apply to the payment services they provide.

We may delay shipment until payment has been successfully authorized or received.

If a payment is reversed, rejected, disputed, or subject to a chargeback, we may suspend fulfillment while the matter is reviewed.

Nothing in this section limits a customer’s lawful right to dispute an unauthorized or incorrect charge.

7. Shipping and Delivery

Available shipping methods, estimated delivery times, and applicable shipping charges will be displayed on the website or during checkout.

Delivery dates are estimates unless we expressly guarantee a specific date.

We will make reasonable efforts to ship within the time stated at checkout or in the order confirmation.

If we cannot ship within the stated period, we may contact you to:

• provide a revised shipping date;

• request consent to the delay;

• offer an alternative product where appropriate; or

• cancel the affected item and issue a refund.

If we cannot fulfill the order and no acceptable alternative is agreed, we will refund the amount paid for the unshipped product, including associated charges that must be refunded under applicable law.

We are not responsible for delays caused by events outside our reasonable control, such as severe weather, carrier interruptions, natural disasters, labor disputes, governmental actions, customs delays, or transportation emergencies.

However, events outside our control do not eliminate any refund, cancellation, or other rights that apply under law.

8. Risk of Loss and Delivery Problems

For orders shipped to consumers, the risk of loss remains with Kraftsense until the product is delivered to the shipping address provided in the order, except where applicable law provides otherwise.

You are responsible for providing an accurate and deliverable address.

If tracking shows delivery but you cannot locate the package, contact us promptly at support@kraftsensetool.com.

We may ask you to:

• verify the shipping address;

• check with household members, neighbors, reception areas, or property management;

• contact the carrier;

• provide a written statement; or

• cooperate with a carrier or insurance investigation.

We will evaluate lost, misdelivered, or damaged shipment claims based on the available evidence and applicable law.

A carrier’s delivery scan does not automatically eliminate rights relating to a shipment that was not actually delivered to the correct address.

9. Title to Products

Title to purchased products passes to the customer upon full payment and delivery, unless applicable law requires a different result.

Any reservation of title is limited to the extent permitted by applicable law.

10. Returns, Refunds, and Exchanges

Returns, refunds, exchanges, and return shipping costs are governed by our separately published Return and Refund Policy.

Our current voluntary return period is generally 30 days after receipt, subject to the conditions and exclusions stated in that policy.

The Return and Refund Policy forms part of these Terms.

A voluntary return policy does not limit rights that may apply to defective, damaged, misrepresented, recalled, or incorrectly delivered products.

Products purchased from Amazon, Walmart, another marketplace, or another retailer are generally subject to the original seller’s return procedures, although separate Kraftsense warranty rights may apply.

11. Batteries and Battery-Powered Products

Some Kraftsense products contain or are supplied with lithium-ion batteries.

Customers must follow all product instructions concerning:

• charging;

• compatible chargers;

• storage;

• temperature;

• transportation;

• inspection;

• maintenance; and

• disposal.

Do not use or charge a battery that is swollen, leaking, punctured, crushed, overheated, burned, producing an unusual odor, or otherwise damaged.

Do not ship a damaged or potentially unsafe lithium-ion battery through an ordinary parcel service without receiving appropriate instructions.

Contact support@kraftsensetool.com for return, collection, recycling, or disposal guidance.

Customers must not modify, dismantle, short-circuit, puncture, burn, or use batteries with incompatible equipment.

These safety instructions do not limit rights relating to a defective or unsafe product.

12. Product Warranties and Remedies

Products may be covered by a written limited warranty described on the product page, in the product packaging, in the product manual, or in a separate warranty document.

Any written product warranty is in addition to rights that cannot be waived under applicable law.

If a product is defective, damaged, incomplete, or materially different from its description, contact support@kraftsensetool.com and provide:

• the order number;

• the model and serial number, where applicable;

• a description of the issue;

• photographs or video where reasonably useful; and

• any relevant troubleshooting information.

Depending on the circumstances, an available remedy may include:

• technical support;

• replacement parts;

• repair;

• replacement;

• refund; or

• another remedy required by applicable law or the applicable written warranty.

Requests for photographs, video, or troubleshooting information are intended to help evaluate the claim and do not eliminate non-waivable legal rights.

13. Website Availability and Disclaimer

We aim to keep the website available, accurate, and secure, but we do not guarantee that access will always be uninterrupted or error-free.

The website, general informational content, account features, and optional digital tools are provided on an “as available” basis.

To the maximum extent permitted by law, we disclaim warranties relating solely to website availability, uninterrupted access, or freedom from technical errors.

This disclaimer does not:

• disclaim an express written product warranty;

• exclude warranties that cannot legally be disclaimed;

• limit rights relating to defective or nonconforming products;

• exclude liability for fraud or intentional misconduct; or

• limit rights provided by applicable consumer protection law.

Some jurisdictions do not allow certain warranty exclusions, so some exclusions may not apply to you.

14. Limitation of Liability

Nothing in these Terms excludes or limits liability that cannot legally be excluded or limited.

To the fullest extent permitted by applicable law, Kraftsense and its affiliates, officers, employees, contractors, and service providers will not be liable for indirect, incidental, special, exemplary, punitive, or consequential damages arising from use of the website or purchase of a product.

This exclusion does not apply to the extent a claim arises from:

• fraud or fraudulent misrepresentation;

• willful misconduct;

• gross negligence where liability cannot be limited;

• death or personal injury;

• violation of a non-waivable statutory right;

• product liability that cannot be excluded;

• breach of an applicable written warranty; or

• any other liability that applicable law does not permit us to exclude.

Where liability may legally be limited, our aggregate liability for a claim relating to a product will not exceed the greater of:

• the amount paid for the affected product; or

• any minimum amount required by applicable law.

Some states do not permit the exclusion or limitation of certain damages. In those states, these limitations apply only to the extent permitted by law.

15. Intellectual Property

The website and its contents—including text, graphics, logos, photographs, videos, product illustrations, designs, software, and trademarks—are owned by or licensed to Kraftsense and are protected by applicable intellectual property laws.

We grant you a limited, revocable, non-exclusive, non-transferable right to access and use the website for personal and lawful shopping purposes.

Unless permitted by law or authorized in writing, you may not:

• reproduce or distribute website content;

• commercially exploit website content;

• modify or create derivative works;

• remove ownership or rights notices;

• use our trademarks in a misleading manner; or

• imply sponsorship, endorsement, or affiliation without authorization.

Nothing in these Terms transfers ownership of any intellectual property to you.

16. Reviews, Feedback, and User Content

You may choose to submit reviews, photographs, comments, suggestions, or other content.

You retain ownership of content you create.

By submitting content to us, you grant Kraftsense a non-exclusive, worldwide, royalty-free license to host, reproduce, display, format, distribute, and use the content for operating, improving, and promoting our products and Services.

This license applies only to the extent permitted by law and does not transfer ownership of your content.

You represent that:

• you created the content or have permission to submit it;

• it does not violate another person’s intellectual property, privacy, or publicity rights;

• it is not knowingly false or misleading;

• it does not contain malware or unlawful material; and

• you disclose any material incentive or relationship connected with a review or endorsement.

We may remove content that is unlawful, fraudulent, abusive, irrelevant, infringing, deceptive, or technically harmful.

We will not prohibit or penalize a customer merely for posting an honest review, including a negative review.

We are not required to publish every submitted review or retain it indefinitely.

17. Prohibited Uses

You may use the Services only for lawful purposes.

You may not:

• violate applicable law;

• commit fraud or misrepresent your identity;

• interfere with the security or operation of the website;

• introduce malware or harmful code;

• gain unauthorized access to accounts, systems, or data;

• collect personal information without authorization;

• infringe intellectual property or privacy rights;

• submit unlawful, threatening, defamatory, or abusive content;

• use the Services to send spam or deceptive communications;

• circumvent purchase limits, security controls, or fraud controls;

• use automated systems in a manner that overloads, damages, or materially interferes with the Services; or

• purchase products for unlawful export, resale, or prohibited use.

We may restrict access when reasonably necessary to protect customers, Kraftsense, Shopify, payment providers, service providers, or the security and lawful operation of the Services.

18. Third-Party Services and Links

The Services may include payment providers, shipping providers, embedded features, applications, or links operated by third parties.

Third-party services may be governed by their own terms and privacy policies.

We are not responsible for the independent content, availability, or business practices of third-party websites that we do not control.

However, using a third-party service provider does not eliminate Kraftsense’s responsibilities for its own obligations under an accepted order.

19. Relationship With Shopify

The online store is hosted and supported by Shopify.

Purchases of Kraftsense products through kraftsensetool.com are made between the customer and Kunheng HongKong Limited, not Shopify.

Shopify is not the seller, manufacturer, warrantor, or fulfillment provider for Kraftsense products unless a particular Shopify service expressly states otherwise.

The use of Shopify does not reduce Kraftsense’s obligations relating to accepted orders, product claims, refunds, warranties, or applicable consumer rights.

20. Privacy

Our collection and use of personal information are described in our Privacy Policy.

Shopify and other service providers may process personal information to provide hosting, payment, fraud prevention, customer support, analytics, order processing, and delivery services.

Any processing requiring separate consent will be handled in accordance with applicable law.

Use of the website does not by itself constitute consent to data practices for which express consent is legally required.

21. Electronic Communications

By using the Services or providing an email address, you consent to receive transaction-related communications electronically, including:

• order acknowledgments;

• payment confirmations;

• shipping updates;

• return and refund communications;

• warranty communications;

• account and security notices; and

• legally required notices where electronic delivery is permitted.

Marketing messages will be sent only as permitted by applicable law and may be unsubscribed from using the method provided in the message.

You are responsible for keeping your email address current.

22. Errors and Corrections

We may correct typographical, technical, pricing, inventory, or product-information errors before accepting an order.

If an obvious material error is discovered after an order is submitted but before acceptance, we may correct the error and ask whether you wish to proceed, or decline the order and refund any payment received.

After an order has been accepted, we will not cancel or materially change it solely because doing so would be more convenient for us.

Any cancellation after acceptance will be handled according to applicable law and the specific circumstances.

23. Suspension and Termination of Website Access

We may suspend or terminate access to the website or a customer account when reasonably necessary because of:

• fraud or suspected fraud;

• unlawful activity;

• security threats;

• material or repeated violations of these Terms; or

• conduct that materially harms the Services or other users.

Where reasonably possible, we will provide notice and an opportunity to correct the issue.

Termination of website access does not cancel an accepted order or eliminate rights and obligations that arose before termination.

24. Informal Dispute Resolution

Before either party begins arbitration or files a lawsuit, the party asserting a dispute must first send the other party an individualized written Notice of Dispute.

A Notice sent to Kraftsense must be delivered by email to:

support@kraftsensetool.com

The subject line should state:

Notice of Dispute

The Notice must include:

• the customer’s full name;

• the customer’s billing or shipping address;

• the email address associated with the order;

• the applicable order number;

• a description of the factual and legal basis of the dispute;

• the specific relief requested;

• the amount of any monetary demand;

• and the customer’s personal signature, which may be electronic.

If the customer is represented by an attorney, both the customer and the attorney must sign the Notice.

Kraftsense will send any Notice of Dispute to the customer’s most recent email or mailing address contained in the applicable order or customer account.

After a complete Notice is received, the parties will attempt in good faith to resolve the dispute informally for 60 days.

The parties may mutually agree to extend this period.

Any applicable limitation period and filing deadline will be tolled during the 60-day informal resolution period.

Neither party may begin arbitration before completing this informal dispute-resolution process, except where immediate temporary or emergency relief is reasonably necessary to prevent imminent harm.

Failure to provide a complete and individualized Notice may be raised before the arbitrator or court when determining whether the pre-arbitration requirements have been satisfied.

25. Agreement to Mandatory Individual Arbitration

Please read this section carefully. It affects your legal rights.

Except for disputes expressly excluded below, you and Kraftsense agree that every dispute, claim, or controversy arising out of or relating to:

• these Terms;

• the Services;

• a customer account;

• an order or transaction;

• advertising or marketing;

• a Kraftsense product;

• delivery, return, refund, warranty, or customer support;

• privacy or data practices;

• or the relationship between you and Kraftsense,

will be resolved through final and binding individual arbitration rather than in court.

This agreement applies to claims based on contract, warranty, statute, regulation, ordinance, tort, fraud, misrepresentation, equity, or any other legal theory.

It also applies to disputes arising before the effective date of these Terms, except for a dispute already filed in court or arbitration before the customer accepted these Terms.

The Federal Arbitration Act, 9 U.S.C. §§ 1–16, governs the interpretation and enforcement of this arbitration agreement.

The arbitrator, and not a federal, state, or local court, will have authority to decide disputes concerning the interpretation, applicability, enforceability, or formation of this arbitration agreement, except that a court will decide:

• whether the Class Action Waiver is enforceable;

• whether the Mass Arbitration Procedures are enforceable;

• and whether a particular claim must proceed in court because applicable law prohibits its arbitration.

26. Arbitration Administrator and Procedure

The arbitration will be administered by the American Arbitration Association, or AAA, under its Consumer Arbitration Rules in effect when the arbitration is filed, as modified by these Terms.

If 25 or more substantially similar demands are filed in a coordinated manner, the AAA Mass Arbitration Supplementary Rules will also apply.

Information concerning the AAA and its applicable rules is available through the AAA.

If the AAA is unavailable or declines to administer a dispute, the parties will attempt to agree upon another nationally recognized arbitration administrator.

If the parties cannot agree, a court with lawful jurisdiction may appoint an arbitration administrator or arbitrator under the Federal Arbitration Act.

The arbitration will be conducted by one neutral arbitrator.

Unless the parties agree otherwise, the customer may choose to have the arbitration conducted:

• based only on submitted documents;

• by telephone;

• by videoconference;

• or through an in-person hearing reasonably convenient to the customer.

The arbitrator may award any individualized relief that would be available in court, including damages, statutory relief, declaratory relief, or injunctive relief, subject to the limitations in these Terms and applicable law.

The arbitrator must apply applicable substantive law and must issue a reasoned written decision sufficient to explain the essential findings and conclusions.

A court with lawful jurisdiction may enter judgment upon the arbitration award.

27. Arbitration Fees and Attorneys’ Fees

Payment of arbitration filing, administration, and arbitrator fees will be governed by the applicable AAA Consumer Arbitration Rules and fee schedule.

The customer will not be required to pay arbitration fees greater than the amount the customer would be required to pay to file the same claim in an appropriate court, unless the arbitrator determines that the claim was filed in bad faith or for an improper purpose and applicable law permits a different allocation.

Kraftsense will pay the arbitration fees that the AAA rules or applicable law require a business to pay.

Each party will generally bear its own attorneys’ fees and costs.

However, the arbitrator may award attorneys’ fees and costs when authorized by applicable law, an applicable written warranty, or these Terms.

If the arbitrator determines that a claim or requested relief was frivolous, filed in bad faith, or brought for an improper purpose, the arbitrator may allocate fees and costs to the extent permitted by applicable law and the arbitration rules.

28. Small Claims Court and Other Exceptions

Either party may bring an individual claim in a small claims court with lawful jurisdiction if the claim qualifies and remains solely within that court.

A small claims matter must proceed only on an individual basis.

Either party may also seek temporary or preliminary injunctive relief from a court when reasonably necessary to prevent imminent misuse of intellectual property, unauthorized access to systems, fraud, or other immediate and irreparable harm while arbitration is pending.

Claims concerning ownership or infringement of patents, copyrights, trademarks, trade secrets, or other intellectual property may be brought in a court with lawful jurisdiction.

Nothing in this section permits a party to pursue claims on a class, collective, consolidated, coordinated, or representative basis.

29. Class Action and Representative Action Waiver

To the fullest extent permitted by law, you and Kraftsense agree that each party may bring claims against the other only in an individual capacity.

Neither party may bring or participate in any purported:

• class action;

• class arbitration;

• collective action;

• consolidated action;

• coordinated action, except as expressly provided in the Mass Arbitration Procedures;

• representative action;

• private attorney general action on behalf of other persons;

• or proceeding in which a party seeks relief for persons who are not parties to the dispute.

The arbitrator may award relief only to the individual party seeking relief and only to the extent necessary to resolve that party’s individual claim.

The arbitrator may not combine the claims of more than one person or preside over any class, collective, consolidated, or representative proceeding unless Kraftsense and every affected claimant expressly agree in writing after the dispute arises.

If a final court decision determines that applicable law prevents enforcement of this waiver with respect to a particular claim or request for relief, only that claim or request for relief will proceed in court.

All other claims will remain subject to individual arbitration.

Under no circumstances will a claim proceed through class arbitration unless Kraftsense expressly agrees in writing after the dispute arises.

30. Mass Arbitration Procedures

The following procedures apply when 25 or more substantially similar arbitration demands are:

• filed against Kraftsense;

• submitted within a 180-day period;

• based on the same or substantially similar facts or legal theories;

• and submitted by the same law firm, coordinated law firms, or organizations acting together.

The parties agree that such demands constitute a Mass Arbitration and will be administered under the AAA Mass Arbitration Supplementary Rules.

A process arbitrator may decide preliminary administrative issues, including:

• whether the demands satisfy the definition of a Mass Arbitration;

• whether the informal dispute requirements were completed;

• whether individual demands contain sufficient information;

• whether demands are duplicative;

• and the appropriate sequencing, batching, and scheduling of proceedings.

Unless the process arbitrator directs otherwise, the parties will initially select 20 demands to proceed as test cases:

• 10 selected by the claimants; and

• 10 selected by Kraftsense.

All remaining demands will be administratively stayed.

Limitation periods for the stayed demands will be tolled while the staged process is pending.

After the first 20 test cases are resolved, the parties will participate in a mediation session conducted by a mutually agreed mediator or one appointed by the AAA.

If the remaining claims are not resolved through mediation, they will proceed in batches of no more than 50 demands at a time, unless the parties or the process arbitrator determine that another batch size would be more efficient and fair.

A demand included in a Mass Arbitration may not be filed simultaneously in court or with another arbitration administrator.

These procedures are intended to promote efficient and orderly resolution and do not authorize class or representative arbitration.

If a final court decision finds a particular part of this section unenforceable, the remaining portions will continue to apply to the maximum extent permitted by law.

31. Thirty-Day Right to Opt Out of Arbitration

A customer may opt out of Sections 25 through 30 by sending an individualized written opt-out notice within 30 days after the customer first accepts the version of these Terms containing the arbitration agreement.

The opt-out notice must be emailed to:

support@kraftsensetool.com

The subject line must state:

Arbitration Opt-Out

The notice must include:

• the customer’s full name;

• mailing address;

• email address;

• order number, if available;

• and a clear statement that the customer chooses to opt out of the arbitration agreement.

The opt-out request must be submitted personally by the customer and must apply only to that customer.

Opting out of arbitration will not affect the customer’s order, account, pricing, or ability to purchase Kraftsense products.

A customer who does not timely opt out will be bound by the arbitration agreement, subject to applicable law.

32. Jury Trial Waiver

For any dispute that is properly resolved through arbitration, you and Kraftsense knowingly and voluntarily waive the right to a trial before a judge or jury.

For any dispute that is not subject to arbitration and is filed in court, each party waives a jury trial to the fullest extent permitted by applicable law.

If applicable law does not permit an advance jury-trial waiver, this paragraph will not apply to the extent of that prohibition.

33. Governing Law

The arbitration provisions in Sections 24 through 32 are governed by the Federal Arbitration Act.

For matters not governed by the Federal Arbitration Act, applicable federal law and the mandatory consumer-protection laws of the customer’s state of residence will apply.

Any additional choice of a particular state’s law or exclusive court venue will apply only if separately stated and legally enforceable.

Nothing in these Terms deprives a consumer of a protection that cannot lawfully be waived.

34. Severability of Arbitration Terms

Except as specifically provided in the Class Action Waiver, if any portion of Sections 24 through 33 is held invalid or unenforceable, that portion will be severed and the remaining arbitration provisions will remain in effect.

If the Class Action Waiver is finally held unenforceable in a manner that would require class or representative arbitration, the arbitration agreement will be unenforceable solely with respect to that class or representative proceeding.

The proceeding must then be brought in a court with lawful jurisdiction and not in class arbitration.
