TERMS OF SERVICE

OVERVIEW

This website is operated under the Stemora brand by Storevia Limited. Throughout this website, the terms “Stemora,” “we,” “us,” and “our” refer to Storevia Limited and the Stemora online store, as applicable.

Stemora provides this website, including the information, content, features, products, customer support, and other services made available through https://stemora.us, subject to these Terms of Service.

EDUCATIONAL USE AND PROFESSIONAL LIMITATIONS

Products described as laboratory, specimen, microscope, measurement, electronics, robotics, safety, or scientific supplies are not automatically suitable for professional, medical, clinical, industrial, regulatory, or safety-critical use.

References to “lab,” “laboratory,” “specimen,” “centrifuge,” “safety,” “medical-style,” or similar terms may describe a product’s general format or educational function. Such language does not establish professional certification, sterility, medical approval, or suitability for a regulated application.

PRODUCT SAFETY

Customers must read and follow all product instructions, warnings, age recommendations, compatibility requirements, and safety guidance.

Adult or qualified instructor supervision may be required when products involve:

• Electricity or batteries
• Heat or heated surfaces
• Glass or breakable components

• Motors and moving mechanisms
• Soldering or heated tools

Customers are responsible for selecting a safe workspace, using appropriate protective equipment, maintaining supervision, and keeping unsuitable products away from children and vulnerable persons.

Do not use a product outside its stated purpose or operating limits. Stop using any product that appears damaged, overheated, swollen, cracked, contaminated, unstable, or otherwise unsafe.

PRODUCT COMPATIBILITY

Many products sold by Stemora require compatibility with specific equipment, dimensions, voltages, connectors, software, operating systems, thread sizes, mounting patterns, or other components.

Before purchasing, customers should review relevant information such as:

• Product dimensions
• Model or board version
• Input and output voltage
• Current requirements
• Connector type
• Pin arrangement
• Thread type
• Printer dimensions
• Nozzle or filament size
• Microscope size
• Software and operating-system requirements
• Required tools and separately sold components

Similar-looking products may not be interchangeable.

We may provide general product information or assistance, but unless expressly confirmed in writing, we do not guarantee compatibility with every device, project, platform, or third-party product. Customers remain responsible for determining whether a product is appropriate for their intended use.

PRODUCT INFORMATION

We make reasonable efforts to present product descriptions, photographs, specifications, dimensions, colors, included components, prices, and availability accurately.

However:

• Colors may appear differently depending on the screen or lighting
• Dimensions may include reasonable manufacturing tolerances
• Packaging may change
• Product appearance may be updated
• Manufacturer specifications may change
• Accessories shown for demonstration may not be included
• Natural or assorted items may vary
• Images may show multiple products or possible uses
• Product titles may summarize rather than list every specification

The product description, specification table, variant selection, and included-items information should be reviewed together before purchase.

If we discover a material error affecting an order before shipment, we may contact the customer to confirm whether they wish to proceed with corrected information or cancel the affected item for a refund.

INFORMATION ACCURACY

Information provided on the website is intended to assist customers but should not be treated as professional medical, scientific, engineering, legal, safety, or regulatory advice.

We may correct typographical errors, inaccurate descriptions, missing information, pricing errors, availability errors, and other mistakes.

We will not rely on these Terms to enforce information we knew, or reasonably should have known, was materially false or misleading. Nothing in these Terms limits rights arising from legally actionable misrepresentation or other rights that cannot be waived.

ORDERS AND CONTRACT FORMATION

Submitting an order is an offer to purchase the selected products under these Terms.

An automated order confirmation acknowledges receipt of the order but does not necessarily constitute final acceptance.

We may review an order for:

• Payment authorization
• Product availability
• Pricing accuracy
• Shipping eligibility
• Address verification
• Quantity limitations
• Suspected fraud
• Product restrictions
• Technical or operational errors

A sales contract is generally formed when we accept the order and begin fulfillment, ship the product, or otherwise confirm acceptance.

We reserve the right to decline or cancel an order before acceptance for legitimate reasons, including unavailable inventory, incorrect pricing, payment failure, suspected fraud, shipping restrictions, excessive quantities, or a material website error.

If we cancel a paid order or item before shipment, we will issue an appropriate refund to the original payment method.

ORDER LIMITATIONS

We may limit, reject, or cancel quantities that appear to be:

• Intended for unauthorized resale
• Fraudulent or abusive
• Excessive in relation to normal customer use
• Ordered through multiple accounts to bypass restrictions
• Prohibited by law or carrier requirements
• Likely to create an unreasonable safety or fulfillment risk

Any quantity limitation will be applied on a reasonable basis and subject to applicable law.

PRICES

Prices are displayed in the currency identified on the website or at checkout.

Product prices may change without prior notice. A price change does not normally affect an order already accepted, except where correction is required because of an obvious or material pricing error and applicable law permits the correction.

If a product is displayed at an obviously incorrect price, we may:

• Contact the customer and request confirmation at the correct price
• Cancel the affected item
• Refund amounts paid for the canceled item

We will not charge a higher price without the customer’s authorization.

DISCOUNTS AND PROMOTIONS

Discount codes, promotional prices, gifts, bundles, and free-shipping offers may be subject to additional conditions.

Unless otherwise stated:

• Promotions cannot be combined
• A discount has no cash value
• Expired offers cannot be applied
• Codes may be limited by product, customer, quantity, or date
• A promotion may be withdrawn before an order is placed
• Fraudulent or unintended use may be rejected

Refunds for discounted or bundled purchases will be based on the amount actually paid and the terms of the promotion.

TAXES, DUTIES, AND FEES

Customers are responsible for taxes, duties, customs charges, brokerage fees, import fees, and other government or third-party charges unless they are expressly included at checkout.

The amount collected at checkout may be based on available information and may be adjusted where required by law.

International customers are responsible for determining whether products may lawfully be imported, possessed, and used in their jurisdiction.

We will not intentionally falsify customs values, product descriptions, or shipment purposes to avoid duties or legal requirements.

PAYMENT

Payment methods available at checkout may be provided by third-party payment processors.

By submitting payment information, you represent that:

• You are authorized to use the selected payment method
• The billing information is accurate
• The transaction is lawful
• Sufficient funds or credit are available

Payment may be authorized or charged before shipment. A payment authorization does not guarantee that the order will be accepted.

We may cancel or hold an order where payment cannot be verified or where fraud, unauthorized use, or another material risk is reasonably suspected.

PAYMENT SECURITY

We use third-party platforms and payment processors to facilitate transactions. Payment information may be collected, processed, and stored under their respective terms and privacy practices.

No online transmission or storage system can be guaranteed to be completely secure. Customers should use a secure device and network and should not send complete payment-card numbers, account passwords, or unnecessary sensitive information through ordinary email.

If you suspect unauthorized account or payment activity, contact your financial institution and notify us promptly.

SHIPPING AND DELIVERY

Shipping and delivery are governed by our Shipping & Delivery Policy, which is incorporated into these Terms.

Processing and delivery dates are estimates unless expressly identified as guaranteed. If an order cannot be shipped within a promised period, we will provide the notices, delay options, cancellation rights, or refunds required by applicable law.

Orders may be divided into multiple shipments and may be fulfilled from different locations.

Customers are responsible for providing a complete and accurate delivery address and reviewing tracking information.

RETURNS, REFUNDS, AND CANCELLATIONS

Returns, refunds, replacements, exchanges, and cancellations are governed by our Return & Refund Policy, which is incorporated into these Terms.

Return approval may depend on:

• The date of the request
• Product condition
• Reason for return
• Product type
• Included components
• Compliance with return instructions
• Applicable consumer protection law

Nothing in our Return & Refund Policy limits remedies that cannot lawfully be excluded.

ACCOUNTS

Certain website functions may allow or require customers to create an account.

You are responsible for:

• Providing accurate account information
• Maintaining the confidentiality of login credentials
• Restricting access to your device and account
• Updating information when necessary
• Notifying us of suspected unauthorized access

You may not impersonate another person, create an account using false information, or use another person’s account without authorization.

We may suspend or terminate accounts reasonably associated with fraud, unlawful activity, abuse, repeated policy violations, or security threats.

CUSTOMER COMMUNICATIONS

By providing contact information, you authorize us to use it for transactional communications related to:

• Order confirmation
• Payment issues
• Shipping and tracking
• Delivery problems
• Returns and refunds
• Customer support
• Product safety or recall notices
• Changes materially affecting an order

Marketing messages will be handled according to applicable law and available consent or opt-out controls.

You are responsible for keeping your contact information accurate and reviewing communications related to your order.

USER CONTENT

The website may allow customers to submit reviews, photographs, comments, questions, feedback, or other material.

You retain ownership of content you create, but by voluntarily submitting content for public display, you grant Stemora a non-exclusive, worldwide, royalty-free license to host, reproduce, format, display, and use that content for operating and promoting the website, subject to applicable law and our Privacy Policy.

You represent that submitted content:

• Is accurate to the best of your knowledge
• Does not infringe another person’s rights
• Does not contain unlawful, threatening, defamatory, obscene, or deceptive material
• Does not contain malware or harmful code
• Does not disclose another person’s private information without authorization
• Does not falsely claim experience with a product

We may moderate or remove content that violates these Terms, but we are not obligated to publish every submission.

REVIEWS AND ENDORSEMENTS

Reviews must reflect genuine experiences and must not be misleading.

Users may not:

• Submit fake reviews
• Review products they have not used while claiming otherwise
• Offer undisclosed compensation for positive reviews
• Coordinate deceptive review activity
• Misrepresent material relationships
• Threaten or coerce another person regarding a review

We may identify verified purchases or disclose incentives where appropriate. We reserve the right to remove reviews that violate these Terms, applicable law, or platform requirements.

INTELLECTUAL PROPERTY

Unless otherwise stated, the website and its content, including the Stemora name, logos, graphics, layout, product-page text, photographs owned by us, icons, designs, and original written material, are owned by or licensed to Stemora or Storevia Limited and are protected by applicable intellectual property laws.

You may access website content for personal, non-commercial shopping and informational use.

Without prior written permission, you may not:

• Copy or republish substantial website content
• Use our branding to imply affiliation
• Create confusingly similar storefronts
• Scrape or reproduce protected content for resale
• Remove copyright or ownership notices
• Use our content in misleading advertising
• Sell counterfeit products using our name

Third-party trademarks, product names, and images remain the property of their respective owners. Their appearance does not necessarily imply sponsorship, endorsement, or affiliation.

INTELLECTUAL PROPERTY COMPLAINTS

If you believe content or a product listing on our website infringes intellectual property rights, contact:

Email: vaioamaonaoak@gmail.com

Please provide:

• Your name and contact information
• Identification of the protected work or right
• The specific webpage or product listing
• An explanation of the claimed infringement
• Evidence of ownership or authorization
• A good-faith statement regarding the complaint
• Any additional information reasonably necessary for review

We may remove, restrict, or investigate disputed content while reviewing a sufficiently supported complaint.

Submitting knowingly false claims may create legal liability.

THIRD-PARTY TOOLS AND SERVICES

The website may depend on third-party providers for hosting, payments, analytics, shipping, customer support, fraud prevention, or other functions.

Third-party tools may be subject to separate terms and privacy policies. We are not responsible for a third party’s independent conduct except to the extent liability cannot lawfully be excluded or the third party acts on our behalf in a manner for which we are legally responsible.

We may change service providers or discontinue optional website functions without guaranteeing uninterrupted availability.

THIRD-PARTY LINKS

The website may contain links to third-party websites or resources.

A link does not automatically mean that Stemora endorses, controls, or guarantees the third party. Customers should review the third party’s terms, privacy practices, pricing, and security before using its services.

We are not responsible for transactions independently completed with third parties through external websites, except where applicable law provides otherwise.

PRIVACY

Our collection, use, disclosure, retention, and protection of personal information are described in our Privacy Policy.

By using the website, you acknowledge that information may be processed as described in that policy.

These Terms do not authorize us to use personal information in a way that conflicts with applicable privacy law or the representations made in our Privacy Policy.

PROHIBITED ACTIVITIES

You may not:

• Interfere with website operation or security
• Attempt unauthorized access
• Introduce malware, bots, or harmful code
• Scrape the website in violation of law or technical restrictions
• Circumvent purchasing limits
• Use stolen payment information
• Submit fraudulent refund or delivery claims
• Harass customers, staff, or service providers
• Use the website for unlawful surveillance
• Collect user information without authorization
• Reverse engineer protected website components where prohibited
• Misrepresent your identity or affiliation
• Violate export controls, sanctions, or product restrictions

We may cooperate with payment providers, carriers, regulators, and law enforcement where lawfully required or reasonably necessary to investigate suspected fraud or unlawful conduct.

SERVICE AVAILABILITY

We aim to maintain website availability but do not guarantee uninterrupted, error-free, or continuously secure access.

The website may be temporarily unavailable because of:

• Maintenance
• Technical faults
• Security events
• Provider outages
• Network disruptions
• Legal restrictions
• Events outside our reasonable control

We may modify, suspend, or discontinue a website feature. If a change materially affects an accepted and paid order, we will provide an appropriate remedy as required by applicable law.

DISCLAIMER OF WARRANTIES

To the fullest extent permitted by applicable law, the website and general informational content are provided on an “as available” basis.

We do not guarantee that:

• The website will always be uninterrupted or error-free
• Every product will always remain available
• General website content will be suitable for every project
• A product will work with unspecified third-party equipment
• Educational materials will achieve a particular learning result
• A prototype or experiment will produce a particular outcome

Product-specific warranties, if any, are described in the relevant product materials or provided by the manufacturer.

This section does not exclude express promises we make, remedies for materially misdescribed products, statutory consumer guarantees, or warranties that cannot lawfully be excluded.

LIMITATION OF LIABILITY

To the fullest extent permitted by applicable law, Stemora and Storevia Limited will not be liable for indirect, incidental, special, punitive, or consequential losses arising from use of the website or products where such losses were not reasonably foreseeable or were caused by misuse, unauthorized modification, incompatible equipment, or failure to follow instructions.

Where liability may lawfully be limited, our total liability relating to a particular purchase will not exceed the amount paid for the product giving rise to the claim.

These limitations do not apply to:

• Fraud or fraudulent misrepresentation
• Willful misconduct
• Gross negligence where it cannot be limited
• Death or personal injury where liability cannot be excluded
• Breach of non-waivable consumer rights
• Any liability that applicable law prohibits us from limiting

Customers are responsible for backing up code, designs, measurements, settings, and project data before using products that could affect them.

CUSTOMER RESPONSIBILITY

Customers are responsible for:

• Selecting suitable products
• Reviewing specifications and compatibility
• Following instructions and warnings
• Providing appropriate supervision
• Using products within rated limits
• Confirming local legal requirements
• Using suitable protective equipment
• Inspecting products before use
• Stopping use if a product appears unsafe
• Keeping small parts and dangerous tools away from children

Customers must not remove safety devices, bypass protective features, exceed electrical ratings, or use educational products for dangerous or unlawful purposes.

INDEMNIFICATION

To the extent permitted by applicable law, you agree to be responsible for losses, claims, or reasonable costs arising directly from your unlawful use of the website, infringement of another person’s rights, fraudulent conduct, or material breach of these Terms.

This provision does not require a consumer to indemnify us for Stemora’s own negligence, breach of contract, legal violation, or other conduct for which liability cannot lawfully be transferred.

FORCE MAJEURE

We are not responsible for delay or failure caused by events beyond our reasonable control, including natural disasters, severe weather, war, civil unrest, government action, epidemics, labor disruptions, transportation interruptions, carrier failures, utility outages, cyber incidents, or supplier disruptions.

This provision does not remove obligations to provide notices, cancellation rights, refunds, or other remedies required by applicable law.

SUSPENSION AND TERMINATION

We may suspend or terminate website access where reasonably necessary to address:

• Fraud
• Unlawful conduct
• Security threats
• Abusive behavior
• Repeated policy violations
• Unauthorized access
• Material breach of these Terms

Termination does not eliminate rights or obligations that arose before termination, including payment obligations, refund rights, intellectual property rights, and provisions intended to survive.

SEVERABILITY

If any provision of these Terms is found invalid, unlawful, or unenforceable, that provision will be interpreted or limited to the minimum extent necessary, and the remaining provisions will continue to apply where legally permitted.

NO WAIVER

A delay or failure to enforce a provision does not waive the right to enforce it later.

A waiver is effective only for the specific matter for which it is given and does not waive future rights unless expressly stated in writing.

ASSIGNMENT

You may not transfer your rights or obligations under these Terms without our prior written consent where such consent may lawfully be required.

We may transfer our rights or obligations in connection with a merger, reorganization, sale, service-provider arrangement, or transfer of business, provided that doing so does not unlawfully reduce the customer’s rights.

ENTIRE AGREEMENT

These Terms and the policies incorporated by reference constitute the agreement between the customer and Stemora regarding use of the website and purchases made through it.

Product-specific terms, written order confirmations, and mandatory legal rights may supplement these Terms.

If a product-specific term conflicts with a general provision, the more specific term will apply to that product to the extent legally permitted.

GOVERNING LAW

These Terms are generally governed by the laws of Hong Kong, without regard to conflict-of-law principles.

However, this choice of law does not deprive a consumer of mandatory protections available under the laws that lawfully apply in the consumer’s place of residence or delivery.

Any dispute may be brought before a court or other forum having lawful jurisdiction. Nothing in these Terms prevents either party from using a government consumer-protection process, payment-provider process, or small-claims procedure where legally available.

DISPUTE RESOLUTION

Before beginning formal proceedings, customers are encouraged to contact us and provide a reasonable opportunity to investigate the concern.

Please include:

• Your order number
• A description of the issue
• The requested resolution
• Relevant evidence or correspondence

This informal process does not prevent either party from seeking urgent relief or exercising a legal right within an applicable deadline.

These Terms do not require mandatory arbitration and do not waive any right that cannot lawfully be waived.

CHANGES TO THESE TERMS

We may update these Terms to reflect changes in our website, products, operations, service providers, policies, or legal requirements.

Updated Terms will be posted on this page with a revised “Last updated” date.

Changes generally apply prospectively. The Terms applicable to a completed purchase will generally be those in effect when the order was placed, unless a later version provides more favorable terms or applicable law requires otherwise.

Continued use of the website after updated Terms become effective constitutes acceptance of the updated Terms for future use, to the extent permitted by law.
