Terms of Service

Last Updated: October 24, 2026

Welcome to Oqenv.

Oqenv is owned and operated by Hangzhou Silicon-Based Firefly Technology Co., Ltd.

These Terms of Service apply when you access our online store, browse products, place orders, or use our services.

Please read these terms together with our Shipping Policy, Return & Refund Policy, and Terms of Purchase. Our Privacy Policy explains how we collect, use, and handle personal information.

1. Store Operator

The Oqenv online store is owned and operated by Hangzhou Silicon-Based Firefly Technology Co., Ltd.

Throughout these terms, "Oqenv," "we," "us," and "our" refer to Hangzhou Silicon-Based Firefly Technology Co., Ltd., operating under the Oqenv brand.

The company is responsible for managing product sales, order processing, payment coordination, shipping, customer support, returns, refunds, and related after-sales services.

2. Website Use

When using our website, you agree to:

• Provide accurate and complete information when placing orders or requesting assistance.

• Use the website only for lawful purposes.

• Keep any account login details confidential.

• Avoid interfering with website security, operation, or functionality.

• Comply with applicable laws and these Terms of Service.

You must be legally able to enter into a purchase agreement or have appropriate authorization to do so.

We may restrict access where reasonably necessary to address fraud, security threats, unlawful conduct, or misuse.

Such restrictions do not remove our obligations concerning existing purchases, approved refunds, or valid customer support requests.

3. Product Information

We make reasonable efforts to provide accurate product descriptions, images, specifications, prices, and availability information.

Minor visual differences may result from lighting conditions, screen settings, or normal manufacturing variations.

These differences do not excuse supplying an incorrect, defective, or materially misdescribed product.

If a product you receive is materially different from its description, please contact us for assistance under our Return & Refund Policy.

4. Orders and Acceptance

Please review your selected products, quantities, available options, shipping address, and total price before submitting an order.

An order confirmation email acknowledges receipt of your order request and does not, by itself, confirm final acceptance.

Order acceptance occurs when we send a shipping confirmation for the applicable items.

Before acceptance, we may decline or cancel an order for reasonable reasons, including:

• Unavailable inventory.

• A material pricing or product information error.

• Payment failure.

• Reasonable concerns about fraud or unauthorized payment.

• Incomplete or invalid delivery information that cannot be resolved.

We will notify you if an order cannot be accepted.

If payment has already been collected for a canceled order, we will refund the amount paid for the canceled items and any applicable shipping charges to the original payment method within 5–10 business days after cancellation confirmation.

We will not require you to accept a higher price or substitute product without your agreement.

5. Pricing and Payment

Product prices and shipping charges are displayed in USD, unless otherwise clearly indicated.

The checkout page displays the total payable amount, including applicable shipping charges and taxes collected at checkout, before you submit payment.

Price changes apply to future purchases and do not authorize us to increase the amount of an accepted order without your agreement.

You must use an authorized payment method and provide accurate billing information.

Orders are generally processed after payment confirmation.

If you believe you have been charged incorrectly or more than once, please contact service@oqenv.com so we can review the transaction.

6. Order Changes and Cancellations

If you need to modify or cancel an order, please contact service@oqenv.com as soon as possible.

Include your order number, checkout email address, and details of your request.

We will check whether your order can still be modified or canceled before dispatch.

Changes and cancellations cannot be guaranteed once fulfillment preparation has begun.

If we successfully cancel your order before dispatch:

• No cancellation fee will be charged.

• The full amount paid, including any original shipping charge, will be refunded.

• The refund will be issued to your original payment method within 5–10 business days after cancellation confirmation.

If your order has already shipped, please follow the applicable return procedures outlined in our Return & Refund Policy after delivery.

7. Shipping and Delivery

We currently ship to the United States.

Our standard shipping arrangements are as follows:

Order Processing

Orders are generally processed within 1–5 business days after payment confirmation.

Processing time is separate from the estimated shipping transit time.

Free Standard Shipping

• Order Subtotal: $39.00 USD or more.

• Shipping Cost: Free ($0.00 USD).

• Estimated Transit Time: 10–15 business days after dispatch.

Standard Shipping

• Order Subtotal: Less than $39.00 USD.

• Shipping Cost: $5.99 USD.

• Estimated Transit Time: 10–15 business days after dispatch.

The applicable shipping charge and final order total will be displayed at checkout before payment.

The combined estimated processing and shipping period is generally 11–20 business days after payment confirmation.

Business days exclude weekends and applicable public holidays.

Orders may be fulfilled through our own facilities or third-party fulfillment partners. The dispatch location may differ from our registered business address.

A United States delivery address does not necessarily mean the order will be dispatched from a warehouse located in the United States.

We will send a shipping confirmation email with tracking information after dispatch.

Delivery estimates may be affected by carrier disruptions, severe weather, holidays, customs processing where applicable, or other delivery conditions.

If a shipment is delayed, appears lost, or shows "Delivered" but cannot be located, please contact us so we can investigate and help resolve the issue.

A "Delivered" tracking status alone will not automatically result in rejection of a delivery complaint.

We do not transfer all delivery responsibility to customers when a package is handed to the carrier.

Please review our Shipping Policy for complete shipping and delivery information.

8. Returns and Refunds

Eligible returns may be requested within 14 calendar days after delivery.

For change-of-mind or preference-based returns:

• Products must be unused and in their original condition.

• Original packaging, accessories, and included components must be returned where applicable.

• Customers are responsible for applicable return shipping costs.

• Original outbound shipping charges are generally non-refundable unless required by applicable law.

We do not charge restocking fees.

If a product arrives damaged, defective, incorrect, incomplete, or materially different from its description, we will provide an appropriate replacement, refund, or return solution at no additional cost to the customer.

If a return is required because of such an issue, we will arrange a prepaid return method or cover the necessary return shipping costs.

For a full-order refund resulting from a damaged, defective, incorrect, or materially misdescribed product, we will also refund any original shipping charge paid.

Approved refunds are issued to the original payment method within the following timeframes:

• Approved Returns: 5–10 business days after the returned product has been received and inspected.

• Refunds Without a Required Return: 5–10 business days after approval.

• Successful Order Cancellations: 5–10 business days after cancellation confirmation.

Your bank, card issuer, or payment provider may require additional time to display the funds after the refund has been issued.

Please contact service@oqenv.com before sending any product back.

Our registered business address is not a return address unless our customer support team specifically authorizes it.

After your return request has been reviewed and approved, we will provide the designated return address and applicable instructions.

Please review our Return & Refund Policy for complete return eligibility requirements, procedures, and refund information.

9. Customer Responsibilities

Customers are responsible for providing accurate billing, contact, and delivery information and notifying us promptly if an error is discovered.

Products should be used according to their descriptions, instructions, and applicable safety information.

If incorrect customer-provided information causes a delivery problem, we will review the circumstances and explain the available options and any necessary additional costs before you agree to an arrangement.

Customers will not be responsible for additional shipping costs caused by our fulfillment or addressing errors.

10. Intellectual Property

Website content, including text, images, graphics, logos, product descriptions, and designs, is owned by Hangzhou Silicon-Based Firefly Technology Co., Ltd., or used under authorization from the relevant rights holders, unless otherwise stated.

You may browse the website and use its content for personal shopping purposes.

Other reproduction, distribution, modification, or commercial use requires appropriate authorization, except where permitted by applicable law.

You must not:

• Use the website to commit fraud or other unlawful acts.

• Collect other users' personal information without authorization.

• Use the website in a manner that violates applicable laws or these terms.

We may take reasonable measures to investigate and address prohibited activities.

12. Third-Party Services

We may use third-party providers to support functions such as:

• Payment processing.

• Website hosting and e-commerce operations.

• Shipping and order fulfillment.

• Website analytics and technical support.

• Customer service and communications.

• Fraud prevention and transaction security.

Third-party services may have their own terms and privacy policies governing your direct use of those services.

Using third-party providers does not remove our responsibilities to customers regarding orders, delivery assistance, returns, refunds, or applicable consumer protections.

Please review our Privacy Policy for further information about personal information handling.

13. Service Availability and Responsibility

We may maintain, update, or temporarily suspend website functions when reasonably necessary for technical, operational, or security purposes.

We will make reasonable efforts to minimize service disruptions.

Website changes or interruptions do not remove our obligations concerning accepted orders, approved refunds, or other outstanding customer matters.

We do not guarantee that the website will always operate without interruption or error.

Any limitation of responsibility applies only to the extent permitted by applicable law.

Nothing in these terms excludes or limits liability that cannot lawfully be excluded or limited, or removes mandatory consumer rights and remedies.

14. Changes to These Terms

We may update these Terms of Service to reflect changes in our services, business practices, or applicable legal requirements.

The revised version will be posted on this page with an updated Last Updated date.

Where required by applicable law, we will provide additional notice of material changes.

Updates apply prospectively and do not retroactively reduce your rights concerning an existing purchase.

The terms presented when your order was placed will continue to govern that purchase unless you agree otherwise or applicable law requires a different approach.
