Purchase Options Cancellation Policy

Last updated: April 22, 2026

This Purchase Options Cancellation Policy applies only to purchase options offered directly through the official Sentorise website, including where applicable one-time purchases, pre-orders, backorders, deposits, subscriptions, installment arrangements, or other purchase options made available at checkout or on product pages.

Sentorise products may also be available through Amazon, other online marketplaces, distributors, resellers, or third-party sales channels. Orders placed through those channels may be subject to the applicable cancellation, return, refund, subscription, and customer service procedures of the relevant platform or sales channel.

1. One-Time Purchases

Unless expressly stated otherwise on the product page or at checkout, products sold through this website are sold as one-time purchases.

If you wish to cancel a one-time purchase, please contact us as soon as possible. Cancellation may be possible before the order has entered fulfillment, packing, dispatch, or carrier handover.

Once an order has been processed, packed, shipped, or handed over to a carrier, cancellation may no longer be possible. In that case, the order may need to be handled under our Return and Refund Policy.

2. Pre-Orders and Backorders

From time to time, we may offer products on a pre-order or backorder basis.

If a product is offered as a pre-order or backorder, the estimated shipping date or availability period may be shown on the product page, checkout page, order confirmation, or customer communication.

Estimated shipping dates are estimates only and may change due to manufacturing schedules, inventory transfers, customs procedures, transport arrangements, carrier limitations, or other operational factors.

You may request cancellation of a pre-order or backorder before the order enters fulfillment, unless the product has been specially arranged, customized, reserved, or otherwise stated at the time of purchase.

3. Deposits and Partial Payments

If a product is offered with a deposit, partial payment, installment, or balance payment arrangement, the specific payment terms will be displayed on the product page, checkout page, invoice, or related customer communication.

Cancellation eligibility may depend on whether the product has been reserved, customized, packed, shipped, or specially arranged for your order.

Refunds of deposits or partial payments, if applicable, will be assessed according to the stated purchase terms, order status, product status, and applicable law.

4. Subscriptions

If we offer subscription-based products or services in the future, the subscription terms will be displayed at checkout or in the relevant subscription offer.

Customers may cancel a subscription according to the cancellation method provided at the time of purchase or by contacting customer support.

Cancellation of a subscription will generally stop future billing, but it may not cancel or refund an order that has already been processed, packed, shipped, or handed over to a carrier.

5. Fulfillment Restrictions

Lithium batteries and related power products may be subject to shipping restrictions, carrier limitations, special handling requirements, or region-specific fulfillment arrangements.

Because of these restrictions, cancellation requests must be reviewed in light of the order status, product type, warehouse status, carrier handover status, and destination requirements.

Once a battery product has entered fulfillment or shipping preparation, cancellation may be limited or unavailable.

6. How to Request Cancellation

To request cancellation, please contact us with:

1. Order number.
2. Full name.
3. Email address used for the order.
4. Product name or model.
5. Reason for cancellation.

Please contact:

Sentorise Customer Support
Email: [email protected]

Submitting a cancellation request does not guarantee cancellation. We will review the request based on the order status and respond as soon as reasonably possible.

7. Refunds After Cancellation

If a cancellation is approved, any eligible refund will usually be issued to the original payment method.

Refund processing times may vary depending on the payment provider, bank, card issuer, or checkout platform.

Payment processing fees, service fees, shipping fees, special handling fees, or other non-refundable costs may be deducted where permitted by applicable law and where such costs have already been incurred.

8. Orders Already Shipped

If an order has already been shipped, cancellation may not be possible.

You may request a return after delivery under our Return and Refund Policy. Do not refuse delivery or return a product without contacting us first, especially for lithium battery products.

Do not return any product without prior written authorization.

Approved return instructions and the designated return address will be provided by our customer support team after review.

9. Mandatory Consumer Rights

Nothing in this Policy is intended to exclude or limit any mandatory consumer rights that may apply under the laws of your country or region. Where mandatory consumer protection laws provide additional cancellation, withdrawal, refund, or return rights, those rights remain unaffected.
