Shipping and Returns

Last updated: August 29, 2026

This policy applies to SereniBrain products ordered directly from serenibrain.com. Purchases made through Amazon or another marketplace must be returned through that marketplace and are also subject to its order and return rules.

Where we ship

Direct website orders are currently available for delivery within the United States. We do not currently accept direct website orders for delivery outside the United States.

Order processing and delivery

  • Orders are normally processed within 1–3 business days.
  • Estimated U.S. standard delivery is 5–10 business days after dispatch.
  • Where offered at checkout, estimated U.S. express delivery is 2–3 business days after dispatch.

Business days exclude weekends and public holidays. Delivery estimates are not guarantees and may be affected by inventory, carrier delays, weather, address issues, or other events outside our control.

Direct website orders may be fulfilled using Amazon fulfillment and logistics services. When your order ships, tracking information will be sent to the email address used at checkout.

Shipping charges and addresses

Available shipping methods and charges are shown at checkout. Please check the shipping address before placing your order. Contact support@serenibrain.com as soon as possible if an address needs to be corrected. We cannot guarantee an address change after fulfillment has started.

30-day returns

You may request a return within 30 days after delivery. To be eligible, the headband and included accessories must be returned in their original condition, with the original packaging, and without damage caused by misuse or improper handling.

Before sending anything back, email support@serenibrain.com with your order number and reason for return. We will provide return instructions and, where applicable, create a return label through the fulfillment system.

Change-of-mind returns

If the return is requested for a personal reason, including changing your mind, ordering by mistake, or selecting the wrong item, the customer is responsible for return postage. Any return label we provide for this type of return is not prepaid unless we state otherwise in writing.

Damaged, defective, incorrect, or incomplete orders

If an item arrives damaged, defective, incorrect, or with missing accessories, contact us before returning it. Please include the order number and clear photos or video where possible. After reviewing the issue, we will provide an appropriate solution, which may include troubleshooting, replacement parts, a replacement device, return instructions, or a refund, depending on the circumstances and applicable law.

Refunds

Refunds are issued to the original payment method after the returned item is received and inspected. Original shipping charges and change-of-mind return costs are not refundable unless required by law or confirmed by us in writing. Your bank or payment provider may require additional time to post the refund.

Amazon purchases

If you purchased SereniBrain on Amazon, start the return from “Your Orders” in your Amazon account. Amazon’s return window, label, refund, and eligibility rules shown for that order will apply.

Delayed, lost, or marked-delivered packages

Check the carrier tracking page and delivery location first. If tracking has not updated for several days, or the package appears lost or incorrectly delivered, contact us with your order number and tracking number so we can help investigate.
