These terms apply to the Cosaiy™ online store at cosaiy.com. Business and contact details are provided at the end of this page.

By accessing cosaiy.com, creating an account, or placing an order, you agree to these terms and the store policies applicable to your use or transaction.

If you do not agree to these terms, please do not use the website or submit an order. Mandatory consumer rights remain unaffected.

To make a purchase, you must be at least 18 years old or have reached the legal age required to enter into a binding purchase agreement in your place of residence.

If you have not reached the applicable legal age, you may use the store only with the involvement and permission of a parent or legal guardian.

If customer account functionality is available and you create an account, you are responsible for providing accurate information and maintaining the confidentiality of your login credentials.

Please notify us promptly if you believe your account has been accessed or used without authorization.

We make reasonable efforts to present product descriptions, photographs, dimensions, specifications, pricing, and availability accurately.

Cosaiy™ offers consumer electronics, portable audio products, and electronic accessories. Features, compatibility, power requirements, battery specifications, and included accessories vary by model and should be checked on the relevant product page.

Minor color differences may result from photography, lighting, or screen settings. Such differences do not excuse a materially inaccurate description, functional defect, or incorrect product.

Submitting an order is a request to purchase the selected products. An automated order acknowledgment confirms receipt of that request and does not by itself guarantee availability or acceptance.

Acceptance occurs when we confirm shipment or otherwise expressly accept the order. Orders may be subject to stock availability, payment authorization, and reasonable verification.

If an order cannot be accepted or fulfilled, we will notify you and refund any collected payment for canceled items.

Prices are displayed in U.S. dollars (USD) unless another currency is clearly shown. Applicable shipping charges, taxes collected, discounts, and the final order total are displayed before payment.

Available payment methods appear at checkout. Your bank or payment provider may impose separate currency-conversion or transaction fees.

If a material pricing error is discovered, we will contact you rather than charge an increased amount without your agreement. Additional details are available in Payment & Security.

Orders are normally processed within 2–4 business days after payment confirmation. During holidays, promotions, or unusually busy periods, processing may require up to 5 business days.

For standard shipping to supported United States destinations, estimated carrier transit is generally 10–15 business days after dispatch.

Delivery estimates are not guaranteed arrival dates. Applicable shipping options and charges are displayed during checkout. Full details are available in our Shipping Policy.

Eligible products may be returned within 30 calendar days after confirmed delivery, subject to the applicable return requirements.

After an approved return has been received, inspected, and approved, we will initiate the eligible refund to the original payment method within 5–10 business days. The payment provider may require additional time to post the credit.

No restocking fee is charged for an approved return. Return-shipping and original-shipping treatment depends on the reason for the return.

Full details are available in our Return & Refund Policy .

Please inspect your order promptly after delivery. If an item arrives damaged, defective, incomplete, incorrect, or materially different from its description, contact us promptly, preferably within 7 calendar days after delivery.

Include your order number and relevant photographs or videos showing the product, issue, packaging, and shipping label where appropriate. Do not continue testing an unsafe electronic product.

After a problem attributable to us has been reviewed and confirmed, we will provide an appropriate replacement, refund, reshipment, return, or other reasonable solution at no additional cost caused by that error. The reporting target does not limit statutory rights.

Change or cancellation requests should be submitted as soon as possible after an order is placed.

We will make reasonable efforts to assist before fulfillment begins, but a change or cancellation cannot be guaranteed after processing, fulfillment, packaging, shipment preparation, or dispatch has started.

No cancellation fee is charged when an order is successfully canceled before fulfillment.

Promotional offers and discount codes may be subject to expiration dates, eligibility requirements, minimum purchase amounts, product exclusions, availability, usage limits, or other conditions presented with the applicable offer.

Unless otherwise stated, promotions cannot be redeemed for cash and may not be combined with other offers. Discounts should be applied before checkout is completed.

Products must be used lawfully and in accordance with the applicable product description, specifications, operating instructions, and safety information.

Use compatible devices, suitable power supplies, and appropriate charging accessories. Do not exceed specified voltage or current ratings, expose products to water beyond any stated protection rating, or attempt unauthorized modifications.

Battery life, wireless range, charging speed, and other performance characteristics depend on the model and operating conditions. Any additional commercial warranty applies only where expressly stated for the product. Mandatory consumer protections remain unaffected.

Customers interested in unusually large orders, wholesale purchasing, or commercial resale should contact us before placing an order so that availability and applicable terms can be confirmed.

Purchasing products for resale does not authorize any person or business to represent itself as an official Cosaiy™ distributor, agent, representative, partner, or authorized retailer without prior written permission.

The Cosaiy™ name, branding, website design, graphics, photographs, product presentation, text, and other protected store content are subject to applicable intellectual-property rights.

You may use the website for personal shopping and other lawful purposes. Protected content may not be copied, republished, modified, distributed, or commercially exploited without appropriate permission, except where applicable law permits such use.

If the website allows you to submit a review, photograph, comment, or other content, you are responsible for ensuring that your submission is accurate, lawful, and does not infringe another person’s rights.

By voluntarily submitting content for publication, you grant us a non-exclusive, worldwide, royalty-free license to host, reproduce, and display that content in connection with operating, promoting, and improving the store, subject to applicable law and our Privacy Policy.

We may decline or remove content that is unlawful, fraudulent, threatening, abusive, misleading, infringing, contains sensitive personal information, or is unrelated to the relevant product or service. Moderation must not misrepresent genuine customer feedback.

You may not use the website to:

• Commit fraud or engage in unlawful activity.
• Submit false, misleading, or unauthorized payment information.
• Interfere with website security, operation, or availability.
• Introduce malicious code or attempt unauthorized access.
• Collect information about other users without authorization.
• Infringe intellectual-property, privacy, or other legal rights.
• Misrepresent your identity or relationship with Cosaiy™.

We may restrict access, cancel affected orders, or take other reasonable action when prohibited activity is identified, subject to applicable law and refund obligations.

Our store uses Shopify and may rely on third-party payment, shipping, analytics, communication, and other service providers.

The website may also contain links to third-party websites or services. Their products, services, content, availability, and data practices may be governed by their own terms and policies.

Severe weather, natural disasters, carrier interruptions, transportation restrictions, labor disruptions, government action, customs delays, infrastructure failure, widespread technical outages, or similar events may affect performance.

Where such an event affects an order, we will make reasonable efforts to communicate available information and provide an appropriate solution. These circumstances do not remove obligations to provide notices, refunds, or other remedies required by law.

To the extent permitted by applicable law, the website and store services are provided without warranties beyond those expressly stated or legally required.

To the extent permitted by applicable law, liability for indirect, incidental, special, consequential, exemplary, or punitive damages arising from use of the website, a transaction, or product use may be limited.

Nothing in these terms excludes or restricts consumer rights, remedies, warranties, or liabilities that applicable law does not permit to be excluded or restricted.

These terms and purchases made through the store are subject to applicable law, including any mandatory consumer-protection rights that apply based on the transaction or customer’s location.

If a dispute arises, we encourage you to contact customer support first so that both parties can attempt to resolve the matter in good faith.

Nothing in this section prevents either party from using rights or remedies available under applicable law.

If any provision of these terms is found to be invalid or unenforceable, the remaining provisions will continue to apply to the extent permitted by law.

A delay or failure to enforce a provision does not necessarily waive the right to enforce that or another provision later.

We may revise these terms when our services, business practices, technology, store policies, or applicable requirements change.

The current version will be posted on cosaiy.com. Unless applicable law requires otherwise, the version in effect when an order is submitted generally applies to that transaction.
