1. Our business and these terms

Tethira is the store brand operated at tethira.com by RAY POWER TECHNOLOGY TRADING LIMITED ("we", "us", or "our"). This company is the seller and contracting party for purchases made from this store. By using our site or placing an order, you agree to these Terms of Service and the policies linked below. Nothing in these terms excludes or limits mandatory consumer rights.

2. Using our store

You must be legally able to enter a contract in your jurisdiction. Do not use the site or our products for an unlawful purpose or infringe the rights of others. Provide accurate and current contact, billing, and delivery information.

3. Products, prices, and orders

Product descriptions, selected options, prices, availability, shipping charges, taxes collected by us, and the order total are displayed before payment. Review them before placing an order. Product colors can vary with lighting and screen settings. Prices and availability may change for future orders. We may refuse or cancel orders where permitted by law, including for suspected fraud or a material pricing or stock error; if payment has been collected for a canceled order, we will provide the appropriate refund.

4. Shipping, returns, and cancellations

Our Shipping & Delivery Policy explains processing, transit estimates, charges, and delivery support. Our Return & Refund Policy explains the 30-day return request window, eligibility, authorized return address, and refund process.

5. Privacy and third parties

Our store is hosted on Shopify. Our Privacy Policy explains how personal information is collected, used, and shared and how to contact us about privacy rights. Independent third-party sites and services are subject to their own terms. Nothing in this section removes any responsibility we have under applicable law.

6. Liability

To the extent permitted by law, we are not liable for indirect, incidental, special, punitive, or consequential losses arising from use of our site or products. This does not exclude liability or remedies that cannot lawfully be excluded, including any mandatory rights relating to defective or nonconforming goods.

7. Governing law

These terms are governed by the laws of the Hong Kong Special Administrative Region, without overriding any mandatory consumer protections that apply in your place of residence.
