These Terms of Service govern your access to and use of leion.glass, our online store, related websites, apps, products and services (together, the “Services”). By using the Services or placing an order, you agree to these Terms. If you do not agree, do not use the Services.

These Terms incorporate our Privacy Policy, Refunds, Returns & Order Cancellation Policy, Shipping Policy and Warranty Policy. If a policy gives more specific instructions for its subject, that policy applies to that subject. Nothing in these Terms removes consumer rights that cannot be excluded under the laws applicable to your purchase.

1. Who We Are

The store is operated by LEION TECHNOLOGY PTE. LTD., trading under the LEION brand (“LEION,” “we,” “us” or “our”). Our business contact address is 65 Chulia Street, #25-03, Singapore 049513. You can contact us at support@leion.glass.

2. Eligibility and Accounts

You must be legally able to enter into a binding agreement where you live to place an order. If you create an account, you must provide accurate, current information and keep your login credentials secure. You are responsible for activity carried out through your account. Contact us promptly if you believe your account has been accessed without authorization.

3. Products and Technology

We make reasonable efforts to describe and show our products accurately. Colors and appearance can vary by screen and settings. Product features, compatibility, availability and specifications may differ by model and may be updated as products and software develop.

Translation and speech-to-text captions depend on factors such as language, speech, background noise, distance, network connection, compatible devices and app or software availability. Results can be delayed or inaccurate. The products and Services are communication aids; they are not a substitute for professional interpreting, hearing aids, emergency alert systems, medical care or other critical services. Do not rely on them as the sole source of information where an error could create a safety or health risk.

4. Orders and Acceptance

When you submit an order, you are asking to purchase the items shown in your cart at the displayed price. An order-received message confirms that we received your request; it does not prevent us from reviewing or declining an order. We may refuse or cancel an order if an item is unavailable, a listing or price contains a material error, payment cannot be authorized, the delivery address is unsupported, or we reasonably suspect fraud or unlawful activity. If we cancel an order after receiving payment, we will refund the amount paid for the cancelled items to the original payment method.

Please review your order, delivery address and any prescription details before submitting it. We will use the contact details on the order to send order and delivery updates.

5. Prices, Payment and Taxes

The price, currency, shipping charges and taxes payable through LEION will be shown at checkout before you place your order. You authorize us and our payment providers to charge the payment method you select for the total shown at checkout. Prices and promotions may change, but a change will not alter an order we have already accepted unless you agree or the law allows it.

Import duties, brokerage fees and taxes charged directly by customs or a carrier are handled as described in our Shipping Policy. Taxes collected by LEION are handled as required by applicable law.

6. Pre-Orders, Shipping Dates and Delays

A shipping or availability date shown for a pre-order is an estimate unless the product listing expressly says otherwise. If we learn that we cannot ship within the time stated when you order, we will notify you of the delay and, where required by law, ask you to agree to a revised shipping date or offer cancellation and a refund for the unshipped items. A revised estimate does not remove your right to cancel a non-custom order before it ships.

For shipping areas, charges, delivery estimates, tracking, customs, address restrictions and prescription-order timing, see our Shipping Policy. Glasses and prescription lenses may be shipped separately and may have separate tracking details.

7. Order Cancellations

You may request cancellation of any non-custom item, including a pre-order, at any time before that item ships. Once a non-custom item has shipped, it can no longer be cancelled, but an eligible return may be requested under our Refunds, Returns & Order Cancellation Policy.

Custom prescription lenses are subject to the separate terms in Section 8 and our Refunds, Returns & Order Cancellation Policy. If your order includes both custom lenses and separate non-custom items, you may request cancellation of the non-custom items before they ship.

8. Prescription Lenses and Custom Orders

Prescription lenses for LEION Hey 2 and LEION Hearing are made using the prescription and measurements you provide. Please check all values, including sphere (SPH), cylinder (CYL), axis, add power and pupillary distance (PD), before submitting your order. The processing estimate is shown on the relevant product page and in our Shipping Policy; prescription lenses usually require approximately 15 business days for processing and may ship separately from the glasses.

Once processing or fabrication of custom prescription lenses has begun, the custom lens item and any product sold as an inseparable package with it cannot be cancelled, returned, exchanged or refunded for a change of mind, a customer-entered prescription or measurement error, a later prescription change, personal fit or wearing comfort, or adaptation preference, except where LEION made an error or applicable law requires another remedy. If LEION makes the lenses to prescription details different from those you confirmed, or the lenses are defective or damaged due to an issue attributable to LEION, contact us so we can review and provide an appropriate correction, replacement or refund. These terms do not limit rights that cannot be excluded by law.

9. Returns and Refunds

Returns, refunds, exchanges and cancellation refunds are governed by our Refunds, Returns & Order Cancellation Policy. Eligible non-custom products may be returned by contacting us within 14 calendar days after delivery, subject to that policy and any mandatory rights that apply where you live. Custom prescription lenses follow the rules in Section 8 and the Refund Policy. Please contact us and wait for return instructions before sending a product back.

10. Warranty and Consumer Rights

LEION provides a limited commercial warranty of one (1) year for LEION Hey2 and two (2) years for LEION Hearing, beginning on the delivery date of the relevant product. During the applicable period, the warranty covers manufacturing defects under normal intended use and, for prescription lenses processed by LEION for that product, confirmed manufacturing or processing errors attributable to LEION. Customer-provided prescription or measurement errors, later prescription changes, personal fit, comfort or adaptation preferences, accidental damage, misuse and unauthorized repairs are not covered by this commercial warranty. Full coverage details and claim steps are in our Warranty Policy. Nothing in these Terms or the Warranty Policy limits a consumer guarantee, statutory remedy or other right that applicable law does not allow us to exclude or restrict.

11. Apps, Software and Digital Services

Some product features require a compatible mobile device, an internet connection, an account, third-party services or a paid plan or usage credits. Available features, language support, pricing, billing intervals, usage limits, expiry terms and cancellation instructions will be shown with the relevant product, plan or purchase. Any recurring subscription will be identified before you purchase it, including its renewal price and cancellation method.

We may update software or Services for security, compatibility, legal or operational reasons. We do not promise that every feature will be available at all times or in every language, location or device environment. These limitations do not remove any rights that apply to a paid digital service under local law.

12. Privacy

Our Privacy Policy explains how personal information is collected, used and shared. The Privacy Policy governs matters about personal information if it differs from these Terms.

13. Acceptable Use

You may use the Services only for lawful purposes. You must not misuse the Services, interfere with their security or operation, attempt unauthorized access, upload malicious code, infringe another person’s rights, submit false information, or use the Services to harass, defraud or harm others. We may suspend access where reasonably necessary to address a security risk, unlawful use or material breach, subject to applicable law.

14. Intellectual Property

The Services and their content—including LEION names and marks, text, graphics, images, videos, software and design—belong to LEION or our licensors and are protected by intellectual-property laws. You may use the Services for personal, non-commercial shopping and product use. You may not copy, distribute, modify, publish or commercially exploit our content without written permission, except where applicable law permits it.

15. Reviews and Feedback

You retain ownership of reviews, suggestions and other content you submit. You grant LEION a non-exclusive, worldwide, royalty-free license to host, reproduce and display that content as reasonably needed to operate, support and improve the Services. You confirm that you have the rights needed to submit it and that it is accurate to the best of your knowledge. We may remove content that is unlawful, deceptive, abusive, infringes rights or violates these Terms.

16. Third-Party Services and Shopify

The Services may link to or use third-party websites, payment providers, carriers, apps or tools. Those providers operate under their own terms and privacy practices. LEION is not responsible for third-party services that we do not control, except where applicable law provides otherwise.

Shopify provides the e-commerce platform that powers our storefront. Purchases from leion.glass are made directly with LEION; Shopify is not the seller of LEION products and does not handle LEION order fulfillment or customer support. Nothing in this section limits any right or remedy that cannot be excluded by law.

17. Errors and Changes

We may correct typographical, pricing, availability or product-description errors. If a material error affects an order you have placed, we will contact you and explain the available options, including cancellation and a refund where appropriate. We may update product listings, features or these Terms. Changes to these Terms take effect when posted, unless a later date is stated. Changes will not apply retroactively to an accepted order where applicable law prohibits that result.

18. Disclaimers

We provide the website and online features on an “as available” basis. We do not guarantee that the website or online Services will always be uninterrupted, secure or error-free. Product warranties, if any, are described in Section 10. To the extent permitted by law, we exclude implied warranties only where they may legally be excluded. Nothing in these Terms excludes a warranty, guarantee or remedy that applicable law makes mandatory.

19. Limitation of Liability

To the fullest extent permitted by applicable law, LEION will not be liable for indirect or consequential loss arising from use of the Services. Nothing in these Terms limits liability for death or personal injury caused by negligence, fraud or fraudulent misrepresentation, intentional misconduct, a breach that cannot legally be limited, or any consumer right or remedy that cannot be excluded under applicable law. Where liability may legally be limited, our liability for a claim relating to a product or order will not exceed the amount paid for the affected product or service, except where applicable law requires otherwise.

20. Indemnification

To the extent permitted by law, you agree to reimburse LEION for reasonable losses and costs arising from a third-party claim caused by your unlawful use of the Services, your infringement of another person’s rights, or your material breach of these Terms. This does not apply to the extent a claim was caused by LEION or cannot legally be shifted to you.

21. Suspension and Termination

You may stop using the Services at any time. We may suspend or terminate access where reasonably necessary for security, legal compliance or a material breach of these Terms. Ending access does not cancel any rights or obligations that arose before termination, including an accepted order, and does not affect provisions that by their nature continue to apply.

22. Governing Law and Disputes

These Terms are governed by the laws of Singapore, without preventing you from relying on mandatory consumer-protection laws that apply where you live. If you are a consumer, nothing in this section removes any right you may have under applicable law to bring a claim in the courts of your place of residence.

23. General Terms

If a court finds part of these Terms unenforceable, the rest will remain in effect, and the affected provision will apply to the maximum extent permitted by law. If we do not enforce a provision, that does not waive our right to enforce it later. These Terms and the policies linked above form the agreement between you and LEION about the Services, subject to any separate terms shown for a product, plan or promotion. You may not transfer your rights or obligations under these Terms without our consent. LEION may transfer its rights and obligations as part of a business reorganization or transfer, subject to applicable law. Section headings are for convenience only.
