Commercial Information

Product Prices

Product prices are displayed on the applicable product pages.

Prices may be displayed in different currencies depending on the customer’s location or selected currency. The final amount charged will be shown at checkout before the order is submitted.

Currency-conversion rates displayed on the website may be provided by third-party payment or e-commerce service providers and may differ from the rate applied by the customer’s bank, card issuer, or payment provider.

Additional Charges

Customers may be responsible for charges in addition to the displayed product price, including:

• Shipping fees

• Customs duties

• Import taxes

• Value-added tax

• Brokerage or customs-clearance charges

• Foreign-currency conversion charges

• Charges imposed by banks, card issuers, or payment providers

The shipping fee charged by DYNACY will be displayed at checkout before payment is completed.

International duties, taxes, and import-related charges may be imposed separately by the destination country or region unless expressly stated otherwise at checkout.

Payment Methods

Available payment methods will be displayed at checkout.

Payment is generally required in full when an order is submitted. An order is not confirmed until payment has been successfully authorized and an order-confirmation notice has been issued.

Payment processing may be provided by independent third-party payment providers. DYNACY does not directly receive or store complete payment-card numbers where payments are processed through those providers.

Order Processing and Delivery

Orders are generally processed within 3–7 business days after successful payment.

Business days do not include weekends or Japanese public holidays.

Orders are generally fulfilled and shipped from Japan. Estimated delivery periods, available shipping services, tracking availability, fees, and shipping restrictions are explained in our Shipping Policy.

Processing and delivery estimates are provided for reference only and are not guaranteed.

Returns and Cancellations

Return, exchange, cancellation, and refund conditions are described in our Return and Refund Policy.

Because oral mouthpieces are personal and hygiene-sensitive products, products that have been unsealed, fitted, moulded, adjusted, placed in the mouth, cleaned, worn, or otherwise used may not be eligible for return.

This restriction does not apply where a return or remedy is required under applicable consumer law, or where the product is confirmed to be defective, damaged upon delivery, or incorrect.

Nothing in this Legal Notice excludes any mandatory right or legal remedy that cannot lawfully be excluded.

Product Information

DYNACY offers nighttime mouthpieces and related sleep-wellness products.

Product descriptions, materials, dimensions, fitting methods, adjustment instructions, suitability information, cleaning instructions, warnings, and limitations may vary by product.

Customers must carefully review the applicable product page, packaging, instructions, and safety information before purchasing or using a product.

Images, illustrations, diagrams, and videos are provided for general presentation or instructional purposes. Minor differences in colour, texture, measurements, packaging, components, or appearance may occur because of:

• Screen and display settings

• Manufacturing tolerances

• Product improvements

• Packaging updates

• Different production batches

DYNACY does not guarantee that every product will be suitable, comfortable, or effective for every individual.

Health and Medical Disclaimer

Information provided on this website is for general product-information and educational purposes only. It does not constitute medical, dental, diagnostic, or other professional healthcare advice.

Unless expressly supported by the product’s applicable regulatory authorization and clearly stated on the relevant product page, DYNACY products are not intended to diagnose, treat, cure, mitigate, or prevent:

• Obstructive sleep apnea

• Central sleep apnea

• Respiratory disorders

• Temporomandibular joint disorders

• Dental conditions

• Any other disease or medical condition

DYNACY products are not replacements for CPAP therapy, prescribed medical equipment, professionally fitted dental appliances, medication, surgery, or any treatment recommended by a qualified healthcare provider.

Snoring may sometimes be associated with an underlying health condition. Customers should consult a qualified doctor, dentist, or sleep specialist before using a nighttime mouthpiece if they:

• Have diagnosed or suspected sleep apnea

• Experience interrupted breathing, choking, or gasping during sleep

• Experience severe or persistent daytime sleepiness

• Have loose teeth, gum disease, jaw pain, or significant dental conditions

• Wear braces, retainers, dentures, implants, crowns, or bridges

• Have recently undergone dental or oral surgery

• Have difficulty breathing through the nose

• Are uncertain whether the product is appropriate for them

Customers must follow all fitting, adjustment, cleaning, storage, and safety instructions supplied with the product.

Use must be discontinued if the product causes persistent pain, significant jaw discomfort, bleeding, loose teeth, changes to the bite, an allergic reaction, breathing difficulty, or any other concerning symptom.

Individual experiences and results vary. Customer testimonials, reviews, examples, and descriptions do not guarantee that another customer will experience the same result.

Age Restriction

Unless expressly stated otherwise on the applicable product page, DYNACY nighttime mouthpieces are intended only for adults aged 18 years or older.

Products, packaging, storage cases, adjustment tools, and small components must be kept away from children and pets.

No Professional Relationship

Accessing this website, purchasing a product, contacting customer support, or receiving general product guidance does not create a doctor-patient, dentist-patient, healthcare-provider, fiduciary, or other professional relationship between the customer and DYNACY Limited Liability Company.

Customer-support representatives cannot diagnose medical or dental conditions or determine whether a product is medically appropriate for a particular customer.

Website Information

DYNACY makes reasonable efforts to maintain accurate and current website information. However, information may occasionally contain:

• Typographical errors

• Technical inaccuracies

• Incomplete descriptions

• Incorrect prices

• Outdated availability information

We may correct errors and update product information, prices, availability, packaging, policies, or website content where reasonably necessary.

Where an obvious pricing or product-information error affects an order, we may contact the customer to provide the correct information and, where permitted by applicable law, offer the customer the option to confirm or cancel the affected order.

Product Availability

All products are subject to availability.

Placing an item in a shopping cart does not reserve inventory. We may limit quantities, discontinue products, decline orders, or cancel an order where reasonably necessary because of:

• Stock or inventory errors

• Legal or regulatory restrictions

• Product-safety concerns

• Shipping limitations

• Obvious website or pricing errors

Where an order is cancelled after payment has been collected, the applicable payment will be refunded using the original payment method, subject to payment-provider processing times.
