1. Accepted Payment Methods

The payment methods currently available for your order will be displayed during checkout.

Available options may vary depending on your location, currency, device, and the payment services available on our website.

Please review the payment options shown at checkout before completing your purchase.

2. Payment Authorization

When you place an order, your payment provider may authorize or process the transaction before your order is confirmed.

Your order may not be considered complete until payment has been successfully authorized or confirmed.

In some cases, your bank or payment provider may temporarily place an authorization hold on your account while the transaction is being reviewed.

3. Secure Payment Processing

Payments made through our website are processed using the payment services made available through our checkout system.

Depending on the payment method selected, your transaction may be processed by third-party payment providers, financial institutions, card networks, or other authorized service providers.

We generally do not need to directly store your complete payment card details when those details are securely handled by an authorized payment processor.

4. Website Security

We use reasonable technical and organizational measures designed to help protect information transmitted through our website.

Secure website connections and payment technologies may be used to help protect sensitive information during checkout.

However, no internet transmission or electronic system can be guaranteed to be completely secure.

5. Billing Information

When placing an order, please make sure that your billing information is complete and accurate.

Incorrect billing information may cause your payment to be declined, delayed, or flagged for additional verification.

Depending on your payment provider, the billing address may need to match the information associated with your payment method.

6. Payment Verification

For security and fraud-prevention purposes, some transactions may require additional verification before an order is processed.

This may include verification by your bank, card issuer, payment provider, or our checkout system.

In some circumstances, we may contact you for additional information reasonably necessary to review an order.

7. Why Was My Payment Declined?

A payment may be declined for a variety of reasons, including:

• Incorrect card or payment information
• Incorrect billing address
• Insufficient funds or available credit
• Bank or card issuer restrictions
• International transaction restrictions
• Security or fraud-prevention checks
• An expired or inactive payment method
• Technical issues with the payment provider

If your payment is declined, please verify your information and try again. If the issue continues, contact your bank or payment provider for assistance.

8. Pending Charges and Authorization Holds

You may occasionally see a pending charge or temporary authorization on your account even if an order was not successfully completed.

These temporary holds are generally controlled by your bank or payment provider and may be released automatically according to their procedures.

If you are unsure whether an order was successfully placed, please check for an order confirmation email or contact our customer service team.

9. Duplicate Charges

If you believe you have been charged more than once for the same order, please first review your bank or payment account to determine whether one of the transactions is still pending.

A pending authorization may sometimes appear alongside a completed charge and may disappear automatically.

If you believe you were actually charged twice, please contact us with your order number and relevant transaction details so we can review the issue.

10. Currency and Conversion

Prices and transaction currencies may vary depending on the settings available on our website and checkout.

If your bank or payment provider converts the transaction into another currency, exchange rates or foreign transaction fees may be determined by that provider.

SERENLO™ does not control fees or exchange rates imposed by your bank, card issuer, or other payment provider.

11. Taxes and Additional Charges

Applicable taxes, duties, fees, or other charges may be calculated during checkout or imposed according to the destination and applicable law.

Charges imposed directly by your bank, card issuer, payment provider, or local authority are generally outside our control.

12. Refunds to Your Payment Method

If a refund is approved, it will generally be issued to the original payment method used for the purchase unless another method is required or agreed upon.

After we process a refund, your bank or payment provider may require additional time before the funds appear in your account.

For more information about refund eligibility, please refer to our Return & Refund Policy.

13. Fraud Prevention

To protect customers and our business, transactions may be reviewed for suspected fraud, unauthorized activity, or other security concerns.

We reserve the right to delay, cancel, or request verification for an order where reasonably necessary to protect against unauthorized or fraudulent activity.

14. Protecting Yourself Online

We recommend that customers take reasonable precautions when shopping online.

• Make purchases only through the official SERENLO™ website
• Do not share passwords or verification codes with unknown parties
• Check the website address before entering payment information
• Use secure devices and trusted internet connections where possible
• Contact us if you receive suspicious messages claiming to represent SERENLO™

15. Payment Disputes

If you have a concern about a payment, refund, or order, please contact our customer service team so that we can review the matter.

If a payment dispute or chargeback is opened through a financial institution or payment provider, we may provide relevant order, payment, shipping, tracking, and communication records when responding to that dispute.

16. Third-Party Payment Providers

Payment services may be provided by independent third-party providers. Their handling of payment information may be subject to their own terms, privacy policies, security procedures, and service rules.

We encourage customers to review the applicable payment provider's terms where appropriate.
