| Price | Prices for each plan are shown on the Pricing page. Where consumption tax or other taxes apply under applicable law, the total amount payable including tax is shown on the order screen. The amount shown on the order screen is the amount you pay. |
| Additional charges | Internet connection fees, communication charges, and other costs required to use the Service are your responsibility. PayPal or your card issuer may also charge its own fees (such as foreign transaction fees or currency conversion fees). |
| Payment methods | PayPal (credit cards, etc.). Payments are charged in Japanese yen (JPY) or US dollars (USD), and the billing currency is shown on the checkout screen. The payment methods available to you are shown on the PayPal checkout screen. PayPal payment is not offered in the Republic of Korea. |
| Payment timing | First payment: at the time you subscribe (when you approve automatic payments in PayPal). Subsequent payments: charged through PayPal automatic payments on the renewal date of each term. The date your card is debited depends on your card issuer. |
| Service delivery | You can use the Service immediately after your payment is confirmed. |
| Contract term and automatic renewal | Monthly plans have a one-month term and annual plans have a one-year term, and both are billed on a recurring basis. When you subscribe, you approve automatic payments to us in PayPal. Unless you cancel, your subscription automatically renews for the same plan and term when each term ends. The renewal amount is shown on the Pricing page and the order screen. If a discount applies, the number of billing periods it applies to and the amount payable after the discount ends are shown when you subscribe. If the amount payable changes, for example because a discount ends, we will notify you at least 10 days before the new amount is first charged. |
| Plan changes and price changes | You cannot switch directly to a different plan or billing cycle (monthly or annual) during a term. To change, please cancel your current subscription and then subscribe again to the plan you want. You can continue to use the cancelled subscription until the end of the current term, and there is no prorated refund or settlement of the difference for the remaining period. A new subscription can be started after the cancelled subscription ends. If we change our prices, we will notify you at least 30 days before the change takes effect, and the new price will apply from your first renewal on or after the effective date. |
| How to cancel | You can cancel online at any time. If you complete cancellation before your next renewal date, you will not be charged for any subsequent term. After you cancel, you can continue to use the Service until the end of your current term. You can cancel from the subscription management menu on your account page in the Service, or from the automatic payments settings in your PayPal account (by cancelling your automatic payments to us). If you cancel your automatic payments in PayPal, you will not be charged for any subsequent term either, and you can continue to use paid features until the end of the term you have already paid for. |
| Returns, cancellations, and refunds | If you request a refund within 14 days of your first subscription payment (once per account), or within 14 days of the renewal date for an annual plan renewal, we will refund the payment in full regardless of whether you have used the Service (once the refund is completed, the subscription ends immediately and you will no longer have access to paid features). Monthly plan renewal charges are generally not eligible for a refund, except where a refund is made under applicable law, and you can cancel at any time before your next renewal date. We do not provide prorated refunds when you cancel. For duplicate payments and billing errors, we will refund the amount charged in error regardless of when they occurred, and your subscription will continue. For payments you did not make yourself, we will refund them regardless of when they occurred, and any subscription started or renewed by such a payment ends immediately and you will no longer have access to paid features. Please send refund requests to us at global@ohsungsys.com. We issue refunds through PayPal to your original payment method. For details, see our Refund Policy. |
