Refund Policy

This Refund Policy applies to all paid services operated by Elicova (the "Company") under the Mathiter brand. It complies with Korea's Act on Consumer Protection in Electronic Commerce and applies together with the Company's Terms of Service.

This policy covers the Mathiter learning app subscription. Mathiter Tutoring is offered in the Republic of Korea only; its refund rules are in the Korean-language Refund Policy. If you are unsure which track applies to you, please contact support@mathiter.com.

The Mathiter learning app (SaaS) follows the principles of Korea's Act on Consumer Protection in Electronic Commerce and standard digital content terms.

Refund Conditions:

Refund processing: Refunds are processed within 7 business days back to the original payment method (card). Cash receipts and tax invoices issued automatically by Toss Payments are also cancelled automatically. If the payment method has expired, an alternative refund (bank transfer) will be arranged with the customer.

Subscribers may cancel at any time, immediately, via My Page. The Company does not require separate contact and does not delay the process. Automatic charges stop from the next billing period.

[Monthly subscription]

• Paid features remain accessible through the end of the one-month period already paid for.
• Cancelling mid-period does not produce a pro-rated refund for that month, because the billing unit is a single month and the service for it has already been supplied.
• However, if the Member has never accessed a paid feature within 7 days of payment, a full refund applies under A-3.

[Annual subscription] — pro-rata refund on mid-term cancellation

An annual subscription pays twelve months in advance, so on mid-term cancellation the Company settles the period already used and refunds the remainder. As a continuing transaction under the Act on Door-to-Door Sales, the Member may terminate at any time and the Company does not deduct amounts materially exceeding its actual loss.

Refund = amount paid − (undiscounted monthly price × months used)

• Months used runs from the payment date to the cancellation date; any month begun counts as one full month.
• Settlement uses the undiscounted monthly price, since the annual discount is granted in return for a twelve-month commitment.
• If the result is zero or less, no refund is due.
• Where cancellation is caused by the Company (permanent discontinuation, service materially different from what was advertised, and the like), the remaining period is refunded in full on a daily pro-rata basis without the above deduction.

Amounts are calculated from the prices shown on the pricing page.

The Mathiter learning app provides all digital content (lessons, problems, AI coaching) to the Member immediately upon payment. Under Article 17(2)(5) of Korea's Act on Consumer Protection in Electronic Commerce, the right of withdrawal may be limited for digital content that can be used immediately.

However, refunds are available in the following cases:

• Payment without use: Full refund if the Member has never accessed any paid feature within 7 days of payment.
• Company's responsibility: Pro-rated refund for days the Service was unavailable due to system fault for more than 24 hours.
• Service materially different from advertisement: Full refund if the actual service differs significantly from displayed/advertised content.

If a system error causes duplicate charges for the same Member or incorrect failure handling, the Company detects and automatically refunds to the original payment method within 7 business days.

To request a refund, contact us through one of the following:

• Email: support@mathiter.com — Include registered email, payment date/time, and refund reason.

The Company processes refunds within 7 business days of request receipt. Depending on the payment processor (Toss Payments) and card issuer policies, the actual card cancellation or bank deposit may take an additional 3–7 business days.

If the registered payment method has expired or is otherwise unusable, the Company coordinates with the Member for an alternative refund method such as bank transfer.

If you have any issue with refund processing, please first contact our customer support at support@mathiter.com. The Company will respond promptly.
