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.

Notice: The recurring subscription (auto-renewal) refund policy below applies to a product that has not been released yet. It will take effect when the recurring subscription product is launched, with a separate announcement.

Paid subscribers may cancel anytime via My Page. The following applies at cancellation:

• Auto-renewal stops immediately: No further automatic charges occur in subsequent billing periods.
• Access continues until end of current period: Paid features remain accessible through the end of the already-paid month.
• No pro-rated refunds: Mid-period cancellations do not trigger a refund for unused days.

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.
• KakaoTalk Channel: @mathiter — Click to open a 1:1 chat instantly.
• My Page: "Payment history → Request refund" menu (planned).

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.

If resolution is not reached, Members may request mediation through:

• Korea Consumer Agency (consumer.go.kr, 1372)
• E-Commerce Dispute Mediation Committee (ecmc.or.kr)
• The court of first instance having jurisdiction over the Company's business address

The Company may update this Refund Policy from time to time. Material changes will be announced via in-Service notice and email to registered Members at least 7 days in advance (or at least 30 days in advance for changes adverse to Members).
