Refund and Right of Withdrawal Policy

This Policy applies to purchases made on the Mayza platform provided by Abdullah Yiğit Sağlam ("I"). Your purchases are also subject to the Terms of Use and the Distance Sales Agreement.

1. The Exception to the Right of Withdrawal, Read This First

Mayza Premium is a digital service activated on your account immediately after payment. Under Article 15/1-ğ of the Turkish Regulation on Distance Contracts, the right of withdrawal cannot be exercised for contracts covering services performed instantaneously in an electronic environment.

For this reason, at the purchase step you are asked to confirm that you expressly request performance to begin immediately and that you accept losing your right of withdrawal once performance is complete. The purchase cannot be completed without this confirmation. See the Preliminary Information Form for details.

The absence of a right of withdrawal does not affect your statutory rights or refund requests in cases of defective service, access problems, or incorrect charges, as described below.

2. When I Do Issue Refunds

Despite the withdrawal exception, I will review your request and provide a refund or an extension where it is justified, in the following cases:

• Inability to access the service: If you could not use Premium because of a fault attributable to me that was not resolved within a reasonable time.
• Defective service: If the service does not meet its published essential characteristics.
• Incorrect or duplicate charges: If you were charged more than once for the same period, or a payment was taken without your authorisation.
• Access never granted: If your payment was taken but Premium access was never enabled (I will enable it first; a refund is available if you prefer).

No time limit applies to these requests, simply write to me when you notice the problem.

3. Payment Channel and Seller Capacity

Payments are taken through iyzico, an authorised payment and electronic money institution. On this channel I am the seller directly; iyzico is only the payment service provider, and refund requests come to me.

4. Auto-Renewing Subscription and Cancellation

Premium access renews automatically for the period you choose (monthly or yearly) until you cancel. You can cancel at any time from the membership page of your Mayza account; cancellation takes effect at the end of the current period, and your Premium access continues until then. No partial refund is given for the current, already-paid period, subject to the right-of-withdrawal exception above; no charge is taken for the following period.

5. How to Submit a Refund Request

You can reach me in the following ways:

• Directly: Write to info@lumiverion.com from the e-mail address you used to purchase, or call the number on the Contact page.

Quoting your order/payment reference or purchase date speeds things up. Requests are resolved within 14 days at the latest.

6. Refund Timing and Method

Approved refunds are made to the original payment method and in the original currency. Depending on your bank, the amount usually reaches your account within 3–10 business days.

I am not responsible for differences in amount arising from exchange rate fluctuations.

7. Access After a Refund

When a refund is issued, Premium access for the refunded period ends and your account returns to the free tier. Your exam history and progress records are not deleted.

8. Exceptions

I reserve the right to decline a refund request where abuse is identified (for example repeated purchase–refund cycles, unauthorised use of a payment instrument, account sharing, or breach of the Terms of Use). In such cases I will notify you of the reason in writing.

9. Contact and Complaints

For questions about these refund terms: info@lumiverion.com. If your request cannot be resolved, you may apply to the Consumer Arbitration Committee or the Consumer Court at your place of residence, within the monetary thresholds announced by the Ministry of Trade.
