This English translation is provided for convenience. The Turkish version is the binding text.

In accordance with Law No. 6502 on Consumer Protection and the Distance Contracts Regulation, please read the following information before making a payment.

1. Seller

2. Nature of the service

Blorp is a free engineering calculation and learning tool. All tools are open to everyone free of charge; making a payment does not unlock any feature. A payment made on this site is a voluntary support payment that the user makes of their own accord and in an amount they choose themselves (digital service). No physical product is sent in return.

3. Price and payment

The buyer chooses the amount on the payment page; taxes are included. Payment is taken by credit or debit card through the licensed payment institution iyzico (İyzi Ödeme ve Elektronik Para Hizmetleri A.Ş.). Card details are not passed on to the seller and are not stored by the seller. There is no additional delivery or shipping fee.

4. Performance

The support payment takes effect immediately upon confirmation of the payment. The invoice (e-Arşiv) for the payment is sent to the e-mail address given by the buyer.

5. Right of withdrawal and refund

Since the service is performed instantly in electronic form, there is no statutory right of withdrawal under Article 15 of the Distance Contracts Regulation. Nevertheless, the seller accepts, without asking for a reason, refund requests sent to info@tolya.com.tr within 14 days of the payment date (see Cancellation and refund).

6. Complaints and objections

You can send your complaints to info@tolya.com.tr. In disputes, the Consumer Arbitration Committees and Consumer Courts at the consumer's place of residence or where the transaction was made have jurisdiction, within the monetary limits announced each year by the Ministry of Trade.
