3.1. All taxes are included; there are no other costs.
3.2. Payment is made by credit or debit card on the secure payment page of a payment institution licensed under Law No. 6493. Card details are not transmitted to or stored by Diyaval. If the payment institution or bank does not approve the payment, no agreement is concluded.
3.3. An e-invoice or e-archive invoice is issued within 7 days of payment confirmation and sent to the Buyer's email address.
Article 4 – Performance
4.1. Diyaval activates the modules in the Buyer's Diyaval company account within 3 business days of payment confirmation. If there is no account, Diyaval creates one in the same period and emails the sign-in details. The activation date is the performance date and is notified to the Buyer by email.
4.2. If Diyaval cannot meet this period it notifies the Buyer before the period ends. A consumer Buyer may terminate the agreement if performance is not made on time; the amount paid is refunded within 14 days.
4.3. Onboarding and training hours are delivered by video call on dates agreed by the parties and must be used within 12 months of the order date. Unused hours lapse at the end of that period; for a consumer Buyer, unused hours are refunded.
Article 5 – Term and renewal
5.1. Modules licensed for a one-time fee may be used without a time limit for as long as the Platform Foundation usage term is active.
5.2. Annual use items are valid for 12 months from activation. All of the Buyer's annual items share a single renewal date. Annual items added during the year are priced pro rata for the remaining days and aligned to that date.
5.3. Annual items do not renew automatically and no automatic card charge is made. At least 30 days before the renewal date, Diyaval emails the renewal fee and a payment link. If the Buyer pays, the term is extended by 12 months.
5.4. If the renewal fee is not paid, the relevant items close at the end of the term and the Buyer's data remains available read-only for 90 days, during which the Buyer may export it or renew and continue. After that period the data is deleted, subject to statutory retention obligations.
5.5. The renewal fee is the amount shown in the notice. If the Buyer does not accept it, the Buyer simply does not renew and has no further obligation.
Article 6 – Withdrawal and cancellation
6.1. A consumer Buyer has a 14-day right of withdrawal from conclusion of the agreement. Under Article 15(ğ) and (h) of the Distance Contracts Regulation, this right does not apply to services performed instantly in electronic form and to services whose performance begins with the consumer's approval within the withdrawal period. The Buyer separately approved such performance when ordering; the right of withdrawal therefore ends when the modules are activated.
6.2. If a withdrawal notice or (for a merchant Buyer) a cancellation request reaches Diyaval before activation, the full amount is refunded to the card used within 14 days of receipt. Notices are sent by email to [email protected], by KEP to — or in writing to Selçuk University Technology Development Zone No: 67, Selçuklu, Konya, Türkiye.

For a merchant Buyer, use continues until the end of the term and annual fees are not refunded. Termination may also be notified by the method used to conclude the agreement (email) and is processed within 7 days.
