Distance Sales Agreement
Last updated: June 2026.
1. Parties
This Distance Sales Agreement (the "Agreement") is concluded between the following parties through a distance-selling channel without the simultaneous physical presence of the parties. SELLER: BRNVLY Yazılım Ticaret Anonim Şirketi (operating under the brand "Clastrum"), a joint-stock company (Anonim Şirket) incorporated in Türkiye under Turkish Commercial Code No. 6102. Registered office: Hasanpaşa Mah. Nabizade Sk. B Blok No: 82, Interior (İç Kapı) No: 1, Kadıköy / İstanbul, Türkiye. MERSİS: 0187176676500001 · Istanbul Trade Registry No: 1137479 · Tax No: 1871766765 (Kadıköy Tax Office). Contact: hello@clastrum.com · dpo@clastrum.com · +90 531 617 51 33 (hereinafter the "Seller"). BUYER: The natural or legal person who orders and pays for the Seller's services through this site and approves this Agreement at the time of order; the Buyer's identity, address, and contact details are those provided by the Buyer during the order process (hereinafter the "Buyer"). By approving this Agreement, the Buyer confirms that they have read and understood the essential characteristics, total price, payment, and performance terms of the services that are the subject of this Agreement, and have given the necessary confirmation electronically.
2. Subject of the Agreement
The subject of this Agreement is the determination of the rights and obligations of the parties, in accordance with Law No. 6502 on the Protection of the Consumer and the Regulation on Distance Contracts (Mesafeli Sözleşmeler Yönetmeliği), with respect to the sale and delivery of the professional services ordered by the Buyer electronically from the Seller and the price of which is specified below. The Seller provides professional intelligence, data, and engineering consulting services; it does not sell physical goods. No physical product is shipped under this Agreement.
3. Description and price of the service
The Seller delivers fixed-scope, fixed-price professional engagements in two forms. "Forge" is an end-to-end build that lives in production: a fixed scope delivered for a fixed price over a typical period of 6 to 16 weeks. "Lens" is a senior diagnostic delivered as a written report over a typical period of approximately 2 weeks. The exact scope, deliverables, acceptance criteria, timeline, and total price of each engagement are agreed in writing on a per-engagement basis in a Statement of Work (SoW) confirmed by both parties before work begins, and are presented to the Buyer prior to payment. The price displayed at the order step is the total amount payable by the Buyer, including all taxes. All prices are subject to Value Added Tax (KDV) at the rate applicable under Turkish law at the date of invoice, which is shown separately on the invoice. The agreed price does not include any third-party costs (e.g. cloud infrastructure, licences) unless expressly stated in the Statement of Work.
4. Payment
Payment is collected online through the iyzico payment gateway by credit card, debit card, or other payment methods supported by iyzico. The Seller does not store full card details; card data is processed by iyzico under PCI-DSS standards. Payment may be taken as a single amount or in agreed instalments (e.g. an initial payment to commence and a balance on delivery), as set out in the applicable Statement of Work and presented at the order step. The Buyer confirms that the payment instrument used belongs to the Buyer or is used with the cardholder's authorisation. If the payment is not completed, declined, or charged back, the Seller is entitled to suspend or not commence performance until valid payment is received. An invoice is issued and sent electronically to the Buyer following successful payment.
5. Service delivery
The services are professional and digital in nature and are performed and delivered electronically (e.g. via online sessions, repositories, deployed software, and written reports). No physical shipment takes place and, accordingly, no delivery or cargo cost arises. Performance begins after the order is confirmed and payment is received, on the start date agreed in the Statement of Work, and continues over the engagement timeline stated in Article 3 (typically 6–16 weeks for Forge and approximately 2 weeks for Lens). Where the Buyer fails to provide access, information, or approvals reasonably required for performance, the corresponding timelines are extended accordingly. Deliverables and reports are made available to the Buyer through electronic means (download, repository access, or email).
6. Right of withdrawal (Right of Cancellation / Cayma Hakkı)
Where the Buyer is a consumer, the Buyer has the right to withdraw from this Agreement within fourteen (14) days without giving any reason and without incurring any penalty. To exercise this right, the Buyer must notify the Seller in writing within the period by email to hello@clastrum.com, stating the order and the intention to withdraw. STATUTORY EXCEPTION: Pursuant to Article 15 of the Regulation on Distance Contracts, the right of withdrawal does not apply to services where performance has begun with the consumer's express consent before the end of the withdrawal period, nor to services performed instantly in electronic form. By approving this Agreement and requesting that the engagement commence before the expiry of the 14-day period, the Buyer expressly consents to the commencement of performance and acknowledges that the right of withdrawal is thereby lost once performance has begun. If performance has not yet begun, the Buyer may exercise the right of withdrawal within the said period and any amount paid is refunded to the same payment instrument within fourteen (14) days of the Seller's receipt of the withdrawal notice.
7. Default and obligations of the parties
The Seller undertakes to perform the agreed services with the care expected of a professional, in accordance with the Statement of Work, and to deliver the agreed deliverables within the agreed timeline. The Buyer undertakes to make payment in full, to provide in a timely manner the access, materials, information, and approvals reasonably required for performance, and to use the deliverables in accordance with the agreed terms. If the Buyer defaults in payment, the Seller may, in accordance with applicable law, suspend performance and claim default interest and its losses. If the Seller fails to perform its obligations, the Buyer may exercise its statutory rights under Law No. 6502. Each party is responsible for the confidentiality of the other party's information disclosed in connection with the engagement.
8. Dispute resolution
For disputes arising from this Agreement, the Buyer may, up to the monetary limits announced annually by the Ministry of Trade, apply to the District/Provincial Consumer Arbitration Committees (Tüketici Hakem Heyetleri) at the Buyer's or the Seller's place of residence, and above those limits to the Consumer Courts (Tüketici Mahkemeleri). Where no Consumer Court exists, the Civil Courts of Peace act in that capacity. This Agreement is governed by the laws of the Republic of Türkiye.
9. Effective date and acceptance
This Agreement enters into force on the date the Buyer approves it electronically at the order step and completes payment, and is concluded for the duration of the engagement. The Buyer is deemed to have accepted all terms of this Agreement by placing the order and completing payment. A copy of this Agreement is provided to the Buyer in durable form and is also available at this address.
