Website purpose

This website provides information about Sadatech and its products. Product descriptions, pricing, and conceptual previews may change as the products evolve.

Payments and third-party processing

Serahin supports pre-order payments, while Manifly offers monthly software memberships. Automatic checkout is created through Sadatech's payment service and completed on a third-party provider's hosted page. Sadatech does not ask for or store full card numbers, PINs, internet-banking passwords, or OTPs. The product shows applicable checkout availability, methods, amount, fees, and payment recipient before confirmation. Sadatech is not a bank, e-wallet, or payment-gateway provider. See How payments work and the Refund policy.
