Zero Trust Architecture
Our checkout experience is designed around the principle of zero trust. When you enter your card details, they are encrypted directly inside your browser before they ever leave your device.
- Military-grade AES-256-GCM encryption
- RSA-2048 key wrapping
- No raw card data traverses our network
Client-Side Envelope Encryption
We ensure a seamless, native checkout experience without redirecting you to third-party pages, while maintaining absolute security. Your sensitive data is locked before it even hits the internet.
Transient Processing
To securely route your payment to our PCI-certified gateway, our servers hold the decrypted data for less than a millisecond in volatile memory (RAM).
- Never written to disk or databases
- Never stored in server logs
- Memory is programmatically zeroed after use
Zero Data Persistence
We built our infrastructure so that sensitive cardholder data physically cannot be stolen from our databases, because it is never saved there in the first place.
DPO Pay
Payment Gateway Partner
All final card processing is handled by DPO Pay, one of Africa's largest PCI DSS Level 1 certified payment service providers, covering 54+ African countries.
Level 1 Processing
Once decrypted securely in-memory, the raw card data is immediately forwarded to our PCI DSS Level 1 partner for processing, ensuring compliance with global banking standards.
Clear Data Policies
We believe in complete transparency regarding the information we retain for accounting and support versus what we strictly discard.
What We Keep
Never Stored
