Secure Knowledge

🔐 How secure is the offline encryption?

Every piece of data is encrypted using AES-256-GCM before it hits your disk. The keys are managed by your device's Secure KeyStore/TEE, ensuring even a rooted device has a hard time accessing your vault.

💾 What happens if I lose my phone?

Because we never touch your data, we cannot recover it for you. We highly recommend using the built-in encrypted backup feature to store your vault on a secure external drive or private storage.

🤳 Is biometric auth mandatory?

While not mandatory, it is highly recommended. CardyWall integrates with iOS FaceID and Android Strong Biometrics to provide a L3 security layer that is hardware-locked to your physical person.

📶 How does NFC Quick-Add stay private?

The NFC scanning logic is processed entirely in a sandboxed, hardware-isolated memory space. No data from your scanned cards is ever sent to any network; it is decrypted, parsed, and encrypted into your local vault in one atomic operation.

🔍 Does the app collect any telemetry?

None. Zero. We do not use Firebase Analytics, Mixpanel, or even basic crash reporting that sends data. CardyWall is a "Silent Guardian" that functions entirely within your device's ecosystem.
