The ultimate offline-only card vault for Android. Military-grade AES-256 encryption, zero data collection, and absolutely no cloud syncing.
We believe the safest place for your data is right in your pocket. CardyWall has no servers, no API calls, and no way to transmit your card details. It's an air-gapped vault app.
Your database is locked with AES-256 encryption standards. Even if someone steals your file, it's mathematically impossible to crack without your unique key.
More than just a vault. CardyWall instantly identifies card types and banks using on-device BIN lookups. Scan a card with OCR and let the app handle the rest.
Absolutely not. CardyWall is an offline-first "vault" application. It has zero internet permissions for sending data. Your cards never leave your device.
Float Mode allows CardyWall to hover over other apps (like Chrome or Amazon). This lets you view your card details while you type them in, without switching apps back and forth.
Since we don't use cloud sync, data transfer is manual. We are currently building an encrypted export/import feature to let you safely move data between devices.
CardyWall is free to use. We may introduce optional premium themes in the future, but the core security features will always remain free.
We built CardyWall because we were tired of "free" apps stealing data. We promise: No tracking pixels. No analytics. No third-party SDKs. What you store in CardyWall stays in CardyWall.
