A private vault for your card details. Everything is encrypted, stored on your phone and locked behind your PIN, with fingerprint or face unlock if you turn it on. Kuber never sends card data over any network.

  • Payment Cards of Every Kind: Debit, credit, prepaid, forex, gift, travel, fuel, meal and corporate cards, on Visa, Mastercard, RuPay, American Express, Discover and more.
  • Encrypted Fields: The card number, cardholder name, expiry and any custom fields are stored only as encrypted data (AES-GCM, 256-bit). The list shows just the nickname and the last 4 digits.
  • Your PIN Holds the Key: The encryption key is derived from your PIN and never stored as is. Biometric unlock keeps the key in your phone’s hardware-backed Keystore.

The free plan holds 2 cards. Kuber Pro removes the limit.
