CardKeep : Card Wallet

CardKeep is a private, offline vault for your payment cards. Your card details live only on your device — encrypted by the hardware-backed secure storage of your phone. No servers, no accounts, no tracking. CardKeep never connects to the internet. TAP. COPY. PAY. Open a card, tap to copy the number or CVV, and paste it at checkout. The clipboard clears itself automatically after 45 seconds. WHY CARDKEEP? • 100% offline — your data never leaves your device • Encrypted with iOS Keychain, protected by Face ID / Touch ID • Optional app PIN for an extra layer of security • Beautiful, realistic card designs with embossed details • Wallet-style deck: flick through your cards like a real cardholder • Favorites always on top, drag & drop reordering • Auto-clearing clipboard — copied details vanish after 45 seconds • Expired-card badge, duplicate protection, Luhn validation • Dark and light themes • Available in 11 languages PRIVATE BY DESIGN We can't see your data. Nobody can. There are no analytics, no ads and no third-party SDKs. If you delete the app, your data is gone — that's the point. FREE & PRO Store up to 3 cards for free. A single one-time purchase unlocks unlimited cards — no subscription, ever. Note: CardKeep is a storage tool, not a payment app. It does not process payments and is not affiliated with any bank or card network.
