In supported apps and websites, choose a card and authenticate before its details are filled. Some forms do not support autofill; use copy and paste instead. Card data is encrypted using Android Keystore-backed storage. • Scan card numbers, expiry dates and cardholder names with on-device camera recognition. Review the suggestions before saving; enter the CVV yourself. • Search cards, choose card colors, mark favorites and drag cards into your preferred order. • Use biometric or device authentication, with an optional app PIN. The wallet locks again after time in the background. • Copy card details with one tap. Copied details expire automatically after 45 seconds. • Choose dark or light mode and one of 11 languages. OPTIONAL ENCRYPTED BACKUPS Export a password-encrypted backup to a location you choose and import it later. Keep the backup password safe: it is required to open the file. Existing cards are kept and duplicate card numbers are skipped during import. PRIVATE BY DESIGN Card data is encrypted on your device. Camera recognition runs on-device. CardKeep does not operate a card-storage server and has no advertising or analytics. If you export a backup, a password-encrypted file is saved to your selected location. FREE & PRO Store up to 3 cards for free. A one-time Pro purchase unlocks unlimited cards. No subscription. CardKeep stores card details; it does not process payments and is not affiliated with a bank or card network.
