Download the APKMost business card apps are a front end for someone else's server. Your contacts become their asset, and the features you need sit behind a monthly fee.

Built for the person who comes home from a conference with forty cards in a jacket pocket.
Frame the card in the camera and tap once. Turn on batch mode first if you have a stack of them.
Text recognition runs on the phone and fills the fields in. Fix anything it misread, pick a category, add notes.
The card lands in a local SQLite database — searchable, filterable, and exportable to Excel or CSV at any time.
Plenty of apps promise not to misuse your contacts. CardVault is built so that it cannot: card images are processed by a recognition model bundled into the app, and the results are written to a SQLite database in the app's own private storage. There is no CardVault server for that data to be sent to.
That matters more than it sounds. A business card is somebody else's personal data — their name, direct line, and work email — handed to you in confidence. Uploading a stack of them to a third-party service is a decision you are making on their behalf. With CardVault there is no such decision to make.
The trade-off, stated plainly: nothing syncs. If you lose the phone without a backup, the cards are gone. Use the backup feature, and keep the file somewhere you trust.
CardVault is distributed here as a direct APK download, so Android will ask you to approve it.
