Privacy

This page describes the new native, device-local Kertas Cards release. It does not describe the older account-based CardKeeper web service.

How the app handles your library

The app stores card images, recognized contact details, notes and follow-ups in its local library. The primary release requires no app account and does not upload the library to an app-operated server. Apple Vision recognizes text locally on iOS; bundled Google ML Kit models recognize text locally on Android. You review the results before saving.

Platform and recognition services

The native app does not add advertising, cross-app tracking or an app-operated analytics or crash-reporting service. iOS uses Apple Vision and does not include Google ML Kit.

Android includes bundled Google ML Kit text recognition. Google documents technical diagnostics and usage information, including device/app details, per-installation identifiers, performance, image configuration and sizes, feature events and error codes. Google uses this metadata to operate, debug, improve and protect its APIs and documents HTTPS transmission. Google states that input images/text and recognition results are processed on device and are not sent to its servers. See ML Kit terms and privacy and its data-disclosure guidance.

This Android release has no Internet permission. That restricts the app's network access; it is not a claim that separately running Google services, the operating system or providers you choose never communicate.

Backups and providers you choose

You can export a passphrase-encrypted archive containing your local cards, images, notes, follow-ups and deletion records. Earlier account-owned records remain separate and are excluded from these local-library backups. You choose the destination through Files or the Android document picker. A cloud or document provider you select operates under your account, settings and that provider's privacy terms.

The app has no backup-passphrase recovery service. Exported copies remain wherever you save or share them. Manage those copies through the destination provider. Before removing the app or clearing its storage, make and retain a usable backup.

Device backups and deletion

The portable encrypted archive is separate from backups made by your operating system. iOS may include app data in device or iCloud backups according to your settings. Android cloud Auto Backup is disabled for this app; device-to-device transfer behavior can vary by manufacturer. These facilities follow your device and provider settings.

Deleting a card hides it from the active library and records its deletion; original local records or images may remain in app storage. New portable backups omit the deleted card's content and images while keeping deletion state. Deleting a card does not remove previously exported copies or earlier account-owned data.
