2. Data Collection and Storage

A. Personal User Data (Local Storage Only)

We strictly adhere to a local-first data policy.

Card Details & Images: Any credit cards, debit cards, IDs, or documents you scan or enter manually are stored locally on your device using an encrypted database (Android Room).

No Cloud Sync: We do not upload, sync, or store your personal card details, images, or sensitive user data on any external server.

Control: You have full control to edit or delete this data at any time directly within the app.

B. Camera & Image Data

Usage: We use the device camera to scan cards and documents.

Processing: Image processing and text recognition (OCR) are performed on-device using Google ML Kit. We do not transmit video feeds or raw images to our servers.

C. Technical & Usage Data (Third-Party Collection)

While we do not collect your personal content, our application uses third-party SDKs (Software Development Kits) for functionality, advertising, and analytics. These partners may collect:

Device Identifiers: Advertising ID (GAID), Android ID.

Usage Data: Crash logs, performance data, and app interaction metrics.

Coarse Location: Approximate location data derived from IP addresses for ad targeting.

3. Permissions Usage

We request the following permissions to provide specific features:

CAMERA: Required to scan credit cards and documents physically.

Offline Capability: The core functionality of viewing and editing cards works entirely offline, reducing exposure to internet-based threats.
