SecureDocs - Confidential Document Storage App

SecureDocs is an Android application that allows users to securely store confidential documents in the device's internal storage. These documents are protected with a PIN code, ensuring that only authorized users can access them. The app leverages Android's runtime permissions for file access, providing a secure way to handle sensitive files.

Features

• PIN Protection: Store and access confidential documents securely with a PIN code.
• Runtime Permissions: Uses runtime permissions to handle file access, ensuring the app respects Android's permission model.
• Secure Document Storage: Documents are stored in the internal storage, ensuring they are not accessible by unauthorized apps or users.
• File View & Delete: Ability to view stored files and delete them securely.

Prerequisites

• Android Studio
• Kotlin 1.4+ (or higher)
• Android SDK 30+ (or higher)
• Runtime permissions for storage access

Getting Started

1. Clone the repository:

   git clone https://github.com/ervg0203/SecureDocsApplication.git

2. Open the project in Android Studio.

3. Make sure to grant necessary permissions when prompted. The app requires access to internal storage to store and manage documents.

4. Build and run the app on an emulator or a physical device.

App Structure
