Android Platform

TrueLedger provides a standard native experience on Android with a focus on security and performance.

🛠️ Technical Implementation

1. Persistence & Encryption

• Database: Uses sqflite_sqlcipher for a fully encrypted SQLite database.
• Key Management: The encryption key is generated locally and stored in Android Keystore using the flutter_secure_storage plugin (using AES/RSA encryption).

2. Notifications

• Plugin: flutter_local_notifications.
• Customization: Uses a custom notification icon and supports daily reminders even when the app is in the background.
