Security & Cryptographic Architecture
Your financial data is sacred. We built Smart Money Tracker with a privacy-first foundation: local device sandboxing, biometric hardware locking, and zero data resale.
Biometric Lock
Native Android hardware biometric prompt (Fingerprint & Face Unlock) guards your local SQLite database from physical intrusion.
TLS 1.3 Encryption
Every REST API payload traveling between your Android app and cloud database is encrypted with modern 256-bit SSL protocols.
SHA-256 Ledger Seal
Exported financial statements include a cryptographic SHA-256 checksum fingerprint to prove tamper-proof authenticity.
Zero Data Resale
We never monetize your spending habits or sell transaction records to credit bureaus or advertising networks.
1. Local Device Sandbox Isolation
On Android, Smart Money Tracker operates inside a secure application sandbox. The Room/SQLite database is stored in internal protected storage, strictly inaccessible to other apps installed on your device. Even if your phone is connected to unverified Wi-Fi networks, your financial records remain locked behind native Android security controls.
2. Certified Read-Only Financial Statements
Financial accountability requires tamper-proof records. When generating an Executive Dashboard Statement or downloading a Protected Excel Sheet, our engine calculates a cryptographically verified SHA-256 digest of your timestamp and ledger ID, ensuring that financial figures cannot be manipulated after download.
3. Zero-Knowledge Compliance & Account Deletion
You have full ownership of your data under our Privacy Policy. At any moment, you can trigger a full database JSON export, or permanently purge all account records from our cloud servers with a single click in your settings.
