Your Receipts. Your Vault. Your Privacy.
Hardware-encrypted expense tracking that never leaves your device—private by design, offline by default
Three Steps. Zero Compromises.
1. Snap Receipt
ML Kit OCR extracts vendor, amount, date, and items instantly. Multi-currency support with offline exchange rates.
2. AI Categorizes
Gemini Nano runs on-device to automatically categorize your expense. No cloud, no tracking, no waiting.
3. Vault Secures
Encrypted and stored in hardware-backed vaults with optional biometric protection. Your data, your device, your control.
Privacy You Can Verify
No marketing claims. Here's exactly how your data stays secure.
Hardware Keystore
Encryption keys stored in Android's hardware security modules (TEE/StrongBox). Keys never touch RAM and cannot be extracted.
Per-Record Encryption
Each expense encrypted individually with AES-256-GCM. Unique IVs and authentication tags prevent tampering.
SQLCipher Database
Full-database encryption. Even with device storage access, attackers see only encrypted blobs.
On-Device AI
ML Kit OCR and Gemini Nano run locally. Receipt images and text never leave your phone.
Offline-First
Internet only needed to download AI models via Google Play. Everything else runs locally—zero tracking.
Open Design
Detailed privacy policy and architecture documentation. No hidden data collection.
Common Questions
How does offline AI work?
ML Kit (OCR) and Gemini Nano (categorization) run entirely on your device. Models download once via Google Play's secure delivery system and stay local. No internet needed after that.
How do I back up my data?
Use Android's built-in backup or share vaults via secure Bluetooth (BLE) with trusted devices. Export to CSV/JSON anytime—you own your data.
Is this really free?
Yes. Receipt scanning, encryption, vaults, and AI categorization are free and always will be. We believe expense tracking shouldn't cost you your privacy or money.
What Android version do I need?
Android 13+ (API 33). This ensures access to StrongBox Keystore, modern biometrics, and latest security features.
