Architecture Commitment
Jal-Aushadhi is engineered under a strict Zero-Telemetry, Offline-First Architecture. We do not operate remote application servers, databases, analytics loggers, or telemetry agents. Zero bytes of user data ever leave your physical device.
We collect zero personal, health, biometric, or behavioural data. The app operates as an autonomous sandboxed vault.
- No Cloud Accounts: No signup, login, email verification, or authentication servers.
- No Analytics SDKs: No Google Firebase Analytics, Mixpanel, Sentry, or third-party behavioral trackers.
- No Advertising: Zero advertising SDKs, tracking pixels, or cross-app ad identifiers (IDFA/GAID).
- 0 Network Requests: The app executes cleanly in Airplane Mode with Wi-Fi and Cellular turned off.
All entries—including medication names, dosages, schedules, stock counts, water volumes, and body weight metrics—are stored exclusively in a private, sandboxed SQLite database file residing on the device's internal filesystem.

| Hydration Logs & Goals |

When the optional Biometric Vault Gate is activated, authentication is delegated directly to your operating system's hardware-isolated security subsystem (Android BiometricPrompt / iOS LocalAuthentication Secure Enclave).
Jal-Aushadhi receives only a binary verification result (authorized / rejected). The application never accesses, reads, processes, or stores your fingerprint or facial scan data.
You retain 100% sovereignty over your health information.
- Cryptographic Vault Backup: Export your full database into a portable JSON document at any time. Vault exports include SHA-256 integrity checksums.
- Clinical PDF Adherence Export: Generate offline vector PDF adherence summaries locally for doctor consultations without cloud processing.
- Permanent Data Deletion: Clicking "Clear All Data" in Settings triggers a clean SQLite transaction that permanently wipes all tables and reset the local database. Uninstalling the app also purges the application sandbox.
