the Tralance mobile application (the "App"). We are highly committed to protecting user privacy. This Privacy Policy outlines how your data is processed, stored, and protected within the App.

1. Core Privacy Philosophy: Zero Data Collection

Tralance is designed from the ground up as a fully decentralized, offline personal finance assistant.

• No Server Uploads: The App does not possess any internet communication libraries (e.g., Ktor, Retrofit) or cloud integration. We do not host, collect, upload, or share any of your transactional data, personal identifiers, or app logs to external cloud servers.

• No Third-Party Analytics: We do not embed third-party tracking SDKs, marketing tags, or advertising networks that transmit data off your device.

• No External Accounts: The App works entirely locally; it does not request bank logins, API access, or credit card linking.

2. Permissions and Local Data Processing

To automate financial tracking, the App utilizes specific Android framework features. All processing happens strictly on-device in real-time:

• SMS Permissions (RECEIVE_SMS & READ_SMS): If granted by the user, our local system (SmsReceiver & SmsParser) reads incoming transactional SMS notifications. This logic extracts currency values (INR), amounts, and merchant tags (e.g., brand mapping) purely to represent them on your dynamic dashboard. The raw text and parsed results are immediately written directly to your local database and are never broadcasted externally.

• Biometric Authentication (androidx.biometric): The App relies on the Android OS biometric prompt layer to protect access to your financial dashboard. We do not access, process, or store your actual fingerprint or facial recognition data.

• Local Cryptographic Storage: Data required to operate the application (such as local preference flags) are managed using (androidx.datastore.preferences).

3. Advanced Security Architecture

Even though your financial logs never leave your phone, we implement enterprise-grade security to prevent unauthorized local access:

• Database Level Encryption: All transactions, merchant configurations, and internal application tables are stored in a relational Room database protected natively via SQLCipher and full AES-256 bit encryption.

• Anti-Screen Capture: The application enforces layout safety parameters that disable programmatic screenshots or screen recordings on secure states to prevent background overlay malware exploitation.

4. Children's Information

Since Tralance operates completely offline and transmits zero user data over the internet, we do not knowingly or unknowingly collect, aggregate, or store personal information from children under the age of 13, adhering strictly to COPPA guidelines.

5. Compliance and Policy Evolution

As Tralance operates autonomously on the user’s device without checking into an active server infrastructure, any revisions to this Privacy Policy will be announced transparently by publishing an updated document version inside the official Google Play Store application listing.
