Sango Finance — Privacy Policy

Last updated: April 18, 2026

1. Our Privacy Philosophy

Sango Finance is built on the principle of “Privacy by Design.” We have zero access to your financial data.

2. Data Collection and Storage

Local Storage

All your financial data (accounts, transactions, amounts) is stored exclusively on your device within an encrypted database.

iCloud Backup (Optional)

If you enable synchronization, your data is transferred to your private Apple CloudKit database. This data is end-to-end encrypted by Apple. Sango Softwares cannot access it.

API Key Management

Your API keys are stored in the iOS Keychain, the most secure encrypted system layer, protected by hardware-level security.

3. Network Flow Security

To update asset prices, the application communicates with third-party data providers.

Data Minimization

Only asset identifiers (Ticker or ISIN) are transmitted. Your specific quantities and total portfolio valuations never leave your device.

Request Encryption

Your API keys are transmitted via secure HTTP headers (TLS 1.2+) where supported by data providers. For providers that require URL-based authentication, we rely on encrypted TLS tunnels to protect the transmission. This hybrid architecture ensures your credentials are protected by the highest level of security available for each specific service.

4. No Tracking Policy

Sango Finance contains no analytics tools, no advertising trackers, and no automated crash reporting that collects identifiable user data.

5. Your Rights (GDPR & International)

In accordance with global privacy standards, you maintain total control over your data. Since your information is stored on your device or your personal iCloud account, you can view, modify, or delete it at any time by uninstalling the app or clearing the database in the settings.
