Data Protection

Your Financial Data Is Private

VaultSio is built with privacy as a core principle. We never sell your data, never share it with advertisers, and your financial information never leaves our secure infrastructure without your explicit action.

Encryption in Transit & at Rest

All data transmitted between the app and our servers is protected with HTTPS/TLS encryption. Data stored in the cloud is encrypted at rest using AES-256 — the same standard used by banks.

Firestore Security Rules

Your data in Firebase Firestore is protected by strict security rules. Only you — authenticated with your own account — can read or write your financial records. No other user or third party can access your data.

What We Never Do

We do not sell your data. We do not mine your transactions for advertising. We do not share data with third parties except where required for app functionality (e.g., Firebase for data storage, RevenueCat for subscription management).
