No bank connection.
Marble does not connect to banks, credit cards, brokerages, or financial aggregators. You decide what goes into the app.
Private by design.
No ads. No selling of your personal finance data. Your budget stays in your Apple ecosystem.
No Marble financial-data database.
Your financial data is stored on your device and, when iCloud synchronization is enabled, in your personal iCloud account.
iCloud can be disabled.
Sync and sharing use Apple iCloud and CloudKit. iCloud synchronization is enabled by default when available, and you can disable it in the app.
AI stays local by design.
The Marble assistant is designed around Apple's on-device foundation model on eligible devices. Marble does not receive your assistant questions or answers.
The full policy is available in plain sight.
The public privacy policy explains site forms, support emails, iCloud sync, shared budgets, and deletion controls in more detail.
