Your data

By default, everything is stored on your device. Your data is never sold, nor used for commercial or advertising purposes, and it is shared with no partner. Your financial data (budget, wealth, calculators) is never exploited; and if you turn on sync between your devices, it only travels end-to-end encrypted: no one, not even us, can read it. You can delete your account and all your data directly from the app.
