What Duvio stores

The bills you enter: names, amounts, due dates, how they repeat, reminders, notes, confirmation numbers and payment history. With Pro, also your paydays.

This data is stored on your iPhone. The developer cannot see it.

iCloud sync (Pro)

If you turn on iCloud sync, your data is stored in your private iCloud database under your Apple Account so it can sync to your other devices. Apple handles this storage under its own privacy policy. The developer has no access to your iCloud data.

Notifications

Reminders are scheduled on your iPhone. They are not sent from a server. You can hide amounts in notifications and widgets in Settings.

Purchases

Duvio Pro is bought through the App Store. Apple processes the payment. Duvio only receives confirmation that Pro is unlocked, never your payment details.

Importing and exporting

CSV files, pasted lists and screenshots are read on your iPhone and not uploaded anywhere. Exported CSV files and backups go only where you choose to save or share them.

Deleting your data

Deleting Duvio removes its data from your iPhone. To remove synced data, turn off iCloud sync first, or delete Duvio's data in iPhone Settings › [your name] › iCloud › Manage Account Storage.
