Fair questions

Where does my data actually live?

On your iPhone. CoreSpend has no servers and no accounts — nothing to breach, nothing to sell. Sync happens only through your personal iCloud, which we can't read.

What happens when I get a new iPhone?

Sign into the same iCloud account and your budget is there. Same for a reinstall.

Why $0.99 once instead of a subscription?

A budgeting app that charges monthly works against you. You pay once, you own it — every future update included.

Does it work offline?

Completely. Everything is on-device; iCloud sync just catches up when you're back online.

Can Siri really log an expense?

Yes — "Hey Siri, log a $4 coffee" adds it without opening the app. Widgets cover the glancing; Siri covers the hands-full moments.
