Local-first speed, optional sync: how Atlantic handles your data
Why Atlantic runs locally by default and when to turn on sync across iPhone and iPad.
Atlantic is designed local-first: your day-to-day tracking should feel instant, even when you are offline. Sync is optional—something you turn on when you want the same picture on every device.

What local-first means for you
- Log transactions, browse budgets, and run reports without waiting on the network.
- Core workflows keep working in airplane mode or poor connectivity.
- You stay in control: the app is useful before you create an account.
When to enable sync
Turn on sync when you use both iPhone and iPad (or replace a device) and want:
- The same accounts, categories, and transactions everywhere
- Backup aligned with your signed-in account
- Fewer manual exports when switching devices
Configure it under Settings → Sync in the app. For policy details, see our Sync & privacy page and Privacy Policy.
What we do not do
- We do not sell your transaction history.
- We do not require sync to use basic tracking.
- We do not replace professional financial, tax, or legal advice.
