Backing up data from a local-only app

What local-only actually means for your backups

An app with no account and no cloud sync stores everything only on the device it's installed on. That's good for privacy, since nothing sits on a company's server to be breached, but it also means there's no automatic copy anywhere else. If the phone is lost, damaged or reset without a backup, that data is gone.

This is different from most apps with an account, where losing the phone doesn't mean losing the data, since a server copy still exists. A local-only app shifts that responsibility entirely to you.

The two layers: device backup and a manual export

Your phone's own backup system, whether that's an encrypted backup to a computer or a cloud backup of the whole device, typically includes each app's local data as part of a full device backup. That's the first layer, and it happens automatically if it's already set up. A manual export file from within the app is the second layer, a portable copy you control directly.

Setting up a backup routine for a local-only app

Neither layer alone is a complete plan; using both closes most of the realistic gaps.

1. Confirm your phone's own backup system is turned on and actually completing backups, not just enabled.
2. Check whether that backup includes app data, not just photos and settings.
3. Use the app's own export feature to save a file separately from the device backup.
4. Store the exported file somewhere outside the phone, like a computer or a cloud drive you control.
5. Repeat the manual export periodically, since it's a snapshot at the moment you create it.

Where to store an exported file safely

An exported file often contains detailed personal financial information, so treat it the way you'd treat a bank statement: store it somewhere access-controlled, not a shared drive or an unencrypted email attachment sitting in your inbox indefinitely.

Common questions

Does an export file update automatically?

No. An export is a snapshot at the moment you create it, so it goes out of date as soon as you enter new information. It's worth repeating the export periodically rather than treating one copy as permanently current.

Is a device backup enough on its own?

For most people, yes, as long as it's actually running and includes app data. A manual export adds a second, more portable copy that doesn't depend on restoring an entire phone, which is useful if you just want the debt data specifically.

What file format should I expect from an export?

That depends on the specific app; a CSV file is common for this kind of data, since it opens in a spreadsheet program and is straightforward to read or re-import later.
