Data Storage and Sync

Local Storage

Your outline data is stored locally on each device as a SQLite database. Each device maintains its own independent copy, so the app works fully offline.

• Even if you disable iCloud sync, your data remains intact on the device.
• Deleting the app removes the local database. If iCloud sync is enabled, your data can be restored by reinstalling the app.

iCloud Sync

When iCloud is available, your outlines sync across Apple devices via CloudKit.

• Data syncs automatically through your iCloud account. No login or account creation is required.
• Your data is encrypted by Apple. The developer cannot access its contents.
• Sync uses Apple's CloudKit framework — the same infrastructure behind iCloud Drive, Notes, and other Apple apps. Your data is stored in your personal iCloud container and is not shared with anyone.

Sync Timing

Changes are typically synced within a few seconds, but delays can occur depending on network conditions and iCloud server load. In some cases, syncing may take a minute or longer. If you edit the same row on two devices before a sync completes, the most recent change is kept.

Settings

In the Sync tab of Settings, you can turn iCloud sync on or off. When disabled, your data stays on the current device only.
