If you switch devices or uninstall the app, this status will not transfer automatically. To restore Pro on a new device, use the "Restore Purchases" option in the App Store.

5.5 Limitations on Cross-Device Use

Because this Application does not maintain accounts and does not upload data to the cloud, Pro status does not automatically sync across devices. To use Pro on multiple devices, please run "Restore Purchases" in the App Store on each device separately.
