Overview of the Change
Previously, pre-order rule data was deleted two days after uninstallation.
With this update, we have changed the specification so that the relevant data is now deleted immediately after uninstallation.
Reason for the Change
When the app was reinstalled shortly after being uninstalled, residual data from the grace period frequently caused inconsistencies.
To prevent this and improve consistency upon reinstallation, we changed the deletion timing to be immediate.
