April 2022 update information!
You only need to update if you are using Android 11 or higher.
If you are using Android 10 or lower, you do not need to update.

From the Android 11 version, the policy has been changed to prevent the use of the previously used backup folder as access rights to the folder used for backup/restore are restricted according to the Android policy. Therefore, it is possible to use the app normally after installation on Android 11 or higher mobile phones, but errors may occur during backup and recovery.

When backing up and restoring, the [My Documents] - [CarManager] folder was used previously, but from Android 11, the [My Documents] - [Android] - [data] - [App Name] folder is used.

Please make a full data backup before updating.
When restoring, copy the previously backed up file to a new folder and the backup file will be visible.
※ Please refer to [Notes] in the upper right menu of the first screen.
Be sure to make a full backup before the update and a full backup after the update.
