What is Cloud Auto Sync?

Card Diary's Cloud Auto Sync means that Card Diary will fully auto-sync and backup all your diaries to your private cloud server so that even if you lose your phone, you can get your diary's data back on your new phone. Or after you uninstall Card Diary and reinstall Card Diary, all your diary data will restore to your phone from your private cloud. Also, the user's private cloud storage ensures the security and privacy of user diary data.
