LINE deleted my old messages without warning, how can I recover them or prevent this again?

If your LINE messages were deleted without warning, recovery options depend on your backup status.

If you had enabled chat backups to iCloud (iOS) or Google Drive (Android), you can restore them by reinstalling LINE and selecting "Restore Chat History" during setup.

Ensure you're logged into the same account used for the backup.

Additionally, if you had set a backup PIN, LINE allows restoration of chats from the past 14 days even without a full backup.

Without any backup or PIN, recovery becomes challenging.
