HappySupport
Moments are kept on this device. Use Settings → Export backup to save a copy to Files. Settings → Restore backup replaces the current collection after confirmation. There is no automatic cross-device sync. Losing the device or deleting Happy can lose entries without a usable backup.
Photo import uses the system picker. An image stored only in iCloud may need a connection before import can finish. For recording, allow microphone access in iOS Settings if you previously denied it. Reminders need notification permission and their delivery time is managed by iOS.
