LAN sync

LAN sync lets two devices exchange data directly over the same network, with nothing going through the cloud.

How to use

1. Connect both devices to the same Wi-Fi and open Moodiary on each.
2. On the sender, go to Sync → LAN and choose Send.
3. On the receiver, choose Receive and wait to be discovered.
4. On the sender, select the other device and confirm to start syncing.

Discovery uses mDNS, so you don't need to enter any address or account.

Transfer security

• Data is packed into entry-level AES-256-encrypted archives before transfer.
• The transfer protocol includes a version handshake to avoid data overwrites between old versions.
• Combine with end-to-end encryption for extra content protection.

Notes

• Can't find the device: check whether the router has "AP isolation / client isolation" enabled; public Wi-Fi often blocks device-to-device traffic.
• Slow speed: wireless speed depends on the Wi-Fi standard; 5 GHz networks are noticeably faster.
• Version differences: keep both devices on similar versions; before a large cross-version migration, make a backup first.
