Setup Syncing Between Your Devices

If you use LockYit on more than one device - say your phone and your laptop - you probably want an item you add on one to show up on the other. Local Sync does exactly that, keeping your own devices in step over your local Wi-Fi network without ever touching a cloud server. Here is how to set it up.

How Local Sync Keeps Your Data Private​

Local Sync works only when your devices are on the same Wi-Fi / local network and both are unlocked. Nothing is ever sent to the internet or stored on LockYit's servers, and all traffic between your devices is end-to-end encrypted (RSA-2048 + AES-256-GCM). Your master password and keys are never transmitted.

Because syncing is between your own devices, every device involved must be signed in to the same LockYit account.

Pairing Two Devices​

You pair your devices once. After that, they recognise each other automatically whenever they are on the same network and unlocked.

  1. Make sure both devices are on the same Wi-Fi / local network and have LockYit open and unlocked.
  2. On both devices, open the Local Sync screen and turn it on with Enable Local Sync.
  3. In the My Devices section, tap Pair (the + button in the section header). The devices find each other automatically.
  4. On one device, choose the other from the discovered list and start pairing.
  5. A 6-digit code appears on the first device - enter it on the second to confirm.

Once paired, the devices appear in each other's My Devices list and begin syncing.

For a full walkthrough, see the Local Sync documentation.

Adding More Devices​

You can sync as many of your own devices as you like - a phone, a tablet, and a laptop can all share the same vault. You do not have to pair every device with every other one. Each pairing connects two devices directly, but your vault converges across all of them, so to add a third device you just pair it with one device you have already set up.

See Setting up multiple devices for the details.

How Changes Travel​

  • Instant on change - adding, editing, or deleting an item syncs to your online paired devices right away.
  • On reconnect / unlock - when a paired device comes back online, or you unlock the app, it syncs immediately.
  • Background safety-net - a periodic check catches anything missed, running more often after recent activity and relaxing when idle to save battery.
  • Pull to refresh - pull down on the Local Sync screen to run a full, two-way manual sync with every online paired device.

A Few Tips​

  • Keep at least one device as your main device for adding and updating entries, to keep a clear source of truth.
  • Local Sync is not a backup. It keeps your live devices in step, but you should still take regular backups so you have restorable copies of your vault.
  • Both devices must be unlocked and on the same network for a sync to happen - there is no cloud relay in between.

Local Sync gives you an up-to-date vault on every device you own while keeping LockYit's strict offline-first, zero-knowledge philosophy fully intact. Turn it on from the Local Sync screen, and if you run into any trouble, the troubleshooting section has you covered.
