ONYX doesn’t sync your Favorite Chats through the central server. That’s intentional — your saved notes, files, and drafts are yours, and routing them through a server defeats the point of a privacy-focused messenger.

But sometimes you need those notes on a different device. You wrote something on your laptop and want it on your phone. WardLink handles that locally, over your own network, without touching any server.

How it works

1. Open the chat or saved message you want to transfer
2. Tap Share via WardLink → Send
3. A QR code appears on your screen
4. Open ONYX on the second device and scan it
5. The chat transfers directly, device to device

Works both ways — phone to desktop, desktop to phone.

What happens under the hood

• No account linking
• No cloud relay
• No data leaves your local network
• Connection encrypted with AES-256-GCM
• Devices find each other via UDP broadcast on your LAN

WardLink is still experimental. Right now it handles Saved Messages — broader sync support is planned. If you run into issues or have ideas for what else should transfer this way, comments are open.

One direction I’m considering: full passive LAN sync. While your devices are on the same network, all chats sync automatically in the background — no QR codes, no manual steps. Entirely local, optional, off by default. Curious whether that’s something people would actually use or if it’s overkill?
