CrossSync
Local clipboard synchronization between Android and Desktop without cloud services.
CrossSync keeps clipboard history, categories, pairing, and local network transfer in one focused app.
What the app does
Clipboard history
Keep copied text, links, and notes available after the original source is gone.
Categories
Organize copied items by context and quickly return to what matters.
QR pairing
Connect Android to the desktop server with a local QR pairing flow.
LAN first
Move data between devices over your network instead of a cloud clipboard.
Copy on one device, continue on another
The desktop app watches the local clipboard, Android connects to it, and copied content becomes available where you need it next.
Desktop stores clipboard history locally.
Android pairs with the desktop server over LAN.
Selected clipboard items can be sent or reused across devices.
QR Pairing
Local pairing without a cloud clipboard.
