Privacy policy — UsbNetBridge

Last updated: 10 September 2026

UsbNetBridge shares USB devices from a USB host (today: an Android device with USB OTG) to a Windows PC on the same local network. It does not use a cloud account.

What the Android app does

Listens on your local network (USB/IP on TCP 3240, discovery on UDP 3241, events on UDP 3242) so the Windows client can find this device and attach USB devices you plug in.
Shows this device’s local IP address in the app so you can connect if automatic discovery fails.
Uses a foreground notification while sharing is on, so the server can keep running.
Asks for USB permission when you plug in a device. USB access stays on this device unless you tap Allow.

Data we collect

We do not collect, sell, or send your data to UsbNetBridge servers. There is no account, no analytics SDK, and no advertising.

Information that stays on your devices / LAN:

USB device names and identifiers (needed so the PC can attach the right device)
Local IP addresses of the USB host and the PC
Optional saved PC addresses and auto-connect preferences on the Windows client

Anyone on the same network who runs a USB/IP client could try to attach a device while the Android app is Started. Only start sharing on a network you trust. Do not port-forward TCP 3240 to the internet.

Permissions (Android)

Permission	Why
Internet	Talk to the PC on your LAN
Wi‑Fi / multicast	Find the app from the PC on the local network
USB host	Read/write the plugged-in USB device
Foreground service (special use)	Keep sharing alive while the screen is off
Notifications	Show that sharing is running

Children

UsbNetBridge is not directed at children and does not knowingly collect personal information from children.
