Zoneck Transfer Documentation

Everything you need to set up, operate, and troubleshoot Zoneck Transfer across Android, Windows, macOS, Linux, and iOS. Zero cloud servers, pure peer-to-peer Wi-Fi speed.

Getting Started in 4 Easy Steps

Zoneck Transfer is completely decentralized. You do not need to register an account, sign in, or pair devices via Bluetooth PINs.

1

Connect to the Same Network

Ensure both your sending and receiving devices are connected to the same Wi-Fi router, local Ethernet switch, or smartphone Mobile Hotspot.

2

Launch Zoneck on Both Devices

Open Zoneck Transfer. Each device generates a friendly pseudonym (e.g., "Swift Falcon" or "Cosmic Star") or you can customize your device name in Settings.

3

Select Your Payload

In the Send tab, choose what you want to share: individual files, entire directories, photos/videos, or clipboard text snippets.

4

Tap the Recipient

Nearby devices will appear automatically in the radar grid. Tap the target device. The recipient approves the transfer with one tap, and transfer streams at line rate.

How Zoneck Operates Under the Hood

Unlike cloud storage tools (Google Drive, WeTransfer, Dropbox) that upload your confidential files to a third-party data center before downloading them back, Zoneck transfers bits directly across your local network interface controller (NIC).

100% Local: Your transfers never leave your living room or office. If your broadband internet cable is physically unplugged, Zoneck continues transferring at gigabit speeds over local Wi-Fi.

Multicast Peer Discovery

Zoneck broadcasts UDP multicast beacons on the local subnet. When an active node detects a beacon, it sends back an announcement containing its device alias, platform model, and temporary TLS public fingerprint.

Network Architecture & Port Disclosures

For store review compliance and network administrator reference, the exact communication specifications are detailed below:

Parameter Default Value Description
Default Port 53317 Standardized wire protocol port (configurable in Settings).
Discovery Transport UDP Multicast Multicast address 224.0.0.167:53317 and broadcast fallback.
Payload Transport TCP / HTTPS / TLS v1.3 Encrypted HTTP streaming chunks with zero-copy file I/O.
WAN / Internet Access None Required Completely air-gapped capability. Works on offline LANs.

Firewall Configuration

If another device cannot discover your PC or fails during transfer handshake, your host operating system firewall is likely blocking inbound traffic on port 53317.

Windows (Windows Defender Firewall)

When launching Zoneck for the first time, Windows will prompt you to allow network access. Check both "Private networks" and "Public networks". If missed, execute this command in PowerShell as Administrator:

New-NetFirewallRule -DisplayName "Zoneck Transfer" -Direction Inbound -LocalPort 53317 -Protocol TCP -Action Allow
New-NetFirewallRule -DisplayName "Zoneck Discovery" -Direction Inbound -LocalPort 53317 -Protocol UDP -Action Allow

macOS

Navigate to System Settings > Network > Firewall. Ensure Zoneck Transfer is permitted for incoming connections. Also verify that under Privacy & Security > Local Network, Zoneck is enabled.

Linux (UFW)

For Ubuntu, Debian, or Linux Mint users running Uncomplicated Firewall (UFW):

sudo ufw allow 53317/tcp comment 'Zoneck File Transfer'
sudo ufw allow 53317/udp comment 'Zoneck Device Discovery'

Hotspot Mode: Sharing Without Any Wi-Fi Router

You do not need a broadband Wi-Fi router to use Zoneck. You can transfer files anywhere (on a train, camping, or in a studio):

  1. Enable Personal Hotspot / Mobile Hotspot on Phone A (mobile cellular data can remain OFF).
  2. Connect Phone B, your laptop, or PC to Phone A's hotspot Wi-Fi network.
  3. Open Zoneck Transfer on both devices. They will detect each other and transfer at direct 5 GHz Wi-Fi direct speeds (up to 120 MB/s). No cellular data or balance is consumed.

Troubleshooting Common Issues

Wi-Fi Client Isolation (Guest Networks): Many public Wi-Fi networks (hotels, airports, universities) turn on "AP Isolation", forbidding devices from seeing each other. Use Hotspot Mode or Direct IP mode to circumvent this.

1. "Devices do not appear in the discovery list"

  • Check VPNs: If a VPN is active on either device (e.g. Proton, Nord, Cloudflare WARP), local LAN traffic might be routed into the virtual tunnel. Temporarily pause the VPN or enable "Allow Local Network Access" in your VPN app.
  • Manual IP Transfer: In Zoneck, switch to the Send tab, tap the Troubleshoot / Manual IP button, enter the recipient's local IP (visible under their Receive screen, e.g. 192.168.1.45), and send directly.

2. "Android kills the app during large transfers"

Modern Android OEMs (Xiaomi HyperOS, Samsung OneUI, Huawei) aggressively kill background processes. To enable uninterrupted gigabit transfers of 50 GB+ files:

  • Go to Settings > Apps > Zoneck > Battery Saver.
  • Select "No Restrictions" or "Unrestricted".

Cryptographic Security Model

Zoneck Transfer employs TLS v1.3 encryption across all communication links. When the application launches, an ephemeral ECDSA certificate keypair is generated directly in RAM. No private keys are ever written to disk or sent across the network.

All transfers require manual sender verification and recipient consent unless you explicitly turn on the "Quick Save" option for trusted family or office devices.
