Data Handling

Last updated: March 25, 2026

1. Data Architecture

Zend is built on a direct, peer-to-peer architecture. All data processing and file transfers occur locally on your device or between devices on the same local network (LAN). No data is ever transmitted to ZynthAI or any third-party cloud infrastructure.

2. Local Network Discovery

To identify other devices running Zend, the application uses local network discovery protocols. This involves broadcasting a non-identifiable signal within your own Wi-Fi or Ethernet network. This discovery process is entirely local and does not involve any internet-based directory or lookup service.

3. Peer-to-Peer Transfer

When you initiate a file transfer, a direct socket connection is established between the sending and receiving devices. The file is streamed bit-by-bit from one device to another without any intermediary storage or buffering on a server. The speed of the transfer is solely dependent on your local network hardware.

4. Temporary Data

During a transfer, small chunks of the file may be held in your device's RAM to manage the data stream. Once the transfer is complete or cancelled, this temporary memory is cleared. No log of the transfer history or the file contents is maintained by the application's core logic after the session ends.

5. Security & Encryption

Because Zend uses direct local connections, your data never leaves your physical environment unless you have manually configured your network to allow remote access. For added security, we recommend using Zend on encrypted Wi-Fi networks (WPA2/WPA3).

6. User Control

You have full control over which devices can see your device and which files are shared. Incoming transfers always require explicit user approval before the connection is established and data begins to flow.

7. Browser Access

When using the "Browser Bridge" feature, Zend starts a temporary local web server on your device. This server is only accessible from other devices within your local network and automatically shuts down when you close the app or disable the feature.
