Privacy Policy
Last updated August 19, 2026
The short version
FileTransferX is designed so that your files never need to be stored anywhere but your own devices. There are no accounts, no file uploads to a permanent server, and no tracking cookies. This page explains exactly what that means in detail.
Your files
When you send a file with FileTransferX, it is transferred directly from your device toward the receiving device in small chunks. FileTransferX does not copy your files to a database or a permanent file store, and it does not retain them after a transfer session ends. If a direct connection between the two devices isn't possible on a given network, a relay server may briefly facilitate the connection so the transfer can still complete — that server passes data through in transit and is not designed to keep a copy of it.
Pairing information
Starting a send session generates a temporary QR code and a short transfer code used only to pair two devices for a single session. This code is not tied to your identity, is not reusable once its session ends, and is discarded shortly after.
Accounts and personal information
FileTransferX does not have user accounts. We don't ask for your name, email address, or any other personal information to use the core transfer feature. If you email us through theContact Us page, we use that address only to reply to you.
Cookies and local storage
FileTransferX stores a single preference — your light or dark theme choice — in your browser's local storage. This value stays on your device and is never transmitted to us. We do not use tracking cookies, and we do not run third-party advertising or analytics scripts that follow you across other websites.
Technical connection data
Establishing any connection over the internet requires devices to exchange basic network information, such as IP addresses, in order to find each other and, where necessary, route a relayed connection. This information is used only to facilitate your transfer and is not logged for tracking purposes or linked to an identity we hold.
Changes to this policy
If this policy changes in a meaningful way, we'll update the date at the top of this page. Continued use of FileTransferX after a change means you accept the updated policy.
