Privacy at WeeTransfer.uk

Anonymous by design.

You do not need an account, and WeeTransfer.uk does not fingerprint your browser.

How this browser remembers

A private, secure cookie identifies files uploaded from this browser. It is never included in public links. If you clear it or change device, management access cannot be recovered.

Cookie policy

We use only essential cookies that make WeeTransfer.uk work. We do not use advertising, social-media, or cross-site tracking cookies, and we do not ask third parties to place cookies through this site.

Cookie Purpose Duration
__Host-WeeTransfer.Owner Lets this browser view and manage files it uploaded. Its random value is stored securely and is not used in public sharing links. Up to 270 days
__Host-WeeTransfer.Antiforgery Helps protect forms and upload actions from forged requests. Browser session

Both cookies are first-party, secure, and HTTP-only, so browser scripts cannot read them. You can remove them in your browser settings; doing so removes access to the My files list for uploads made from this browser.

Anonymous usage statistics

We record limited operational statistics so we can understand site usage and keep the service reliable: the page or action category, request method, response status, duration, upload size where applicable, and the anonymous upload-owner record when one is already available. We do not use cookies for analytics, and these records are deleted after 90 days.

How your file travels

WeeTransfer offers two ways to send a file. The important difference is whether we temporarily store a copy.

Server Share

Best when the other person will download later.

Your browser Uploads the file
WeeTransfer Stores it briefly
Their browser Downloads the file
The file and the small amount of information needed to manage it are automatically deleted within 72 hours.

Quick Share

Best when both people are online together.

Your browser Sends the file
Their browser Receives the file
WeeTransfer never receives or stores a copy of the file.

Quick Share, in plain English

Quick Share is like handing a file directly to someone. Both people keep the page open, and the file moves from one browser to the other through an encrypted connection. WeeTransfer helps the browsers meet, but the file itself is not uploaded to or kept by us.

If the two browsers cannot connect directly, Cloudflare acts like a delivery route for the encrypted file. Cloudflare can see the network addresses involved and how much data passes through, but not the contents of the file. The four-digit PIN stops working after 10 minutes if nobody uses it.

For the technically curious

Quick Share technical details

File bytes travel over an encrypted WebRTC DataChannel. WeeTransfer temporarily handles signalling messages so the browsers can negotiate the connection, while Cloudflare provides STUN discovery and short-lived TURN relay credentials. If TURN is needed, Cloudflare relays encrypted traffic and necessarily processes both browsers' IP addresses and the relay byte count.

Unused four-digit PINs expire after 10 minutes. Connection details are removed after the transfer, when the session expires, when either browser disconnects, or when the service restarts.

To control relay costs, WeeTransfer keeps a random session ID, the declared file size, a conservative reserved data allowance, completion status, and the successfully reported byte count. We do not record the filename or file contents. Monthly usage records are retained for up to 13 months.
