Privacy Policy

Last updated: April 2025

No files stored

Flow never stores your files. When you send a file, it travels directly from your browser to the recipient's browser over an encrypted WebRTC connection. Our servers are not involved in the data transfer at all.

Session tokens

When you create a share session, a short-lived token is stored temporarily in a Cloudflare Durable Object. This token is used only for signaling — coordinating the WebRTC connection between sender and receiver. It contains no file data and no personal information. It is automatically deleted when the session expires or is closed.

No accounts

Flow requires no account, login, or registration of any kind. We do not collect your name, email address, or any other personal information.

No tracking

We do not use analytics, tracking pixels, cookies, or any third-party tracking services on this site.
