Security Information
At TransferFiles, security and privacy are core principles of our service. This page explains in detail how we protect your data during transfers and ensure your privacy.
Our Security Approach
TransferFiles was designed with a "privacy by design" approach. We believe that the most secure way to transfer files is to not store them on servers at all. That's why TransferFiles uses direct peer-to-peer connections for all transfers, ensuring your files never pass through our servers.
Our technical implementation prioritizes the following security principles:
- End-to-end encryption for all transfers
- No server storage of user files or messages
- Minimal data collection
- Temporary connection IDs
- Transport Layer Security for all website communications
WebRTC Technology
TransferFiles uses WebRTC (Web Real-Time Communication) technology for direct browser-to-browser connections. WebRTC is an open-source project supported by major technology companies and browsers that provides secure, real-time communication capabilities.
How WebRTC Secures Your Data
WebRTC includes several security features that protect your transfers:
- DTLS (Datagram Transport Layer Security): All WebRTC connections are encrypted using DTLS, which is similar to the encryption used in HTTPS websites. This ensures that even if someone intercepts the data packets, they cannot decode the contents.
- SRTP (Secure Real-time Transport Protocol): WebRTC uses SRTP to provide encryption, message authentication, and replay protection for audio and video streams.
- Perfect Forward Secrecy: The encryption keys are generated for each session and discarded after use, ensuring that past communications cannot be decrypted even if a key is compromised in the future.
Direct Peer-to-Peer Connections
When you use TransferFiles, your files and messages are transferred directly from one device to another through an established peer-to-peer connection. Unlike traditional file-sharing services, your files never pass through or get stored on our servers.
The only role our servers play is in the initial "signaling" process, which helps two devices find and connect to each other. Once the connection is established, our servers are no longer involved in the data transfer.
No Server Storage
One of the most important security features of TransferFiles is that we don't store your files or messages on our servers. This means:
- Your files cannot be accessed by our team
- Your files aren't vulnerable to server breaches
- There are no lasting copies of your data after the transfer is complete
- We don't analyze, scan, or process the content of your transfers
This "zero storage" approach significantly reduces the security risks associated with traditional file-sharing services.
Connection Security
Temporary Connection IDs
When you open TransferFiles, a random ID is generated for your session. This ID is temporary and is used only for establishing the connection. Once your session ends, the ID is no longer valid and cannot be used to connect to your device.
HTTPS Encryption
The TransferFiles website uses HTTPS encryption to protect all communications between your browser and our servers. This ensures that your connection ID and other session information are transmitted securely.

| Server Storage | None | Yes, on email servers | Yes, on cloud servers | None |
| End-to-End Encryption | Yes | Varies | Varies by service | No |
| Account Required | No | Yes | Yes | No |
| Physical Access Required | No | No | No | Yes |
Best Practices for Secure Transfers
While TransferFiles is designed to be secure, here are some additional best practices to ensure the highest level of security for your transfers:
- Use private networks: When possible, avoid transferring sensitive files over public Wi-Fi networks.
- Verify the recipient: Always make sure you're connecting to the intended recipient before sending sensitive files.
- Password-protect sensitive files: For highly sensitive data, consider encrypting or password-protecting your files before transferring them.
- Keep your browser updated: Always use the latest version of your browser to ensure you have the most up-to-date security features.
- Disconnect after transfers: Once your transfer is complete, disconnect the session if you don't need to send additional files.
Security Updates and Vulnerability Reporting
We continuously monitor and update TransferFiles to address security vulnerabilities and implement the latest best practices. If you discover a security vulnerability in TransferFiles, please report it to us at [email protected].
