Your data stays on your devices.

How QuickBridge works

When you connect two devices using QuickBridge, a secure peer-to-peer connection is created using WebRTC, the same technology that powers browser video calls. Files, messages, and clipboard data are sent directly between your devices over an encrypted channel.

Our servers are only used briefly to help your devices find each other. This is called signaling: an exchange of small connection hints, no file content. Once the two devices are connected, all transfers are direct, and the signaling channel is no longer in the path.

Files and transfers

• Files are never uploaded to or stored on any QuickBridge server.
• Transfers happen in real time, browser-to-browser, between the two connected devices.
• If you enable "Save incoming files to folder", files are written directly to the folder you chose on your device, through your browser's File System Access API, which we never see.
• Cancelled transfers are discarded immediately on both devices and are not retained anywhere.

Clipboard and messages

Clipboard sharing is opt-in and only active when you turn it on. Text snippets, links, and short messages travel through the same direct, encrypted channel as files. Nothing is logged or persisted by QuickBridge.

What's stored on your device

QuickBridge keeps a small amount of data in your browser to make the experience smoother. This data never leaves your device and we cannot read it.

• Device name

  So you don't have to rename it every session.

• Recent session history

  A short list of what you sent or received recently, for convenience.

• Auto-save folder handle

  Stored securely by your browser so the same folder can be reused next time.

• Preferences

  Things like clipboard sync on/off and PWA install hints.

You can clear all of this at any time by clearing your browser's site data for QuickBridge.

Security

• All connections use encrypted WebRTC data channels (DTLS), the same encryption used for browser video calls.
• A short verification code (SAS) is shown on both devices, so you can confirm you're connected to the right device and not to an imposter.
• No accounts, passwords, or personal data are required to use QuickBridge.

Analytics

We use privacy-respecting page analytics to understand which pages people land on, so we can improve the marketing site. We do not track files, messages, clipboard contents, or anything you transfer inside a session. We do not use advertising cookies and we do not build profiles of individual visitors.

What we don't do

• No file storage on our servers
• No cloud uploads or backups
• No user accounts or passwords
• No selling or sharing of data
• No tracking of what you transfer
• No third-party advertising trackers

Third-party services

QuickBridge uses a small set of services to function. None of them have access to the contents of what you transfer.

• Signaling

  Used briefly to help two devices discover each other. Carries only short connection hints, never file or message content.

• TURN relay (fallback only)

  If two devices can't reach each other directly because of a strict network, traffic falls back to a TURN relay. The relay forwards already-encrypted bytes; it cannot read them.

• Hosting

  The QuickBridge website itself is served from a standard web host. The host serves static pages and never sees the contents of your transfers.

Changes to this policy

If we ever update this page, we'll keep the language plain and the changes obvious. No hidden edits, no surprises.
