Privacy Policy

Last updated: July 28, 2026

Transfer does not collect, store, or transmit any of your personal data. That is not a promise — it is a consequence of how the app is built. There is no server and no account system, so there is nowhere for your data to go.

What the app collects

Nothing. Transfer contains no analytics, no tracking, and no crash reporting. It sends no data to us or to any third party.

Where your data lives

  • Message history and file records are stored in a local database on your own computer.
  • Received files are written to the download folder you choose.
  • Screenshots are sent, copied, or saved at your direction.
  • Settings and this device's identity (device name, self-signed certificate) are kept in the app's local data folder.

Uninstalling the app or deleting those folders removes this data. We hold no copy of any of it.

How data travels

Files and messages move directly between two devices over an encrypted (TLS) connection, trusted on first use by pinning the peer's certificate fingerprint. No relay server is involved, and the traffic does not leave your local network.

What is broadcast on your local network

So that devices on the same network can find each other automatically, Transfer broadcasts — within your local network only — the device name, its IP address and port, and its certificate fingerprint. This is used solely for discovery and connection setup. It never leaves the local network and is never sent to us.

System permissions

  • Local Network — required to discover peers and establish direct connections. Core functionality depends on it.
  • Screen Recording — used only by the built-in screenshot feature. File transfer works without it.

About this website

This site is hosted on Cloudflare, which produces standard access logs (IP address, browser identifier, timestamp) used for security and to count downloads. Those logs are used in aggregate, are not used to identify individuals, and are not linked to anything inside the app.

Third parties

We do not sell, share, or transfer any data — there is none to share.

Children's privacy

This app is not directed at children and collects no personal information from users of any age.
