Terms

Last updated 2 November 2026

peer.io is free and provided as it is. Don’t use it for anything illegal or harmful. We never see what you send, so you’re responsible for it.

1. About peer.io

peer.io is a free service run by PeerX Ltd, a company registered in England and Wales (company number 07476951) whose registered office is at Tempo House, 15 Falcon Road, London SW11 2PJ (“we”). It helps two web browsers connect so that one person can send a file directly to another. By using peer.io you agree to these terms.

2. How it works

Files and messages travel directly between the two browsers over an encrypted connection. We don’t store, view or check them. A transfer only works while the sender keeps their page open.

3. Using peer.io responsibly

You must not use peer.io to:

• send or receive anything illegal, including child sexual abuse material and terrorist content;
• send malware or anything designed to damage or gain access to someone else’s device;
• share material you don’t have the right to share, such as content that infringes copyright or someone’s privacy;
• harass, threaten or defraud anyone;
• try to join transfers that aren’t meant for you, for example by guessing codes, or to overload or disrupt the service.

We may block access to peer.io from any connection we reasonably believe is being used to break these rules.

4. What you send

You keep all rights in your files. We never receive them, so we claim no rights over them. We can’t scan files for viruses or anything else, so only accept and open files from people you trust.

5. Receipts

The receipt is produced and signed by the two browsers. It shows that the file each browser handled had the same fingerprint (SHA-256 hash). The start and finish times on it come from the recipient’s device.

Where our seal is available, we also add our own signature to a scrambled value worked out from the receipt, together with the time from our clock. The seal shows only that a receipt with exactly those contents existed at that time. We never see the receipt itself, we don’t store receipts or seals, and we don’t confirm that anything a receipt says is true.

A receipt doesn’t prove who either person was: the signing keys are created for each transfer and aren’t linked to anyone, and anyone with the code or link can receive a transfer. Anyone can check a receipt’s signatures and seal at peer.io/verify.

6. Availability

peer.io is provided free and “as is”. We may change, pause or stop it at any time. Transfers can fail or be interrupted, so always keep your own copy of anything you send.

7. Our liability

Nothing in these terms limits liability that cannot legally be limited, including for death or personal injury caused by negligence, or for fraud. If you use peer.io as a consumer, your statutory rights are not affected.

Otherwise, because peer.io is a free service, we are not liable for loss of data, loss of profit or business, or any indirect loss, and our total liability to you for anything arising from your use of peer.io is limited to £100.

8. Reporting misuse

If you think peer.io is being used to break these terms, email [email protected]. We can’t see transfers, but we can act on connection details and block misuse.

9. Law

These terms are governed by the law of England and Wales, and the courts of England and Wales have jurisdiction. If you live in Scotland or Northern Ireland, you can also bring a claim in your local courts.

10. Changes

We may update these terms. The version on this page, with the date at the top, is the one that applies.
