A few things worth knowing.

No. Open PairSend in your browser, start a session on one device, and join from the other. There is no account setup or app installation required to send files and text.

Starting a session creates a pairing code and QR. On the second device, open PairSend and enter that code, or scan the QR shown in the session. Keep the code private and wait for both devices to connect before sending.

Yes. PairSend is a live handoff between two browsers. Keep both tabs open until the transfer finishes. It does not create a stored download link for someone to use later.

PairSend does not store your file contents on its servers. Files and text are encrypted in your browser and sent during the live session. The service keeps temporary connection information to help the browsers connect.

No. Session expiry ends access through PairSend; it does not delete original files or copies that someone has downloaded. Save received files before the session expires if you want to keep them.

No. Every plan uses the same end-to-end encryption. Paid plans add saved devices and higher daily sending limits, with the same security boundaries as the free plan.

Check that both devices are online and keep their browser tabs open, especially on a phone. Try again with a new session if the code has expired. If a network blocks the direct connection, try another network; a paid plan does not guarantee connectivity.

A short reconnect window can let you return on the same device before the session expires. It does not extend the session’s expiry. If the window or session has ended, start a new session.

On a paid plan, you can save a trusted device after a successful live connection. For the next handoff, send a request and approve it on the other device instead of scanning again. Keep PairSend open in both browsers to receive the request. Each accepted request starts a fresh session.

Pro adds up to 5 saved devices, 25 sends per day, and 25 GB per day. Business adds up to 20 saved devices, 100 sends per day, and 250 GB per day. Standard includes 3 sends and 1 GB per day. All plans share the same encryption.

Paid access is saved locally in the browser where you activate it. It is not a traditional account that automatically follows you to every device. Clearing browser data can remove that access, and purchase recovery is still being finalized.
