Relay holds your most personal details, so you deserve total clarity about who makes it, how to verify it, and what we can (and can never) see.
Relay is built and published by the team at relaykeyboard.com, reachable any time at info@relaykeyboard.com. Relay for Windows is published on the Microsoft Store (product ID 9NN8GW2XX2ZW), and the Mac downloads are served only from relaykeyboard.com. If you got a Relay installer from any other source, don't run it.
The Microsoft Store verifies the Windows app for you. The old direct Windows download from this site has been retired; install Relay for Windows from the Microsoft Store. The Mac downloads have published SHA-256 checksums at /downloads/checksums.txt. To check yours, open Terminal and run:
shasum -a 256 ~/Downloads/Relay-AppleSilicon.dmg
If the value matches the published one, your download is byte-for-byte the file we released.
Install Relay for Windows from the Microsoft Store: Store apps are checked and signed by Microsoft, so there's no SmartScreen notice, and the Store keeps Relay updated. The Microsoft Store is the only place we offer Relay for Windows.
Your vault is encrypted on your device, with face or fingerprint lock when your phone has a screen lock set. We never hold the key, so we can't read your vault. For the plain-language version, see How Relay protects you; the full detail lives in our Privacy & Security page.
