End-to-end encrypted transfer

Only for Mac

Free · In‑App Purchases

Mac

Drag files straight from Finder. Send files and text between your devices, end-to-end encrypted—direct on your network or as ciphertext the relay cannot read. Relayium makes it simple to send files, folders, and text between your Mac and other devices, with end-to-end encryption built in. Drag files or folders directly from Finder, or use the built-in file picker. SEND NEARBY Discover Relayium devices on your local network and transfer files or text directly between them. Nearby transfers do not require a cloud upload. CONNECT ACROSS NETWORKS Create a short pairing code to connect devices that are not on the same network. Drag files or folders from Finder, review the selected content, and explicitly confirm before sending. Your content remains end-to-end encrypted. Relayium’s relay infrastructure carries ciphertext that it cannot decrypt. DEVICE INBOX Exchange files, folders, and text with your trusted Macs in a private conversation. Drag content directly from Finder, review sent and received items in one timeline, continue the conversation from the same screen, and remove individual items or an entire conversation locally whenever you choose. SECURE DOWNLOAD LINKS Encrypt files before uploading them and share a download link for later access. Relayium stores encrypted data without the key required to read your files. BUILT FOR PRIVACY • End-to-end encrypted transfers • File integrity verification • Optional verification codes for comparing endpoints • No advertising or cross-app tracking • Open-source implementation Nearby transfers can be used without signing in.
