Glossia Relay Network

Reference client · Windows, macOS and Linux

Glossia for desktop

A companion client for computers, linked to your phone. It keeps no keys the phone does not know about, and can be unlinked from the phone at any time.

What it does

  • Linked to your phone by scanning a code; up to four computers per person
  • Decrypts attachments in memory and writes them to disk only when you save them
  • Locks after a period of inactivity
  • Unlinking from the phone removes every key from the computer at its next connection

In earlier versions the desktop client kept decrypted attachments in a temporary folder until it was closed. This was reported in the 2026 audit as GL4-M2 and fixed before release.

Where it comes from

Instructions for installing the desktop client appear in the mobile app when you choose to link a computer. Frothly does not offer it for download on this site.
