About CoyIM
CoyIM is a standalone chat client for the XMPP protocol, available for Windows, Linux and macOS. It is designed to work securely with default settings, requiring no plugins, extensions or configuration changes to enable its security features. Built-in support covers Tor, OTR and TLS: Tor is described as making internet connections anonymous, OTR enables end-to-end encryption of communication, and TLS adds encryption for communication with chat servers.
The project page carries a prominent notice that the software has not yet been audited and should not be used for anything sensitive. The current download listed is version 0.4.1, with SHA256 checksums published for the Windows, macOS and Linux packages, and installation instructions available on the site. Pricing is not stated.
