Who Uses Ciphar

Ciphar is built for professionals who need a private channel right now, with someone they may never speak to again, without any account, install, or contact-info exchange. Below are the main use cases. Each links to a dedicated page describing the threat model and workflow for that audience.

Use cases

• Journalists & their sources — anonymous tips, source protection, ephemeral interviews.
• Lawyers & clients — privileged communication when a regular messenger is the wrong fit.
• Healthcare professionals — sensitive coordination without a permanent message trail (with the necessary regulatory caveats).
• Security researchers — vulnerability coordination, responsible disclosure, off-the-record working sessions.

What these audiences have in common

• The conversation is sensitive but short-lived.
• Both sides are reluctant to exchange phone numbers, emails, or persistent identifiers.
• A native-app install would create friction or visibility neither party wants.
• A permanent message archive is itself a liability.

If your situation does not fit one of these neatly, that is fine — Ciphar is a general-purpose encrypted room. Forge a channel and try it. Or read about how it works.
