Ghost Chat is free and open source. There are no premium tiers, subscriptions, or ads.

Windows: "Windows protected your PC"

The first time you launch Ghost Chat, Windows Defender SmartScreen may show a "Windows protected your PC" message. This appears because Ghost Chat is not signed with a Microsoft certificate.

1. Click More info.
2. Click Run anyway.

You only need to do this once.

macOS: "cannot be opened because the developer cannot be verified"

This happens because Ghost Chat is not code-signed with an Apple developer certificate. To allow it:

1. Open Finder and locate Ghost Chat.
2. Control+Click (right-click) the app.
3. Select Open.
4. Click Open in the dialog.

macOS remembers your choice, so future launches open normally.

macOS: "Ghost Chat is damaged and can't be opened"

This is the same code-signing limitation as above, surfaced differently by Gatekeeper. The quickest fix is to clear the quarantine attribute. Open Terminal and run:

xattr -rd com.apple.quarantine /Applications/ghost-chat.app

Then launch the app normally.
