ChatSecure will always remain free of charge to ensure that everyone in the world has unrestricted access to privacy technology. The project is mostly funded by very generous grants, so there is no need to "monetize" the project.

The amount of money we could make by selling the app directly to users wouldn't even begin to support the actual cost of producing and supporting the software.

I know it's not necessarily an accurate selling value of the application, but you could just charge $.99. That would probably head off a lot of the recompilers by making it not-so-worth-it. You never know, though. People will try anything.
