I haven't looked into sandstorm yet because while I want to let people self-host if they want, it's not a priority for me. I'd rather use every free moment I have to improve the app, and because of the end-to-end encryption, the added security/privacy is negligible.
Rewording: using the word "applications" is a good idea, thanks. I need to see how to reword it exactly, but that may just be what I need.
I think journaling is an ok word for what its worth. You might add some actions that people can do with it however ie "you can replay and review any changes". Its a great feature its a question of lighting up their brain the right way.
I agree with your comment about protecting people, this is one of the reasons the server is also open source. Though I believe that if the need arises and demand is there, either myself or someone else will make it happen, and I already share all the tools (code) to make it happen, so people are protected.
