I like the idea but why would I pay to trust you with my most inner thoughts?

Would tend to agree. Interesting concept but unless it's all encrypted, I wouldn't trust this at all.

Especially when you can't see the product and the readme has placeholders left over from ChatGPT

This is a key question. I'm still reflecting about it. TLDR. Is a sensitive subject that needs to be well thought.

So when I journal manually in a book, I trust that I'm going to be the only person reading it. When I journal digitally is a bit different, in this case I trust the app because I made it myself for my own needs, but I wonder how to transmit that trust to the user. Encryption can be the way to go, I know there are different ways of implementing that, maybe optional encription in some places or some texts, but then if the users loosses the password then that content is gone forever, and also there could be say if we want to add some functionality to work with those pieces of text, if it's encrypted the backend would not be able to do things like filtering and so on...
