Hello Harmony,
This is my first post here, but I am pretty good with words and concepts, so I'll take a stab or two... though it isn't easy with such limited info
"Secrets" is too commonly used, so is "revealing" ...
What about the concept of "eavesdropping", or "hidden peephole"... things that
uncover the truth, and if nothing else, force honesty?
Another approach would be using concepts that
imply honesty and truth, such as ...
"Proof", "transparent", "nude", "innocence", "untainted", "crystal clear", "origin", "principled", "open hearted"...
I guess the direction depends on the point of view being presented - uncovering the hidden and distorted truth vs. generously sharing sincere findings.
I hope these brief thoughts trigger some ideas for you.
All the best,
Tim
