Use Lucid to sharpen your thinking. Don't do anything illegal with it. That's pretty much it.
Lucid provides educational content about cognitive biases, logical fallacies, mental models, and psychological phenomena. Each track runs for a set number of days, delivering one entry per day.
The content is for educational purposes only. I'm not responsible for any decisions you make based on what you learn here. You're a grown-up. Think for yourself.
The app design, text, and content are mine. Don't copy or redistribute them without permission.
I might update these terms occasionally. If I do, the new terms will be reflected here.
