Why do I keep…

This tool does not diagnose medical or mental-health conditions and does not measure your dopamine level. Nothing you enter leaves your device. If something is affecting your daily life, find the right kind of help.

How this works

Your answers pick from explanations written in advance by the editorial team and drawn from our graded evidence pages. Nothing is generated on the fly, nothing is stored, and there is no score. Behaviour is shaped by habits, context, feelings and sleep — dopamine is part of the picture, rarely all of it.
