Questions people actually ask
How accurate are these tests?
They have not been validated. Chunyang wrote the items from the published structure of each framework. There is no norm group and no reliability study of these specific questions. The Big Five is the framework with the research behind it. The 16-type test, the Enneagram, and DISC are weaker, and each test page says so before you start. A result describes your answers that day. Scoring rules and the papers are on the methodology page.
Is my data secure?
Without an account, your answers and the History list stay in this browser. Individual answers are not uploaded. The site does store anonymous quiz analytics in Supabase (Singapore): a random guest id with no email, which test you started, how far you got, and the scores and result code if you finish. If you sign in, the scores and result code you save are stored with your account so you can open them on another device, and you can delete them from History. Nothing is sold.
Can I retake a test?
Yes. Take any test as often as you want. Guest results stay in this browser so you can compare sittings. A letter that won by one or two points is the one that usually changes.
