About

Why only published scales

Many online "personality quizzes" are made up, with no evidence of reliability or validity. Every scale here is backed by published research, and the items, scoring and cut-offs match the original.

Each result page lists the original source so you can check it.

Where your data goes

Your answers are scored in your browser. What you chose for each item is never uploaded.

When you finish a test, the site records one anonymous tally: which test, which band, which day. That powers "How others scored". No IP addresses, no ad tracking.

Signing in is optional and uses only your email, no password. Tests you take while signed in leave an entry under Account (score and date only), which you can clear at any time. Payments are handled by WeChat Pay or Waffo; this site never sees or stores card details.

A result link contains only your score, not your answers. Before sharing it, consider whether you are comfortable with the other person seeing that score.

Purchases and refunds

In-depth reports and membership are digital content, available as soon as you pay. A single report is yours to keep; membership lasts a year, renewals extend from the end date, and nothing renews automatically.

If you paid but nothing unlocked, were charged twice, or bought the wrong thing, email yeschenxiang@gmail.com with the email you paid with and roughly when. Once checked, we refund you and remove the matching report or membership.

Results and support information for mood and clinical screening tests are always free and never part of paid content.

How to read your result

Self-report scales reflect how you have felt recently, at the moment you answered, and change with your circumstances. They can flag signals worth attention but do not replace a diagnosis by a doctor or counselor.

If mood scales (depression, anxiety, well-being) stay concerning for more than two weeks, consider talking to a professional.
