Before you start

  • Your answers are saved so we can score them and show your results.
  • Only you can see them, in this browser on this device.
  • We keep them for up to 180 days. You can delete them at any time from your results page.
  • If you choose an AI report, your computed scores (never your individual answers) are sent to Anthropic, our AI provider in the USA, to write it.
  • No one reviews your answers in real time. If you need help now, use urgent support, not a questionnaire.
  • You can stop at any time. Results are educational — never a diagnosis.
