Some learners want the convenience of account history; others want to complete a quiz without adding that attempt to their QuizMachine account. A paid-plan quiz owner can support both preferences.
Enable the choice in quiz settings
Open Configure, enable the signed-in respondent result choice, and save settings. The option is available on paid plans and stops being offered if the owner's effective subscription no longer includes it.
A clear choice before the questions
Eligible signed-in respondents see a switch before the quiz content. Saving to the account is on by default for backward compatibility. Turning it off leaves the completed response out of their account history.
What the privacy choice does—and does not do
The choice removes the account link; it does not delete the trainer-owned response. The trainer still receives the attempt for grading and reporting, and existing payment, retake, quota, and abuse-prevention rules continue to apply. Anonymous attempts are unchanged.
