SurveyCircle is based on honest mutual support.

To uphold this principle, we have established simple rules that everyone must follow. To protect the community, we use quality assurance systems that help us identify rule violations.

Rule #1: Fill out all questionnaires truthfully and conscientiously (i.e. take your time to fully comprehend questions and possible answers, to read scenario descriptions, to fill in text fields, etc.).

Rule #2: Participate in studies only when you meet the participation criteria.

Rule #3: Redeem Survey Codes only if you have earned them in compliance with the rules.

Rule #4: Redeem Survey Codes directly after completing a study.

Rule #5: Rate the quality of studies objectively and in a differentiated way.

Rule #6: Do not share Survey Codes with others.

Rule #7: Do not use multiple user accounts.

Rule #8: Do not let anyone use your user account to participate in studies.

Rule #9: Do not use rule violations by others to your advantage.
