Participant settings control how survey participants and their responses are managed — anonymity, resuming, repeated responses, self-registration, and participant emails.
Every option here is an On/Off toggle (plus one number field), and the panel autosaves — there is no Save button; a "Saved at" time confirms each change.
When On, responses cannot be linked to participant information: the response and the participant record are stored with no connection, and completion dates are set to 1980-01-01 so answers cannot be correlated with server logs either. Use this for sensitive topics where you must be able to tell participants their answers are truly anonymous.
This setting locks when you activate the survey — decide before going live. Once responses are anonymized, no one (including support) can link them back to people.
When On, invited participants can close the survey and return later through their personal link — their previous answers are still in place and they continue where they left off, without needing the "Resume later" function. Use it for long surveys with invited participants. It requires a survey with a participant list, and does not work together with anonymized responses (the answer must be linkable to the participant to be restored).
When On, a participant who has already submitted can open their invitation link again. Depending on the persistence and anonymity settings above, this either lets them edit their existing response or submit a new one. Leave it Off for the classic "each invitee answers exactly once" setup.
When On, visitors who open your survey link without an access code are offered a registration form instead of being turned away. They enter their name and email address, are added to the survey's participant table, and receive an invitation email with their own access code. Use it when you want a closed-access survey (one response per person) but don't have the participant list up front.
When On, the emails sent to participants — invitations, reminders, confirmations — are sent as HTML rather than plain text, and you can format them (bold, links, images) in the email templates. If your participants' mail systems only accept plain text, leave it off.
When On, participants from the participant table receive a confirmation email after submitting the survey. The text comes from the Confirmation tab of your email templates.
The length of the generated access codes. The default is 15 characters, the maximum is 35. Enter any value above 5 to customize; a value of 5 or lower reverts to the default of 15. Longer codes are harder to guess — only shorten them if participants must type codes in manually.
