# Interview settings

> The Survey tab of campaign settings: access, advanced statistics, anti-spam and per-campaign permissions.

This is where you decide how the interview behaves as a whole: whether it's reachable, how it collects data and who on your team can work on it. Individual questions aren't part of it — you configure those in the Builder.

Campaign settings open as a single modal with four tabs: **Survey · Webhook · Quota · Variables**. This page covers the Survey tab; the other three have their own pages.

## The Survey tab

Three switches, and nothing else.

<AccordionGroup>
  <Accordion title="Enable Survey" icon="circle-play">
    Lets participants access and complete the interview. If you turn it off, the interview is not reachable by respondents.

    Use it to pause collection without touching distribution. See [Publishing your study](/en/distribute/publishing) for the full go-live flow.
  </Accordion>

  <Accordion title="Advanced Statistics Mode" icon="sigma">
    Collects extra information and structures the dataset for professional statistical analysis.

    Turn it on before you launch: several features don't appear in the interface while this mode is off. See [Advanced statistics mode](/en/advanced/advanced-statistics).
  </Accordion>

  <Accordion title="Limit Spam" icon="shield">
    Prevents multiple submissions from the same device, reducing duplicate or spam responses.

    You need it when you don't control who answers the interview: studies open to the public, distribution via public link, data collection without a controlled panel.
  </Accordion>
</AccordionGroup>

## Access Management

Below the switches, **Access Management → Manage Users** sets permissions for this campaign alone: who can open it and work on it, regardless of the rest of the workspace. See [Campaign collaboration](/en/workspace/collaboration).

## The other three tabs

* **Webhook** — send every new response to your system in real time. See [Webhook configuration](/en/webhooks/configuration).
* **Quota** — limit how many people can complete the interview based on their answers. See [Quotas](/en/distribute/quotas).
* **Variables** — the named values you carry along with each respondent. See [Context variables](/en/logic/variables).
