Anonymous Responses & Source Tracking

ResponseDock separates respondent identity from source attribution. A survey can be completely anonymous while still tracking where responses come from.

Anonymity Modes

Mode	What is stored
`anonymous`	No name, email, external user ID, or platform user ID stored
`identified`	Respondent identity linked to the response (requires SDK `identify()` call)

Source Tracking Modes

Mode	Stored fields
`none`	No source data stored
`basic`	Channel, UTM source, UTM campaign
`full`	Channel, all UTM params, referrer, page URL, event/context ID, device type, approximate region

Respondent Messaging

The survey renderer shows respondents what data is collected:

Your answers are anonymous, but this survey may collect source information such as campaign, page, or event.

For identified surveys:

Your answers are linked to your account.

Follow-up Email Collection

The optional follow-up email block collects email consent separately from survey answers. By default, follow-up contacts are stored in a separate table and not linked to the response. You can enable linking in the survey's follow-up config.

// Survey follow-up config
{
  "followUpConfig": {
    "enabled": true,
    "title": "Stay informed",
    "description": "Leave your email to receive a summary of results.",
    "consentLabel": "I agree to be contacted about survey results",
    "privacyNote": "Your email will not be linked to your responses.",
    "linkToResponse": false,
    "purpose": "results"
  }
}

Configuring via API

PATCH /surveys/:id
{
  "anonymityMode": "anonymous",
  "sourceTrackingMode": "basic"
}

GDPR & Data Export

Respondents can request deletion or export of their data. If a survey is anonymous, individual responses cannot be attributed to a person, so there is nothing to export. For identified surveys, use DELETE /responses/:id to fulfill deletion requests.
