How Participant Data is Collected

When users engage with DecenTrialz, we collect only the information necessary to support matching, study enrollment, and communication.

Types of Data Collected

• Personal details: name, age, gender, contact information
• Health-related inputs: condition, symptoms, medical history
• Study-specific inputs: location preferences, availability, trial status
• System interactions: survey responses, task completion, engagement history

Data Collection Methods

• Direct input by participants through forms and dashboards
• Data collection includes pre-screening health questionnaires to confirm eligibility
• Passive system data (e.g., platform usage for reminders and alerts)

Key Note: No sensitive health data is collected without explicit participant consent. Consent is obtained through transparent disclosures and IRB-approved consent forms.
