Ensuring GDPR compliance in LimeSurvey starts with proper configuration and awareness of data handling practices. Administrators should enable secure connections (HTTPS), minimize collection of personally identifiable information, and use anonymization features when possible. Clearly informing participants about data use through consent forms is essential. Access control should be restricted to authorized users, with strong passwords and audit logs enabled. Regular updates of LimeSurvey and server software also play a key role. Together, these measures help maintain GDPR compliance effectively.
