WS Form can help make your forms and website GDPR-compliant. You can add consent checkboxes to explain why data is being collected and request consent for using the information provided.
WS Form also supports GDPR request workflows in WordPress. It integrates with the WordPress personal data tools so you can create forms for data erasure requests and data export requests.
