Privacy & data storage
For its interface, gRDV Messages stores messages, contacts, conversations, account settings and encrypted attachments in the WordPress installation. The original mailboxes remain with the configured email provider. Apart from these email servers, Free does not contact any gRDV service.
Pro also uses the gRDV licence and update service. When web push is enabled, encrypted push notifications are transported through the push service selected by the browser or operating system. With optional open tracking, the recipient’s email client calls a tracking URL on the WordPress installation.
