The GDPR, or General Data Protection Regulation, is the new law that grants data security and privacy for all EU citizens.
According to the new GDPR legislation, you can't collect customers' data (name, email, phone etc.) without their permission. With HelpCrunch, you can ask for their permission right when visitors and customers are about to leave you a chat message.
