How do I ensure popups are GDPR compliant?

To make your popups GDPR compliant, focus on transparency and user control. Start by explaining exactly what data you're collecting and why, in plain language. Always ask for consent using clear “accept” and “reject” options and don’t assume consent with pre-checked boxes. Let users easily change their preferences or opt out anytime. And don’t forget a visible link to your privacy policy so they can dive into the details if they want to.
