Yes, MetaSlider is GDPR complaint.
MetaSlider does not access or extract any user data from WordPress. Also, MetaSlider does not access any visitor data from your website.
MetaSlider uses the Appsero SDK to collect non-sensitive diagnostic data upon a user’s confirmation. This data helps us to troubleshoot problems faster & make product improvements. MetaSlider only collects this diagnostic data when a user allows it via a notice in WP Admin or MetaSlider settings.
You do not have to agree to send non-sensitive diagnostic data to AppSero. MetaSlider will function perfectly without that agreement.
