I am the founder of Catholic Online Dating UK. Safety and privacy is a fundamental part of what we do.
Firstly, unlike many other dating websites we do not use our users for advertising purposes: aside from user blogs, all content and profiles are only visible to registered members. New members need manual approval before they can contact existing members. Unlike location-based dating applications, users provide as much or as little location information as they like. Messages are kept for at most 60 days before being deleted for increased security.
