From the developer:
CyberCat is an intuitive VPN for macOS, iPhone and iPad that lets you access the Internet the way it was intended—private, secure, and unrestricted. Also, the app selectively lasers all ad networks and trackers on third-party websites, so you can enjoy an ad-free Internet experience.
