Yep! Both free and paid. We have some pretty serious security principles. I'm the creator, so if you have any questions let me know. All of my work I do is open-source -- and we also have a public Slack channel and Twitter where I post updates. The paid plans are for if you don't want to use free DNS-based forwarding setup, a small fee for unlimited domains/aliases/etc to help me maintain server costs (see the FAQ). I may make Enhanced Protection available for free at some point in the future, but I built it this way at first because the website used to be a simple wiki, and I used the DNS-based setup myself 2 years ago.
