There is no easy way to cancel the subscription except via an email which they don't respond to for over 3 days. This company claims to work with doctors and to keep your information secure. Don't take my word for it, try to cancel via the site, you will hit a complete dead end until you give them photos of yourself. I submitted fake ones, and was able to unsubscribe. Be careful, this is not an ethical company. A good company makes it easy to leave it. This one does not.
