In signing up to take this course, you agree to the Terms of Service which governs this course. 

By purchasing this course, you will have access to this course as long as I support it. (Hence "Lifetime Access" means for the lifetime of course, not the lifetime of the student.) I promise to provide access to future versions of the course to all students who bought the first edition in April 2019. However, I do reserve the right to no longer support or host the course. At which point, I will notify all students and may suspend access to course materials.
