Your data
The hub keeps your account, goals, courses and progress so they can follow you between devices. You can download everything held about you, or delete it all, from any client. The privacy note says exactly what is kept.
Shared courses
A course you share stays in the marketplace if you later leave; that is the one thing deletion does not take. The terms say so in one sentence.
