Terms

You are buying a personal licence to read the book, and if you subscribe, The Lab. You may read it on as many of your own devices as you like, quote it with a link, and apply everything in it to your own work or your clients'. You may not republish substantial parts of it, share your account, or resell it. Buying the book includes every future edition. Cancelling a Lab subscription does not remove the book. That was a purchase, not a rental.
