What these terms cover. Every recorded course sold on ngs101.com. Live workshops have their own terms, stated on each workshop’s page.
What you are buying. A one-time purchase of one recorded course, at the price shown on its course page and at checkout. Each course page lists exactly what that course contains, such as the videos, slides, scripts, example data, handouts and workbooks, and the take-home pipeline. There is no subscription and nothing renews.
All sales are final. Every file is downloadable, the videos included. Once a file is on your computer there is no way to return it, so there are no refunds and no partial refunds. That is exactly why each course page shows you what’s inside before you buy, including a free walkthrough. Please watch it.
How you get in. Buying creates an account on ngs101.com, or adds the course to the account you already have. Sign in with your email address and password to reach your downloads page. The links on that page are generated fresh each time it loads and stop working after a few hours by design; reload the page and you get new ones. There is no limit on how many times you download.
How long access lasts. Your downloads page stays available for at least twelve months from the date of purchase. The files you have already downloaded are yours permanently and do not depend on this site staying online — the example data comes with the course, so everything runs with no internet connection at all.
What you may do with the files. Use them for your own work and your own research, on as many of your own computers as you like, for as long as you like.
What you may not do. Share, resell, republish or redistribute the files or any part of them; place them on a shared drive, repository or course platform that other people can reach; or use them to deliver a paid course of your own. One purchase covers one person. For a lab or a teaching group, ask about a group arrangement.
Live workshop credit. Where a recorded course has a live workshop on the same topic, the full price you paid for the recorded course comes off the price of that workshop, whenever you decide to take it. There is no deadline. Reply to your purchase email to request the code; it can be used once.
Support. Recorded courses are self-serve, deliberately. Everything you need is in the files, and the written walkthrough for every step is on ngs101.com. A recorded course does not include email support, office hours or a forum. The live workshops are where I answer your questions on your own data.
Payment. Payment is processed by Stripe. NGS101 does not see or store your card details.
Questions about your purchase. Write to lei.guo@ngs101.com. This is for billing and enrolment questions only; the courses themselves are self-serve.
