Terms of use
Last updated October 20, 2026
ROI Prep (roiprep.com) is run by BRIset Analytics. By creating an account or buying a course you agree to these terms. Questions: cmorisset@brisetdata.com.
What you get
Buying a course ($5 CAD, one-time) opens every ROI Prep guide for that course: the lessons, labs, practice questions and flashcards, including guides and problems added while your access lasts. Only courses with at least one live guide are for sale.
How long access lasts
A purchase opens the course for 120 days from the day you buy it, enough for a full term. Access from an access code lasts as long as that code says. Your saved progress lives in your own browser, not on your account.
Your account
- One person per account. Don't share your password, your account or the guides.
- Use an email you can open: it is how you sign in, reset your password and receive receipts.
- We can close an account that is shared or used to copy the guides, and refund what is left of its purchase.
Study aid only
Study aid only. Not for use on graded assignments, quizzes or exams. ROI Prep teaches the concepts with its own original examples. Follow your course's academic integrity rules. ROI Prep is an independent study tool, not affiliated with or endorsed by the University of Calgary; course codes are used only to identify courses. Exam format, weight and allowed aids depend on your instructor: check your own course outline.
Payments and refunds
Payments are processed by Stripe; card details go to Stripe and never reach us. Prices are in Canadian dollars. No GST is charged: BRIset Analytics is a small supplier. Full refund within 14 days: see Refunds.
Mistakes and changes
We check the guides carefully, but they can contain errors; tell us with the Feedback button and we fix them. ROI Prep is provided as is, and our responsibility for any problem is limited to what you paid for the course. We may update these terms; the date at the top shows the last change. These terms are governed by the laws of Alberta, Canada.
