Terms

yogi builds a daily set of practice questions from your school’s own course materials, and gives you a place to answer them. It is study material. It is not medical advice, it is not a substitute for your course, and it is not your school’s product — we are not affiliated with, endorsed by, or speaking for your school or your faculty.

Questions are written by software and reviewed by software before they reach you. We work hard at that review, and we still expect to be wrong sometimes. Every question has a flag button; use it, and we will take the question down and look at it.

One account, one person. Do not share your sign-in — a shared account produces a worse tutor for both of you, because the whole system is built around what one person has and has not proved.

$99 for the rest of the block, paid once. The same price for everyone, from the first day. There is no monthly price, no discounts, no student tier, no annual deal and no coupon codes — if you are offered one, it did not come from us.

Yogi is free through October 19, 2026 — the first six weeks of Keystone Fundamentals, counted from the day the block starts. It is the same date for everyone, whoever you are and whenever you joined. After that, it is $99 once for the rest of the block. Payments are handled by Stripe; we never see or store your card details.

You can stop whenever you like. Nothing you have already done disappears, and your Review page stays readable.

If a payment fails, new sets pause and Review stays readable. Pay again and sets resume the next morning.

The questions, explanations and citations we show you are ours, and you may use them to study, alone or with classmates. Please do not republish them, sell them, or feed them into another question bank. Our position on how these questions relate to your school’s materials is written out on the copyright page.

Scraping the bank, sharing an account, reselling access, or trying to get at other students’ data. We will close an account for any of those.

You can leave whenever you like, and you can ask us to delete your account and everything in it; we will, and it will be gone. We can end or suspend an account for the reasons above, or if we stop running the service — in which case we will tell you before we do. Any refund is considered on an individual basis.

If we change anything here that matters, we will email you before it takes effect. Carrying on using yogi after that is how you accept the new version.

These terms are between you and Yogi, and they are read under the law of the Commonwealth of Pennsylvania. Questions, complaints and anything that needs a human: the address your invitation came from.
