Terms
Rho1 Inc. — Last updated: 2026-07-28
These terms cover the Rho1 Prep apps — PMP Prep on iOS and the web app at pmp.rho1.ai. Our free flashcard apps have no accounts and no subscription; nothing about billing below applies to them.
What the service is
Study tools for professional certification exams: flashcards, quizzes, timed practice, mock exams and progress tracking.
We are not affiliated with, endorsed by, or certified by any certification body, including the Project Management Institute. PMP is a registered mark of its owner. We prepare you for an exam; we do not administer it, and nothing here is a promise that you will pass it.
Your account
You sign in with Apple. You are responsible for keeping access to your Apple ID secure. You need to be old enough to enter a contract where you live, and these apps are built for adults preparing for professional exams.
You can delete your account at any time from Settings in the app.
Free and paid features
Flashcards and the diagnostic quiz are free. Practice quizzes, timed tests, full mock exams and the insights dashboard require an active subscription. One subscription covers both iOS and the web when you are signed in to the same account.
Billing, cancelling and refunds
Subscriptions are sold and billed through the Apple App Store, and Apple is the merchant of record. Apple charges your Apple ID payment method, and the subscription renews automatically until you cancel.
Manage or cancel through your Apple ID — on iOS, Settings → [your name] → Subscriptions. Cancel at least 24 hours before the period ends to avoid the next charge; you keep paid features until the current period runs out.
Refunds are handled by Apple, not by us — we are not able to issue them for App Store purchases. Request one at reportaproblem.apple.com.
Acceptable use
The question banks, explanations and other study content are ours. Use them to study. Do not redistribute, resell, scrape or republish them, and do not share your account so others can use a subscription they have not bought.
Changes and ending the service
We may change these terms; if we do, we will update this page and the date at the top. We may suspend an account that is being used in breach of the acceptable-use section above.
Privacy
What we collect and why is set out at rho1.ai/privacy.

These are interim terms, published so that the links in our apps resolve to something accurate. A fuller set is being prepared and will replace them here.
