Terms of Use
Last updated 1 September 2026
By creating an account and using Prochoro, you agree to these terms.
What Prochoro is
A free study app that turns AP course material into a map of practice stops. It is a revision aid, not a course, and not a substitute for your class, your textbook, or official College Board materials.
About the questions
Every question in Prochoro is original practice material written against each course's published unit outline. None of it is real exam content, and none of it is reproduced from the College Board. Practising here does not guarantee any particular score.
Your account
- You must be 13 or older to create an account.
- Keep your sign-in details to yourself; you are responsible for activity on your account.
- You can delete your account at any time from Profile — it removes everything immediately.
- We may suspend accounts used to attack, abuse, or disrupt the service.
Acceptable use
Don't attempt to break into the service, extract other people's data, scrape the question bank in bulk, or redistribute its content as your own. Ordinary studying — including screenshotting a question you got wrong — is entirely fine.
Availability
Prochoro is offered as-is and free of charge. We do not promise it will always be available, and features may change or be removed. If the service is ever discontinued, we will give reasonable notice so you can note down anything you want to keep.
Your content
Your progress belongs to you. The app itself — its code, artwork, and question bank — remains ours.
Liability
To the extent permitted by law, Prochoro is provided without warranties, and we are not liable for exam results, lost progress, or other indirect losses arising from using it. Nothing here limits liability that cannot be limited by law.
Trademarks
AP and Advanced Placement are registered trademarks of the College Board. Prochoro is independent and is not affiliated with, endorsed by, or approved by the College Board.
