Terms of Service
Last updated: 12 September 2026
Fair use
Use doubtZero to understand, practice and prepare — not to copy answers blindly during tests or submit work that is not yours. The tutor is meant to be a learning partner, so make sure you actually understand the solution before moving on.
The tutor's role
Answers are generated by an AI tutor to help you learn. They are a study aid and should be checked against your textbook, teacher and official syllabus. They are not official board advice.
Account responsibility
If you create an account, keep your login details safe and respect other learners. You are responsible for the questions you ask and the way you use the answers.
Availability
We aim to keep the service available 24/7, but temporary downtime for upgrades is possible. We are not liable for learning outcomes that depend on third-party systems.
Changes
We may update these terms as the product grows. Continued use of doubtZero after updates means you accept the revised terms.
