Terms of use
Last updated 2 September 2026.
What this is
Step Solver is a maths practice app. It is offered as it is, free of charge while it is in beta, for personal and family use.
Your account
You sign in with a Google account and you are responsible for it. One account is meant for one family. Please do not share your sign-in, and do not use the app to redistribute the lessons.
The questions
The competition questions are the property of their authors and organisers. They are transcribed here for teaching, with the working and the explanations written by us. The scanned papers themselves are not published on this site. If you hold the rights to a paper and want a question removed, write to us and it will be.
What we do not promise
We work hard to get every answer right and we say how each one was checked, but this is a teaching aid, not an official answer key. Do not rely on it as the last word in a competition or an assessment. The service may be unavailable, may change, and may end.
Ending it
You may stop using the app and disconnect it from your Google account at any time. We may suspend an account that is being used to attack the service or to redistribute the lessons.
Law
These terms are governed by the law of Thailand.
