Terms

Last updated October 22, 2026

These are the rules for using Lemmory. By making an account, you agree to them.

Accounts

  • Give your real name, keep your password to yourself, and use only your own account.
  • Teachers are responsible for the classes they create and for inviting only their own students.
  • You can delete your account at any time from your account page.

Plans and trials

Every plan starts with a 14-day free trial. The prices are on the pricing page. When a trial ends without a paid plan, reviewing pauses until one starts; nothing is deleted. Students in a class on a paid plan never pay.

Using it fairly

  • Don't try to get into accounts or classes that aren't yours, or to get around trial limits.
  • Don't send automated traffic or try to break or overload the site.
  • We may close an account that does these things.

The content

The formulas, problems and explanations are written for Lemmory, and are for use in Lemmory. We check every answer, but if you find a mistake, please email us. Lemmory isn't affiliated with the MAA, AoPS, or any contest.

No guarantees

We work to keep Lemmory running and correct, but it's provided as is, without a promise that it will always be available or free of errors, or that using it will raise anyone's scores.

Changes and questions

If these terms change, we'll update this page and the date at the top. Questions go to ryancho823@gmail.com. How we handle information is on the privacy page.
