Terms of Service
Last updated: October 13, 2026
Euclid Engine ("Euclid", "we") is a worksheet-generation tool for teachers, operated by Trystan Oliver (TryOlive) at euclidengine.tech. By creating an account or using the service, you agree to these terms.
Accounts
Accounts are for individual teachers and educators. You sign in with your email address via a one-time link; you are responsible for activity under your account. Euclid accounts are not for students, and you must not enter student names, student records, or other student data into the service — the service is designed to work without it.
Plans and billing
Free accounts may generate a limited number of watermarked exports per month from a limited topic set. Pro subscriptions ($9/month or $79/year) unlock unlimited generation, all topics, answer keys, an un-watermarked export, the saved library, and the IEP accommodation features. Subscriptions renew automatically until cancelled; you can cancel any time from the billing portal, and cancellation takes effect at the end of the current paid period. School licenses ($299/year, up to 10 named teacher accounts) are arranged by contacting us.
Your worksheets
Worksheets and notes you generate are yours to print, copy, and use with your own students, in your own classroom, without restriction. You may not resell generated worksheets as standalone products or use the service to build a competing worksheet library for redistribution.
Acceptable use
Don't abuse the service (automated bulk generation outside normal classroom use, attempts to bypass plan limits, or interference with the service). We may suspend accounts that do.
Service and liability
The service is provided "as is". Generated problems are produced by verified algorithms, but you are responsible for reviewing materials before classroom use. To the extent permitted by law, our liability is limited to the amounts you paid us in the preceding 12 months.
Changes and contact
We may update these terms; material changes will be announced on this page with a new date. Questions: support@euclidengine.tech.
