Common questions
How is the free tier limited?
Free covers all 10 phases of Make Math Mine (every lesson, no daily limit) plus Free Practice in preset interests with no daily caps. The AI tutor and on-demand Teach Me This are part of Plus.
Does Plus have usage limits?
Lessons and Free Practice have none. The AI features come with generous monthly allowances, set well above what anyone working through math by hand will reach. They’re there to keep scripts and bots in check, not learners.
Is there a free trial of Plus?
No separate trial. The free tier isthe trial. Free gives you all ten phases, every lesson with no daily limit, and Free Practice in our preset interests. Plus adds the AI tutor, Teach Me This uploads, Free Practice on any interest you describe, and deeper personalization based on what you’ve worked on. Subscribe whenever those start to feel worth it.
Can I cancel anytime?
Yes. Cancel from your account at any time. Your Plus access continues through the end of the period you've already paid for, and you won't be charged again.
Do you offer refunds?
All sales are final. We don't refund subscription fees. The Free tier gives you full access to all ten phases with no daily caps, so you can try the experience before subscribing. If you were billed in error (duplicate charge, accidental sign-up within 24 hours, or a billing system bug), email support@nummmbers.com and we'll fix it.
What happens to my work if I cancel?
Nothing changes. Your progress, mastered phases, custom interests, and anything you've written stays on your account. You just lose tutor access and the higher Teach Me This limit until you resubscribe.
Is billing per account or per person?
Per account. One Nummmbers account is meant for one learner. Sharing an account isn't supported, and a household with two learners should use two accounts.
Who handles payment?
Stripe processes payments and acts as the merchant of record. Card details never touch our servers. Receipts arrive by email.
