Terms and Conditions
Effective date: 19 July 2026 · Last updated: 19 July 2026
1. Provider and scope
The Numibo service — the website at numibo.com and the application at app.numibo.com — is provided by Amar Hidić s.p., a sole trader registered in Slovenia, Maroltova ulica 10, Ljubljana 1000, Slovenia, registration number 7501226000, VAT ID 42804213, email info@numibo.com (the "provider"). These terms apply to all users of the service. By creating an account you confirm that you have read and agree to these terms.
2. The service
Numibo generates math worksheets (addition, subtraction, multiplication and division exercises for grades 1–5), lets you solve them online and download them as PDFs. The features included in each plan are stated on the pricing page. Worksheet generation is intended for normal personal, family or teaching use; we may temporarily restrict generation that is automated, excessive or otherwise clearly beyond such normal use (fair use).
3. Eligibility and account
Accounts may only be created by adults (18+) — parents, guardians or teachers. Children use the exercises under the account holder's supervision. You must provide accurate information, keep your credentials safe and you are responsible for all activity on your account. One free trial is available per user.
4. Subscription and prices
The service is billed as a monthly or yearly subscription. Current prices and plan contents are shown on the pricing page before you order. Prices include VAT where charged. Subscriptions renew automatically at the end of each billing period until cancelled. We will announce price changes at least 30 days in advance; they take effect at your next renewal.
5. Free trial
- Every subscription starts with a 7-day free trial that includes 20 exercise generations.
- Each user may use the trial only once.
- You may end the trial early at any time; in that case the subscription is charged immediately, the 20-generation trial limit no longer applies and your plan is unlocked in full.
- If you do not cancel before the trial ends, it automatically converts into a paid subscription.
6. Payments
Payments are processed by Stripe. A valid payment method is required when starting the trial. If a payment cannot be collected, we may restrict or suspend access to paid features.
7. Cancellation and right of withdrawal
You can cancel your subscription at any time in the settings via the billing portal; you keep access until the end of the period already paid, which is not refunded pro rata unless the law provides otherwise.
As a consumer you have a statutory right to withdraw from the contract within 14 days of concluding it, without giving a reason. By starting to use the service within that period you expressly consent to its immediate performance and acknowledge that you lose the right of withdrawal to the extent the service has already been performed. To exercise withdrawal, write to info@numibo.com.
8. Account deletion
You can delete your account at any time in the settings. Deletion immediately cancels any active subscription and the account can no longer be used to sign in. Data we must retain for invoicing and tax purposes is kept in line with our privacy policy.
9. Acceptable use
You may print and use the generated worksheets for personal, family or teaching purposes. It is not permitted to resell or mass-redistribute content without our consent, to share one account between multiple households or organisations, or to abuse, automate access to, reverse-engineer or disrupt the service.
10. Intellectual property
The Numibo name, website, application and exercise-generation engine are the provider's intellectual property. Worksheets you generate may be freely used within the scope of section 9; this does not transfer any rights in the service itself.
11. Liability
We provide the service with due care but do not guarantee uninterrupted availability. Exercise content is educational in nature. Our liability is limited to the extent permitted by applicable law; this limitation does not apply to damage caused intentionally or by gross negligence and does not affect mandatory consumer rights.
12. Changes to these terms
We may amend these terms; we will notify you of material changes by email or in the application at least 30 days before they take effect. Continued use of the service after changes take effect constitutes acceptance.
13. Governing law and disputes
These terms are governed by the law of the Republic of Slovenia. Disputes are subject to the competent court in Ljubljana, except where consumer law provides otherwise. The EU online dispute resolution platform is available at ec.europa.eu/consumers/odr.
