Terms of service

1. Provider and scope

NitroStudy is provided and sold by Kemax12 (vof), Falckstraat 21, 2515 KM The Hague, Netherlands, Chamber of Commerce 93024290, VAT NL866251777B01. Contact info@nitrostudy.com or our contact form. These terms govern personal use of the website and app. Mandatory consumer rights remain unaffected.

2. The service and AI

Your own study material can become a learning path, explanations, quizzes, flashcards, summaries, podcasts and video lessons. The tutor, generated text and voices use AI. AI can make mistakes: check important information against your material or with a teacher. Mastery is practice feedback, not an official grade. NitroStudy replaces neither a teacher, qualification or examination nor professional advice. No particular grade or study result is guaranteed.

3. Age and account

The app is intended for ages 12 and over. Provide accurate details and use your own account. We keep the age group 12–15, 16–17 or 18+, not the exact age entered. Under 16, learning remains blocked until a parent or guardian with parental responsibility actively consents. Silence or merely opening an email is not consent. We confirm access to the email address and request a guardian declaration; reasonable additional checks may be requested when there is doubt. This is not independent identity verification.

A subscription for a minor is purchased by an authorised parent or guardian. The buyer confirms adulthood or that authority. Data-processing consent and authority to buy are separate matters.

From age 18 you independently manage your account and may purchase a plan. Parent oversight is voluntary and can be stopped through the privacy action. Ages 16–17 do not require under-16 consent for ordinary learning, but a paid plan is arranged by an authorised guardian. Existing parent-paid billing and payment data are not automatically transferred to the learner. Legacy 16+ accounts first confirm a more specific age group, as a self-declaration rather than independent age verification. A recorded minor group cannot be self-upgraded to 18+; contact us about a birthday or correction.

4. Plans and prices

The free version has usage limits. Every paid offer shows the total price including applicable VAT, period, functions and limits before payment. Kemax12 supplies and sells the service; Stripe processes payments and billing management. Using Link as a payment method alone does not make Link the seller. A paid contract is concluded at final payment confirmation; an app continue button or a request to a parent does not buy a plan.

A monthly plan renews monthly until cancelled. A new yearly plan provides one year of access and then stops; no further year starts without a new choice. You may cancel in advance and keep access until the agreed end. For any older automatically extended agreement, cancellation after the first fixed term is subject to no more than one month's notice, with unused advance payment returned; a shorter agreed notice is honoured. Cancel online in Settings → Subscription or via info@nitrostudy.com. Price changes do not affect an already paid period and are notified before renewal so you can cancel first.

Changes show the new price, start date and any adjustment before confirmation. The purchase confirmation provides the agreed details and retainable copies of these terms and withdrawal information.

5. Cooling-off period and immediate start

A paid subscription has a statutory 14-day cooling-off period after the contract is concluded, without needing a reason. Immediate access does not automatically remove it. If you expressly request immediate start before purchase and receive prior information about proportionate payment, timely withdrawal only incurs the elapsed service portion of the agreed period. Without the required request or information we do not charge it. We use the actual paid period and only round the final amount. For €50 over 30 days withdrawn after one day, the charge is €1.67 and the refund €48.33. We deduct no administration or Stripe transaction fees.

Use the online withdrawal function, info@nitrostudy.com or the model form. The function is also available from Settings → Subscription. You receive a dated acknowledgement and reference. We handle termination and any refund due within 14 days of withdrawal through the original payment method, unless you expressly choose a cost-free alternative. Ordinary cancellation, withdrawal and remedies for a faulty service are distinct rights.

6. Parents, oversight and payments

A learner may share a single-use code valid for 24 hours. Once redeemed, the link lasts 365 days. A parent controls the ordinary unlink action; the learner can separately stop oversight through the privacy function. Statutory privacy rights remain. Parents see limited study times, days, level and streaks, not material, answers or conversations.

A study link does not automatically grant access to payment data. The recorded buyer may explicitly authorise another actively linked parent to manage the subscription and associated billing data. Only the buyer grants or revokes that authority. Revocation blocks new management sessions; do not share an already opened Stripe link. Authority for older plans without a recorded buyer is checked first. Accounts under 18 do not receive a purchase-request prompt; a parent may arrange a plan from their own linked parent account. Where available, a request to a parent is optional; opening its email buys nothing.

7. Material and sharing

You retain rights to your own material and grant a non-exclusive licence to store and technically process it, including through our service providers, only as needed to deliver your requested learning functions. This is neither a sale of your content nor permission to train models on it. Public sharing requires a separate action by you. Do not upload unlawful material or other people's private data or violate others' rights. Private study does not automatically permit public sharing; summaries may also be protected. Share only material you have sufficient rights to share.

Community sharing and links publish a snapshot of summaries, not original files. Titles and summaries can reveal information; imported copies may remain after sharing is stopped. Report illegal content with its location and reason through the course report action or info@nitrostudy.com. We acknowledge, examine and respond, and provide reasons where required. Challenge a decision through the same contact, also our contact point for authorities in Dutch and English.

8. Safe and fair use

No fraud, exam cheating, harassment, discrimination, threats, privacy abuse, account misuse or bypassing security. Follow school rules. We may restrict content or access for violations, explaining why unless law or safety prevents this, with appropriate opportunities to remedy or challenge a decision.

A complaint, negative review, lawful withdrawal, privacy request or disputed payment is not by itself misuse. We assess the facts and choose a proportionate restriction. For a correctable breach we normally give an explanation and opportunity to remedy it. Serious fraud, unlawful content or an urgent security risk may require immediate action. We explain the reason, scope and duration where possible, and you may challenge our decision via info@nitrostudy.com. Access to applicable privacy rights and payment remedies remains. We do not charge an automatic penalty or retain all unused payments merely because access is restricted; any amount legally due depends on the actual circumstances.

9. Quality and changes

The service must meet reasonable expectations. We provide necessary security updates and seek a free remedy for defects. Statutory rights to correction, price reduction or termination remain. For a materially detrimental paid-plan change, we notify you in advance and provide legally required cost-free termination and unused advance-payment refunds. AI warnings do not exclude statutory responsibility.

10. Protecting the service and responsibility

NitroStudy software, design, name and original content remain owned by Kemax12 or the relevant rights holder. Your plan provides a personal, non-transferable right to use the service during the agreement. Automated bulk extraction, reselling access, account sharing and bypassing usage limits require prior written permission. Mandatory statutory exceptions remain unaffected.

You are responsible for content you knowingly upload or publish and for keeping login credentials private. Report suspected misuse promptly. We assess the facts; we do not automatically make you responsible for every error, unauthorised payment or loss. AI output may be non-unique or lack copyright protection. We do not transfer rights we do not hold.

We work to provide reliable access but cannot promise uninterrupted availability or error-free AI. Necessary maintenance, security action and supplier outages can temporarily limit functions. We reduce disruption and give notice of material disruption where possible. Statutory remedies for failure to supply or defects remain, including where a supplier we engage is involved.

Liability follows statutory rules on attribution, causation and contributory fault. Reasonably avoidable loss should be mitigated where possible. We do not exclude liability for intent, deliberate recklessness or any liability that cannot legally be excluded. Dutch governing law does not remove mandatory protection in your country of habitual residence.

11. Ending use, data and complaints

Delete an account in Settings → Security. Access, correction and applicable export rights remain available even without a download button in the viewer. Use the privacy functions or info@nitrostudy.com for other requests. If we stop the service, we give prior notice and handle unused advance payments appropriately. Complaints receive a response within 14 days. Dutch law applies without removing mandatory consumer protection or your competent local court. Terms changes are normally notified at least 30 days ahead; detrimental changes allow cost-free termination before taking effect.

Plus, Ultra and Ultimate distribute the allowance for new AI tasks across daily 24-hour periods. Their internal AI cost budgets are at most €10, €12 and €25 respectively per monthly subscription period, with a daily ceiling equal to the monthly budget divided by 30. Unused daily allowance does not accumulate. Text and personal podcast audio share the budget. Costs are conservatively reserved in advance; uncertain or failed provider attempts may consume allowance. Saved lessons remain accessible. Annual subscriptions have separate monthly budgets.

NitroStudy is under development. We continuously improve the app. Some features may contain errors, be temporarily restricted or not yet work fully as expected. We inform you before purchase about material limitations and do not describe planned features as already available. This development status does not limit your statutory rights, including withdrawal rights and remedies for failure to supply or lack of conformity. It does not generally exclude our statutory obligations.
