Materact is an educational technology platform that transforms the way mathematics is taught by offering each student the personalised experience of a private tutor powered by artificial intelligence (AI). Our mission is to revolutionise mathematics education and support the academic success of millions of students through a personalised, accessible, and effective learning experience. Materact integrates an interactive digital whiteboard that recognises handwriting and understands mathematical language, alongside a system for automatic step-by-step corrections, real-time doubt resolution, and tailored recommendations. Offered on a per-user subscription basis, it aligns with university entrance exam curricula, providing a unique solution for mathematics education.
This document together with the documents mentioned herein establishes the terms and conditions (the "Terms and Conditions") by which "we", Naiguru, S.L., will provide the student (“Student” or “you”), with the e-learning services of the Materact platform (the "Platform").
Our Privacy Policy explains how we collect and use your or the Student’s parent/guardian’s information, to provide the Services described below.
We are responsible for the content shared on the Platform. Below are our contact details:
We are the sole owner of the Platform, and we grant you a license to use the Platform (the "License"). The License is granted on a non-exclusive and non-transferable basis, for the territory where you are based and for the entire duration of the Subscription.
We provide the following e-learning services and features in the Platform:
Together, the "Services".
We undertake to provide the Services with appropriate professionalism, confidentiality and good faith; and complying with the Terms and Conditions and with all obligations, requirements and deadlines specified therein. We will perform all activities necessary for the provision of the Services at our sole risk and responsibility and will be responsible for the performance of the Services in accordance with the Terms and Conditions. We will inform you as soon as possible of any circumstances that may affect the Services and/or impact their availability or delivery.
The Services available through the Platform provide results powered by artificial intelligence systems (the "Results"). These Results are based on [neuroscience principles and teaching theory] to deliver personalised educational content and on your in-put (e.g., images, text queries, requests, etc.) (“Prompts”).
AI is a new technology that is still improving in accuracy. As such, the accuracy of any content, including Results, cannot be guaranteed and we make no guarantees that they will be safe, secure or error-free, or will function without disruptions, delays or imperfections. The Results should be treated as learning aids rather than definitive answers. You or your parents/guardians are responsible for verifying and validating the Results before making any decisions based on them. To the extent permitted by law, we are not responsible for your use of the Results, or for any consequences that may result, from any decisions you make or actions taken from the Results.
Our AI feature may use or be used in connection with content, services, features and integrations (including AI tools) provided by third parties ("Third-party Materials and AI"). We are not the provider of these Third-party Materials and AI and are not responsible for your use of Third-party Materials and AI; you use these at your own risk.
We want Students to use the Platform to enhance their educational skills, by accessing to the Services and sharing information with us. But not at the expense of the safety and well-being of others or the Platform. Therefore, you agree not to engage in the conduct described below (or to facilitate or support as parent/guardian in doing so):
We can remove, block or restrict content that is in breach of these provisions. We can also suspend or disable your account for conduct that violates these provisions.
We need certain permissions from you or your parent/guardian to provide and improve our Services. Some content that you share or upload (such as photos of your homework, feedback or Prompts) may be protected by intellectual property laws. You retain ownership of the content that you create and share on the Platform. However, to provide our Services, we need you or your parent/guardian to give us some legal permissions to use this content. This is solely for the purposes of providing and improving our Platform and Services. Specifically, when you share, submit or upload content that is covered by intellectual property rights on or in connection with our Platform, you or your parent/guardian grant us a non-exclusive, transferable, sub-licensable, royalty-free and worldwide licence to host, use, distribute, modify, run, copy, publicly perform or display, translate and create derivative works of your or the Student’s content. This means, for example, that if you share a photo on the Platform, you give us permission to share it with others such as service providers that support the Platform. This licence will end when your content is deleted from our systems.
To ensure optimal performance of the Platform, it is recommended that Students use tablets with resolutions between 1024x768 and 1366x1024. We cannot guarantee optimal performance outside of these recommendations. You will need to make sure that your devices are free of viruses and are in good condition. We strive to ensure accessibility to the Platform, but we do not guarantee the absence of interruptions or errors. We will not be liable for damage caused by telecommunications failures. We do not control the absence of viruses and are not responsible for any damage caused by them.
Students are required to enter their name, email address, create a password, verify their email, and confirm their age to register on the Platform. If the Student is at least 18 years old, they can complete the registration themselves; otherwise, their parents or guardians must finish the process on their behalf.
Before granting you access to the Platform, the Students (over 18 years old) or the Students’ (under 18 years old) parent/guardian must indicate the exam plans wished to contract and are shown the relevant plan information and rates of the selected plans (the "Subscription").
The Students or their parents/guardians can select more than one exam plan. Each exam plan relates to a specific qualification (e.g. IGCSE, A Level) and is available across different awarding bodies (e.g. Edexcel, AQA, OCR, WJEC) and gives the Student access to all the Platform Services.
Once the account creation process has been formalised, the Student will be able to access the Platform.
We offer a 7-day free trial. When you create an account, you (or your parent/guardian) will be asked to provide payment details. You will not be charged during the trial period. At the end of the 7-day trial, the Subscription fee will be charged automatically unless the Subscription is cancelled before the trial ends.
The Platform will operate on a monthly or annually subscription basis per Student (“Subscription Period”), with block pricing options, with costs varying depending on the selected plans. All prices shown during the purchase process are accurate but are subject to change. The latest Platform Service plans and the terms and rates applicable to them, are available at www.materact.com. The Subscription shall automatically renew at the end of Subscription Period month/year unless cancelled.
When you or the Student’s parent/guardian make a payment or store a payment instrument through the Platform, you agree to be bound by these Terms and Condition and to provide a valid payment instrument. For clarity, a payment instrument includes a credit card, debit card, and other payment methods that enable electronic funds transfers. When you use a payment instrument, you or the Student’s parent/guardian confirm that you or the Student’s parent/guardian are permitted to use that payment instrument or have permitted a Student to use the payment instrument. You or the Student’s parent/guardian agree to keep your stored payment instruments up to date.
When you or the Student’s parent/guardian initiate a transaction, you or the Student’s parent/guardian authorise us (and our designated payment processor) to charge up to the full amount to your payment instrument. Where necessary to process your transactions with third-party providers, you or the Student’s parent/guardian permit us to share your payment instrument details and other information necessary to process your payment, with the provider and their payment processors.
Pay attention to the details of the transaction, because your total price may include taxes, or fees, all of which you or the Student’s parent/guardian are responsible for paying. You or Student’s parent/guardian are responsible for providing us with true and accurate information. Ensure sufficient funds are available for each payment; failure to do so may result in suspension of access and your or the Student’s parent/guardian card issuer or bank may charge you a fee, and you or the Student’s parent/guardian alone are responsible for that fee.
You or the Student’s parent/guardian will be billed at the beginning of each Subscription period. We will continue to bill your or the Student’s parent/guardian payment credential each Subscription period until you or the Student’s parent/guardian have cancelled. To avoid any charges, you or the Student’s parent/guardian must cancel before the end of the Subscription Period.
When you or the Student’s parent/guardian purchase a Subscription, you or the Student’s parent/guardian will initially be charged at the rate applicable at the time of your agreement to subscribe. If the price of the Subscription increases later, we will notify you. The increase will apply to the next payment due from you after the notice, provided that you have been given prior notice as required by law, and in no case less than 10 days prior notice before the change is made. If you are given less than the applicable notice period, the price increase will not apply until the payment after the next payment due. If you do not wish to pay the increased price for the Subscription, you or the Student’s parent/guardian may cancel the Subscription in the manner described in the below “Cancellation and Termination” section.
You may be subject to additional third-party terms and conditions, which are hereby incorporated by reference. Such terms may include terms from the Apple App Store, Google Play Store, or Microsoft Store (including any applicable regional or country-specific terms) for purchases made through their services. You are solely responsible for compliance with such third-party terms.
You or the Student’s parent/guardian can cancel the Subscription at any time. Cancellation of the Subscription will imply the automatic closure of the Platform and the interruption of the Services. To avoid any charges, you or the Student’s parent/guardian must cancel before the end of each Subscription Period. Refunds are not available for Subscription purchases unless you or the Student’s parent/guardian request cancellation: (i) within 14 days of your first Subscription payment date; or (ii) when the price of your next Subscription increases, within 14 days of your renewal Subscription payment date.
The Subscription may be cancelled from the Student’s account in the Platform by accessing “My Profile” (side menu) and selecting “Manage Subscription” > “Cancel Subscription”. A parent/guardian may cancel on the Student’s behalf by accessing the Student’s account and following the same steps. Alternatively, the account may be closed via “My Profile” > “Manage Account” > “Delete Account”, which will terminate access to the Platform (and any active Subscription).
We reserve the right to suspend your access to our Platform or terminate your Subscription, without notice or refund, if we have reasonable grounds to believe that:
In general, we will notify you in advance and provide you with an opportunity to remedy the relevant breach or breaches. However, advanced notification and/or opportunity to remedy will not be provided if the seriousness of the breach requires immediate termination of your access to the Platform. We may also terminate our relationship by cancelling the Subscription. The following provisions of these Terms and Conditions shall survive termination (this means that these terms remain legally enforceable): 2.6, 2.9, 2.11-2.17.
We will exercise professional diligence in providing our Services to you and in keeping a safe, secure and error-free environment. Provided that we have acted with professional diligence, we do not accept responsibility for losses not caused by our breach of these Terms and Conditions or otherwise by our acts; losses that are not reasonably foreseeable by you or the Student’s parent/guardian and us at the time of entering into these Terms and Conditions; and events beyond our reasonable control. Our maximum liability to you under these Terms and Conditions in respect of any Subscription will be limited to the minimum of (i) EUR 150 or (ii) the Subscription fees paid by you in the 12 months before the event giving rise to the claim.
Total or partial reproduction of the Platform and/or the Services, including of all its content, both registered and unregistered, is prohibited. We are the exclusive owners of the Platform. You may not modify, translate, create derivative works of, decompile or reverse-engineer our Platform or their components, or otherwise attempt to extract source code from us. We reserve all rights not expressly granted to you or the Student’s parent/guardian.
We will comply with the applicable personal data protection regulations when processing your personal data within the framework of the provision of the Services, as detailed under our Privacy Policy.
If any portion of these Terms and Conditions is found to be unenforceable, the unenforceable portion will be deemed amended to the minimum extent necessary to make it enforceable and if it can't be made enforceable, then it will be severed and the remaining portion will remain in full force and effect. If we fail to enforce any of these Terms and Conditions, it will not be considered a waiver. Any amendment to or waiver of these Terms and Conditions must be made in writing and signed by us.
We may engage third parties to provide Services as needed. If subcontracting occurs, we remain responsible for the actions of those companies and their personnel.
The Terms and Conditions contain the entirety of what has been agreed between you and us on the subject matter of this Agreement. Each of the documents referred to in the Terms and Conditions, as well as any future updates or additions that may be agreed, shall form an integral part of the Terms and Conditions. Any modifications or additions made will not be retroactive and we will notify you. You can see the last modification at the bottom of these Terms and Conditions. If you do not agree with the modifications made, you must not use or authorise the use of the Platform.
If a claim or dispute arises out of or relates to your use of the Platform as a consumer, both you (or the Student’s parent/guardian in your behalf) and us agree that you may resolve your individual claim or dispute against us, and we may resolve our claim or dispute against you, in any competent court in the country of your main residence that has jurisdiction over your claim or dispute, and the laws of that country will apply without regard to conflict of law provisions.
If a claim or dispute arises between us that relates to use of the Platform in any other capacity, including, but not limited to, access or use of the Platform for a business or commercial purpose, or that an entity brings on your behalf, you agree that any such claim or dispute must be resolved in a competent court in Spain and Spanish law will apply to such claim or dispute without regard to conflict of law provisions.
