Terms of Service

Last updated:

These Terms of Service (“Terms”) are an agreement between you and MTNT Solutions FZE (“we”, “us”) about the MathMe application (“the App”) on iOS, Android and the web, and the website math-me.com. See also our Privacy Policy and the Children and Teens page.

By using the App you agree to these Terms. If you do not agree, please do not use the App.

1. Acceptance of Terms and Who Can Use MathMe

By creating an account or using MathMe on any platform, you accept these Terms and acknowledge our Privacy Policy. When you first open the App and when you sign in, we ask you to confirm the following:

  • You are at least 13 years old — or older, if the law of your country sets a higher age for using online services or giving consent to data processing (the “age of digital consent”).
  • If you are under 18, a parent or legal guardian has reviewed these Terms and the Privacy Policy, agrees to them and gives you permission to use MathMe. A parent or guardian who gives that permission accepts these Terms for themselves and for you, and is responsible for your use of the App — including any purchase made through the store account you use.

We rely on your confirmation. We do not verify anyone’s age, and we do not check who a parent or guardian is. MathMe is not for children under 13: if we learn that an account belongs to a child under 13, we close the account and delete its data (see section 4).

You may not accept these Terms for anyone other than yourself or, as a parent or guardian, your child.

2. The Service

MathMe is an app for training mental arithmetic, for everyone aged 13 and older. It offers:

  • 6 game modes:
    • Practice — pick the operations (+ − × ÷) and the difficulty: Easy, Medium, Hard, Expert, or Random. No pressure.
    • Swipe — a timer on every question, a swipe to get the next one.
    • Arcade — 3 lives, a combo multiplier for consecutive correct answers, and difficulty that rises every 5 correct answers.
    • Survival — your health bar keeps draining; 5 types of power-ups help you last longer.
    • Time Attack — score as much as you can before the clock runs out. Fast answers multiply your points.
    • Duel (real-time multiplayer) — create a room and send the code to a friend, join a room by code, or let the app find an opponent. 10 rounds, one winner.
  • a mental math course
  • difficulty matched to your skill level
  • daily tasks, achievements and coins
  • progress statistics and leaderboards
  • sync between iOS, Android and the web with an account
  • 8 languages: English, Russian, German, French, Spanish, Italian, Portuguese, Turkish

3. Requirements

  • iOS — iOS 15.0 or later, from the Apple App Store
  • Android — Android 7.0 (API level 24) or later, from Google Play
  • Web — a current browser, at app.math-me.com

Duels, leaderboards, sync and the purchase of MathMe Pro need an internet connection; Practice and Swipe also work offline. Features may differ slightly between platforms; for example, MathMe Pro cannot be bought on the web.

4. Your Account

  • Age. You must be at least 13 (or the age of digital consent in your country, if higher) to use the App and to create an account. If you are under 18, you need the permission of a parent or guardian as described in section 1. We rely on the confirmation you give at sign-in and do not verify it. If we learn that an account belongs to a child under 13, we close it and delete its data; a parent or guardian can ask for this at mathme@mtnt-solutions.com.
  • Sign-in. Practice and Swipe can be used as a guest. The course, Arcade, Survival, Time Attack, duels and leaderboards need a free account, created by signing in with Google or Apple. We never see your Google or Apple password.
  • One account per person. Keep access to your Google or Apple account secure; you are responsible for what happens in the App under your account. Tell us at mathme@mtnt-solutions.com if you think someone else is using it.
  • Deletion. You can delete your account at any time: Profile → Settings → Delete Account, or by writing to mathme@mtnt-solutions.com from the email address of the account. It is deleted permanently 30 days after the request; signing in within those 30 days cancels the deletion. Deleting the account does not cancel a subscription — cancel it in the store (see section 8).

5. Licence

We grant you a personal, non-exclusive, non-transferable, revocable licence to use the App on devices you own or control, for your own non-commercial use, in line with these Terms and the rules of the store you got the App from. You may not:

  • copy, modify, sell, rent or distribute the App or its content;
  • decompile, reverse engineer or try to extract the source code, except where the law allows it;
  • remove copyright or other notices;
  • use the App for commercial purposes without our written permission.

6. Acceptable Use

When you use the App, you agree:

  • not to cheat — no bots, scripts, automation, modified clients or exploitation of bugs to gain coins, points, rankings or rewards;
  • to play duels fairly and respect your opponents — no deliberately abandoned or manipulated matches;
  • to choose a nickname and avatar that are not offensive, hateful, sexual, misleading or someone else’s name or trademark;
  • not to try to access other accounts, our servers or data you are not allowed to see, and not to disrupt the App;
  • to use the App only for lawful purposes.

If you break these rules we may reset affected points, coins or rankings, change your nickname or avatar, or suspend or close your account (see section 12).

Reporting a player. The only things other players can see about you are your nickname, avatar and scores — on leaderboards and in a duel. If a nickname or avatar breaks these rules, write to mathme@mtnt-solutions.com with the nickname and where you saw it; we review every report and act within a reasonable time.

7. Content and Intellectual Property

The App and everything in it — the course, lessons, problems and tasks, texts, design, graphics, software and trademarks — belong to MTNT Solutions FZE or its licensors and are protected by intellectual property laws. These Terms do not give you any rights to them except the licence in section 5.

Your nickname and avatar choice are your content. You give us a worldwide, non-exclusive, royalty-free licence to store them and show them to other players — on leaderboards and to your duel opponents — for as long as your account exists.

8. MathMe Pro Subscription

MathMe is free to use. All game modes are available at no cost; the free version shows ads.

MathMe Pro is an optional auto-renewing subscription. It unlocks the full mental math course (39 topics in 7 chapters), removes ads, gives unlimited hints and 2× coins. Three plans are offered: weekly, monthly and yearly; each renews for the same period. The price of each plan in your currency is shown in the App Store or Google Play before you confirm the purchase and may differ by region.

Free trial. New subscribers get a 7-day free trial. Whether you are eligible is decided by the store: as a rule, once per Apple ID or Google account. Unless you cancel at least 24 hours before the trial ends, the subscription starts and your store account is charged for the first period. Any unused portion of a free trial is forfeited when you purchase a subscription.

Renewal. Payment is charged to your App Store or Google Play account when you confirm the purchase (or when the trial ends). The subscription renews automatically at the end of each period unless it is cancelled at least 24 hours before the period ends; your account is charged for the renewal within 24 hours before the end of the current period. If the price changes, the store informs you in advance and, where its rules or the law require it, asks for your agreement.

Managing and cancelling. You can manage or cancel the subscription at any time in the store’s subscription settings (iOS: Settings → Apple ID → Subscriptions; Android: Google Play → Payments & subscriptions → Subscriptions). Cancelling stops future renewals; Pro stays active until the end of the current period. Deleting the App or your account does not cancel the subscription.

Refunds. Purchases are made with Apple or Google, and refunds follow their policies: request them from Apple at reportaproblem.apple.com or from Google Play. We do not refund the current period ourselves. This does not affect any right to a refund or withdrawal that the law of your country gives you.

Purchases by users under 18. A purchase made through a store account counts as made with the permission of the account holder and of the parent or guardian who allowed the use of MathMe (section 1). Parents can require approval for purchases with the store’s family tools — Ask to Buy on Apple devices, purchase approval in Google Family Link.

When a subscription ends. When a subscription ends, the course returns to its free starter topics, ads return, and hints return to the free allowance. Coins, progress and statistics are kept.

Restoring. Pro is linked to your store account and your MathMe account; sign in with the same account and use “Restore purchases” to unlock Pro on another device.

9. Coins

Coins are a virtual in-app currency. You earn them by playing, completing daily tasks and achievements and, in the free version, by watching optional rewarded ads; MathMe Pro doubles what you earn. You spend them on in-app items such as hints and items in the shop.

  • Coins have no monetary value and are not money or property; they cannot be cashed out, exchanged for money, goods or real-world prizes, transferred to another account, exchanged for anything outside the App or refunded.
  • They are a limited licence to use in-app items. We may change how coins are earned and what they buy, and we may reset coins obtained through cheating, bugs or other breaches of these Terms.
  • Coins are deleted with your account.

10. Promo Codes and Promotions

Promo codes. Promo codes issued by MathMe grant MathMe Pro for the period stated with the code and do not renew. A code can be redeemed once, may have an expiry date, has no cash value and may not be sold or traded. When the period ends, Pro ends as described in section 8, unless you have a paid subscription.

Promotions. Invitations (a friend who joins with your invite gets a coin bonus), events and other promotions follow the rules shown with them in the App. Rewards are always in-app items or coins — never money or real-world prizes. We may end or change a promotion; rewards already credited stay. Rewards obtained by abusing a promotion, for example with fake accounts, may be removed.

11. Availability and Changes

We keep improving MathMe, so features, modes and content may change, and we may discontinue a feature or the App. We do not promise that the App will always be available or free of errors; maintenance, outages of stores or providers and similar events may interrupt it. If we discontinue MathMe Pro or the App while you have an active subscription, you can ask the store for a refund under its policy.

Changes to these Terms. We may change these Terms when the App, the law or our business changes. For a change that affects your rights or obligations, we will tell you at least 30 days before it takes effect — in the App or on this website — and explain the reason. If you do not agree with a change, stop using the App before the change takes effect and, if you have a subscription, cancel it in the store; you can also delete your account. Changes that only correct errors, clarify wording or are required by law may take effect sooner. The date of the current version is shown at the top of this page; earlier versions are available on request.

12. Termination

You may stop using the App at any time and delete your account in the App. We may suspend or close your account, or reset coins, points or rankings, if you seriously or repeatedly break these Terms, if the law requires it, or to protect other players or the App. Where reasonable, we will tell you why and give you a chance to respond. If we close your account for a breach, a subscription is not refunded by us; refunds remain subject to the store’s policy and to your statutory rights. Sections 7, 9, 13, 14 and 15 survive termination.

13. Disclaimers and Limitation of Liability

We provide the App with reasonable care and skill, but “as is” and “as available”: to the extent the law allows, we give no guarantee that it will work without interruption or errors, or that it will lead to particular learning results.

To the extent the law allows, MTNT Solutions FZE is not liable for indirect or consequential loss, loss of data, profits or goodwill, and our total liability for all claims relating to the App is limited to the greater of (a) the amount you paid for MathMe Pro in the 12 months before the claim arose and (b) the price of a yearly MathMe Pro subscription in the App Store or Google Play of the country of your store account at the time the claim arose.

Consumers. Nothing in these Terms limits or excludes liability for death or personal injury caused by negligence, for fraud, for intentional or grossly negligent conduct, or any other liability that cannot be limited or excluded by law. If you are a consumer, you keep all rights that mandatory consumer-protection law of your country gives you — for example, in the EU and the UK, the statutory rights for digital content that does not conform to the contract — and these Terms do not affect them.

14. Governing Law and Disputes

These Terms are governed by the laws of the United Arab Emirates (UAE). Please contact us first at mathme@mtnt-solutions.com — most problems can be solved that way. Disputes that cannot be settled by negotiation go to the courts of Sharjah, UAE.

Nothing in this section deprives you of the protection of mandatory consumer-protection law of the country where you live, or of the right to bring proceedings there. If you live in the EU, you can also use the dispute resolution bodies available in your country.

15. Severability

If any provision of these Terms is held invalid or unenforceable, it is limited to the minimum extent necessary and the remaining provisions stay in full force and effect.

16. Assignment

You may not transfer your rights or obligations under these Terms. We may transfer these Terms to a successor of the App, for example in a merger or sale; your rights under these Terms are not reduced by such a transfer.

17. Force Majeure

We are not responsible for a delay or failure to provide the App caused by events beyond our reasonable control, such as outages of app stores, hosting or network providers, natural disasters or acts of government.

18. Entire Agreement, App Stores and Export Rules

These Terms and the Privacy Policy are the entire agreement between you and MTNT Solutions FZE about the App. Purchases are also subject to the terms of the App Store or Google Play. Apple and Google are not parties to these Terms and are not responsible for the App or its support.

Apple App Store. If you got the App from the App Store, the following also applies. These Terms are between you and MTNT Solutions FZE only, not Apple; Apple’s Licensed Application End User License Agreement applies in addition, and if it conflicts with these Terms in respect of a purchase made through the App Store, it prevails. We, not Apple, are responsible for the App, its content, maintenance and support; Apple has no obligation to provide any support for it. If the App does not conform to an applicable warranty, you may tell Apple and Apple will refund the purchase price of the App (if any); to the extent the law allows, Apple has no other warranty obligation. We, not Apple, are responsible for addressing any claim by you or a third party relating to the App — including product-liability claims, claims that the App does not comply with a legal or regulatory requirement, and consumer-protection claims — and for the investigation, defence and settlement of any claim that the App infringes a third party’s intellectual property. The licence in section 5 covers use on Apple devices you own or control, as allowed by the App Store usage rules, including through Family Sharing. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

Export rules and sanctions. You may not use the App where its use is prohibited by law, and you confirm that you are not located in a country subject to a government embargo that prohibits the use of the App and that you are not on any government list of prohibited or restricted parties. You will comply with any third-party terms that apply to your use of the App, such as your mobile carrier’s terms.

19. Intellectual-Property Complaints

If you believe that something in the App or on this website infringes your intellectual property rights, write to mathme@mtnt-solutions.com with a description of the work, where it appears and your contact details.

20. Accessibility

We work towards WCAG 2.2 AA in the App and on this website and fix barriers we find; an independent accessibility audit has not yet been carried out. Report barriers to mathme@mtnt-solutions.com.

21. Language

These Terms are drafted in English. In case of translation, the English version takes precedence, unless the law of your country requires otherwise.
