Terms of Use

Last updated: September 7, 2026

These Terms of Use are a binding agreement between you and Moozgy, governing your use of the Moozgy website (moozgy.com) and the Moozgy iOS app, including any subscription, gift, or pre-launch purchase. In this document, "Moozgy," "we," "us," and "our" refer to the individual founder who owns and operates the Moozgy project as a sole proprietor, currently based in Italy (contact details in Section 21 below). "You" means the person using the website or the app. Operation of Moozgy and these Terms may be assigned to a company formed for the Moozgy business in the future (see Section 20).

By using the website, creating a Moozgy account, using the app, or completing a purchase, you accept these Terms. If you do not agree — including the arbitration agreement and class action waiver in Section 18 — do not use the website or the app. See also the Privacy Policy, which describes how we handle your data.

1. Agreement; eligibility

You must be at least 13 to use the website or create a Moozgy account, and at least 18 (or the age of majority in your place of residence) to make a purchase — including a subscription, gift, or the website's Founder plan. This 13+ minimum is Moozgy's own requirement and applies regardless of the age rating shown for the app in your country's App Store. If a parent or guardian believes a child under 13 has created an account, contact us (Section 21) and we will delete it.

2. The Moozgy service

Moozgy is a mental-fitness product for capable adults — a feed of hard STEM problems (undergrad through research level) with an adaptive difficulty engine, an AI-assisted "Explain Anything" feature, and an AI coach, delivered through the website (pre-launch) and the Moozgy iOS app. Moozgy is a game and learning tool, not a medical or clinical product — see Section 8.

Website purchases

3. The pre-launch offer

Moozgy is an app in development, currently expected to launch soon (iOS first). This site offers two pre-launch options:

• Free spot — submit your email and, if you are among the first 500 free sign-ups, you will receive 2 months of the app's paid ("Full Brain") features at no charge, starting when the app launches and your account is created. After the 500 free spots are taken, free sign-ups join a launch waitlist with no promotional entitlement.
• Founder plan — a one-time purchase of US $19.99 that entitles you to 6 months of the app's Full Brain features at no charge from launch, plus any additional Founder-designated perks we announce. Founder availability is not capped.

One pre-launch benefit per person/email. A free sign-up may upgrade to Founder; the Founder benefit then replaces (does not stack with) the free benefit. The "spots claimed" counter reflects actual recorded sign-ups. We may modify, pause, or close either offer prospectively at any time; doing so will not reduce benefits already promised to recorded sign-ups.

4. Founder payments; refunds

Payment is processed by Stripe under its own terms. The price is stated in U.S. dollars and is exclusive of any taxes that apply in your jurisdiction, which will be shown at checkout where required. ALL FOUNDER PLAN PURCHASES ARE FINAL AND NON-REFUNDABLE, to the maximum extent permitted by applicable law, including without limitation in cases of change of mind, non-use of the benefits, or changes to the anticipated launch date — with one exception:

• Never-launch refund. If we permanently cancel the Moozgy app before making it generally available, we will announce the cancellation to the email address you provided, and you will be entitled, as your sole and exclusive remedy, to a refund of the amount you actually paid, upon request made within 90 days of that announcement, processed through the original payment method.

Nothing in this section limits any non-waivable rights you may have under the consumer-protection laws of your jurisdiction, including any non-waivable statutory withdrawal rights of EU consumers.

5. Gift purchases

A gift of Moozgy is a one-time, prepaid purchase (1/3/6/12 months of Full Brain, at the price shown at checkout) processed by Stripe, redeemable by the recipient in the app using the code generated at checkout. A gift is not a recurring subscription and does not auto-renew. Once a gift code has been generated, the purchase is final and non-refundable, except where required by applicable law or where the code was never delivered due to our error. An unredeemed gift code does not expire the underlying app functionality, but may be subject to a reasonable redemption window disclosed at checkout.

The Moozgy app

6. Moozgy Full Brain subscriptions (in-app)

Moozgy Full Brain unlocks the app's full feature set (including deeper AI coaching and Explain usage) through an auto-renewing subscription purchased via Apple's In-App Purchase (StoreKit), in the following standard plans (App Store Connect pricing and any regional/tax adjustments govern at time of purchase):

• Yearly — currently US $59.99/year, may include a free trial (e.g. 7 days) where offered at the point of purchase.
• Monthly — currently US $9.99/month, may include a free trial (e.g. 7 days) where offered at the point of purchase.
• Weekly — currently US $2.99/week, may include a short free trial (e.g. 3 days) where offered at the point of purchase.

From time to time we may also offer a discounted introductory monthly price to a specific user (for example, through the app's promotional wheel); any such offer is itself an auto-renewing monthly subscription at the discounted price shown at the time, governed by these same Terms.

Key subscription terms, as required by Apple:

• Payment. Payment is charged to your Apple ID account at confirmation of purchase.
• Free trial. Where a free trial is offered, any unused portion is forfeited when you purchase a subscription, where applicable. Full price is charged at the end of the trial period unless you cancel at least 24 hours before the trial ends.
• Auto-renewal. Subscriptions automatically renew for the same duration unless auto-renew is turned off at least 24 hours before the end of the current period. Your account will be charged for renewal within 24 hours prior to the end of the current period, at the then-current price for the plan you selected.
• Managing & cancelling. You can manage or cancel your subscription at any time in your Apple ID account settings (on iPhone: Settings → [your name] → Subscriptions), or from the Moozgy app (Settings → Moozgy Full Brain → Manage subscription), which opens the same Apple-managed screen. Cancelling stops future renewals; you keep Full Brain access through the end of the period you already paid for.
• Refunds. All subscription charges are billed and processed by Apple. Refund requests are handled by Apple under its own policies, not by us — see Apple's support page on requesting a refund. We do not have the ability to directly refund an App Store subscription charge.
• Price changes. If the price of a subscription changes, we will provide notice as required by Apple and applicable law before it applies to your next renewal; you may cancel before the change takes effect.
• Promo codes & gifts. Redeeming a promo code or a gift code extends your Full Brain access by the stated duration and does not, by itself, start or stop an auto-renewing subscription; if you hold both an active subscription and redeemed time, your Full Brain access reflects the combination and does not overlap or reduce either.

7. Apple licensed application terms

The Moozgy app is licensed, not sold, to you for use only on Apple-branded products that you own or control, as permitted by the Apple Media Services Terms and Conditions. Except for the subscription terms set out in Section 6 above (which supplement and take precedence for anything specific to Moozgy Full Brain), your use of the app is governed by Apple's Standard End User License Agreement (EULA), which is incorporated into these Terms by reference. Apple has no obligation to furnish maintenance or support for the app, and is not responsible for addressing any claims relating to the app or your possession/use of it, except as required by applicable law. Apple is a third-party beneficiary of these Terms as they relate to your license to use the app, and may enforce them against you.

8. Not medical, health, or professional advice

Moozgy offers puzzles, adaptive practice, and AI-assisted explanations for mental-fitness, entertainment, and general educational purposes only. Statements about attention, focus, "sharpness," or getting better at hard problems are descriptions of the product's intent, not scientific or medical claims. Moozgy is not a medical device; it does not diagnose, treat, cure, or prevent any disease or cognitive condition, and we make no representation that using it will improve your cognition, grades, memory, or any health outcome. Any "brain test" or placement score is a gameplay mechanic, not a diagnostic or clinical measurement. Consult a qualified professional for any health concern.

9. AI features

"Explain Anything" and the Coach use AI models (via our backend, as described in the Privacy Policy) to generate explanations and recommendations. AI-generated content may be incomplete, out of date, or occasionally incorrect, and is provided for educational purposes only — it is not professional, medical, financial, or legal advice, and you should independently verify anything important. Do not submit content through these features that you do not have the right to share.

10. Intellectual property

The website, the app, and everything in them — the Moozgy name and wordmark, text, design, illustrations, animations, puzzles, and code — are owned by Moozgy or its licensors and protected by intellectual-property laws. We grant you a limited, revocable, non-exclusive, non-transferable license to access and use the website and the app for personal, non-commercial purposes (and, for the app, subject to Section 7). You may share links to the site (including your referral link). You may not otherwise copy, scrape, frame, reverse-engineer, modify, or create derivative works from the website, the app, or its problem content without prior written permission.

11. Your content

Your content. Moozgy lets you create card sets, either by writing them yourself or by giving Coach source material to work from. You keep ownership of the material you provide and of the sets you create. You grant us only the limited permission we need to run the service for you: to process your source material to generate your cards, to store and display the sets you save to your own account, and — only for a set you choose to make public — to display that set and its cards to anyone who opens its link. We claim nothing beyond that, and we do not use your material to train AI models.

What you may upload. You must have the right to use and upload the material you provide. Do not upload material you do not have permission to use, other people's personal information, or health, biometric, or other sensitive personal data. Do not upload unlawful, abusive, or infringing material. We may decline to process, or remove, material that breaches this section.

AI-generated cards. Cards Coach generates from your material are provided for educational purposes and may be incomplete or occasionally incorrect, the same as any other AI-generated content in Moozgy.

12. Sets you publish

Sets you publish. Every set you create is private to your account unless you choose to make it public. Making a set public creates a link, and anyone who has that link can open the set and read every card in it, including people who do not use Moozgy. There is no password on it and no expectation of privacy in anything you publish this way.

Before you publish a set, make sure of two things. First, that you have the right to publish it — do not publish material copied from a textbook, a paper, a course, or anything else you did not write and are not licensed to share. Second, that it contains no personal information about anybody else — no names, contact details, or identifying details of real people, and no health or other sensitive information about them.

Published sets are covered by Section 15 the same as anything else you write on Moozgy: no obscene, hateful, sexually explicit, harassing, threatening, deceptive, or otherwise objectionable content, and nothing unlawful. We check sets when they are published and we act on reports, and we may remove a set from public view at any time, without notice, if it breaks these rules. If we do, the set stays in your account but cannot be made public again; write to hello@moozgy.com if you think we got it wrong.

You can make a set private again whenever you like, and its link stops working immediately. We cannot undo the sharing itself: anyone who already opened the set may have saved or copied what they read, and we have no way to reach those copies.

13. Copyright complaints

If you think something on Moozgy infringes your copyright. Moozgy lets people publish card sets they have made. If you believe a published set contains material that infringes a copyright you own or represent, tell us and we will act on it. Send your notice to the address at the end of this section, and include all of the following:

• your physical or electronic signature;
• identification of the work you say has been infringed, or a representative list if there are several;
• identification of the material you say is infringing, with enough detail for us to find it — for a shared set, the full link is best;
• your name, address, telephone number, and email address;
• a statement that you believe in good faith that the use is not authorised by the copyright owner, its agent, or the law; and
• a statement that the information in your notice is accurate and, under penalty of perjury, that you are the copyright owner or are authorised to act on the owner's behalf.

A notice missing these elements may not be effective. Under United States law you can be liable for damages, including costs and legal fees, if you knowingly misrepresent that material is infringing.

What we do when we receive one. We review the notice, and if it is valid we remove the material from public view promptly. We tell the person who published it that we have done so and why, and we send them a copy of your notice, including the contact details in it — that is how the process works, so please do not put anything in a notice that you are not willing for them to see.

If we removed your set and you think that was a mistake. You can send us a counter-notice at the same address. It must contain your signature; identification of the set that was removed and where it appeared; a statement under penalty of perjury that you believe in good faith it was removed as a result of a mistake or a misidentification; and your name, address and telephone number, together with a statement that you consent to the jurisdiction of the United States federal court for the district where you live, or — if you live outside the United States — of any United States federal court in which we may be found, and that you will accept service of process from the person who sent the original notice. We forward your counter-notice to them. If they do not tell us within ten business days that they have gone to court, we may restore the set, usually between ten and fourteen business days after we receive your counter-notice.

Repeat infringement. We keep a record of the copyright notices we act on. In appropriate circumstances we terminate the accounts of people who repeatedly publish material that infringes other people's copyright, and we may do so without warning. Publishing material you do not have the right to publish also breaches Section 11.

Where to send it. Send copyright notices and counter-notices to copyright@moozgy.com.

14. Acceptable use

You agree not to: (a) submit email addresses or account information you do not own or control; (b) use bots, scripts, or automation to sign up, claim spots, solve problems, manipulate the counter, the leaderboard, or the referral system; (c) probe, disrupt, overload, or interfere with the website, the app, or its providers; (d) misrepresent your affiliation with Moozgy; or (e) use the website or the app for any unlawful purpose. We may refuse, revoke, or cancel accounts, sign-ups, and benefits obtained in violation of this section, and (for purchases obtained fraudulently) treat the purchase as void, subject to Apple's own policies for in-app purchases.

15. Community and safety

Moozgy has social features: a public handle, leaderboards, a friends list and a friend activity feed. There is no tolerance for objectionable content, or for abusive behaviour towards other people on Moozgy.

Your handle is the one thing you write that other users see. It must not be obscene, hateful, sexually explicit, harassing or a slur; must not impersonate another person, a brand, or Moozgy itself; and must not otherwise be objectionable. We may reject or reset a handle that breaks this rule.

You may not use the social features to harass, threaten, intimidate or abuse anyone.

Reporting and blocking. Anywhere Moozgy shows you another person — the Ranks boards, Find friends, your friends list, and a person's profile — you can report them, and you can block them. Blocking removes them from everything you see, and removes you from everything they see. You can also report an answer written by our AI features, and you can report a shared set that someone has published. Anyone can report a shared set, whether or not they use Moozgy, by writing to hello@moozgy.com. We read every report and act on it promptly.

Enforcement. Where this section is broken we may reset a handle, remove a published set from public view, remove other content, or suspend or permanently terminate an account, at our discretion and without prior notice. We also terminate the accounts of people who repeatedly publish material that infringes other people's copyright — see Section 13. Questions or appeals: hello@moozgy.com.

16. Disclaimer of warranties

THE WEBSITE, THE APP, AND ANY PRE-LAUNCH OFFER, SUBSCRIPTION, OR GIFT ARE PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT, AND WITHOUT ANY WARRANTY THAT THE WEBSITE OR APP WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF IMPLIED WARRANTIES, SO SOME OF THE ABOVE MAY NOT APPLY TO YOU.

17. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW: (a) MOOZGY WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, DATA, GOODWILL, OR OPPORTUNITY, ARISING OUT OF OR RELATING TO THE WEBSITE, THE APP, OR THESE TERMS, EVEN IF ADVISED OF THE POSSIBILITY; AND (b) MOOZGY'S TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS WILL NOT EXCEED THE GREATER OF THE AMOUNT YOU PAID TO MOOZGY IN THE 12 MONTHS BEFORE THE CLAIM AROSE OR US $20. THESE LIMITS DO NOT APPLY TO LIABILITY THAT CANNOT BE LIMITED BY LAW (INCLUDING LIABILITY FOR FRAUD, GROSS NEGLIGENCE, OR WILLFUL MISCONDUCT, OR FOR DEATH OR PERSONAL INJURY WHERE SUCH LIMITS ARE PROHIBITED). THE EXCLUSIVE REMEDY FOR DISSATISFACTION WITH THE WEBSITE OR THE APP IS TO STOP USING IT.

18. Dispute resolution — binding arbitration & class action waiver

Please read this section carefully — it affects your legal rights.

• Informal resolution first. Before filing any claim, you agree to email us a written description of the dispute and give us 30 days to resolve it informally.
• Binding individual arbitration. Any dispute, claim, or controversy arising out of or relating to the website, the app, any purchase, or these Terms that is not resolved informally shall be finally resolved by binding arbitration administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules, before a single arbitrator, conducted in English. The arbitration will be held remotely (by videoconference or documents-only) or, if an in-person hearing is required, in the county where you reside or another mutually agreed location. The Federal Arbitration Act governs the interpretation and enforcement of this section.
• Class action waiver. ALL CLAIMS MUST BE BROUGHT IN THE PARTIES' INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, COLLECTIVE, CONSOLIDATED, OR REPRESENTATIVE PROCEEDING. The arbitrator may not consolidate claims or preside over any form of class proceeding. If this waiver is found unenforceable as to a particular claim, that claim (and only that claim) shall proceed in court, and the rest shall be arbitrated.
• Exceptions. Either party may bring an individual claim in small-claims court, or seek injunctive relief in court for infringement or misuse of intellectual property.
• 30-day opt-out. You may opt out of this arbitration agreement and class waiver by emailing us (Section 21) within 30 days of first accepting these Terms, stating your name, the email you signed up or registered with, and your intent to opt out. Opting out does not affect any other part of these Terms.
• EU consumers. If you are a consumer habitually resident in the EU/EEA, nothing in this section deprives you of the protection of mandatory provisions of your local law or of recourse to your local courts or to the European Commission's Online Dispute Resolution platform where those rights cannot be waived.

19. Governing law

These Terms and any dispute arising out of them are governed by the laws of the State of California, USA, without regard to its conflict-of-law rules, except where the mandatory consumer law of your habitual residence applies and cannot be derogated from by agreement. Subject to Section 18, any claim not subject to arbitration shall be brought exclusively in the state or federal courts located in California, and the parties consent to their jurisdiction.

20. General provisions

• Changes. We may update these Terms prospectively; the "Last updated" date will change. Material changes affecting recorded sign-ups or active accounts will be notified by email. Continued use after changes constitutes acceptance; the terms in effect at the time of your purchase govern that purchase.
• Assignment. You may not assign these Terms. We may assign them, together with the data described in the Privacy Policy, to a company formed to operate the Moozgy business or in connection with a merger, acquisition, or sale of assets — your rights and promised benefits survive any such assignment.
• Severability. If any provision is held unenforceable, it will be modified to the minimum extent necessary, and the rest remain in effect.
• No waiver. Failure to enforce a provision is not a waiver of the right to enforce it later.
• Force majeure. We are not liable for delay or failure caused by events beyond our reasonable control.
• Entire agreement. These Terms and the Privacy Policy are the entire agreement between you and Moozgy regarding the website and the app, and supersede any prior understandings.
