Terms of Service

Effective date: 24 April 2026 · Last updated: 24 April 2026 · Version 1.0

1. Acceptance

By creating a Mindoria account, downloading, installing, or using the Mindoria mobile application or any related service available at mindoria.app (collectively, the "App"), you accept these Terms of Service ("Terms") and our Privacy Policy. These Terms form a binding agreement between you and the operator of Mindoria (the "Operator", "we", "us", or "our"). If you do not agree, do not create an account or use the App.

2. Definitions

In these Terms:

• "App" means the Mindoria mobile application and the website at mindoria.app.
• "Service" means the features the App provides, including lessons, spaced repetition, achievements, leaderboards, friends, and the game modes PvP (player-versus-player asynchronous trivia) and Rush (timed solo trivia).
• "User", "you", "your" means the natural person who registers an account.
• "Content" means lessons, teaching cards, curiosities, questions, images, audio, and any other material made available through the App.
• "Plus" and "Premium" are the paid subscription tiers offered through the applicable app store.

3. Eligibility

You must be at least 13 years old to create an account. In jurisdictions where the minimum age for digital consent is higher than 13 (for example, 16 in parts of the European Economic Area), the corresponding higher age applies. If you are under the age of majority in your jurisdiction, you may use the App only with the consent and supervision of a parent or legal guardian, who agrees to be bound by these Terms on your behalf.

By creating an account, you confirm that you meet the applicable age requirement.

4. Account registration & security

Using the App requires a free Mindoria account. There is no anonymous or guest mode. You may register using an email address and password, or by signing in with Google. Email addresses are verified via a one-time code; you must complete verification before some features become available.

You agree to provide accurate information, to keep one account per person, and to keep your credentials confidential. You are responsible for activity that occurs under your account. Tell us promptly at [email protected] if you suspect unauthorised access. The Operator is not liable for losses caused by your failure to safeguard your credentials.

You may recover access via the in-app password reset flow.

5. Permitted use & conduct

The App is provided for your personal, non-commercial use. You agree not to:

• copy, scrape, mirror, frame, reverse-engineer, decompile, or otherwise attempt to extract the App's source code or Content other than as permitted by mandatory law;
• use the App via automated means (bots, scripts, emulators) except where the Operator expressly permits accessibility tools;
• interfere with the Service, attempt to overload servers, probe for vulnerabilities, or circumvent rate limits or security features;
• impersonate another person or use a display name that is misleading, infringing, hateful, sexually explicit, or otherwise abusive;
• resell, sublicense, or commercially exploit the App or any part of it.

Fair play in PvP and Rush. Multi-accounting, ELO manipulation (including throwing matches or coordinating with opponents), exploiting bugs to inflate scores or rankings, and any form of cheating or collusion are prohibited. The Operator may reset scores, suspend matchmaking access, or terminate accounts found to be in breach.

6. User content

The App stores limited user-supplied content: your display name, optional avatar URL, and a unique friend code. These may be visible to other users (for example, opponents in PvP and Rush leaderboards, or people you add as friends).

You retain ownership of what you submit. You grant the Operator a non-exclusive, worldwide, royalty-free licence to display, transmit, store, and otherwise use your submissions solely as needed to operate and improve the Service. The licence ends when you delete your account, except for residual copies retained in routine system backups for the period described in Section 14.

You warrant that you have all rights necessary to submit anything you post, that it is not infringing, defamatory, or unlawful, and that it does not contain personal information of others without their consent. The Operator may remove any submission that breaches these Terms.

7. Subscriptions & paid tiers

Lessons, every subject, every game mode (including PvP and Rush), and the core Service are free. Mindoria offers two optional paid subscription tiers — Plus and Premium — that provide quality-of-life enhancements such as higher daily limits for PvP and Rush sessions, faster heart refills, additional weekly streak freezes, and a premium badge. Specific limits are documented in-app and may be adjusted at the Operator's discretion.

Billing. Subscriptions are sold and billed by the platform store on which you purchased — currently Google Play Store on Android, and Apple App Store on iOS when iOS becomes available. The Operator does not receive your payment-card details.

Auto-renewal. Subscriptions renew automatically at the end of each billing period at the then-current price unless you cancel before renewal. You may cancel auto-renewal at any time in your store account; cancellation takes effect at the end of the current paid period and you keep access until then.

Refunds. Refunds are handled by the platform store. See Google Play's refund policy for Android purchases and Apple's policy for iOS purchases. Where you are entitled to a statutory cooling-off period or other mandatory consumer right (for example, the 14-day right of withdrawal under EU law for first-time digital subscriptions), that right applies regardless of these Terms; the platform store handles its operation.

Free trials. If a free trial is offered, you will not be charged during the trial period, and you may cancel at any time before it ends to avoid being charged.

8. Virtual items

The App uses internal counters and game elements such as hearts, streaks, ELO ratings, Rush scores, achievements, and other in-app metrics. These items have no monetary value, are non-transferable, and cannot be redeemed for cash, goods, or services outside the App. The Operator may add, remove, modify, or reset any such item at any time, including for reasons of game balance, anti-cheating, or technical maintenance, without compensation.

9. Advertising

Mindoria shows opt-in rewarded advertisements only, served by Google AdMob, where you voluntarily watch a short ad in exchange for an in-app benefit (for example, refilling hearts). The App does not show banner or interstitial advertisements. Rewarded ads are configured as non-personalised by default. See the Privacy Policy for details on advertising data flows.

10. AI-generated content & educational disclaimer

Content available through the Service — including lessons, teaching cards, curiosities, and questions used in PvP and Rush — is created with the assistance of artificial-intelligence systems and reviewed editorially before publication, including a factual-verification pipeline. Despite this review, errors can occur.

The Service is intended for general educational and entertainment purposes only. It is not a substitute for professional advice. Do not rely on Content for consequential decisions in medical, legal, financial, or safety-critical matters; verify information with a qualified professional or an authoritative source. The Operator does not guarantee the accuracy, completeness, or currency of any Content.

11. Intellectual property

The App, the Service, and the Content (excluding your own user content under Section 6) are owned by the Operator or its licensors and are protected by copyright, trademark, and other intellectual-property laws. The Operator grants you a limited, personal, non-exclusive, non-transferable, revocable licence to use the App on devices you own or control, solely for non-commercial use in accordance with these Terms. All rights not expressly granted are reserved.

"Mindoria" and the Mindoria fox logo are trademarks of the Operator. You may not use them without prior written permission.

12. Third-party services

The App integrates with third-party services that have their own terms and privacy policies, including:

• Google Play Billing — payment processing on Android.
• Apple App Store — payment processing on iOS, when available.
• RevenueCat — subscription state management.
• Google AdMob — rewarded ad serving.
• Firebase Cloud Messaging — push notifications.
• PostHog — product analytics.
• Resend — transactional email delivery.

The Operator is not responsible for third-party services. Your use of them is subject to the respective provider's terms.

13. Privacy

Information about how we collect, use, and protect your personal data is set out in our Privacy Policy. By using the App you acknowledge that you have read it.

14. Termination

By you. You may stop using the App at any time. To delete your account, open the App, go to Settings → Delete account, and confirm. Deletion is immediate and irreversible: it removes your profile, progress, XP, streak, hearts, friendships, PvP and Rush history, and achievements from our active systems. Residual copies of your data may persist in routine system backups for up to 60 days, after which they are purged. The Operator does not maintain user-recoverable backups; once your account is deleted, your access cannot be restored.

By the Operator. We may suspend or terminate your access, with or without notice where reasonable, if you breach these Terms — including but not limited to fraud, payment chargebacks, PvP or Rush cheating, abusive conduct toward other users, attempts to circumvent the Service, or where required by law. We will give you reasonable notice and, where practical, an opportunity to remedy the breach unless doing so would prejudice the rights of others or compromise security.

Active subscription benefits cease on termination. Mandatory consumer-protection rights (including any pro-rata refund obligations under applicable consumer law) are preserved.

15. Disclaimer of warranties

The App and the Content are provided "as is" and "as available". To the fullest extent permitted by law, the Operator disclaims all warranties, express or implied, including warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy of Content, uninterrupted availability, and freedom from defects or harmful components. Nothing in this section limits warranties that cannot be excluded under mandatory consumer-protection law in your country of residence.

16. Limitation of liability

To the fullest extent permitted by law, the Operator's total aggregate liability arising out of or in connection with these Terms or your use of the App is limited to the greater of (a) the amount you paid the Operator in subscription fees in the twelve months preceding the event giving rise to the claim, or (b) any minimum amount required by mandatory law. The Operator is not liable for indirect, incidental, special, consequential, or punitive damages, or for loss of profits, data, goodwill, or opportunity, even if advised of the possibility of such damages.

Nothing in these Terms excludes or limits liability for death or personal injury caused by negligence, fraud, fraudulent misrepresentation, or any other liability that cannot be limited under applicable law (including mandatory consumer-protection minimums under the Brazilian Consumer Defence Code, EU consumer-protection law, the UK Consumer Rights Act, and equivalent statutes).

17. Indemnification

You agree to indemnify and hold the Operator harmless from any third-party claims, damages, and reasonable costs (including legal fees) arising from (a) your breach of these Terms, (b) your misuse of the App, or (c) Content you submitted that infringes third-party rights. The Operator will notify you of any such claim and cooperate reasonably in its defence. This obligation does not apply to the extent a claim arises from the Operator's own breach or wilful misconduct.

18. Changes to these Terms

The Operator may update these Terms from time to time. For material changes we will notify registered users by email at least 30 days before they take effect; continued use of the App after the effective date constitutes acceptance. If you do not agree to a material change, you may terminate your account before the effective date without penalty. For minor changes that do not affect your rights (typo fixes, locale corrections), we may update the document silently and update the "Last updated" date.

19. Governing law & disputes

These Terms are governed by the laws of the Federative Republic of Brazil, without regard to its conflict-of-laws principles. Subject to the next paragraph, any dispute arising out of or in connection with these Terms shall be brought exclusively before the courts of the Comarca de São Paulo, State of São Paulo, Brazil.

Consumer carve-out. If you are a consumer resident in the European Economic Area, the United Kingdom, Brazil, or another jurisdiction whose mandatory consumer-protection law grants you the right to bring proceedings in the courts of your place of residence or to rely on the law of your habitual residence, those rights are preserved and these Terms do not derogate from them. Small-claims and equivalent low-value civil tribunals remain available where local law provides.

20. Apple App Store addendum

This section applies only when you obtain the App through the Apple App Store. It does not currently take effect because Mindoria is not yet available on iOS; it will apply automatically upon iOS launch.

• These Terms are concluded between you and the Operator only, and not with Apple Inc. ("Apple"). The Operator (not Apple) is solely responsible for the App and its Content.
• Apple has no obligation to provide maintenance or support for the App.
• If the App fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any) of the App. To the maximum extent permitted by law, Apple has no other warranty obligation with respect to the App.
• The Operator is solely responsible for addressing any claims relating to the App, including (but not limited to) product-liability claims, claims that the App fails to conform to legal requirements, and claims arising under consumer-protection or similar law.
• If a third party claims that the App or your possession and use of the App infringes that party's intellectual-property rights, the Operator (not Apple) is solely responsible for the investigation, defence, settlement, and discharge of any such claim.
• You represent and warrant that you are not located in a country subject to a U.S. Government embargo, or that has been designated by the U.S. Government as a "terrorist supporting" country, and that you are not on any U.S. Government list of prohibited or restricted parties.
• You must comply with applicable third-party terms of agreement when using the App, including the Apple Media Services Terms and Conditions.
• Apple and Apple's subsidiaries are third-party beneficiaries of these Terms, and upon your acceptance of these Terms Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.

21. Region-specific notices

European Economic Area / United Kingdom. If you are a consumer resident in the EEA, Switzerland, or the United Kingdom, you have a statutory right to withdraw from a first-time digital-content subscription within 14 days without giving any reason, except where you have given express prior consent to immediate performance of the contract and acknowledged that you thereby lose your right of withdrawal. Refunds in this scope are processed by the platform store. Nothing in these Terms affects your rights under your local consumer-protection law, including under the EU Consumer Rights Directive (2011/83/EU), the UK Consumer Rights Act 2015, the EU Digital Content Directive (2019/770), or the General Data Protection Regulation as it applies to your personal data.

Brazil. If you are a consumer resident in Brazil, your rights under the Código de Defesa do Consumidor (Lei nº 8.078/1990) and the Lei Geral de Proteção de Dados (Lei nº 13.709/2018) apply in full, including the right to clear pre-contractual information, the right to refund within seven days for purchases made outside an establishment, and the right to bring proceedings in the courts of your domicile.
