MindyCards:
Terms of Service

1. Acceptance of these Terms

These Terms of Service form a binding agreement between you and MindyWorld OÜ (operating as MindyCore), an Estonian company registered under number 17339961, with registered address at Jõe tn 3-315, 10151 Tallinn, Estonia.

By downloading, installing, accessing, or using MindyCards (the “App”), you confirm that you have read, understood, and accepted these Terms. If you do not agree, please do not use the App.

2. Eligibility and minimum age

The App is intended for users aged 13 years or older. By using the App, you confirm that you are at least 13 years old.

If you are between 13 and the age of digital consent in your country (16 by default under the EU General Data Protection Regulation, with national variations: 13 in the UK, 14 in Spain and Italy, 15 in France, 16 in Germany and Estonia, and similar variations elsewhere), you confirm that you have explicit consent from a parent or legal guardian to use the App, and that your parent or guardian has reviewed and accepted these Terms on your behalf.

Children under 13 are not permitted to use the App under any circumstances. If we become aware that a user is under 13, we will close the account (where applicable) and delete any associated data without delay.

Parents and legal guardians are responsible for supervising the use of the App by minors under their authority, including reviewing these Terms and the Privacy Policy, configuring parental controls in the device (Apple Screen Time, Google Family Link, or equivalent), and supervising in-app purchases. MindyCore offers the technical and contractual framework, but parental supervision remains the responsibility of the parent or guardian.

3. Description of the App

MindyCards is a collection of traditional card games from different cultures, distributed free of charge on the Apple App Store and Google Play. The App offers two tiers:

Free tier: supported by non-personalized advertising served through Google AdMob. Account creation is optional but unlocks features such as progress synchronization across devices.

Premium tier: a recurring monthly subscription that removes all advertising. Premium requires account creation.

The free tier may include limits on how frequently certain games can be played, using an in-app resource system. Any such limits are shown in the App before you start a game. Premium removes advertising; the specific benefits of Premium are described in the App at the point of purchase.

Premium subscriptions are billed through your device’s app store (Apple App Store or Google Play), or, where offered, through our payment processor, in accordance with the applicable billing rules.

4. Account

To create an account in MindyCards you may use Sign in with Apple, Sign in with Google, or email-based registration. Authentication is managed through our identity system in combination with Firebase Authentication. You are responsible for keeping your credentials safe and for any activity carried out under your account.

You must promptly notify us at core@mindycore.com if you suspect unauthorized access to your account.

You may delete your MindyCards account at any time from the in-app Settings menu, or by contacting us at core@mindycore.com. Upon deletion, your personal data is removed within 30 days, except for records we are legally required to retain (for example, transactional records subject to Estonian and EU tax law for up to 7 years).

5. Premium subscription

MindyCards offers an optional Premium monthly subscription that removes advertising. The price, currency, and applicable taxes are displayed in the App before any purchase.

In-app purchases are charged through Apple’s In-App Purchase or Google Play Billing, as applicable, in accordance with their respective rules. Subscription entitlements are managed through RevenueCat. Where purchases are offered outside the app stores, payment is processed by Stripe.

Subscriptions renew automatically at the end of each billing period unless cancelled at least 24 hours before renewal. You may manage or cancel your subscription at any time from your Apple ID or Google Play account settings, or through the mechanism indicated at the time of purchase.

Refunds for purchases made through an app store are handled by that store according to its policies. MindyCore does not directly process refunds for subscriptions purchased through Apple or Google. For purchases made through Stripe, refund requests can be sent to core@mindycore.com.

EU consumers have a statutory right of withdrawal of 14 days under Directive 2011/83/EU on consumer rights. By purchasing a Premium subscription and starting to use it immediately, you expressly request immediate performance and acknowledge that you will lose your right of withdrawal once the service has been fully performed.

6. Virtual currency, in-app resources and cosmetics

MindyCards may include virtual currency (coins, gems), in-app resources that regulate access to certain games, and cosmetic items that you can earn through gameplay or, in the future, acquire through in-app purchases. Virtual items and resources have no real-world monetary value, cannot be exchanged for cash, and are not transferable between users or between accounts.

Virtual items are licensed to you for personal use within the App only. Your license terminates if your account is closed for any reason.

MindyCards does not include real-money gambling. All game outcomes are for entertainment only.

7. Acceptable use

You agree to use the App lawfully and respectfully. You must not:

Use the App for any illegal purpose or in a way that harms others.

All rights not expressly granted are reserved by MindyWorld OÜ.

10. Apple App Store and Google Play

If you download the App from the Apple App Store, you acknowledge that these Terms are concluded between you and MindyWorld OÜ only, and not with Apple Inc. Apple is not responsible for the App or its content. Apple’s standard end user license agreement (EULA) applies to your use of the App where required.

If you download the App from Google Play, you acknowledge that Google’s standard terms apply to the distribution of the App to your device, and that Google is not a party to these Terms beyond what Google’s own terms specify.

11. Disclaimer and limitation of liability

The App is provided “as is” and “as available” without warranties of any kind, express or implied, except those that cannot be excluded under mandatory applicable law (notably EU consumer law).

To the maximum extent permitted by law, MindyCore is not liable for indirect, incidental, special, consequential, or punitive damages, including loss of data, loss of profits, or loss of goodwill, arising from your use of the App.

MindyCore’s total liability arising from or in connection with these Terms or the App is limited to the greater of: (a) the total amount you paid for the App or its subscriptions during the twelve months preceding the event giving rise to the claim, or (b) fifty euros (EUR 50).

Nothing in these Terms limits or excludes our liability for fraud, gross negligence, death or personal injury caused by our negligence, or any liability that cannot be limited or excluded under mandatory applicable law. EU consumers retain all rights granted to them by EU and national consumer protection law.

12. Indemnity

To the extent permitted by applicable law, you agree to indemnify and hold harmless MindyWorld OÜ, its directors, employees, and contractors from any claims, damages, costs (including reasonable legal fees), and liabilities arising from: (a) your breach of these Terms, (b) your violation of applicable law, or (c) your infringement of any third-party right through your use of the App.

13. Suspension and termination

You may stop using the App at any time. You may delete your MindyCards account from the Settings menu at any time, and uninstall the App from your device.

We may suspend or terminate your access to the App if you materially breach these Terms or use the App in a way that creates legal risk for MindyCore or other users. Where reasonably possible and required by law, we will give you prior notice and an opportunity to remedy the breach.

Upon termination, the provisions of these Terms that by their nature should survive (including intellectual property, disclaimers, limitations of liability, indemnity, and governing law) will survive.

14. Changes to these Terms

We may update these Terms from time to time to reflect changes in our App, our business, or applicable law. Significant changes will be communicated through the App or by email (where applicable) at least 30 days before they take effect.

Continued use of the App after the effective date of the changes indicates acceptance. If you do not accept the new Terms, you may stop using the App and delete your account.

15. Governing law and dispute resolution

These Terms are governed by the laws of the Republic of Estonia and applicable laws of the European Union, without regard to conflict of law principles.

Disputes arising from these Terms or the App will be resolved in the competent courts of Tallinn, Estonia, unless mandatory consumer protection law in your country of residence grants you a different forum.

EU consumers may also use the European Online Dispute Resolution platform at ec.europa.eu/consumers/odr. Consumers outside the EU retain the legal rights granted by their local law.

16. Severability and full agreement

If any provision of these Terms is found to be invalid, illegal, or unenforceable, the remaining provisions will continue in full force. The invalid provision will be replaced by a valid provision that most closely reflects the original intent.

These Terms, together with our Privacy Policy, constitute the entire agreement between you and MindyCore regarding the App.
