1. Acceptance of these terms
By downloading, installing or playing MathMaker : Mind Challenge you agree to these Terms of Service and to our Privacy Policy. If you do not agree, please do not use the game.
2. Your licence
We grant you a personal, non-exclusive, non-transferable and revocable licence to use MathMaker : Mind Challenge for your own non-commercial entertainment. You may not copy, modify, reverse engineer, resell or create derivative works of the game or its content (including its questions).
3. Your progress
Your progress is saved only on your device. It is not backed up to our servers and cannot be moved to another device: uninstalling the game or switching devices starts the game from the beginning. Permanent purchases can be restored (see In-app purchases). Game Center and Google Play Games are used only for leaderboards and your player name.
4. Virtual items
Sigma (Σ), Epsilon (ε), lives, power-ups and other in-game items have no monetary value outside the game. They cannot be sold, transferred or exchanged for real money, and you receive only a limited licence to use them. We may adjust balances to fix errors, bugs or abuse.
5. In-app purchases
MathMaker : Mind Challenge is free to play and offers optional in-app purchases: consumable items (such as Epsilon packs, bundles and timed boosts) and permanent unlocks (such as Remove Ads and category unlocks). There are no subscriptions. Payments are charged to your Apple ID or Google Play account at confirmation, and refunds are handled by Apple or Google under their policies. Permanent unlocks can be restored at any time with Restore Purchases in the Store; consumable items cannot be restored once they have been delivered.
6. Advertising
The game shows ads, including optional rewarded ads that grant in-game items. Ad availability is not guaranteed. The Remove Ads purchase removes all ads except the optional rewarded ones.
7. Fair play
You agree not to cheat, use bots, scripts, modified clients or exploits, manipulate leaderboards or in-game currency, interfere with the game or its services, or use the game for any unlawful purpose. We may remove leaderboard entries or restrict access if these rules are broken.
8. Intellectual property
The game, its questions, design, artwork, text and software are owned by us or our licensors and protected by copyright and other laws. Game Center is a trademark of Apple Inc.; Google Play and Google Play Games are trademarks of Google LLC.
9. Disclaimer
MathMaker : Mind Challenge is provided “as is” and “as available”. We work hard to keep questions correct and the game running, but we do not guarantee that it will be error-free, uninterrupted or available at all times.
10. Limitation of liability
To the maximum extent permitted by law, we are not liable for any indirect, incidental, special or consequential damages, or for loss of data or progress, arising from your use of the game. Nothing in these terms limits rights you have as a consumer that cannot be excluded by law.
11. Changes and termination
We may update the game and these terms. Continued use after a change means you accept the new terms. We may suspend or end your access if you breach these terms, and you may stop using the game at any time by uninstalling it.
12. Apple and Google
These terms are between you and us, not Apple or Google. Apple and Google have no obligation to provide maintenance or support for the game and are not responsible for any claims relating to it. If you downloaded MathMaker : Mind Challenge from the App Store, Apple's standard Licensed Application End User License Agreement also applies, and Apple and its subsidiaries are third-party beneficiaries of these terms.
