Terms of Service
These terms govern your use of the Cortex Brain Training app ("the app"). By downloading or using the app you agree to them. If you don't agree, please don't use the app.
1. Licence
We grant you a personal, non-exclusive, non-transferable, revocable licence to install and use the app on devices you own or control, for your own personal, non-commercial use, in accordance with the Apple App Store or Google Play terms you also accepted.
2. Purchases
The app is free to download with some games available at no cost. A single one-time in-app purchase unlocks all games permanently. All payments are processed by the Apple App Store or Google Play — we never handle your payment details. Refunds are governed by the relevant store's policies, not by us. The purchase is a one-time unlock; there is no subscription and no recurring charge.
3. No medical or health claims
The app is provided for practice and entertainment. It is not a medical device and is not intended to diagnose, treat, cure, or prevent any condition. We make no promise that using it will improve intelligence, memory, or any real-world outcome, or prevent cognitive decline. The classic puzzles (such as Sudoku and Word Search) are offered purely as puzzles.
4. Acceptable use
You agree not to:
- reverse-engineer, decompile, or attempt to extract the app's source code, except where permitted by law;
- redistribute, resell, or sublicense the app;
- use the app in any unlawful way or to infringe anyone's rights.
5. Your content
Documents you import into the Speed Reader remain yours and are processed only on your device (see our Privacy Policy). You are responsible for having the right to use any document you import.
6. Intellectual property
The app, its design, and its content are owned by us or our licensors and are protected by intellectual-property laws. These terms grant you a licence to use the app, not any ownership of it.
7. Disclaimer & limitation of liability
The app is provided "as is" and "as available", without warranties of any kind to the fullest extent permitted by law. To the maximum extent permitted by law, we are not liable for any indirect, incidental, or consequential damages arising from your use of the app. Nothing in these terms limits liability that cannot be limited under applicable law.
8. Changes
We may update these terms from time to time; the date at the top reflects the latest version. Continued use of the app after a change means you accept the updated terms.
9. Governing law
These terms are governed by the laws of the Netherlands, without regard to conflict-of-law rules. Mandatory consumer-protection rights in your country of residence still apply.
