Terms of Use
1. Who we are and what these terms cover
Synaplay is a cognitive training application for iPhone, published by Yong Liu, an individual developer ("we", "us"). These Terms of Use form an agreement between you and us for the use of the Synaplay app and the website synaplay.toai.pro. If you obtained the app through the Apple App Store, these terms supplement, and incorporate by reference, Apple's Licensed Application End User License Agreement (the "Standard EULA"). If any provision in these terms conflicts with the Standard EULA, these terms control only for the subject they address.
2. Eligibility
You must be at least 13 years old to use Synaplay (or the minimum digital-consent age in your country). If you are a minor under the age of digital consent in your jurisdiction, use the app only with a parent's or guardian's permission.
3. Your license
We grant you a personal, non-exclusive, non-transferable, revocable license to use Synaplay on Apple-branded devices that you own or control, as permitted by the Usage Rules in the Apple Media Services terms. You may not copy, resell, redistribute, or attempt to extract the app's source code, except to the extent the law permits despite this limitation.
4. What Synaplay is, and is not
Synaplay offers games, assessments, and coaching designed to make daily cognitive practice enjoyable. It is a training and education product. It is not a medical device and does not diagnose, treat, cure, or prevent any disease or condition, and it is not a substitute for professional medical or psychological advice. Scores such as "brain age" are motivational training signals that respond to speed, accuracy, sleep, and fatigue; they are not clinical measurements.
5. Purchases and subscriptions
Synaplay is free to download and use: every game, the daily training plan, and every assessment can be used without paying. An optional upgrade, Synaplay Pro, is offered through Apple's in-app purchase system and removes the free tier's usage limits (an energy meter that refills over time), so you can practice without waiting. Pro is available as auto-renewing subscriptions (monthly and yearly) and as a one-time lifetime purchase.
- Billing. Payment is charged to your Apple ID at confirmation of purchase. All billing is handled by Apple; we never see your payment details.
- Renewal and cancellation. Subscriptions renew automatically unless they are cancelled at least 24 hours before the end of the current period. You will be charged for renewal within 24 hours before the current period ends. You can manage or cancel your subscription anytime in your App Store account settings.
- Prices. Prices and periods for your region are displayed in the app before you confirm a purchase; because they are set in App Store Connect and displayed live from Apple, they may change from time to time.
- Refunds. Refund requests are handled by Apple under its policies (for example via reportaproblem.apple.com); we are unable to issue refunds ourselves.
- Restoring purchases. If you reinstall the app or change devices, use the "Restore Purchases" button in the app (paywall or Settings), signed in with the same Apple ID.
6. Your content and data
Your training results, reports, and coach conversations live on your device under our Privacy Policy, and you own them. When you share a report card, what you share is yours. We receive none of it.
7. Acceptable use
- Do not misuse the app: no cheating automation intended to falsify results sold or shown to others, no reverse engineering beyond what the law allows, no interference with the website or its hosting.
- When you contact us by email, do not send confidential personal data; for anything sensitive, use the in-app erase instead.
8. Intellectual property
The Synaplay app, its games, engines, design, and the website content are owned by us and protected by intellectual property laws. The wordmark, mascot, and logo are our trademarks; nothing in these terms transfers any ownership to you. The app builds on openly licensed work, including the Nunito typeface (SIL Open Font License) and Phosphor Icons (MIT License), which remain under their own licenses. Apple, iPhone, Apple Intelligence, and the App Store are trademarks of Apple Inc.
9. Third-party services
The app relies on Apple platforms (App Store, iOS, Apple Intelligence when available). Your relationship with Apple, including purchase processing and on-device model processing, is governed by Apple's own terms and policies.
10. Disclaimers
Synaplay is provided "as is" and "as available" without warranties of any kind, whether express or implied, including warranties of merchantability, fitness for a particular purpose, and non-infringement, except as the Standard EULA and mandatory consumer law provide. We do not warrant that the app will be uninterrupted or error-free. Because your data lives on your device, backing up your device with iOS is how you back up your progress.
11. Limitation of liability
To the maximum extent permitted by law, our aggregate liability to you arising out of or relating to Synaplay is limited to the greater of the amount you paid us in the twelve months before the claim or fifty US dollars. We are not liable for indirect, incidental, special, consequential, or punitive damages, including lost data on a device you control or lost profits. Nothing in these terms limits liability for death or personal injury caused by negligence, for fraud, or for any liability that cannot be excluded under mandatory law, and nothing affects statutory consumer rights.
12. Indemnification
You agree to compensate us for third-party claims arising from your breach of these terms or your misuse of the app, to the extent permitted by law.
13. Termination
You can stop using Synaplay and erase your data at any time. We may end your license if you seriously breach these terms and do not remedy the breach after notice. Sections that by their nature should survive termination (intellectual property, disclaimers, liability) do survive.
14. Governing law and disputes
These terms are governed by the laws of the People's Republic of China, without regard to conflict-of-law rules, and the courts at the operator's domicile in the People's Republic of China have exclusive jurisdiction over any dispute, except that consumers may also bring claims in their country of residence under mandatory law. Nothing removes rights you hold under the consumer protection laws of your country of residence.
15. Changes to these terms
We may update these terms as the product evolves. The current version always lives on this page with an updated effective date, and material changes will be highlighted in the app or on the website before they take effect. Continuing to use Synaplay after changes take effect means you accept the updated terms.
16. General
If a court finds any provision unenforceable, the rest stays in force. We may assign this agreement as part of a merger or sale of assets. These terms, the Standard EULA, and our Privacy Policy are the entire agreement between you and us for Synaplay.
