9×16 — Expanding Tic-Tac-Toe

1. Agreement

These Terms of Service ("Terms") form a binding agreement between you and TE and CO, LDA ("we", "us", "our") regarding your use of the mobile application 9×16 — Expanding Tic-Tac-Toe (the "App"), distributed through the Apple App Store and Google Play.

By downloading, installing, or using the App you confirm that you have read, understood, and agreed to these Terms and to our Privacy Policy. If you do not agree, do not use the App.

2. License

We grant you a personal, non-transferable, revocable, non-exclusive license to install and use the App on devices that you own or control, solely for your personal, non-commercial use, subject to these Terms and to the rules of the platform from which the App was obtained.

The App is licensed, not sold. We retain all right, title, and interest in and to the App, including all intellectual property rights.

3. Apple App Store EULA

If you obtained the App from the Apple App Store, your use is also subject to Apple's Standard EULA for Licensed Application End User License Agreement. To the extent these Terms conflict with that EULA, the EULA controls only between you and Apple. Apple is not a party to these Terms and is not responsible for the App or its content.

4. Free and Pro Features

The App offers two free modes that anyone can play without payment:

• Single Player — you versus an AI on an expanding board.
• Time Attack — a 90-second score-chase mode.

The following modes require an active 9×16 Pro subscription:

• Hot Seat — two players, one device
• Blitz — 3-second or 5-second per-move mode
• Defender — draws count as a player win
• Survival — escalating boards, one loss ends the run
• Online — remote multiplayer over Firebase Realtime Database

5. Subscription — 9×16 Pro

a) Billing

Payment is charged to your Apple ID or Google Play account at confirmation of purchase. The subscription automatically renews each month unless you cancel at least 24 hours before the end of the current billing period. Each renewal charges your account at the then-current price.

b) Cancellation

You can cancel at any time. Cancellation takes effect at the end of the current billing period — you keep access to Pro features until then.

• iOS: Settings → Apple ID → Subscriptions → 9×16 Pro → Cancel.
• Android: Google Play → Account → Payments & subscriptions → Subscriptions → 9×16 Pro → Cancel.

c) Free trials and introductory offers

If we offer a free trial or introductory price, the duration and terms of the offer are displayed in the App and on the store before you confirm. Any unused portion of a free trial is forfeited when you purchase the subscription, where applicable, in accordance with Apple's and Google's policies. After the trial ends, the subscription automatically converts to a paid subscription at the regular price unless you cancel beforehand.

d) Refunds

Refund requests are handled by the platform that processed your payment, not by us:

• Apple: reportaproblem.apple.com
• Google: support.google.com/googleplay/answer/2479637

Apple and Google grant refunds at their sole discretion under their respective policies.

e) Family Sharing

Family Sharing is not enabled for the Pro subscription at launch. We may enable it in a future release.

f) Price changes

If we change the renewal price of the subscription, we will notify you in advance through the platform's standard mechanisms. Continued use after the change takes effect constitutes acceptance of the new price; you may cancel at any time before the new price is charged.

6. Acceptable Use

You agree not to:

• Reverse engineer, decompile, disassemble, or otherwise attempt to derive source code from the App, except to the extent permitted by applicable law
• Modify, adapt, translate, or create derivative works of the App
• Remove, alter, or obscure any proprietary notices in the App
• Use the App to transmit malicious code, attempt to disrupt our services, or gain unauthorised access to other accounts
• Use any automated system (bot, script) to play online matches or interact with online features
• Harass, threaten, or abuse other players in online matches
• Use the App in any manner that violates applicable law

We reserve the right to suspend or terminate access to online features (and to refuse service) for accounts that engage in any of the above.

7. User-Generated Content in Online Matches

Online matches identify each player by an anonymous Firebase user ID and, optionally, by the display name and photo associated with a Sign in with Apple or Google account that the player has linked. By linking such an account, you consent to your display name and photo being shown to your opponent in a match. We do not store match logs or chat content beyond what is needed to run the match in real time.

8. Updates and Availability

We may release updates to the App to fix bugs, improve performance, or add features. Some updates may be required for the App to continue to function correctly. We are not obligated to provide updates and we may discontinue the App or any of its features at any time.

Online features depend on third-party services (notably Google Firebase). We do not guarantee uninterrupted availability and we are not responsible for outages caused by those third parties.

9. Intellectual Property

The App, including its code, design, graphics, text, sounds, and trademarks, is owned by TE and CO, LDA and its licensors and is protected by copyright, trademark, and other laws. Nothing in these Terms grants you any right or license to use any of our trademarks or trade dress without our prior written permission.

10. Disclaimers

The App 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, non-infringement, or that the App will be uninterrupted, error-free, or free of harmful components. Some jurisdictions do not allow the exclusion of certain warranties, in which case those exclusions do not apply to you.

11. Limitation of Liability

To the maximum extent permitted by applicable law, in no event shall TE and CO, LDA, its directors, employees, or affiliates be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, revenue, data, or goodwill, arising out of or in connection with your use of the App, even if we have been advised of the possibility of such damages. Our total aggregate liability for any claim arising under these Terms shall not exceed the greater of (a) the amount you paid us for the App in the twelve months preceding the claim or (b) USD 50.

12. Indemnification

You agree to defend, indemnify, and hold harmless TE and CO, LDA from and against any claims, damages, liabilities, and expenses (including reasonable attorneys' fees) arising out of your breach of these Terms or your misuse of the App.

13. Termination

We may suspend or terminate your access to the App or to online features at any time for breach of these Terms. You may stop using the App at any time. The provisions that by their nature should survive termination (intellectual property, disclaimers, limitation of liability, governing law) survive termination of these Terms.

14. Governing Law and Jurisdiction

These Terms are governed by the laws of Portugal, without regard to its conflict-of-laws rules. The courts of Lisbon, Portugal, shall have exclusive jurisdiction over any dispute arising out of or relating to these Terms, except that nothing in these Terms shall prevent us from seeking injunctive relief in any court of competent jurisdiction. Where mandatory consumer-protection laws of your country grant you additional rights, those rights are not waived.

15. Changes to These Terms

We may update these Terms from time to time. When we make material changes, we will update the "Effective date" at the top of this page and, where appropriate, notify you through the App or the store listing. Continued use of the App after a change takes effect constitutes acceptance of the updated Terms.
