Terms & Conditions

Last updated: 2026-04-18

These terms and conditions apply to the DiffDiff app (hereby referred to as "Application") for mobile devices that was created by Pixel Port LLC, a company registered in Florida, United States, located at 7901 4TH ST N STE 300, ST. PETERSBURG, FL 33702 (hereby referred to as "Service Provider") as a Free service.

Upon downloading or utilizing the Application, you are automatically agreeing to the following terms. It is strongly advised that you thoroughly read and understand these terms prior to using the Application. Unauthorized copying, modification of the Application, any part of the Application, or our trademarks is strictly prohibited. Any attempts to extract the source code of the Application, translate the Application into other languages, or create derivative versions are not permitted. All trademarks, copyrights, database rights, and other intellectual property rights related to the Application remain the property of the Service Provider.

The Service Provider is dedicated to ensuring that the Application is as beneficial and efficient as possible. As such, they reserve the right to modify the Application or charge for their services at any time and for any reason. The Service Provider assures you that any charges for the Application or its services will be clearly communicated to you.

The Application processes gameplay data on your device. It is your responsibility to maintain the security of your device and access to the Application. The Service Provider strongly advises against jailbreaking or rooting your phone, which involves removing software restrictions and limitations imposed by the official operating system of your device. Such actions could expose your phone to malware, viruses, malicious programs, compromise your phone's security features, and may result in the Application not functioning correctly or at all.

Eligibility

You must be at least 13 years old to use the Application. By using the Application, you represent and warrant that you meet this minimum age requirement. If you are under the age of majority in your jurisdiction, you represent that your parent or legal guardian has reviewed and agreed to these Terms on your behalf.

What the Application Does

DiffDiff is a visual-discrimination puzzle game. You are shown a grid of tiles and asked to tap the single tile that differs from the rest within a time limit, across puzzle modes that test perception of color, characters, shapes, patterns, symmetry, and words. The Application includes a campaign, a daily challenge, freeplay variants, streaks, a hint economy, and optional real-time 1v1 matches via Apple Game Center.

No Health, Medical, or Cognitive Claims

DiffDiff is a game intended for entertainment. The Service Provider makes no representation that the Application will improve memory, intelligence, cognition, concentration, academic or work performance, eyesight, or general brain health, and makes no representation that it will diagnose, treat, prevent, cure, or mitigate any disease, disorder, or condition (including but not limited to dementia, Alzheimer's disease, ADHD, or any visual or neurological condition). The Application is not a medical device, is not intended as a substitute for professional medical advice or treatment, and should not be relied upon for any therapeutic, diagnostic, clinical, or educational purpose. You agree to use the Application solely for entertainment.

Third-Party Services

The Application integrates with services provided by Apple. These services are governed by Apple's own terms:

• Apple iCloud Terms of Service (for iCloud / CloudKit sync)
• Apple Game Center Terms (for leaderboards, achievements, and 1v1 matches)
• Apple Media Services Terms and Conditions (governing the App Store license)

The Application does not use any third-party analytics, advertising, or attribution services.

Game Center and Head-to-Head Matches

If you sign into Game Center, your display name and gameplay metrics (such as scores) will be visible to other players on leaderboards and during matches. You agree not to cheat, use unauthorized third-party tools, or submit scores using automated means. The Service Provider may request that Apple remove scores or accounts engaged in such conduct.

During 1v1 matches, match state (random seeds, round correctness, reaction time, score, and combo multiplier) is transmitted directly between the two matched devices via Apple's Game Center relay. The Service Provider does not operate the relay and does not receive this data.

User-Initiated Sharing

The Application may let you share a puzzle challenge link or a scorecard image via Apple's system share sheet. You are responsible for what you choose to share, with whom, and through which channel. Shared links and images may contain your score and (if you are signed into Game Center) your Game Center display name.

Purchases

The Application is currently offered free of charge, without in-app purchases, subscriptions, or advertising. If in-app purchases, subscriptions, rewarded advertising, or other paid features are added in a future release, they will be processed by Apple through the App Store under Apple's terms, will be clearly described at the point of purchase, and a corresponding section will be added to these Terms before such features are enabled.

Acceptable Use

You agree that you will not:

• modify, reverse engineer, decompile, or disassemble the Application except to the extent permitted by applicable law;
• use the Application or its leaderboards to harass, defame, impersonate, or harm other players;
• choose a display name that is obscene, infringing, impersonating, or otherwise unlawful;
• attempt to gain unauthorized access to the Application, other users' data, or Apple services;
• use automated scripts, bots, or tools to interact with the Application or manipulate scores;
• use the Application in violation of any applicable law or regulation.

Connectivity and Device Responsibility

Some functions of the Application (such as iCloud sync and Game Center features) require an active internet connection, which can be Wi-Fi or provided by your mobile network provider. The Service Provider cannot be held responsible if the Application does not function at full capacity due to lack of access to Wi-Fi or if you have exhausted your data allowance.

If you are using the Application outside of a Wi-Fi area, please be aware that your mobile network provider's agreement terms still apply. Consequently, you may incur charges from your mobile provider for data usage during the connection to the Application, or other third-party charges. By using the Application, you accept responsibility for any such charges, including roaming data charges if you use the Application outside of your home territory without disabling data roaming. If you are not the bill payer for the device on which you are using the Application, we assume that you have obtained permission from the bill payer.

Similarly, the Service Provider cannot always assume responsibility for your usage of the Application. For instance, it is your responsibility to ensure that your device remains charged. If your device runs out of battery and you are unable to access the Service, the Service Provider cannot be held responsible.

Updates and Termination

The Service Provider may wish to update the Application at some point. The Application is currently available as per the requirements for the operating system (and for any additional systems they decide to extend the availability of the Application to) may change, and you will need to download the updates if you want to continue using the Application. The Service Provider does not guarantee that it will always update the Application so that it is relevant to you and/or compatible with the particular operating system version installed on your device. However, you agree to always accept updates to the Application when offered to you. The Service Provider may also wish to cease providing the Application and may terminate its use at any time without providing termination notice to you. Unless they inform you otherwise, upon any termination, (a) the rights and licenses granted to you in these Terms will end; (b) you must cease using the Application, and (if necessary) delete it from your device.

Disclaimers and Limitation of Liability

The Application is provided "AS IS" and "AS AVAILABLE" without warranty of any kind, whether express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, and non-infringement. To the maximum extent permitted by applicable law, the Service Provider shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits or revenues, whether incurred directly or indirectly, or any loss of data, use, goodwill, or other intangible losses, resulting from your use of the Application.

Governing Law

These Terms are governed by the laws of the State of Florida, United States, without regard to its conflict of laws principles. You agree that any dispute arising out of or relating to these Terms or the Application will be resolved in the state or federal courts located in Florida, United States, and you consent to the personal jurisdiction of such courts.

Changes to These Terms and Conditions

The Service Provider may periodically update these Terms and Conditions. Therefore, you are advised to review this page regularly for any changes. The Service Provider will notify you of any changes by posting the new Terms and Conditions on this page.

These terms and conditions are effective as of 2026-04-18.
