TERMS OF SERVICE FOR THE "WATERSORT: TUBE COLOR SORT" MOBILE APP

Last updated: November 7, 2026

1. General Provisions

1. These Terms of Service ("Terms") govern the use of the "WaterSort: Tube Color Sort" mobile application ("App") provided by MatCode Mateusz Arczyński, a sole proprietorship operating as MatCode Mateusz Arczyński, ul. Portowa 10, 86-200 Chełmno, Poland, NIP 875-156-25-99, REGON 383604557, e-mail: matcode.help@gmail.com ("Provider").

2. The App is a puzzle game in which the User sorts colored liquid between tubes. It offers, among other things, procedurally generated levels, a daily challenge with an archive, hints, stars and records, statistics, achievements and optional progress sync through Apple Game Center or Google Play Games.

3. By installing or starting to use the App, the User enters into an agreement with the Provider for electronic services on the terms set out here. Before using the App the User must read the Terms. Without acceptance the App may not be used.

4. Using the App does not require an account with the Provider. Personal data processing is described in the Privacy Policy.

2. Technical Requirements

1. Correct operation requires a mobile device running:

a) Android 7.0 (API 24) or newer, or

b) iOS 15.0 or newer,

and an optional Internet connection (needed only to show ads, sync progress, unlock achievements and download updates - the game itself works offline).

2. Progress sync and achievements require the User to be signed in to Apple Game Center (iOS) or Google Play Games (Android) and, on iOS, to have iCloud enabled. Without them the App works fully, with progress stored only on the device.

3. The Provider does not guarantee correct operation on devices that have been jailbroken, rooted or modified with custom software. This may expose the device to malware and compromise security features.

3. License and Intellectual Property Rights

1. The Provider grants the User a non-exclusive, non-transferable, revocable license to use the App solely for its intended purpose and in accordance with the Terms.

2. The User is in particular prohibited from:

copying or modifying the App or its parts (including the Provider's trademarks);
reverse engineering, decompiling, attempting to extract source code or translating the App - except to the extent mandatory law permits;
creating derivative works based on the App;
manipulating progress, records or achievements through modified software or data;
removing, bypassing or interfering with consent and ad mechanisms in a way that infringes third-party rights;
using the Provider's trademarks in a way contrary to law or good practice.

3. All intellectual property rights in the App (including trademarks, graphics, sounds, copyrights and database rights) remain with the Provider.

4. Game Progress and Cloud Sync

1. Progress is stored on the User's device. Uninstalling the App, clearing its data, device failure, loss or replacement may cause permanent loss of progress, unless it has been saved in the cloud with Apple Game Center or Google Play Games.

2. When the User is signed in to Apple Game Center or Google Play Games and syncing is on, the App saves a copy of the progress in that service's cloud and merges progress from several devices. These services are provided by Apple and Google under their own terms; the Provider does not guarantee their availability or that every change is saved immediately. The User can turn syncing off and delete the cloud save in the App's settings.

3. Achievements, stars and records have no monetary value and cannot be exchanged for money or other benefits.

5. Rules of Use and Liability

1. The App is an entertainment product. The Provider strives for the App to work correctly but does not guarantee uninterrupted or error-free operation, the availability of the daily challenge on a given day or the continuity of a daily streak (which depends, among other things, on the device date and time). To the extent permitted by law, the Provider is not liable for:

effects resulting from lack of, or limited, Internet access;
loss of progress in the situations described in section 4;
the operation of Apple Game Center, iCloud or Google Play Games;
damage caused by the User's breach of the Terms.

2. The above limitations do not exclude or limit liability that cannot be excluded or limited under mandatory law, including statutory consumer rights.

3. When using the Internet outside Wi-Fi, the User bears data costs under their mobile plan. If the User is not the bill payer of the device, they should have the payer's permission to use the App.

6. Advertising and Third-Party Services

1. The App is funded by banner ads served by Google AdMob. Ads may be personalized only with the User's consent, given in the consent form (UMP) and, on iOS, the App Tracking Transparency prompt. See the Privacy Policy for details. The Provider is not responsible for the content of third-party ads or advertisers' products and services.

2. The App uses third-party services that set their own terms. Terms of the services used:

7. Fees

1. The App is provided free of charge. The Provider reserves the right to introduce fees for the App or selected features in the future (e.g. ad removal), with reasonable advance notice clearly stating what is charged. Consumer rights acquired earlier are not reduced.

8. Updates and Termination

1. The Provider may release updates improving security, functionality or performance, including changes to levels and the daily challenge. System requirements may change; to keep using the App the User may need to install an update.

2. The Provider does not guarantee that the App will always be updated for compatibility with every OS version.

3. The Provider may discontinue the App or parts of it (including progress sync or achievements), subject to rights under mandatory law. Upon termination the license expires and the User should stop using the App and, if necessary, remove it from the device.

4. The User may stop using the App at any time by uninstalling it. The Provider may block or restrict access in case of a serious breach of the Terms.

9. Complaints

1. Complaints about the App may be sent to matcode.help@gmail.com, describing the problem and stating the device model, OS version and App version.

2. The Provider will respond to a complaint within 14 days of receipt, at the e-mail address it was sent from.

10. Amendments to Terms

1. The Provider may amend the Terms for valid reasons, in particular changes in law, App functionality or distribution-platform requirements. The amended Terms will be made available in the App or at https://matcode.eu/hub/watersort/terms-en.html at least 7 days before taking effect, unless the change results from mandatory law.

2. Continued use of the App after the changes take effect means acceptance. A User who disagrees may stop using the App.

11. Final Provisions and Contact

1. Matters not regulated by the Terms are governed by Polish law, subject to mandatory consumer-protection provisions of the consumer's country of residence.

2. Disputes with business users are resolved by the court competent for the Provider's seat. Consumers may use out-of-court dispute resolution, including mediation, local consumer ombudsmen or consumer protection authorities, and may bring claims before the court competent under general rules.

These Terms take effect on November 3, 2026.
