Effective Date: 13.08.2026

This End User License Agreement (“Agreement”) is a legal agreement between you (“Player”) and the developer of DrainSim (“Developer”) regarding your use of the game DrainSim (“Game”).


You are granted a limited, non-exclusive, non-transferable license to download, install, and play the Game for personal, non-commercial use.

You may not:

* Copy, distribute, or resell the Game
* Modify, reverse-engineer, or decompile the Game, except as permitted by law or through official editing and modding tools provided by the Developer
* Use the Game for commercial purposes without written permission

User-generated content may be created and shared only as permitted under Section 4 of this Agreement.


All rights, title, and interest in the Game, including copyrights, trademarks, and other intellectual property rights, remain the property of the Developer or the respective third-party rights holders.

This Agreement does not transfer any ownership to you.


DrainSim includes Unreal® Engine technology.

Unreal® is a trademark or registered trademark of Epic Games, Inc. in the United States of America and elsewhere.

To the maximum extent permitted by applicable law, Epic Games, Inc., Epic Games Commerce GmbH, and their affiliates, licensors, and service providers make no representations, warranties, or conditions of any kind regarding Unreal Engine or any other Epic licensed technology included in the Game, and disclaim all liability arising from or related to such technology.

You may only use Unreal Engine technology as incorporated in DrainSim in object code form and only as an inseparable part of the Game. You may not extract, copy, modify, redistribute, sublicense, or use Unreal Engine technology separately from the Game.


The Game may allow you to create, import, upload, publish, download, and use custom levels and other user-generated content through the DrainSim Level Editor and the Steam Workshop. This includes level files, assets, preview images, titles, descriptions, and any accompanying files (“User Content”).

4.1 Upload Requirements

By uploading or publishing User Content, you confirm that:

* You created the User Content yourself or possess all rights and permissions required to use and distribute it
* The User Content does not violate applicable laws, the rights of third parties, this Agreement, or the applicable Steam rules
* The User Content does not contain malware, viruses, ransomware, spyware, trojans, malicious scripts, executable code, corrupted data, or other components intended to damage, disrupt, compromise, or gain unauthorized access to the Game, another user’s device, software, network, accounts, or data
* The User Content does not contain unauthorized personal information or infringe copyrights, trademarks, privacy rights, publicity rights, or other intellectual property rights
* The upload does not contain files unrelated to or unnecessary for the intended DrainSim level or modification
* The User Content is not falsely presented as official content created, approved, or endorsed by the Developer

You remain responsible for your User Content and for maintaining your own backup copies.

4.2 License to User Content

You retain ownership of any rights you hold in your User Content.

By uploading or publishing User Content, you grant the Developer a worldwide, non-exclusive, royalty-free license to host, store, reproduce, distribute, publicly display, test, moderate, technically modify, and promote that User Content as reasonably necessary to operate, improve, secure, distribute, and promote the Game, its Level Editor, and its Workshop features.

This license includes the right to make technical changes required for compatibility, security, moderation, or integration into the Game. Unless separately agreed in writing, you are not entitled to payment or other compensation for User Content.

Removal of User Content does not affect copies already lawfully downloaded by other users or material already incorporated into an official distribution or previously created promotional material, to the extent permitted by applicable law.

4.3 Moderation and Removal

The Developer may reject, report, restrict, disable, hide, or remove User Content, or request its removal by Valve, where the Developer reasonably considers this necessary for legal, security, moderation, compatibility, technical, or operational reasons, or because the User Content may violate this Agreement or applicable Steam rules.

Publication, visibility, continued availability, compatibility, and preservation of User Content are not guaranteed. Workshop features, supported file formats, and access to particular submissions may be changed or discontinued.

Valve may independently restrict or remove Workshop submissions under the Steam Subscriber Agreement, Steam Workshop Legal Agreement, and applicable Steam Community rules.

4.4 Third-Party User Content

Workshop content is created by third parties and is not necessarily reviewed, endorsed, or approved by the Developer.

To the maximum extent permitted by applicable law, the Developer does not guarantee that third-party User Content is accurate, functional, secure, compatible, or free from errors. The Developer may provide technical security measures but cannot guarantee that every harmful or defective submission will be detected.


The Developer may remove, reset, or invalidate leaderboard entries and restrict or revoke access to leaderboard features where reasonably necessary. This includes, but is not limited to, cases of cheating, exploitation, or submission of abnormal or manipulated gameplay data.

Leaderboard rankings and entries are not guaranteed to be accurate, complete, or permanent.


The Game may collect anonymized gameplay data through GameAnalytics to help improve performance, balance, and stability.

The Developer does not intentionally collect directly identifying personal data through GameAnalytics.

Steam features, including leaderboards and the Steam Workshop, may process Steam account identifiers, display names, submissions, and related interaction data. Processing performed by Valve is governed by Valve’s applicable privacy terms.

The Developer’s data processing is described in the Game’s Privacy Policy, which forms part of this Agreement.

You may opt out of analytics collection at any time by disabling analytics in the Game’s settings menu.

The Privacy Policy is available here: https://drainsim.com/drainsim_privacy.html


By playing the Game, you confirm that you are at least 13 years old, or meet the minimum legal age applicable in your country, or that you have permission from a parent or legal guardian.


This Agreement is effective until terminated. The Developer may revoke this license if you materially breach its terms.

Upon termination, you must stop using the Game and delete all copies under your control. Termination may also result in the restriction of access to Level Editor, Workshop, or leaderboard features.


The Game is provided “as is” without warranties of any kind, to the maximum extent permitted by applicable law.

The Developer does not guarantee uninterrupted gameplay, bug-free performance, continued compatibility, or the availability of online, Workshop, leaderboard, or Level Editor features.


To the fullest extent permitted by applicable law, the Developer is not liable for damages arising from the use of or inability to use the Game or third-party User Content.

Nothing in this Agreement excludes or limits liability where such exclusion or limitation is prohibited by applicable law.


This Agreement shall be governed by and construed under the laws of Germany.

Mandatory consumer-protection laws applicable in the Player’s country of residence remain unaffected.

If any provision of this Agreement is found invalid or unenforceable, the remaining provisions shall remain enforceable.

By installing or playing DrainSim, using the Level Editor, or uploading User Content, you agree to the terms of this Agreement.
