# Ruin Upon Ruin End User License Agreement
**Effective date:** 26 August 2026
**Version:** 1.0
This End User License Agreement (the **“Agreement”**) is between you and
**Sanghun Moon**, an independent game developer publishing as an individual
(**“Licensor,” “we,” “us,”** or **“our”**), and governs your use of **Ruin Upon
Ruin**, including its software, content, updates, and related documentation
(collectively, the **“Game”**).
Please read this Agreement carefully. By acquiring, downloading, installing,
or using the Game, you agree to this Agreement. If you do not agree, do not use
the Game. You may request any available refund from the store or platform where
you acquired it, subject to that platform's rules and applicable law.
If you are not legally able to enter into this Agreement, a parent or legal
guardian must review and agree to it on your behalf. Additional age rules of
the platform through which you use the Game also apply.
## 1. Relationship with Steam and other platforms
If you acquire or use the Game through Steam, your use of Steam is separately
governed by the [Steam Subscriber
Agreement](https://store.steampowered.com/subscriber_agreement/), Steam's Rules
of Use, and [Valve's Privacy
Policy](https://store.steampowered.com/privacy_agreement/). Valve is not a
party to this Agreement. This Agreement governs your relationship with us
concerning the Game; the Steam terms govern your relationship with Valve and
your use of Steam.
The Game may require a valid platform licence and may require the relevant
platform client for installation, updates, verification, or platform features.
Some features may be unavailable when the platform or an Internet connection
is unavailable.
## 2. Limited licence
Subject to this Agreement and the rules of the platform through which you
acquired the Game, we grant you a limited, personal, non-exclusive,
non-transferable, non-sublicensable, and revocable licence to install and use
the Game on supported devices for your private, non-commercial entertainment.
The Game is licensed, not sold. Platform-authorised household or family-sharing
features may be used according to that platform's rules.
## 3. Restrictions
Except where this Agreement or applicable law expressly allows it, you must
not:
- copy, reproduce, distribute, publicly perform, sell, rent, lease,
sublicense, or otherwise commercially exploit the Game or any part of it;
- reverse engineer, decompile, disassemble, derive source code from, modify,
translate, or create derivative works from the Game;
- bypass or interfere with access controls, security features, platform
verification, or technical protection measures;
- use cheats, bots, automation, exploits, modified data, or unauthorised tools
to falsify scores, progression, achievements, or leaderboard results;
- extract or redistribute the Game's artwork, music, sound, text, code, or
other assets as standalone material;
- remove or alter copyright, trade mark, attribution, or other proprietary
notices; or
- use the Game unlawfully or in a way that infringes another person's rights.
These restrictions do not prohibit conduct that applicable law says cannot be
restricted, including any lawful interoperability, security-research, backup,
or reverse-engineering right that cannot be waived by contract.
## 4. Gameplay videos, streaming, and fan works
You may capture, publish, and monetise gameplay videos, livestreams,
screenshots, reviews, guides, and original fan works featuring the Game,
provided that you:
- do not distribute substantial Game assets separately or make a substitute
for the Game;
- do not imply that we sponsor or endorse you;
- follow the rules of the service on which you publish; and
- do not use our names or trade marks as the name or branding of your own
product, service, or business.
This permission is non-exclusive, may not be transferred, and does not grant
ownership of any Game content. It does not cover third-party material where a
third party's separate permission is required.
## 5. Ownership
We and our licensors retain all ownership and intellectual-property rights in
the Game. This includes its software, gameplay content, visual art, audio,
writing, characters, world, trade marks, and all authorised copies. All rights
not expressly granted in this Agreement are reserved.
## 6. Early Access and updates
The Game may be offered in Early Access or another pre-release state. If so,
you understand that it is unfinished and may contain defects; features,
balance, content, system requirements, and save compatibility may change during
development. The current advertised Early Access scope, rather than unannounced
or planned features, describes what is included in your purchase.
We may provide patches, updates, or other changes for reasonable purposes such
as improving the Game, adding content, maintaining compatibility, correcting
defects, or protecting security and fair play. Platform settings may install
updates automatically. We do not promise any particular future feature or
release date unless applicable law or an express written commitment requires
otherwise. Nothing in this section limits your mandatory rights when digital
content does not conform to the contract.
## 7. Online and platform features
The Game may interact with platform services such as player identity,
achievements, rankings, cloud storage, or other online features. Availability
may depend on third-party services and may be interrupted, changed, or
discontinued. We will not intentionally remove a material paid feature without
regard to applicable consumer law.
To protect fair rankings, we may reject or remove scores that are corrupted,
impossible, manipulated, submitted through an ineligible game mode, or
reasonably determined to result from cheating or automation. If account or
score sanctions are introduced, they will be applied proportionately and with
any process required by applicable law.
## 8. Saves, progression, and in-game items
Save files, rankings, progression, and in-game currencies or items form part of
the Game experience. Unless expressly sold for real money under separate terms,
they have no cash value, are not legal tender or property independent of the
Game, and may not be sold or transferred. They may be changed by gameplay,
updates, data corruption, or valid enforcement action. You should use available
backup or platform-cloud features where appropriate.
## 9. Privacy notice and local data
This section is the privacy notice for the current version of the Game. We do
not receive or remotely collect personal data through the current Game build.
The Game may read your Steam display name and Steam ID to identify ranking
records and may store them locally with Game save data. Run telemetry, saves,
settings, and progression data are also stored locally on your device. The
current Game does not transmit those files or records to us, and we cannot
access them unless you choose to send them to us, for example when requesting
support.
If you contact us by email, we will receive the address, message, and any files
or other information you voluntarily provide. We will use that information to
respond, investigate the issue, protect the Game or our rights, and comply with
law. We will retain it only for as long as reasonably necessary for those
purposes or a legal obligation.
If we later enable online rankings, remote telemetry, cloud services under our
control, or another remote data-collection feature, we will first publish an
updated privacy notice and provide any notice or choice required by law.
Steam and other third-party platforms process information under their own
privacy policies. We do not control their independent processing.
## 10. Third-party software and services
The Game includes or relies on software, content, and services supplied by
third parties. Applicable open-source licences and attribution notices are
provided with the Game or in its credits or notices. Those notices may grant
you additional rights for the relevant third-party component. Third-party
platforms and services are governed by their own terms.
## 11. Term and termination
This Agreement continues until terminated. You may terminate it at any time by
stopping use of the Game and uninstalling all copies under your control.
To the extent permitted by law, we may terminate your licence for a material
breach of this Agreement if the breach cannot be remedied or remains unremedied
after reasonable notice. We may act without prior notice where reasonably
necessary to address fraud, unlawful conduct, a serious security threat, or
deliberate interference with rankings or services. Termination does not affect
rights or liabilities that accrued before termination. Sections that by their
nature should continue after termination will survive, including Sections 3,
5, 9, 10, 12, 13, 14, 15, and 17.
## 12. Warranty disclaimer
Nothing in this Agreement excludes or limits a guarantee, warranty, remedy, or
other right that applicable law does not allow us to exclude or limit.
Subject to those mandatory rights, the Game is provided **“as is”** and **“as
available.”** To the maximum extent permitted by law, we disclaim implied
warranties of merchantability, fitness for a particular purpose,
non-infringement, uninterrupted availability, and error-free operation. We do
not warrant that the Game will be compatible with every device, configuration,
driver, modification, or third-party service.
## 13. Limitation of liability
Nothing in this Agreement excludes or limits liability where doing so would be
unlawful, including liability for fraud or fraudulent misrepresentation,
intentional misconduct or gross negligence, or death or personal injury caused
by negligence where applicable law prohibits its exclusion.
To the maximum extent permitted by law, we will not be liable for indirect,
incidental, special, consequential, or punitive loss, or for loss of profits,
business, opportunity, goodwill, or data, arising from the Game or this
Agreement. Where the law allows a monetary cap, our total aggregate liability
arising from the Game or this Agreement will not exceed the amount you paid for
the Game. These exclusions and limits apply only to the extent they are fair,
reasonable, and enforceable under applicable law.
## 14. Consumer rights and refunds
You may have statutory rights concerning digital content, including rights to
conformity, remedies, refunds, withdrawal, or cancellation. This Agreement does
not restrict those rights. Purchases and refund requests made through Steam or
another platform are also handled under that platform's refund process,
including the [Steam Refunds
policy](https://store.steampowered.com/steam_refunds/) where applicable,
without prejudice to any additional rights provided by law.
## 15. Governing law and disputes
This Agreement is governed by the laws of the **Republic of Korea**, without
regard to conflict-of-law rules. If you are a consumer, this choice does not
deprive you of mandatory protections provided by the law of your country of
residence.
Before filing a claim, you and we should make a reasonable attempt to resolve
the dispute by contacting each other. Any unresolved dispute may be brought in
a court that has jurisdiction under applicable law. This Agreement does not
require individual arbitration, waive participation in a class or collective
proceeding, or force a consumer to use a forum where such a requirement would
be unlawful.
## 16. Changes to this Agreement
We may update this Agreement for a valid reason, such as a change to the Game,
our services, or applicable law. Material changes will apply prospectively. We
will provide reasonable advance notice through the Game, its store page, or
another appropriate channel, except where an immediate change is reasonably
required for law or security. We will request consent where applicable law
requires it. The current effective date will appear at the top of the
Agreement.
## 17. General terms
If a court finds part of this Agreement unenforceable, that part will be
applied to the greatest extent permitted and the remainder will continue in
effect, unless doing so would materially change the bargain. Our failure to
enforce a provision is not a waiver. We may transfer this Agreement as part of
a genuine transfer of the Game or our business, subject to applicable law; you
may not transfer it except as the applicable platform or law permits.
This Agreement, together with the Privacy Policy and any terms expressly
incorporated here, is the entire agreement between you and us about the Game.
It does not replace the separate terms governing Steam or another platform.
