Version-specific scope. These Terms of Use are valid only for Rucoy Calculator version 0.6.0 (build 10). They do not automatically apply to earlier versions, later versions, modified builds, forks, unofficial distributions, websites, or other products. Other versions may be governed by different terms.

1. Agreement to These Terms

These Terms of Use (“Terms”) govern use of Rucoy Calculator version 0.6.0 (“App”), developed by Apollo Daniel (“Developer,” “we,” “us,” or “our”).

By installing, accessing, or using this version of the App, you agree to these Terms and to the version-specific Privacy Policy.

If you do not agree, do not use the App and uninstall it.

Nothing in these Terms excludes or limits rights that cannot legally be excluded, including mandatory rights available under applicable consumer-protection and data-protection laws.

2. Contact

Questions about these Terms may be sent to:

• Email: developer.apollo.mail@gmail.com

When contacting the Developer, state that the matter concerns Rucoy Calculator version 0.6.0 (build 10).

3. Description of the App

Rucoy Calculator is an independent calculator and reference tool associated with gameplay concepts from Rucoy Online. Version 0.6.0 includes calculators and reference information involving matters such as:

• Levels and experience;
• Skills and statistics;
• Training and power training;
• Weapons and attack types;
• Monsters;
• Potions;
• Offline training;
• Grinding;
• Player-kill skull mechanics; and
• Other gameplay-related estimates and comparisons.

The App may also provide:

• Locally saved calculator templates;
• Language and interface settings;
• Update checks through Google Play;
• Advertisements through Google AdMob;
• Privacy choices through Google UMP;
• Optional donation links or Pix information; and
• Links to external communities, social networks, stores, and services.

4. Unofficial and Independent Status

Rucoy Calculator is an unofficial, independent, fan-made application.

The App is not affiliated with, controlled by, sponsored by, endorsed by, or officially approved by Rucoy Online or its respective owners, developers, publishers, or rights holders.

References to Rucoy Online, gameplay terminology, visual materials, names, icons, images, and other third-party material are used only to identify or describe the subject of the calculator. All third-party trademarks, copyrights, game assets, and other rights remain with their respective owners.

Use of the App does not grant the user any ownership of or license to Rucoy Online, its game, servers, accounts, trademarks, artwork, or other third-party property.

5. Eligibility and Minors

The App may be used by different age groups, but minors must use it only with the permission and supervision required by their local law and by a parent or legal guardian.

For advertising configuration, version 0.6.0 asks the user to choose one of three technical categories:

• Under 13;
• 13 to 17; or
• 18 or older.

These categories are used for advertising protections and are not a universal determination of legal adulthood or contractual capacity.

A parent or legal guardian should make or verify the selection for a child when required. Users must provide an accurate age category. Deliberately selecting an inaccurate age category to bypass advertising or privacy protections is prohibited.

Under-18 users receive non-personalized advertising through the App’s request configuration, and under-13 users receive child-directed treatment.

6. Limited License to Use the App

Subject to these Terms and applicable store rules, the Developer grants you a limited, non-exclusive, non-transferable, non-sublicensable license to install and use version 0.6.0 of the App for lawful personal use.

This license permits use of the distributed App only. It does not grant access to, ownership of, or any right to copy, modify, publish, distribute, sublicense, sell, reverse engineer, or create derivative works from the App’s source code, except to the extent that a right cannot lawfully be restricted.

No source-code or open-source license is granted by these Terms. If the Developer separately provides particular source code or other material together with an express written license, that separate license applies only to the material and recipient covered by it.

Third-party packages, fonts, icons, game-related materials, trademarks, images, and other dependencies may be governed by separate licenses or rights. These Terms do not grant rights in third-party material.

7. Acceptable Use

You agree to use the App lawfully and responsibly.

You must not use the App to:

• Violate applicable law, regulation, court order, or another person’s rights;
• Access, interfere with, attack, scrape, overload, or disrupt Rucoy Online, Google, payment providers, linked services, or another system;
• Automate gameplay, control a game client, evade game rules, or represent that the App provides official authorization to do so;
• Generate fake, automated, accidental, incentivized, or fraudulent advertising impressions or clicks;
• Manipulate advertising identifiers, consent signals, age settings, traffic, or requests for fraudulent purposes;
• Distribute malware, spyware, harmful code, or deceptive modified builds;
• Misrepresent an unofficial or modified build as an official release by the Developer;
• Use the App or its name to impersonate the Developer, Rucoy Online, or another person;
• Enter another person’s sensitive personal information into local template names or calculator fields without authorization; or
• Use external links or contact channels for harassment, spam, fraud, or abuse.

This section does not restrict any right expressly granted to you in a separate written license that accompanies specific material, provided you comply with that license, applicable law, third-party rights, store rules, and branding obligations.

8. Calculator Results and Informational Nature

The App provides estimates and calculations based on:

• User-entered values;
• Locally included formulas and datasets;
• Assumptions made during development; and
• Information available to the Developer when version 0.6.0 was prepared.

Results are provided for general informational and entertainment purposes. They are not official Rucoy Online results, guarantees, promises, or representations by the game’s operators.

The game may change without notice. Updates to game mechanics, balancing, experience tables, items, monsters, skills, formulas, server behavior, rounding rules, or other factors may make App results incomplete, outdated, or inaccurate.

You are responsible for checking important results and deciding whether to rely on them. The Developer is not responsible for lost game time, lost virtual items or currency, account penalties, missed opportunities, incorrect training plans, or other consequences arising from reliance on a calculation, except where liability cannot legally be excluded.

9. User Inputs and Local Templates

The App allows users to enter calculator values and create named templates stored locally on the device.

You retain any rights you have in original text that you enter. Version 0.6.0 does not provide a Developer-operated cloud synchronization service for templates and does not grant the Developer ownership of locally stored template content.

You are responsible for:

• The accuracy of your inputs;
• Avoiding sensitive or unlawful information in template names;
• Maintaining a backup of information you consider important;
• Protecting access to your device; and
• Deleting local data before transferring or disposing of the device.

Local data may be lost because of uninstallation, clearing App storage, operating-system action, device failure, corruption, App changes, or user error. The Developer does not guarantee recovery.

10. Advertising

Version 0.6.0 uses Google AdMob and Google UMP.

When applicable and permitted:

• A banner advertisement may be displayed;
• One interstitial advertisement may be attempted per App session when the user chooses to calculate again;
• Adult users may receive personalized ads only when the applicable Google consent signals permit them;
• Users under 18 receive non-personalized ads through the App’s configuration; and
• Ads may be blocked when Google does not indicate that an ad request is permitted.

Advertisements and advertised products are supplied by third parties. An advertisement is not a recommendation, warranty, or endorsement by the Developer.

You are solely responsible for evaluating any advertised product, service, offer, website, or application. Transactions with advertisers are between you and the relevant third party.

You must not click advertisements merely to support the Developer, create invalid traffic, test production ads, or manipulate advertising revenue. Click an ad only when you have genuine interest in it.

Advertising and privacy processing are further described in the version-specific Privacy Policy and Google’s policies.

11. Privacy and Age Settings

Use of the App is also governed by the Privacy Policy for version 0.6.0.

You agree to provide an accurate age-range selection. You may change the selected age range in App settings. Changing it causes version 0.6.0 to block stale ad requests, reset the prior Google UMP consent state, and run the privacy flow again.

Eligible users may be offered an in-App privacy-options button supplied through Google UMP. The availability and content of that form depend on Google’s systems, region, age category, consent status, and applicable law.

Refusing personalized-ad consent does not remove the core calculator functionality. Depending on Google’s eligibility decision, the App may show non-personalized ads or may not request ads.

12. Optional Donations

Donations are voluntary. A donation is not:

• A purchase of the App;
• A subscription;
• A payment required to access calculators;
• A purchase of Rucoy Online items, currency, or services;
• A guarantee of support, updates, features, priority, or influence; or
• An investment or ownership interest.

Version 0.6.0 may provide:

• A static Pix key or Pix QR code;
• Ko-fi;
• Patreon; and
• PayPal.

12.1 Pix donations

The Pix code is intended to open or be pasted into a compatible banking or payment application. You are responsible for checking the recipient, amount, and transaction details before confirming payment.

The App does not control your bank or payment provider and cannot cancel a completed Pix transfer.

12.2 Third-party donation providers

Ko-fi, Patreon, and PayPal are independent services governed by their own terms, fees, refund rules, account requirements, taxes, and privacy notices.

The Developer is not responsible for provider outages, account restrictions, conversion rates, bank charges, taxes, payment disputes, chargebacks, or unauthorized transactions caused outside the Developer’s control.

12.3 Refunds

Because donations are voluntary and normally do not purchase a digital feature, they are generally not refundable after completion unless:

• Applicable law requires a refund;
• The payment provider’s rules require one;
• The payment was unauthorized or duplicated and is properly established; or
• The Developer expressly agrees otherwise.

Contact the payment provider first when the matter concerns its account, processing, or transaction system.

13. External Links and Services

The App may open external destinations, including Google Play, Rucoy Online’s store listing, GitHub, WhatsApp, Discord, YouTube, Ko-fi, Patreon, and PayPal.

The Developer does not control and is not responsible for:

• Availability or security of external services;
• Their content, users, moderation, advertising, or transactions;
• Their collection or use of personal data;
• Account bans, suspensions, purchases, subscriptions, or messages;
• Malware, scams, misleading content, or third-party conduct; or
• Changes to their terms or policies.

A link is provided for convenience and does not necessarily mean endorsement.

You must review the external provider’s terms and privacy policy before using it.

14. Experimental and AI-Assisted Translations

Some language translations in version 0.6.0 may be experimental, machine-assisted, or AI-assisted.

Such translations may contain mistakes, unnatural wording, omissions, ambiguous terminology, or inaccurate descriptions. Users should not rely on an experimental translation when exact meaning is important.

The underlying formulas and interface behavior may be the same while translated labels differ. Reports of translation errors may be sent through the contact information in Section 2.

15. Updates and Compatibility

Version 0.6.0 may check Google Play for a newer App version and may display an update screen.

The Developer does not promise that:

• Updates will be released;
• Version 0.6.0 will remain compatible with future Android versions;
• The App will remain listed in a store;
• Every device will be supported;
• Third-party packages or services will remain available;
• Old calculations will remain accurate after game changes; or
• A later version will retain every feature, setting, template format, language, or advertising behavior.

A later version may have separate Terms and a separate Privacy Policy. Installing or using a later version may require acceptance of its own terms.

16. Availability, Maintenance, and Discontinuation

The App is provided without a guaranteed service level.

The Developer may, subject to applicable law:

• Correct, change, remove, or add features in later versions;
• Stop maintaining version 0.6.0;
• Stop distributing the App;
• Remove external links;
• Change donation methods;
• Replace or remove advertising integrations; or
• Publish security or compatibility updates.

Because version 0.6.0 has no Developer-operated user account, the Developer does not remotely terminate an individual account. You may terminate your use at any time by stopping use and uninstalling the App.

17. Intellectual Property

Except for third-party materials and any rights expressly granted under a separate written license accompanying specific material:

• The App’s original branding, layout, original text, original code, and original design elements are owned by or licensed to the Developer;
• The Developer’s name and branding may not be used to imply endorsement of a modified or unrelated product;
• Rucoy Online and its related names, marks, imagery, and game materials remain the property of their respective rights holders; and
• Third-party libraries, icons, fonts, and services remain subject to their own licenses and terms.

If you believe material in the App infringes your rights, contact developer.apollo.mail@gmail.com with identification of the work, the allegedly infringing material, your authority to act, and sufficient contact information.

18. No Game Account Access or Game Service

Version 0.6.0 does not require or request Rucoy Online account credentials and does not provide a game login, game client, bot, automation service, marketplace, or connection to a Rucoy Online account.

The App cannot:

• Protect a game account;
• Restore lost game items or currency;
• Reverse a game ban;
• Guarantee compliance with game rules;
• Change server data;
• Complete in-game transactions; or
• Provide official customer support for Rucoy Online.

Questions about the game or a game account must be directed to the game’s official channels.

19. Disclaimer of Warranties

To the maximum extent permitted by law, the App and its content are provided “as is” and “as available.”

The Developer does not make an absolute guarantee that the App will:

• Be error-free, uninterrupted, secure, or always available;
• Produce exact or current results;
• Work on every device;
• Preserve every template or setting;
• Display a particular advertisement;
• Remain compatible with Google, Android, Google Play, payment providers, or Rucoy Online;
• Be free of translation errors; or
• Meet every user’s individual purpose.

Nothing in this section limits a warranty or remedy that cannot legally be excluded.

20. Limitation of Liability

To the maximum extent permitted by applicable law, the Developer will not be liable for indirect, incidental, special, punitive, exemplary, or consequential loss arising from use of or inability to use the App, including loss involving:

• Game progress, virtual currency, items, time, or opportunities;
• Incorrect calculations or outdated game information;
• Lost local templates or settings;
• Device, software, network, or third-party-service failure;
• External advertisements, links, purchases, donations, or communications;
• Account actions taken by Rucoy Online or another third party; or
• Unauthorized access caused by circumstances outside the Developer’s reasonable control.

Where liability cannot be excluded, it is limited only to the extent permitted by law and subject to proof of actual loss and legal causation.

Nothing in these Terms excludes or limits liability for fraud, intentional misconduct, gross negligence where it cannot be limited, personal injury caused by legally attributable conduct, or mandatory consumer rights.

21. Responsibility for Third-Party Conduct

The Developer is not a party to agreements between the user and:

• Rucoy Online;
• Google;
• An advertiser;
• A bank or Pix participant;
• Ko-fi;
• Patreon;
• PayPal;
• GitHub;
• WhatsApp;
• Discord;
• YouTube; or
• Another linked service.

Disputes involving those providers may need to be addressed directly with them. This clause does not eliminate any responsibility the Developer has under mandatory law for the Developer’s own conduct.

22. Reporting Security Issues or Abuse

Security vulnerabilities, harmful modified builds, impersonation, or misuse of the Developer’s identity may be reported to:

developer.apollo.mail@gmail.com

Do not publicly disclose credentials, private keys, personal data, or an unpatched vulnerability before allowing a reasonable opportunity for responsible review.

The Developer does not offer a bounty or guarantee payment for reports unless a separate written program expressly says otherwise.

23. Changes to These Terms and Version Limitation

These Terms govern only version 0.6.0 (build 10).

They do not automatically govern:

• Version 0.5.0 or earlier;
• Version 0.6.1 or later;
• Development or debug builds;
• Modified APKs or bundles;
• Forks and third-party distributions;
• A web version;
• Another App by the Developer; or
• External services opened from the App.

A later release may publish different Terms. Those later Terms do not retroactively change these version 0.6.0 Terms unless required by law or expressly agreed.

Third-party services may change their own terms while the user remains on version 0.6.0. Their current terms govern use of their services.

24. Governing Law and Disputes

These Terms are governed by the laws of the Federative Republic of Brazil, without excluding mandatory protections that apply in the user’s place of residence.

Before filing a dispute, the user and Developer should attempt in good faith to resolve the matter through the contact email in Section 2.

Any court venue will be determined according to applicable law. Nothing in these Terms requires a consumer to waive a legally protected right to bring a claim in the consumer’s competent local forum.

25. Severability

If a provision of these Terms is held invalid or unenforceable, it will be interpreted or limited to the minimum extent necessary, and the remaining provisions will continue in effect where legally possible.

26. No Waiver

A failure to enforce a provision does not waive the right to enforce it later.

27. Assignment and Project Transfer

Any rights granted under a separate written license accompanying specific material remain governed by that separate license.

The Developer may transfer responsibility for maintaining or distributing the App, together with relevant legal rights and obligations, subject to applicable law. Because version 0.6.0 does not maintain a user-account database, there is ordinarily no App account to transfer.

28. Entire Agreement

For version 0.6.0, these Terms, the version-specific Privacy Policy, any separate written license expressly provided with specific material, and any mandatory third-party terms form the applicable agreement concerning their respective subjects.

A separate written license controls only the material and rights it expressly covers. Third-party terms control use of third-party services. Mandatory law controls where it cannot be changed by agreement.

29. Contact
