Voluta Terms of Service

Version 1.0 · Effective 2026-09-16 · Privacy Policy · 한국어

These Terms are a translation provided for convenience. The Korean version is the governing text; in case of any discrepancy, the Korean version prevails.

1. Purpose

These Terms govern the use of Voluta (the "Service"), a web-based mechanical component design calculation service operated by [Company name] (the "Company"), and set out the rights, obligations and responsibilities of the Company and the user.

2. Definitions

  1. Service — the design calculation tools for gears, shafts, bearings, bolted joints and related mechanical components that the Company provides over the web.
  2. User — a person who agrees to these Terms and uses the Service.
  3. Calculation Results — all output produced by the Service from the user's inputs, including values, pass/fail assessments, charts and calculation reports.
  4. Paid Service — plans and additional features the Company provides for a fee.

3. Changes to these Terms

  1. The Company posts these Terms so that they can be reviewed from the Service.
  2. The Company may amend these Terms within the limits of applicable law.
  3. Amendments are announced at least 7 days before the effective date, stating the effective date and the reason. For changes that are unfavourable to users or material, the notice period is at least 30 days and the Company also notifies users individually in the Service or by email.
  4. Continuing to use the Service after the effective date constitutes acceptance. A user who does not accept may terminate the agreement.

4. Formation of the agreement

  1. The agreement is formed when the user accepts these Terms, applies for an account, and the Company approves the application.
  2. The Company may withhold or refuse approval where the applicant uses another person's identity or submits false information; where the application is likely to impair the Service or other users; where the evident purpose is to develop a competing product or service; or where there is insufficient capacity or a technical obstacle.
  3. The Company may verify the stated purpose of use and organisation as part of the approval process.

5. Accounts

  1. An account is personal to one user and may not be shared, lent, transferred or pledged.
  2. The Company may limit each account to one concurrent session.
  3. The user must notify the Company immediately upon becoming aware of any compromise of account credentials.
  4. The Company is not liable for loss arising from the user's failure to safeguard credentials, except where the Company is at fault.

6. Provision of the Service

  1. The Company aims to provide the Service 24 hours a day, all year round.
  2. The Company may suspend the Service in whole or in part for maintenance or improvement, with prior notice where practicable and with notice afterwards in urgent cases.
  3. The Company may change the composition of the Service and add or discontinue individual tools. Changes to a Paid Service that are unfavourable to users are notified under clause 3.3.

7. Nature of Calculation Results and user responsibility

Please read this clause carefully. It is central to how the Service may be used.

  1. Calculation Results are reference material to support engineering judgement. They do not certify, approve or warrant the suitability or safety of a design.
  2. Calculations are performed on the values and conditions the user supplies. The accuracy and appropriateness of inputs, units and boundary conditions are the user's responsibility.
  3. Calculations are valid only within the scope, assumptions and limitations of the standard stated for each tool. The Service displays those assumptions and limits on screen and in the calculation report, and the user is responsible for reviewing them.
  4. Calculation Results do not replace prototype testing, independent analysis or field validation. The user must carry out verification in accordance with applicable law and industry practice before finalising a design, manufacturing or putting a product into service.
  5. For applications that may affect human life, cause serious harm or damage the environment — including aerospace, medical and nuclear applications — the user must perform independent verification and third-party review. The Company does not warrant fitness for such applications.
  6. The final design decision, and responsibility for its consequences, rest with the user.

8. Notice regarding technical standards

  1. The Service is a software implementation of calculation procedures defined in published technical standards such as ISO, DIN, AGMA and VDI.
  2. The Company does not supply the text of any standard. Users who need the text must obtain it lawfully from the publishing body.
  3. The Service is not certified, approved or endorsed by any standards organisation and has no affiliation with any such organisation. Standard designations are cited to identify the source of the implemented procedure.
  4. Results may differ because of revisions to a standard, differences between editions, or errors and internal inconsistencies within a standard itself. The Company states the basis and edition used in the calculation report but does not warrant exact agreement with any particular edition.

9. User obligations

The user must not:

  • impersonate another person or register false information;
  • reverse engineer, decompile or attempt to extract source code or algorithms from the Service;
  • place an excessive load on the Service or harvest data in bulk by automated means;
  • share or lend an account, or resell or redistribute the Service;
  • use the Service to develop a competing product or service;
  • infringe the intellectual property rights of the Company or any third party; or
  • act in breach of applicable law or these Terms.

10. Intellectual property and user data

  1. Intellectual property rights in the Service, including its software, interface and documentation, belong to the Company.
  2. Design data entered by the user, and the Calculation Results and reports derived from it, belong to the user. The Company does not use them beyond what is necessary to provide the Service.
  3. The Company may use statistics that cannot identify any individual or organisation to improve the Service. Even then, the Company does not disclose a user's design data to third parties.
  4. Users may freely use and distribute calculation reports produced by the Service for their own business purposes.

11. Paid Services and payment

  1. Fees, billing cycles and the scope of each plan are shown in the Service.
  2. A Paid Service becomes available once payment is confirmed.
  3. Subscriptions renew automatically each billing cycle until cancelled. A user may cancel at any time before the next billing date.
  4. The Company may change fees with notice under clause 3.3. Periods already paid for remain at the previous rate.

12. Withdrawal and refunds

  1. Users may withdraw from a purchase within 7 days of receiving the contract documentation, in accordance with the Korean Act on Consumer Protection in Electronic Commerce.
  2. Withdrawal may be restricted where the user has already used the Paid Service. Where that applies, the Company states it clearly at the payment screen and offers a trial opportunity.
  3. Where the Service is unavailable due to the Company's fault, the Company refunds the corresponding amount or extends the term.
  4. Refunds are normally made through the original payment method within the period required by law.
  5. Consumers resident in the European Union or the United Kingdom retain any statutory withdrawal or cancellation rights available to them under local law, which are not limited by this clause.

13. Termination

  1. The user may terminate at any time through the Service or by contacting the Company.
  2. The Company may restrict use or terminate the agreement after notice where the user breaches clause 9, or immediately with notice afterwards in urgent cases.
  3. On termination the Company handles personal data as set out in the Privacy Policy.

14. Disclaimer of warranties

  1. The Company does not warrant that the Service will be uninterrupted or free from error.
  2. The Company does not warrant that Calculation Results are fit for the user's particular purpose.
  3. The Company exercises due care in the accuracy of the Service, but this does not replace the user's verification obligations under clause 7.

15. Limitation of liability

  1. The Company is not liable for loss caused by force majeure, including natural disasters, power failures and network outages.
  2. The Company is not liable for loss arising from the user's input errors, use outside the scope of the applicable standard, or failure to perform the verification required by clause 7.
  3. Where the Company is liable, its aggregate liability shall not exceed the total fees paid by the user to the Company in the twelve months preceding the event giving rise to the claim. Where the Service was used free of charge, no liability arises.
  4. The Company is not liable for lost profits, business interruption, loss of data, or indirect, special or consequential loss.
  5. Clauses 15.3 and 15.4 do not apply to loss caused by the Company's wilful misconduct or gross negligence, to liability for death or personal injury, or where applicable law does not permit such limitation. Nothing in these Terms limits the statutory rights of consumers under mandatory law in their country of residence.

16. Governing law and disputes

  1. The Company and the user shall attempt to resolve disputes in good faith.
  2. These Terms are governed by the laws of the Republic of Korea.
  3. Disputes shall be brought before the court having jurisdiction under the Korean Civil Procedure Act. Consumers may also bring proceedings in the courts of their country of residence where mandatory local law so provides.
