Evoluta Terms of Service

1. Purpose

These Terms govern the use of Evoluta (the "Service"), a web-based mechanical component design calculation service operated by Evoluta (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 and completes the sign-up procedure. Once the user verifies their email, the Service becomes available immediately.
2. The Company may refuse registration or restrict use 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. To prevent fraudulent sign-ups and misuse of the Service, the Company may verify, after registration, the stated purpose of use and organisation. Where a ground under clause 2 is confirmed, the Company may restrict use or terminate the agreement under clause 13.

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.

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.

8A. Notice regarding bearing catalogue data

1. Bearing catalogue information in the Service (designations, boundary dimensions, load ratings and the like) is reference material compiled from published catalogue data. Unless expressly stated otherwise, it is not warranted, approved or endorsed by the manufacturer concerned, and the Company has no affiliation with any bearing manufacturer.
2. Catalogue information may differ from the current product because of manufacturer revisions and may change without notice.
3. Internal geometry used for stiffness, contact and life calculations (number, diameter and pitch diameter of rolling elements, contact angle and the like) is estimated from the boundary dimensions where the manufacturer has not published it. The Service marks on screen and in the report whether such a value is published or estimated.
4. Before final design or manufacture, users must confirm internal geometry and ratings with the manufacturer's official data or their own measurements. The Company does not warrant the accuracy, completeness or fitness for any purpose of catalogue information; liability for its use is governed by Articles 14 and 15.

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.
