REGNA terms of service

Effective: 15 June 2026 Last revised: 18 August 2026

Article 1 (Purpose)

These terms set out the basic matters between REGNA (the “Company”) and users in relation to use of the REGNA service (regna.tailgatelab.com and related services, the “Service”): rights, obligations and responsibilities, conditions of use and procedures.

Article 2 (Definitions)

  1. “Service” means everything the Company provides in support of medical device regulatory work (RA/QA): the AI assistant, the community forum, the regulatory newsroom, technical file drafting tools, test report review and the like.
  2. “User” means a member who has entered into a use agreement with the Company under these terms and uses the Service.
  3. “AI answer” means a response generated automatically by the Service using artificial intelligence in reply to a user's question.
  4. “Post” means any question, answer, comment, attachment or other information a user publishes or registers on the Service.
  5. “Credit” means the unit deducted when a feature of the Service is used.
  6. “Expert-verified answer” means a community answer marked (with a verification badge or similar) through a verifier or procedure designated by the Company. Its meaning follows Article 8 and the separate AI notice.

Article 3 (Publication and amendment of these terms)

  1. The Company publishes these terms on the Service where users can readily see them.
  2. The Company may amend these terms within the limits of applicable law, including the Act on the Regulation of Terms and Conditions and the Act on Consumer Protection in Electronic Commerce.
  3. Where the Company amends these terms it gives notice, stating the effective date and the reason, from 7 days before that date — or from 30 days before, where the change is unfavourable to users or material.
  4. A user who does not object before the effective date is deemed to have agreed to the amendment. A user who does not agree may terminate the use agreement.

Article 4 (Formation of the agreement, and accounts)

  1. The agreement is formed when a user agrees to these terms, applies to join after email and one-time-password verification, and the Company accepts the application.
  2. For security the Company may require additional authentication (MFA) when the Service is accessed from a new device.
  3. A user may verify a company email address (optional) to receive additional benefits such as credit rewards. In that case the rule is one account per company.
  4. A user may not transfer or lend account details or authentication methods to a third party, and is responsible for managing the account.

Article 5 (Provision, change and suspension of the Service)

  1. The Company provides the following.
    • AI assistant (regulatory Q&A, review of attached files and the like)
    • Community forum (questions and answers, adoption, voting, file upload and the like)
    • Regulatory newsroom
    • Technical file drafting tools (case creation, document upload and automatic classification, section drafts, STED assessment, HWP/DOCX export and the like)
    • Test report review
  2. The Company may change or suspend all or part of the Service as its content or operational and technical needs require. It gives notice beforehand by reasonable means, except where the matter is urgent, in which case notice may follow.
  3. The Service is currently provided in beta. Beta features are experimental. Their completeness, accuracy and continuity are not guaranteed and they may be changed or withdrawn without prior notice.

Article 6 (Nature of AI answers and other information, and the limits of disclaimer)

  1. AI answers provided by the Service are for information, and by the nature of the technology may contain errors, inaccuracies, omissions or statements that are untrue (hallucinations).
  2. AI answers, expert-verified answers, community answers and newsroom content are all reference information. The Company does not warrant their accuracy, completeness or currency. None of it is legal advice, regulatory consulting, a filing service or comparable professional advice.
  3. Before any decision that matters — an approval, a regulatory response, a product launch — you must check the official original from the competent authority and obtain review by a qualified professional. Responsibility for the decision and its consequences rests with the user.
  4. An “expert verified” mark indicates only that the answer went through a verification procedure. It does not mean the Company warrants the accuracy of its content or accepts responsibility for the outcome.

Article 7 (User obligations)

  1. A user must not:
    • infringe the rights of others (intellectual property such as copyright, reputation and the like), or upload or publish a third party's trade secrets or personal data without authority;
    • upload confidential information of the Company or a third party without authority;
    • create multiple accounts, obtain or use credits improperly, or otherwise abuse the Service;
    • carry out automated collection (crawling or scraping), reverse engineering, extraction of source code, or cause abnormal load;
    • act in breach of law or these terms.
  2. The user is responsible for the lawfulness of material uploaded to the Service (attachments and the like), for holding the necessary rights, and for non-infringement of third-party rights. Take particular care with material containing trade secrets, confidential information or a third party's personal data.
  3. Where a user breaches this Article and causes loss to the Company or a third party, the user is liable to compensate that loss.

Article 8 (Rights in posts, and licence to use them)

  1. Copyright in a post belongs to the user who wrote it.
  2. By registering a post, the user grants the Company a non-exclusive, royalty-free licence to use it within the scope of operating, providing, improving and promoting the Service. That licence includes:
    • display and storage within the Service;
    • indexing by search engines (limited to the scope the Company sets, such as posts the Company has marked as verified);
    • reuse in AI assistant answers (archive matching and re-citation of questions and answers the user published on the forum);
    • excerpts in materials introducing or promoting the Service.
  3. Where a user publishes an AI assistant answer on the forum, that question and answer become public content and the user agrees that the licence in paragraph 2 applies (community display, search engine indexing limited to verified posts, reuse in assistant answers and the like).
  4. The Company may delete, hide or restrict display of the following posts without prior notice, and moderation actions are retained in an audit log.
    • posts that infringe the rights of others or contain confidential information or personal data;
    • posts in breach of law or these terms.
  5. The Company's licence may continue for a reasonable period after a user deletes a post or the agreement ends, within the scope already reflected or archived in the Service and within the scope of backups and legal retention obligations.

Article 9 (Credits and paid services)

  1. The Service is offered as a free plan (Basic) and a paid plan (Advanced). The features, price, period and payment methods of each plan appear on the pricing page (/pricing), and prices shown include value-added tax.
  2. A “credit” is the unit of feature use. Credits renew monthly according to the plan, unused credits do not carry over to the next period, and different features consume different amounts. Credits are a usage allowance and have no cash value in themselves.
  3. A paid plan is a one-month pass paid by credit card and does not renew automatically. The plan activates as soon as payment completes.
  4. Withdrawal, termination and refunds for paid services follow the REGNA payment, withdrawal and refund policy (/legal/refund), which forms part of these terms. In summary:
    • withdrawal is possible within 7 days of the later of the payment date and the start date, with a full refund where no paid feature has been used;
    • on termination after using paid features, the proportion of credits used is deducted and the remaining days refunded pro rata (within 7 days of the start date); after 7 days the current month is not refunded;
    • where the Service is unavailable for 24 hours or more without interruption through the Company's fault, the fee for that period is refunded or the period extended;
    • refunds are made to the original payment method, and the process begins within 3 business days of the reason being confirmed.
  5. The Company gives at least 30 days' notice of a price change, in the Service or by email.

Article 9-2 (Mail-order seller and business details)

The Company's business details are as follows, shown identically at the foot of the Service's first screen, on the pricing page and in the refund policy.

Article 10 (Company obligations and limitation of liability)

  1. The Company endeavours to provide the Service reliably, in accordance with applicable law and these terms.
  2. The Company is not liable for loss arising from causes for which it is not responsible, including force majeure, causes attributable to the user, and failures of third parties (external AI model providers, telecommunications carriers, hosting providers and the like).
  3. Under Article 6 the Company does not warrant the accuracy of AI answers, community answers or other information, and bears liability for decisions a user makes in reliance on such information only within the limit in paragraph 4.
  4. Except for loss caused by the Company's wilful misconduct or gross negligence, the Company's total liability to a user in connection with use of the Service is limited to the total fees that user actually paid the Company in the three months immediately before the loss arose. (For services provided free of charge, no liability may arise absent wilful misconduct or gross negligence.)
  5. Nothing in this Article excludes or limits liability that cannot be limited under applicable law, including liability for wilful misconduct or gross negligence and for loss of life or personal injury.

Article 11 (Termination and restriction of use)

  1. A user may terminate the agreement (withdraw membership) at any time through the procedure in the Service.
  2. Where a user breaches these terms or the law, the Company may restrict use of the Service or terminate the agreement, on prior notice (or notice afterwards where the matter is urgent).
  3. On termination, the handling of a user's personal data follows the privacy policy and applicable law.

Article 12 (Governing law and jurisdiction)

  1. The laws of the Republic of Korea govern these terms and use of the Service.
  2. Jurisdiction over litigation arising between the Company and a user lies with the competent court under the Civil Procedure Act.
