Article 3 (Display, Explanation, and Amendment of the Terms)

① Calcat shall make the contents of these Terms available to users via a separate linked page within the website service screen so that users can easily understand them.

② Before users agree to these Terms, Calcat shall provide explanations or linked screens on a separate page so that users can understand important content of the Terms, such as withdrawal of subscription, delivery responsibilities, and refund conditions.

③ Calcat may amend these Terms within the scope that does not violate applicable laws. When these Terms are amended, Calcat shall announce the effective date and reason for the amendment through service notices from 7 days before the effective date until the day before the effective date. However, where the change is unfavorable to users, Calcat shall announce it at least 30 days before the effective date. In such case, Calcat shall clearly compare the pre- and post-amendment content so that users can easily understand it, and where individual notice is required for unfavorable changes, Calcat shall notify each member individually by email or other means.

④ Where Calcat has clearly notified, in the announcement above, that failure to express refusal within 7 days from the announcement date until the effective date of the amended Terms will be deemed consent to the amendment, and a member does not expressly refuse during that period, the member shall be deemed to have agreed to the amended Terms.

⑤ When Calcat amends these Terms, the amended Terms apply only on or after the effective date, and if a member does not agree to the amended Terms, the company cannot apply the amended Terms to that member, and the member may terminate the Service agreement. In such case, if there are special circumstances under which the company can no longer apply the existing Terms to a member who has not agreed to the amended Terms, the company may terminate the Service agreement with that member.

However, Calcat shall give individual notice with respect to matters that have a material impact on a member's own individual transactions.

Article 5 (Formation of the Service Agreement)

Where the User has been subject to a use restriction or has previously lost member status due to violation of these Terms or detailed guidelines; provided, however, that this does not apply to a person who has obtained Calcat's approval for re-registration after 3 years have passed since the use restriction or loss of member status.
