Terms of Service

In the event KLB provides a new Service in the future, KLB may establish additional terms and conditions for that new Service. Those additional terms and conditions shall become part of these Terms (collectively, “the Terms, etc.”). If there is a conflict between these Terms and the additional terms, the additional terms shall take precedence.

Before using the Services, you (“the customer”) must clearly understand and agree to all of the Terms, etc.

  1. Conclusion of Terms of Use
    To use the Services, the customer must (a) create an account on the official website or (b) install the application on an electronic terminal.

  4. Changes to the Terms
    KLB may change these Terms or the guidelines, etc., at any time without prior customer approval. Unless otherwise specified, changes take effect at the time designated by KLB after they are published through the Services or official website. If no effective time is stated, the changes take effect immediately upon publication.

  5. Acceptance of Changes
    If the customer continues to use any part of the Services, including making any required payments for paid features, after changes to these Terms are posted, the customer is deemed to have accepted those changes.
