Terms of service

Article 1 (Purpose; Scope)

  1. These Terms govern the conditions for using the Service. In order to use the Service, the user (as defined in Article 2) must agree to these Terms and complete registration procedures designated by the Company.

  2. With respect to the Service, any application forms, order forms, memoranda, individual agreements, service level agreements (“SLA”), operational guides, privacy policies, and other documents entered into between the Company and the Customer (collectively, “Individual Agreements”) constitute a part of these Terms. If any Individual Agreement contains provisions that differ from these Terms, the Individual Agreement shall prevail.

The amended Terms shall become effective upon posting or notification by the Company using a method designated by the Company (including posting within the Service and/or notice by email). If a user continues to use the Service after such change becomes effective, the user shall be deemed to have agreed to the amended Terms.

  4. These Terms are intended primarily for use by business entities, including corporations and sole proprietors. If these Terms are applied to consumers (individuals acting for personal use), mandatory consumer protection laws may prevail to the extent applicable.

  5. Notices, declarations of intent, and consents under these Terms may be validly made by electronic means (including via the web, email, and clicks within an admin console).

Article 2 (Definitions)

For purposes of these Terms, the following terms have the meanings set forth below:

  1. Customer: A corporation or individual who agrees to these Terms and enters into a contract with the Company for use of the Service (the “Subscription Agreement”).

  2. Account Administrator: The Customer itself, or an individual who represents or acts on behalf of the Customer and is authorized to perform contractual and payment-related procedures for the Service, including: (i) registering for the Service, (ii) viewing subscription details and payment history, (iii) changing plans, (iv) changing payment methods, (v) changing the Account Administrator, (vi) applying to terminate use of the Service, and other subscription/payment procedures. The Account Administrator shall have legal authority to perform such acts (e.g., representative authority, power of attorney, or internal delegation).

  1. Plan Categories: The Service includes Free Plans and Paid Plans. Users may select and register for a plan using a method designated by the Company.

  2. Free Plan: Under the Free Plan, Users may use only some of the functions available in the Paid Plan, free of charge. The Free Plan may be subject to limitations such as available features, data capacity, API call limits, concurrent connections, support levels, retention periods, export functions, and similar restrictions. The Company may change such limitations within a reasonable scope.

  4. Upgrade from Free Plan to Paid Plan: A Customer on a Free Plan may migrate to a Paid Plan via the Admin Console or designated application procedures. The migration becomes effective upon completion of the application procedure or the Company’s acceptance, and fees will accrue thereafter in accordance with the Price List. Data and settings in the Free Plan may be carried over to the Paid Plan in accordance with the Company’s migration conditions; however, certain features or histories may not be eligible for migration.

  5. Plan Changes (Upgrade/Downgrade): The Customer may change between Paid Plans using the method designated by the Company. An upgrade becomes effective on the start date specified by the Company after the application is completed.
