These Terms constitute the Supplemental Terms, etc. set forth in Article 1 of the Nulab Terms of Use (the “Basic Terms”) and form a part of the Basic Terms.

Matters not set forth in these Terms shall be governed by the Basic Terms, the Data Processing Addendum (DPA) separately established by the Company, and the Privacy Policy. In the event of any inconsistency or conflict between these Terms and the Basic Terms, the DPA, or the Privacy Policy, the provisions of these Terms shall prevail unless otherwise provided.
