This Acceptable Use Policy (this “Policy”) describes prohibited uses of the Services offered by Circle Internet Services, Inc., dba CircleCI (“CircleCI” or “our”). This Policy supplements, and is incorporated into, CircleCI’s applicable online Software Agreement (currently published at https://circleci.com/legal/terms-of-service/ or https://circleci.com/legal/enterprise-license-agreement/, as applicable) or the negotiated SaaS Agreement or Software License Agreement or other documents entered between the Parties (the applicable agreement, “Agreement”). In the event of any conflict or inconsistency among the following documents, and, except as otherwise expressly set forth in an Order and/or signed agreement between the parties, the order of precedence shall be (i) this Policy, (ii) the Agreement, and (iii) the Documentation.

If you violate this Policy, CircleCI may deny access, suspend, or terminate your use of the Services (or any part thereof).

CircleCI may modify this Policy at any time by posting a revised version on the Site. By using the Services, you agree to the latest version of this Policy.
