2.4 Usage Data. ClickHouse collects tracking and operational data related to Customer’s use of the ClickHouse Security Cloud Component, including service metrics, metadata, and feature usage information (“Usage Data”). For the avoidance of doubt, Usage Data does not contain Content, and will not be shared with third parties except (a) to ClickHouse Affiliates, contractors, or service providers in accordance with Section 6 (Confidential Information) of this Agreement, or (b) in a form that omits Customer Confidential Information and does not identify Customer or an individual. ClickHouse owns all right, title and interest in and to Usage Data, which it reproduces, uses, modifies and adapts to provide, maintain, protect, improve, support, and bill for ClickHouse products and services.
