+
+Please read the "User Improvement Plan" carefully, if you don't want to join this plan, just click the quit button in the bottom. This won't block you to use any features about the product.
+
+Under the plan, we're going to collect the information including:
+
+* System Information: it includes version of KubeVela and Kubernetes, IP address, timezone, region, etcd.
+* Operate Behavior Information: it includes which addon installed, the installation process, error info, cluster numbers, application numbers and types, etc.
+
+We promise the data collected can only be used to improve the product user experience and help up to make feature design and decisions.
+
+We're possible to modify this plan as the product growth, but we will update the plan and notify users about the updates. If you choose to use our service, that means you have agreed our plan and the modification.
