The products and services we provide include, but are not limited to, existing developer services (Gravity Engine SDK/gravityengine) and other products and services that are periodically innovated and developed.

This Policy describes the purposes, methods, scope, and information security protection measures for collecting, using, storing, sharing, and transferring your personal information and that of your end users in the course of providing you with products and/or services on this Platform, as well as the rights and methods we provide to you for controlling such personal information, including access, correction, and deletion. To facilitate your reading and understanding, we have used simple and easy-to-understand language and defined key terms. Please refer to "Appendix 1: Definitions of Key Terms" in this Policy.

You acknowledge and confirm that you have read and fully understood all contents of this Policy upon registration. Please note that we specifically highlight personal sensitive information in bold italic text, and clauses that significantly affect your rights and interests or those of your end users in bold text. Before providing us with any personal sensitive information belonging to you and/or your end users, please carefully consider whether such provision is appropriate and agree that we may process your personal sensitive information and that of your end users for the purposes and in the manner described in this Policy. We will collect and use your personal sensitive information and that of your end users only upon obtaining your consent, to realize the relevant functions provided by this Platform to you. You are allowed to opt out of the collection and use of your personal sensitive information and that of your end users; however, refusing to provide such information will affect the ability of this Platform to provide you with related service functions.

Please read carefully and understand the detailed information regarding specific products in this Policy before using our products or services. We hope that when you use Gravity Engine products and/or services, you make informed decisions regarding the provision of your personal information and that of your end users. If you do not agree with this Policy, you should immediately stop using the products and/or services we provide, including the Gravity Engine platform, website, etc.

It is necessary to specifically note that when you use our products and services, we will process two main categories of personal information:
