ONE store Review Guidelines


The ONE store Developer Center Verification Guidelines help developers remove and identify risks in advance to ensure a successful business. We will support developers to provide the best experience and satisfaction they seek by protecting users of ONE store products.

Basic Principles of ONE store Content Review

  • A “product” refers to an application provided through ONE store and includes content, physical products, services, etc.
  • We protect users, especially underage ones, from harmful content such as illegal, obscene, and violent information on the app market. Simultaneously, we strive to uphold the ethics and integrity of the app ecosystem by ensuring the developer's freedom of expression is maximized as much as possible.
  • We build a reliable app ecosystem by actively reflecting the interests and opinions of users, as well as the responsibility of developers, for the safety of the app market.
  • ONE store's review standards respect the relevant laws and social norms of the target country and aim for global values.
