We ask developers to understand and comply with the content of these guidelines along with various terms of use such as the mixi Platform terms and conditions. If we determine a developer doesn't comply with our guidelines, we may remove access to a part or all of the mixi Platform.

What is a mixi page app

The 'mixi page app' (subsequently referred to as 'mixi page app' or ' page app') is an application that adds features to a mixi page that you can install in a provided area of the mixi page. The mixi Connect guidelines apply to the use of the mixi Graph API. If mixi Connect guidelines and other various terms of use conflict with this guideline, this guideline takes priority. (We stopped accepting mixi page app new registrations.)

mixi page apps support the following and are limited to those available in a WEB browser.

  • PC version
  • Smartphone version
  • Mobile version

The developers who can develop mixi page apps are as follows.

  • A registered partner company who is authorized in a manner specified by mixi
  • A registered partner individual who is authorized in a manner specified by mixi
  • Others authorized by mixi

The basic information provision

The developer must disclose page app related information that users (the administrator of the mixi page installing the page app and the users who will view and use it. Hereinafter the same) should be aware of as much as possible in order for users to use the apps securely, and strive to avoid any possible misunderstandings with users.

  1. Publishing a Developer Information
    Please publish accurate developer information such as company name to the mixi page's administrator (subsequently referred to as 'page admin').
    Do not publish false or misleading information about the developer. Please do not misrepresent the nature of the developer's relationship with mixi.
  2. Description of the mixi page app
    • Description of the mixi page app
      Please write a description such as the page app functions and the service for pages admin to understand correctly when installing the page apps.
      The app needs to have a description of its usage to assist page administrator when adding the app.
      If an external site or an external app's data (subsequently referred to as 'external site, etc.') is provided to the mixi page by adding a page app, you need to clearly describe how the data will be used and the source of the data.
      Likewise, please clearly describe how the data will be used and the destination of the data if mixi page information is used on the external site, etc.
    • Description of the page app and externally managed applications
      Please make users understand usage after page app installation. Please provide access to help, etc. in the page app as necessary.
      Externally managed applications are required to have descriptions as well. In that case, the description of usage can be in the externally managed application instead of in the page app.

About project content

For 'published page apps', we ask you to provide value to users along the following concepts and the project contents.

  • Do not make users confused with the mixi service
    You must not provide a page app name, description, message, or feature that suggests the app is an official mixi application or mixi is providing or supporting the page app. Especially, a page app name starting with mixi is prohibited. You can't provide a feature that has no relation with mixi where a mixi feature exists with a similar name.
  • Do not damage the health of the social graph

You must not lead users to believe they are sharing only to friends, but the post is in a view that any user can view.
