Flip, Inc. ("we") sets out below the privacy policy (this "Policy") that governs how we handle user information, including personal information, in the smartphone application "melamela" (the "App") that we provide.

Please read this Policy carefully before using the App.

Article 1 (Operator)

The App is provided by Flip, Inc. (Representative: Keisuke Iizuka; Address: 2-276-1 Kosugicho, Nakahara-ku, Kawasaki-shi, Kanagawa 211-0063, Japan).

Article 2 (Definitions)

  1. "Personal information" means personal information as defined in the Act on the Protection of Personal Information of Japan (the "APPI"): information about a living individual by which that individual can be identified, including information that can readily be cross-referenced with other information to identify an individual.
  2. "User information" means information that we collect under this Policy, including personal information, information that identifies a user, activity history within the App, content a user enters into the App, and other information generated or accumulated in connection with a user or a user's device.
  3. "Generative AI" means artificial intelligence technology that automatically produces text or other content based on user input and other data.

Article 3 (User information we collect and how we collect it)

We collect the following user information in the App.

(1) Information received from another service when you allow us to link to it

Using the App requires signing in with an Apple account (Sign in with Apple) or a Google account. If you allow the link, we collect the following from that external service, within the scope you consented to at the time.

(2) Information you provide to us

(3) Information we collect as you use the App

(4) Information we collect with your specific consent

Article 4 (Purposes of use)

We use user information for the following purposes.

  1. To register you, authenticate you, record your settings, and otherwise provide, maintain, protect and improve the App
  2. To use generative AI to produce events, posts, replies, direct messages, character and world profiles and the like, and to show them to you
  3. To show characters and worlds you have chosen to publish to other users
  4. To provide paid services and manage subscription status
  5. To issue and apply invitation codes and to grant invitation rewards
  6. To measure traffic and behaviour, improve the quality of the App and develop new features
  7. To deliver and display ads and measure their performance
  8. To send push notifications
  9. To send you information about the App and to answer your enquiries
  10. To prevent and respond to fraudulent acquisition of invitation rewards, creation of duplicate accounts, posting of inappropriate content and other breaches of our terms and policies (the "Terms")
  11. To notify you of changes to the Terms
  12. For purposes incidental to those above

Article 5 (Use of generative AI)

  1. The App uses generative AI provided by external companies to produce content. To produce it, what you enter, your play records, character and world information and other user information needed for generation are sent to the companies listed in Article 7.
  2. We record what is sent to the generative AI and what it produces, in order to check quality, investigate defects and prevent misuse.
  3. Content produced by generative AI is fiction, and we do not warrant that it is accurate, complete or useful. Even where the name of a real person or organisation appears, it does not represent anything that person or organisation actually said, did or believes.
  4. Please do not enter into the App the name, address, telephone number or other information that identifies you or a third party, or sensitive information such as race, creed or medical history. If you do, we will treat you as having consented to that information being sent to the generative AI and recorded, within the scope of this Article.

Article 6 (Published content)

  1. Characters and worlds you choose to publish are shown to other users, including their name, username, profile text, description, tags and images.
  2. If another user adds a published character or world to their play, the content as it stood at that moment is saved as part of that user's play records. Even if you unpublish it or delete your account, the content held in that other user's play records may not be deleted.
  3. Your own play records (posts, replies, direct messages and so on) are not shown to other users.

Article 7 (External services and transmission to them)

  1. The App uses the external services listed below to provide its features, and user information is transmitted to each company to the extent necessary to achieve the purposes of use. Each company handles that information according to its own privacy policy.
