Last updated: September 1, 2026

1. Introduction

This Privacy Policy sets out how Hironari Takahashi ("we," "us," or "our") handles user information in the Listory iOS application (the "App") that we provide. By using the App, you are deemed to have agreed to this Policy.

5. Advertising

The App displays advertisements served by Google AdMob. Advertisements are displayed when you use the free version and are not displayed while you are subscribed to the paid Listory+ plan.

The App does not track users across other companies' apps or websites for advertising purposes. Advertising is configured to always be delivered as non-personalized advertising. Therefore, the App does not request permission under App Tracking Transparency.

6. Push Notifications

We store your device's push notification token to send notifications about follows, reactions, and similar activity. You can disable notifications individually in iOS Settings or in the App's settings.

7. User Posts and Visibility

Posts, comments, live event records, and similar content are displayed to other users according to the visibility setting you choose. A post set to "Everyone" can be viewed by anyone who uses the App. Please do not include information that infringes the rights of others or information that you do not want used to identify you.

8. Reporting, Blocking, and Moderation

The App includes features for reporting posts, comments, live event records, and users, as well as a feature for blocking users. We review reported content and, if we determine that it violates the Terms, may hide or delete the content or suspend the account. We retain report details and records of our response to prevent recurrence and conduct investigations.

9. Retention and Deletion

10. Age

The App is not intended for use by anyone under 13 years of age. If you are under 13, please do not use the App. If we learn that we have collected information from a person under 13, we will promptly delete it.

11. Security Measures

Communications are encrypted using HTTPS, and access to servers and databases is limited to what is necessary. However, we cannot guarantee absolute security for communications and storage over the internet.

12. Trademarks and Third-Party Content

Apple, the Apple logo, Apple Music, and App Store are trademarks of Apple Inc. Other company names, service names, and logos mentioned are trademarks or registered trademarks of their respective owners. The song information, artwork, and stickers displayed by the App are obtained from the services that provide them.

13. Changes to This Policy

We may revise this Policy in response to changes in laws or the addition of features. If we make material changes, we will provide notice in the App or on this page.
