Privacy policy

Clear handling of app data

This policy applies to apps published by Ichiro Ishii. Product-specific behavior and platform availability are identified in each app's public configuration.

Last updated September 16, 2026

Data stored on your device

Most app preferences, progress, and user-created content are stored locally on the device. Removing an app normally removes its local data, subject to the operating system's backup and restore behavior.

Network features and remote configuration

Apps may request public configuration files from the studio's listed hosting domains to check version requirements, service links, and feature settings. Hosting providers may process standard request information, such as IP address, timestamp, and user agent, in their server logs.

Network-focused products may process traffic needed to provide their requested function. Any material product-specific handling will be documented on that product's page or in an updated policy before release.

Advertising and consent

Where advertising is enabled, apps use Google Mobile Ads and Google's consent tools. Advertising providers may process device identifiers, consent signals, approximate location derived from IP address, and ad interaction data according to their own policies and the choices available on your device.

Advertising is enabled only when the relevant platform configuration is available. Current public configuration distinguishes Android and iOS readiness for every app.

Accounts, membership, and purchases

The current app configuration does not enable a studio account or membership system. If accounts, subscriptions, purchases, or cloud synchronization are introduced, the affected product configuration and this policy will be updated before those features are released.

Children and sensitive information

Do not enter sensitive personal information unless an app explicitly requires it for the feature you chose to use. The apps are not presented as services directed specifically to children.
