PRIVACY POLICY

Last revised: October 13, 2026

This privacy policy explains how information is handled by the website and iOS and macOS apps provided by Tomoya Hasegawa / JIRMRU’s Imaginary Republic (the “Operator”). The information and external services used depend on the app’s features, version and settings.

Information used by app features

The apps use the following information to provide features, according to the actions and permissions you choose. An app accessing information on your device is a separate process from information being sent to the Operator or an external service.

• FineFinder: Uses the names, locations and contents of selected files and folders for browsing, moving, copying, renaming, compression and extraction. It also saves workspaces and settings. Working with network or cloud-synced folders may involve communication or syncing managed by your OS or the connected service. Support buttons open external websites in your default browser.
• Calun: Reads and writes events and calendars through the OS calendar framework to display calendars and edit events. Contact-related screens display contacts with your permission. Syncing with iCloud, Google Calendar or other services is managed by the OS or the services you configure.
• Walking! Earth Defence Force: Uses Motion & Fitness step counts for game progress. If you enable the optional Health integration, it reads step counts from HealthKit. Step counts and HealthKit data are used for game features, not for advertising targeting. It also saves game progress and settings.
• X-remo: Uses authorized HomeKit home, accessory and scene information to display and control devices. Web API features use the URLs and connection settings you specify to send commands to local devices or external services. The destination, request contents and protection of these connections also depend on your settings and the connected service.
• How long in my microwave?: Uses the microwave power and heating time you enter to calculate equivalent heating times.

Development of Z-remo has ended. If you continue using an older version, its information handling may vary with that version’s features, settings and OS. Please also read the advertising and analytics section below.

Visits to this website

This website uses Star’s web hosting service. Server logs may record information such as IP addresses, access times, requested pages and browser details to deliver the site, maintain it and protect against unauthorized access. Log retention depends on the hosting service and server settings.

The public website uses Google Analytics 4 (GA4) to understand visits and improve the site. Cookies and similar technologies are used to send information such as pages viewed, interactions on the site, and device or browser details to Google. The site’s measurement tag disables Google Signals and advertising personalization. This website analytics is separate from advertising and Firebase analytics within the apps.

See the Google Privacy Policy for details. On supported browsers, you can use the Google Analytics Opt-out Browser Add-on. You can manage cookies in your browser settings, but restricting cookies alone does not necessarily stop all communication or measurement.

The site uses externally hosted Google Fonts. Your browser contacts Google to load fonts, sending information such as your IP address and browser details. See the Google Privacy Policy for Google’s handling of this information.

Advertising and usage analytics

Calun, Walking! Earth Defence Force, X-remo, How long in my microwave? and older versions of Z-remo use Google AdMob. The SDK may collect and send device or app identifiers, IP addresses, ad views and interactions, and crash or performance diagnostics to Google and other service providers for ad delivery, measurement, fraud prevention and service improvement. IP addresses may also be used to estimate a general location. The data collected depends on the SDK version, OS, consent and settings.

X-remo and older versions of Z-remo also use Google Analytics for Firebase. Automatically recorded usage events, app-instance identifiers and device or app information are sent to Google to understand usage and improve features. This is separate from analytics for visits to this website.

For details, see AdMob SDK data disclosures, Privacy and Security in Firebase and the Google Privacy Policy.

Purchases and support

Apple processes App Store purchases and in-app payments. Apps use purchase status and transaction information to provide and restore purchased features. This does not give the Operator direct access to your card number or similar payment credentials.

Ko-fi support is handled through Ko-fi and payment providers. The Operator may receive your display name, email address, support amount and other transaction information. Payment providers may share additional details depending on the payment method. This information is used to confirm support, send thanks, respond to inquiries and carry out necessary accounting. It is not used for advertising or newsletters. See the Ko-fi Privacy Policy and your payment provider’s information.

Information you provide when contacting us

Account names, contact details and inquiry contents you provide are used to respond, investigate issues and keep records of our responses. Conversations in public posts and use of external sites are also subject to those services’ terms and privacy policies. The same applies to external services linked from this site, such as note, app stores and X.

Sharing and security

The Operator shares personal information it holds where permitted by law, such as with your consent, when entrusting necessary work to a service provider, or as required by law. Processing by the advertising, analytics and payment services described above follows their respective explanations and privacy policies. External services may process information outside Japan.

The Operator works to protect the information it holds against unauthorized access and disclosure, including by managing access to that information. When work is entrusted to a service provider, the Operator selects and manages the provider according to the information involved.

Retention, deletion and withdrawal of permissions

The Operator keeps inquiry, support and similar information for as long as needed for its stated purposes or as required by law. Information no longer needed is deleted or made non-identifying. Server logs are retained according to the hosting service and settings; external services retain information under their own policies.

You can manage or delete data stored on your device through the app or OS. On macOS, removing an app may leave settings or saved data behind, which may need to be deleted separately. Manage data and backups held by calendars, cloud services or other connected services through the relevant OS or service.

You can change access permissions for calendars, contacts, Motion & Fitness and HomeKit through OS settings, and HealthKit permissions through the Health app or relevant settings. You can also change advertising tracking permission in iOS settings. Withdrawing that permission does not necessarily stop all communication, including non-personalized ads or usage analytics. Changing permissions may make some features unavailable.

To request access, correction, deletion or an end to the use of information held by the Operator, contact us using the details below. We may ask for information needed to identify the relevant records and verify your identity. Information that must be retained by law or similar requirements may not be deleted. For information held by an external service, also check that service’s controls and contact options.

Changes and contact

We review this policy as features and services change. Updates and revision dates are posted on this page, with additional notice or consent where required by law.

For privacy inquiries or requests such as deletion, contact @jirmru on X. Do not include email addresses, payment details or personal information from an app in public posts. Please first ask how to contact us safely.
