Privacy Policy

Last updated: November 12, 2026

Ryo Tsuzukihashi (the “Operator”) handles user information in the app “Focus Railway” (Japanese name: 集中電鉄; the “App”) as described below.

The App has no accounts, and the Operator has no servers that hold user information. The only information sent out of the App is the advertising-related information described in Section 3, and only when the App is used for free.

1. Information Stored Only on Your Device

The following information is stored only on your device. The Operator does not receive it.

• Your focus records (the stations where you boarded and got off, focus time, number of stops, distance, and the date and time of the ride) and your running totals
• The state of a ride in progress (how far you have ridden, and whether it is paused)
• Settings (cabin sound, window side, time of day, weather, Lite Mode, app language, Home Screen icon, and whether you have seen the first-time guide)
• A record used to avoid showing full-screen ads too often (the number of rides, and when one was last shown)

2. Information the App Does Not Use

• The App does not ask for location permission. The scenery outside the window is drawn from map data bundled in the App and does not use your current location.
• The App does not use your camera, microphone, photos, contacts, calendar, or health information.
• The voice of the cabin announcements is generated on your device using the device’s speech feature. It is not sent anywhere.
• The Operator has not built its own usage analytics or crash reporting into the App. If you have turned on “Share With App Developers” in your device settings, Apple may show the Operator crash and usage information that has been aggregated so that it cannot identify individuals.

3. Information Sent for Advertising

If you have not purchased Premium, the App shows ads using Google LLC’s advertising service “Google AdMob” (the Google Mobile Ads SDK) and its consent management tool “Google User Messaging Platform”. When it does, the following information is sent from the App to Google and its advertising partners.

This information is processed on Google’s servers in the United States and other countries. For how Google handles it, see How Google uses information from sites or apps that use our services and Google’s Privacy Policy.

Your focus records, the stations you rode between, and your settings are not sent for advertising.

If you have purchased Premium, the App does not load ads, so the information in this section is not sent.

4. Your Choices About Advertising

• Permission to track (App Tracking Transparency): The App asks once for permission to track, in order to show ads suited to you. Saying no changes nothing about the lines or the views you can ride. If you decline, the advertising identifier is not sent. To change your choice later, open Settings → Privacy & Security → Tracking on your iPhone or iPad.
• Consent screen: In regions where the law requires consent, such as the European Economic Area, the United Kingdom, and Switzerland, the App shows a consent screen before showing ads. You can revisit your choices at any time from “Ad privacy settings” under “About This App” in the App’s Settings.
• No ads: If you purchase Premium, ads are not shown and no advertising-related information is sent.

The App also supports Apple’s SKAdNetwork, a mechanism from Apple that reports the results of ads to advertisers without identifying individuals.

5. Purchases

Purchases of Premium are made through Apple’s App Store. Payment information (such as credit card numbers) and the purchaser’s name are not provided to the Operator. The App checks on your device, using Apple’s system (StoreKit), whether Premium is active. For how Apple handles purchase information, see Apple’s Privacy Policy.

6. Sharing

The share image created when you arrive (a station sign with your focus time, number of stops, distance, and so on) is passed to a destination only when you tap the share button and choose that destination. What happens to it afterward is governed by the policy of the service you send it to.

7. About This Website

This website is served by Google’s Firebase Hosting. When you open a page, access records such as your IP address and the page you viewed are kept by Google in order to serve the site. The Operator has not placed any analytics or tracking cookies or tags on this website. The language of the pages switches automatically to match your browser’s language setting.

8. Disclosure to Third Parties

Because the Operator does not receive information that can identify users, it does not disclose such information to third parties. The information in Section 3 is sent directly from the App to Google.

9. Retention and Deletion

• The information on your device (Section 1) is erased when you delete the App.
• Information that Google stores for advertising is kept for the period Google determines. The advertising identifier stops being sent once you withdraw permission to track.

10. Children

The App is not designed specifically for children. The Operator does not knowingly collect personal information from children.

11. Contact

If you have questions about this Policy or about how information is handled, please contact the address below. Where the Operator holds information about you (for example, an email you sent), it will respond to requests for disclosure, correction, or deletion after confirming your identity.

12. Changes to This Policy

This Policy may be changed as needed. The changed Policy takes effect when it is posted on this page. Important changes will be announced in the App or on this website.
