Terms of Use

Last updated: November 12, 2026

These Terms of Use (the “Terms”) set out the conditions for using the app “Focus Railway” (Japanese name: 集中電鉄; the “App”) and this website (together, the “Service”), provided by Ryo Tsuzukihashi (the “Operator”). By using the Service, you are deemed to have agreed to these Terms.

Article 1 (The Service)

1. The App is a timer for focusing while you watch the scenery from a train window. The time from the station where you board to the station where you get off becomes your focus time.
2. The App can be used without creating an account. Your focus records and settings are stored on your device.
3. The App is free to use. Some features become available when you purchase the paid features (Premium) described in Article 3.

Article 2 (Scenery, Sound, and Names)

1. The scenery in the App is a three-dimensional rendering created by the Operator from map data (OpenStreetMap). The look, height, and signage of buildings, the cars on the roads, the people at stations, and similar details differ from reality.
2. Travel times and stopping times in the App are calculated from the shape of the track and differ from actual train operations, timetables, and platforms. The App cannot be used as a timetable, route planner, or source of service information.
3. The App is not provided, supervised, or endorsed by any railway company. Line names, station names, and station numbers are used as factual names. The designs of the station signs and the displays above the doors, the cabin sounds, and the announcements were created for the App.

Article 3 (Premium (Paid Features))

1. With Premium, you can choose your stop and direction, choose the window side, time of day, and weather, change the Home Screen icon, and use the App without ads. The details are shown on the purchase screen.
2. Premium is offered as auto-renewing subscriptions (monthly and yearly) and as a one-time lifetime purchase. Prices and periods are shown on the purchase screen. There is no free trial.
3. Payment is made through Apple’s App Store. Your Apple Account is charged when you confirm the purchase.
4. A subscription renews automatically for the same period and at the same price unless auto-renewal is turned off at least 24 hours before the end of the current period. The renewal is charged within 24 hours before the end of the current period.
5. You can turn off auto-renewal at any time from Settings → your name → Subscriptions on your iPhone or iPad. If you turn it off partway through a period, you can still use Premium until that period ends. No prorated refunds are given.
6. A lifetime purchase can be restored with “Restore Purchases” on the purchase screen, on any device signed in with the same Apple Account.
7. Refunds after purchase are handled as determined by Apple. The Operator cannot issue refunds directly.
8. When a subscription ends, Premium features are no longer available and the Home Screen icon returns to the standard one. Your focus records are not deleted.

Article 4 (Advertising)

1. If you have not purchased Premium, the App shows ads delivered by a third party (Google AdMob). Ads appear at the station, while stopped at stations along the way, after you arrive, and on the Settings screen. They are not shown while the train is moving.
2. The content of ads, and the pages and apps opened from them, are provided by the respective advertisers. The Operator is not responsible for that content or for any transactions made there.

Article 5 (Using the App Safely)

1. Do not use the App while walking, or while driving a car, riding a bicycle, or operating any other vehicle.
2. While you ride, the App keeps the screen on and keeps drawing the scenery. Using it for a long time can drain the battery and make your device warm. If this concerns you, use Lite Mode in Settings, and if you use the App while charging, do so in a well-ventilated place.
3. If watching the moving scenery makes you feel unwell or strains your eyes, stop using the App and rest.

Article 6 (Prohibited Conduct)

You must not do any of the following.

• Acts that violate laws or public order and morals
• Analyzing or modifying the App, or extracting and distributing data or materials from the App (except where permitted by law)
• Using paid features by improper means
• Infringing the rights or interests of the Service or of third parties
• Presenting the App as if it were an official product of a railway company
• Any other act the Operator judges to be inappropriate

Article 7 (Ownership)

1. Rights in the App’s program, screens, artwork, sounds, and text belong to the Operator or to their legitimate rights holders.
2. The map data in the App is © OpenStreetMap contributors and is made available under the Open Database License (ODbL). See openstreetmap.org/copyright for details.
3. You may post images of the App’s screens, and the share image created when you arrive, on social media and similar services as an individual. When you do, please do not describe the App as if it were an official product of a railway company.

Article 8 (Changes to and End of the Service)

The Operator may change the content of the Service or stop providing it without notice to users. If the paid features are to be discontinued, the Operator will give advance notice in the App or on this website.

Article 9 (Disclaimer)

1. The Operator does not guarantee that the Service will suit your particular purpose, be free of defects, or be available without interruption.
2. Your focus records and settings are stored only on your device. They may be lost if you delete the App, or reset or replace your device. The Operator cannot recover them.
3. The Operator is not liable for damage you suffer from using the Service, except where it is caused by the Operator’s willful misconduct or gross negligence.
4. The preceding paragraph does not apply where the Consumer Contract Act of Japan or other laws do not allow the Operator’s liability to be excluded or limited.

Article 10 (Apps Obtained from the App Store)

1. These Terms are an agreement between you and the Operator, not with Apple Inc. (“Apple”). The Operator, not Apple, is responsible for the App and its content.
2. The Operator grants you a non-transferable license to use the App on Apple-branded devices that you own or control, within the scope of these Terms and the usage rules set by Apple.
3. Apple has no obligation to provide maintenance or support for the App. If the App fails to conform to any applicable warranty, you may notify Apple, and Apple may refund the purchase price, if any; Apple has no other warranty obligation with respect to the App.
4. The Operator, not Apple, is responsible for addressing any claims by you or a third party relating to the App, including product liability claims, claims that the App fails to conform to legal requirements, claims under consumer protection laws, and claims that the App infringes intellectual property rights.
5. You represent that you are not located in a country or region subject to a U.S. Government embargo, and that you are not listed on any U.S. Government list of prohibited or restricted parties.
6. Apple and its subsidiaries are third-party beneficiaries of these Terms and, upon your acceptance of these Terms, have the right to enforce them against you as third-party beneficiaries.

Article 11 (Changes to These Terms)

The Operator may change these Terms as needed. The changed Terms take effect when they are posted on this page. Important changes will be announced in the App or on this website.

Article 12 (Governing Law and Jurisdiction)

These Terms are governed by the laws of Japan. Any dispute relating to the Service is subject to the exclusive jurisdiction of the Tokyo District Court as the court of first instance. However, where the laws of the country in which you live provide otherwise, those laws apply.
