Norimachi Privacy Policy

Effective date: July 20, 2026 (draft) / Last updated: October 8, 2026

Overview

RINSAI TECH Inc. ("we," "us," or "our") sets out this Privacy Policy (the "Policy") regarding the handling of user information in our mobile application "Norimachi" (the "App"). The App is an unofficial application that displays bus-approach and timetable information for stops by referencing publicly available operating information published by Nishi-Nippon Railroad Co., Ltd. (Nishitetsu Bus). By design, we collect the minimum information necessary. The App has no user accounts and does not send your device's location (latitude and longitude) to our servers. Only when you search for a route from "Your location" does the App send information about the nearest stop, determined on your device.

Location (your device's latitude and longitude are never transmitted)

Only if you grant permission, the App obtains your device location while the App is in use and uses it to sort and display stops near you and to determine the stop nearest to you when you search for a route from "Your location." Both are processed on your device; your device's location itself (latitude and longitude) is never sent to or stored on our servers, our relay, or any external service. However, when you search for a route from "Your location," the App sends the nearest stop's name, stop code, and public coordinates (the stop's latitude and longitude as published by Japan's Ministry of Land, Infrastructure, Transport and Tourism) to our relay. This information indicates your approximate location. Granting location permission is optional; other features (such as searching for a stop by name) work without it. You may revoke the permission at any time in your device settings.

Information stored on your device (never transmitted)

Your favorite stops, recently viewed stops, and cached stop-resolution results (to speed up display) are stored only in local storage on your device. They are not sent to us and are removed when you delete the App.

Communication to retrieve stop and operating information

When you perform an action that displays a stop's operating information or route search results, the App retrieves the relevant information from Nishitetsu's public website (jik.nishitetsu.jp) via our relay, which runs on Cloudflare Workers. This communication transmits only the search term, stop name, stop code, the stop's public coordinates, and display language; it does not transmit information identifying you, nor your device's location (latitude and longitude). As is inherent to any network communication, your IP address is processed at the network-infrastructure layer (Cloudflare) as standard access logs for the purposes of delivering the request, preventing abuse, and security. To investigate problems and keep the relay running stably, we keep records of communications through the relay (the content transmitted, date and time, etc.) for up to 7 days, after which they are automatically deleted. To improve the translation of stop names, we also keep statistics of the stop names displayed and how often each was displayed, without any information identifying you, for up to 3 months. To monitor the relay's operating status and detect problems early, we use the error-monitoring service "Sentry" (provided by Functional Software, Inc.) for fault monitoring of our own server (the relay). This is equivalent to our server's operational logs / fault monitoring, not a transmission from your device. The information recorded is limited to technical diagnostic data — the type of error, which relay function was involved (e.g., search vs. arrivals), public stop/route codes, and the length/heading of the source page. Any free-text search term you typed is masked before transmission, and the content of the upstream page is limited to its heading and an excerpt of 300 characters or fewer. No information identifying you personally is included. Purpose: Providing the App's core function (displaying bus-approach, timetable, and route information); stable operation and security of the communication infrastructure; improving the translation of stop names.

Information related to advertising

The App displays advertisements using Google's advertising service, Google AdMob (Google Mobile Ads SDK). The App serves non-personalized ads only. On iOS, the App does not ask for permission to track you (App Tracking Transparency). Even for non-personalized ads, Google collects and processes information such as your IP address (including coarse, city-level location estimation), device identifiers, information about app launches and ad impressions and interactions, and diagnostic information about how the App performs, for ad delivery, limiting how often an ad is shown, aggregated reporting, and fraud prevention. On iOS, the advertising identifier (IDFA) is not used; app-scoped identifiers and similar are used instead. On Android, the Android advertising ID and app set ID are used. You can reset or delete your Android advertising ID at any time in your device settings. Google handles this information in accordance with its own privacy policy. Purpose: Delivering non-personalized ads within the App; measuring ad quality and delivery; fraud prevention.

Information related to app stability (crash reporting)

To identify and fix app crashes and runtime errors and to improve quality, the App incorporates the crash-reporting service "Sentry" (provided by Functional Software, Inc.). The SDK is included when the App starts, and when a crash or error occurs, the following technical diagnostic information is transmitted to Sentry's servers (located in the United States): Crash reports / error information (e.g., stack traces) Your device's model name and OS version The App's version Whether app sessions ended normally or crashed (so-called "release health" information) A random identifier generated for each installation of the App (not linked to you personally) We do not intentionally attach information that identifies you — such as your name, email address, or a user ID — to this transmission. As is inherent to any network communication, the source IP address is processed by Sentry's network infrastructure in order to deliver the request, but we do not intentionally collect or attach it as diagnostic data. The App does not enable performance tracing or session replay (screen-recording-like functionality). This transmission does not occur in development builds. Recipient: Functional Software, Inc. (d/b/a Sentry) Information transmitted: as described above (crash/error information, device model, OS/app version, whether the session ended normally or crashed, an identifier for each installation) Purpose: Identifying and fixing app crashes/errors; improving app stability.

In-app problem reports (information you choose to send)

Only if you send a report from the App's "Report a Problem" form, what you entered is transmitted to and stored on Sentry's servers (located in the United States) through the user-feedback feature of the same Sentry service described in "Information related to app stability (crash reporting)" above (provided by Functional Software, Inc.) The following is transmitted: The text of the report you wrote Your email address, only if you filled in the optional "Contact" field Technical information for diagnosis: the App's version, your device's OS version, and the App's display language Transmission happens only when you tap "Send"; nothing is sent automatically. Providing contact details is optional, and you can send a report without them. Because the report body is a free-text field, please avoid entering personal information such as your name or phone number beyond what is needed for a reply. Recipient: Functional Software, Inc. (d/b/a Sentry) Purpose: Reviewing and acting on the issue or feedback you reported, improving the App's quality, and replying to you if you provided contact details.

Responding to inquiries

If you contact us (e.g., by email), we handle your email address and the content of your inquiry in order to respond. Purpose: Responding to your inquiry.

Provision to Third Parties / Processors

Except as required by law, we do not provide your personal information to third parties. However, to operate the App we use the following external services, and information is processed by them accordingly: Google LLC (Google AdMob) — Non-personalized ad delivery, measurement, fraud prevention: IP address, device identifiers, ad-related information (see "Information related to advertising" above) Cloudflare, Inc. — Relay (communication infrastructure), security: Access logs including IP address associated with the request Functional Software, Inc. (Sentry) — App crash reporting / quality improvement, receiving in-app problem reports, and fault monitoring of our own relay server: Crash reports, device model, OS/app version, session status, and other diagnostic information. For problem reports: the text you wrote, your email address if you provided one, and the App's version, your device's OS version, and display language. For the relay: error type and public stop/route codes and similar technical information (your search text is masked before transmission and is not included)

Cross-Border Transfer

Google LLC, Cloudflare, Inc., and Functional Software, Inc. (Sentry) referenced above are all located outside Japan (primarily in the United States), and using these services may involve transferring information outside Japan. Each provider implements measures to protect personal information under its own privacy policy and the applicable data-protection framework.

Security Measures

We implement necessary and appropriate measures to prevent leakage, loss, or damage of the information we handle, including encryption of communications (HTTPS). Your device's location (latitude and longitude) and on-device stored data are processed only on your device and are not sent to our servers, structurally minimizing leakage risk on our side.

Disclosure, Correction, and Suspension of Use

By design, we hold almost no personal data in a form that identifies a specific individual (your device's latitude and longitude never leave the device, and there are no accounts). Nevertheless, if you request disclosure, correction, addition, deletion, or suspension of use of personal data we hold, we will respond without undue delay in accordance with applicable law, after verifying your identity. You may also ask us to delete what you sent us in a problem report or inquiry, including your email address. Please send requests to [email protected]. We keep problem reports only as long as needed to respond and improve the App. Crash and error information is automatically deleted within 90 days.

Children's Privacy

The App is not directed to children in particular, and we do not knowingly collect personal information from children.

Users Outside Japan (GDPR, etc.)

The App is primarily intended for use within Japan, but may be used by users in the European Economic Area (EEA), the United Kingdom, and other regions, such as travelers visiting Japan. We keep the information we collect to a minimum, do not transmit your device's location (latitude and longitude) off the device, and do not serve personalized ads. Users in the EEA, the UK, and similar jurisdictions may have rights under applicable law to access, correct, or delete their personal data. Please use the contact below for such requests.

Changes to this Policy

We may amend this Policy in response to changes in law or the App's features. If we make material changes, we will announce them in the App or on this page.
