Privacy Policy
Last updated: July 2, 2026
In brief: NipponGo does not collect, store, or transmit any personal data. All information (saved guides, bookmarks) is stored locally on your device only and never leaves it. There is no account system and no tracking SDK. Bookmarks are free and unlimited. If you choose to leave an optional tip to support development, that purchase is processed entirely by the Apple App Store or Google Play, and we never see your payment information.
1. General Information
NipponGo ("the App") is a Japan transit guide for first-time Western visitors, developed and published by IOCODO LLC ("we", "our", "us"). It provides an honest JR Pass calculator, per-leg Suica and JR Pass validity on Golden Route itineraries, an offline Survival Kit phrasebook, and curated area guides for Japan's major tourist destinations.
This Privacy Policy explains what information is processed when you use the App and your choices regarding that information.
2. Data We Do Not Collect
NipponGo does not collect any personal data from users. Specifically, the App does not:
- Require or support user accounts, sign-in, or registration of any kind
- Collect names, email addresses, phone numbers, or other identifiers
- Track location data, device identifiers, or advertising IDs
- Use analytics tools, crash reporting SDKs, or usage tracking
- Transmit any data to our servers or any third-party servers
3. Local Data Stored on Your Device
The App uses your device's local storage (iOS UserDefaults / Android SharedPreferences) to remember your preferences and saved content between sessions. This data includes:
- Saved guides and bookmarked routes (free and unlimited)
- App settings and preferences (theme, language, home currency, units)
- Your tip history, if you have chosen to support the app
This data never leaves your device. It is deleted when you uninstall the App.
4. Optional Tips
NipponGo is free to use, with no account required and no limit on saved bookmarks. If you would like to support ongoing development, the app offers optional one-time tips of varying amounts. Each tip is processed entirely by the Apple App Store (iOS) or Google Play (Android). We do not process payments, see your payment information, or store any transaction details on our servers.
Tips are consumable purchases and are not restored or transferred between devices. No purchase data is sent to IOCODO servers.
5. External Links and Affiliate Partners
The App provides links to third-party travel services such as Airalo eSIMs, GetYourGuide, Klook, SafetyWing, and others. These links may include affiliate parameters that help us earn a commission at no extra cost to you. Clicking these links opens the respective partner's website or app in your browser; we do not transmit any personal data to partners. Each partner's own privacy policy governs how they handle your information once you visit their site.
6. External Content
The App may display content from external sources (such as website previews opened in an in-app browser). These external sites operate under their own privacy policies.
7. Data Sharing and Sale
We do not sell personal data because we do not collect any. We do not share any user data with third parties for marketing, advertising, or any other purpose.
8. Children's Privacy
The App is not directed to children under the age of 13. Because we do not collect any personal data from any users, the App is inherently compliant with children's privacy regulations including COPPA.
9. Your Choices
- You can delete all locally stored App data by uninstalling the App from your device.
- To request a refund for a tip purchase, follow your platform's standard refund process (Apple App Store or Google Play).
10. Changes to This Policy
We may update this Privacy Policy from time to time. If we make material changes, we will update the "Last updated" date at the top of this page. Continued use of the App after changes are posted constitutes your acceptance of the updated policy.
