Privacy Policy

Last updated: June 30, 2026

Manner Navi Japan collects no data. The app has no servers, makes no network connections, and contains no tracking, analytics, advertising, or accounts. Nothing about you or your device is ever sent anywhere.

Manner Navi Japan ("the App") is developed and operated by Lumina AI Co. This Privacy Policy explains how the App handles information. Because the App is fully offline, the short answer is: it does not collect, transmit, or share any information at all.

1. Data We Collect

None. The App does not collect any personal data or usage data. It does not connect to the internet, so no information ever leaves your device.

We do not collect your name, email address, or any personally identifiable information.
We do not collect or access your location.
We do not use advertising identifiers (IDFA / GAID) and do not show ads.
We do not use analytics, crash reporting, or any third-party tracking SDKs.
We do not require or offer any account or sign-in.

2. Information Stored On Your Device

The App stores one setting locally on your device: your preferred display language. This is saved in the device's standard app preferences (UserDefaults) so the App opens in your chosen language. It never leaves your device and is removed when you delete the App. All etiquette content (10 categories, 71 cards) is bundled inside the App itself and is read locally.

3. Third-Party Services

The App uses no third-party services, SDKs, or analytics. It does not connect to any external server or API. The map, AI, and crowd-sourcing features found in some other apps are not present in Manner Navi.

4. Network and Permissions

The App requests no special permissions (no location, no camera, no contacts, no notifications) and performs no network requests. It runs entirely offline.

5. Children's Privacy

The App is suitable for all ages and, because it collects no data whatsoever, it collects no information from children under 13.

6. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be reflected by updating the "Last updated" date above. If the App's data practices ever change, this policy will be updated before that change ships.
