JapanFam Privacy Policy
Effective date: October 22, 2026
This policy applies to the Android app "JapanFam: Osaka Tokyo Kyoto" (package: com.osakafam.app), referred to as "the app". The app has no user accounts, and the developer does not operate any servers for it. We do not ask for your name, email address or phone number.
Information the app uses
- Photos for AI translation (only if you use this feature). The photo you take or choose is resized and sent over HTTPS to Google's Gemini API to produce a translation. We do not store it. Google processes it under its own terms (https://ai.google.dev/gemini-api/terms). Translations are AI-generated and may be inaccurate.
- Approximate location (optional permission). If you allow it, the app reads your approximate location on your device only to detect whether you are in Tokyo, Osaka or Kyoto. The app does not send your location to any server.
- Weather and exchange rates. The app requests weather for the selected city's fixed coordinates from Open-Meteo and exchange rates from open.er-api.com. These requests contain no personal information, but, as with any internet request, those services can see your IP address.
- Advertising. The app shows ads through Google AdMob. AdMob may collect and use your advertising ID, IP address and device information to deliver and measure ads. You can reset your advertising ID or opt out of ad personalization in your Android settings (for example, Settings > Privacy > Ads).
- Data on your device. Settings and your travel plan are stored on your device only and are deleted when you uninstall the app. Phrase playback uses your device's built-in text-to-speech.
- External links. Links to Google Maps, YouTube, transit operators and other sites open in your browser. Those sites have their own privacy policies.
Sharing
We do not sell your data. Data leaves your device only as described above (Google for Gemini and AdMob, Open-Meteo, and the exchange-rate service).
Your choices
You can deny or revoke the camera and location permissions at any time in Android settings; the related features (photo translation, automatic city detection) will then be unavailable. You can uninstall the app at any time.
Children
The app does not knowingly collect personal information from children.
Changes
If this policy changes, the updated version will be posted on this page with a new effective date.
