Metro Maps — Privacy Policy
Metro Maps shows subway networks for several cities and plans journeys across them, offline. This policy explains what happens to your information.
Summary
- There is no account and no sign-up.
- Your chosen city, recent journeys and settings are stored only on your phone.
- There is no analytics, no crash reporting, no advertising and no tracking.
- The network data, timetables and fares are bundled inside the app, so journey planning works with no connection at all.
- Two optional things can leave your device, and only if you use them: your approximate location, and street map tiles. Both are described below.
What stays on your device
- Your city, and the language you picked.
- Recent and saved journeys: the stations you chose.
- Your settings: theme and preferences.
All of it sits in the app's private storage, which Android does not let other apps read. Android Auto Backup is disabled. Uninstalling removes everything.
Location (optional)
If you ask the app to find the nearest station, it requests your approximate location — coarse, not precise. The coordinates are used on the device to measure distance to stations in the bundled data, and are not stored and not sent anywhere. Decline the permission and every other part of the app still works; you simply pick your station from the list.
Street map tiles (optional)
Where the app shows a street map rather than the subway diagram, the map images come from MapTiler. Your device requests image tiles for the area being shown, so MapTiler necessarily receives your IP address and which tiles you asked for, under their privacy policy. No identifier of yours is attached, and nothing about your journeys is sent. The subway map, routing, fares and times are all drawn from data inside the app and need no connection.
Where the data comes from
Network, timetable and fare data is built from each operator's published open data. The licence for every city is recorded in the app's own source repository, and a city whose data could not be licensed was left out rather than copied.
Metro Maps is not affiliated with, endorsed by, or operated by any transit authority. Always check the operator's own information for live service changes.
Children
Metro Maps is not directed at children under 13 and collects nothing from anyone.
Your rights
Laws such as the GDPR and the DPDP Act give you rights over personal data held about you. We hold none. Your data is on your phone: clear it in the app, or uninstall, and it is gone.
Changes
If this policy changes, the effective date above changes with it.
