Privacy Policy

On My Line for iPhone
Last updated 21 September 2026

On My Line shows which towns and geographic features sit on the same latitude and longitude as you. It has no accounts, no servers of its own, and no advertising. This policy describes exactly what the app does with data, because the short version — it collects nothing — deserves an explanation of why that is true.

Data we collect

None. The developer operates no server, receives no data from the app, and uses no analytics, tracking, attribution or advertising frameworks. The app contains no third-party SDKs.

Your location

If you grant location access, the app asks iOS for your approximate position (accuracy of about 100 metres — the app does not need more) to work out which places lie on your latitude and longitude. That position is used on your device and is never transmitted to the developer or to anyone else.

Location access is optional. Without it the app is fully usable: you can pick any point by searching for a place, typing coordinates, or pressing and holding the map.

The place database

The list of places ships inside the app as an offline database. Searching, computing your parallel and meridian, and finding your antipode all happen on your device, without a network connection.

Optional online content

When you open a place card, and only if “Online content” is switched on in Settings, the app makes requests to three public services:

• Wikipedia (en.wikipedia.org) — the app sends the article title of the place you opened, to fetch a short summary.
• Wikimedia Commons (commons.wikimedia.org) — the app sends the file name of the photo shown in the summary, to fetch its author and licence. No attribution, no photo.
• Open-Meteo (api.open-meteo.com) — the app sends the coordinates of the place you opened, to fetch its current weather.

These services receive your device's IP address, as any website does, and handle it under their own privacy policies: Wikimedia Foundation and Open-Meteo. The requests carry no identifier, no account and no advertising ID.

One honest caveat: the coordinates sent to Open-Meteo belong to the place you are reading about, not to you. But if that place happens to be the one nearest to you, those coordinates indirectly indicate your location to within a city. Switching “Online content” off in Settings stops every network request the app makes, and the app then works entirely offline.

Maps

Maps are drawn with Apple's MapKit, which loads map tiles from Apple. That traffic is handled by Apple under Apple's privacy policy; the developer receives nothing from it.

What is stored on your device

• Your settings — units, temperature scale, which kinds of place to show, and whether online content is enabled.
• A cache of summaries, photo credits and weather, so that reopening the same place does not repeat a request. Summaries are kept up to 30 days, weather up to one hour.

All of it lives in the app's own storage on your iPhone, is never uploaded, and is removed when you delete the app.

Children

The app is suitable for all ages, contains no user-generated content and no advertising, and collects no data from anyone, including children.

Changes

If this policy changes, the updated version will be published on this page with a new date. Material changes will also be noted in the App Store release notes.
