Frequently asked questions

Onedermap is a world map you fill in yourself. Tap the countries you have visited, see what percentage of the world that adds up to, and share the result as an image. You track your travels by hand — the app is not a location tracker and never follows where you go.

Onedermap is available for Android on Google Play today, and the iPhone version is coming to the App Store soon. It is designed for phones.

No. Onedermap opens straight to the map with nothing to sign up for. An account is only involved if you choose to turn on cloud backup, which is off by default.

Yes. The map, the country list, your statistics, and sharing all work with no connection at all, because your countries are stored on your device.

Yes. The interactive map, the searchable country list, your percentage of the world, your statistics, sharing, and cloud backup are all free, with no ads.

Premium is a single one-time purchase, not a subscription. It adds visited cities, states and regions within 34 supported countries, extra map themes including the Google Maps map style, and additional share-card designs.

Use Restore Purchases, in Settings or on the premium screen, with the same Apple or Google account you bought with. Your unlock comes back at no extra charge.

Purchases are handled entirely by Apple and Google, so refunds go through them: use Apple's or Google Play's standard refund process for the platform you bought on. Onedermap never sees your payment details.

No. The app never asks for location permission and never uses your location, precise or approximate. The only places on your map are the ones you tap yourself.

Your list of visited countries stays on your device unless you turn on cloud backup. We do collect anonymous usage statistics and anonymous crash reports so we can see which features are used and fix errors, and neither ever includes where you have been. The Privacy Policy sets out every case in detail.

Settings → Backup & Data → Reset data clears the countries and cities saved on your device. If you turned on cloud backup, Settings → Cloud backup → Delete account & cloud data permanently removes your account and its backup. The Support page covers what to do if you no longer have the app installed.

Yes. Open Settings → Cloud backup, sign in with Apple or Google, and your countries are kept safe and can be restored on any device you sign in on. Cloud backup is free, entirely optional, and off until you switch it on.

The app works exactly the same, and nothing about your map is stored anywhere but your phone. The trade-off is that your countries are not recoverable if you lose the device or delete the app, so back up if that matters to you.

It is the number of countries you have visited divided by the United Nations list of 195 countries — the 193 member states plus Vatican City and Palestine as observers. Every country counts equally, whatever its size. You can still mark territories such as Greenland or Puerto Rico; they appear in your collection without changing that total.

Region tracking is currently available for 34 countries: Argentina, Australia, Austria, Belgium, Brazil, Bulgaria, Canada, China, Colombia, Czechia, Denmark, Finland, France, Germany, Greece, Hungary, India, Ireland, Italy, Japan, Mexico, Netherlands, Pakistan, Peru, Poland, Portugal, Russia, Slovakia, Spain, Sweden, Switzerland, Ukraine, United Kingdom, and United States. We continue to add support for more countries over time.

A few well-known disputed territories can be displayed according to your own preference in Settings, in the interest of honest, transparent cartography. The choice affects only how the map is drawn — never your visited countries, your percentage, or anything that is shared or backed up.
